+# Engine.IO client
+
+[](https://github.com/socketio/engine.io-client/actions)
+[](http://badge.fury.io/js/engine.io-client)
+
+This is the client for [Engine.IO](http://github.com/socketio/engine.io),
+the implementation of transport-based cross-browser/cross-device
+bi-directional communication layer for [Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Standalone
+
+You can find an `engine.io.js` file in this repository, which is a
+standalone build you can use as follows:
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+ // eio = Socket
+ var socket = eio('ws://localhost');
+ socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+ });
+</script>
+```
+
+### With browserify
+
+Engine.IO is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the client package
+
+ ```bash
+ $ npm install engine.io-client
+ ```
+
+1. write your app code
+
+ ```js
+ var socket = require('engine.io-client')('ws://localhost');
+ socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+ });
+ ```
+
+1. build your app bundle
+
+ ```bash
+ $ browserify app.js > bundle.js
+ ```
+
+1. include on your page
+
+ ```html
+ <script src="/path/to/bundle.js"></script>
+ ```
+
+### Sending and receiving binary
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+ var socket = new eio.Socket('ws://localhost/');
+ socket.binaryType = 'blob';
+ socket.on('open', function () {
+ socket.send(new Int8Array(5));
+ socket.on('message', function(blob){});
+ socket.on('close', function(){ });
+ });
+</script>
+```
+
+### Node.JS
+
+Add `engine.io-client` to your `package.json` and then:
+
+```js
+var socket = require('engine.io-client')('ws://localhost');
+socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+});
+```
+
+### Node.js with certificates
+```js
+var opts = {
+ key: fs.readFileSync('test/fixtures/client.key'),
+ cert: fs.readFileSync('test/fixtures/client.crt'),
+ ca: fs.readFileSync('test/fixtures/ca.crt')
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+});
+```
+
+### Node.js with extraHeaders
+```js
+var opts = {
+ extraHeaders: {
+ 'X-Custom-Header-For-My-Project': 'my-secret-access-token',
+ 'Cookie': 'user_session=NI2JlCKF90aE0sJZD9ZzujtdsUqNYSBYxzlTsvdSUe35ZzdtVRGqYFr0kdGxbfc5gUOkR9RGp20GVKza; path=/; expires=Tue, 07-Apr-2015 18:18:08 GMT; secure; HttpOnly'
+ }
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+});
+```
+
+## Features
+
+- Lightweight
+- Runs on browser and node.js seamlessly
+- Transports are independent of `Engine`
+ - Easy to debug
+ - Easy to unit test
+- Runs inside HTML5 WebWorker
+- Can send and receive binary data
+ - Receives as ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer
+ in Node
+ - When XHR2 or WebSockets are used, binary is emitted directly. Otherwise
+ binary is encoded into base64 strings, and decoded when binary types are
+ supported.
+ - With browsers that don't support ArrayBuffer, an object { base64: true,
+ data: dataAsBase64String } is emitted on the `message` event.
+
+## API
+
+### Socket
+
+The client class. Mixes in [Emitter](http://github.com/component/emitter).
+Exposed as `eio` in the browser standalone build.
+
+#### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `binaryType` _(String)_ : can be set to 'arraybuffer' or 'blob' in browsers,
+ and `buffer` or `arraybuffer` in Node. Blob is only used in browser if it's
+ supported.
+
+#### Events
+
+- `open`
+ - Fired upon successful connection.
+- `message`
+ - Fired when data is received from the server.
+ - **Arguments**
+ - `String` | `ArrayBuffer`: utf-8 encoded data or ArrayBuffer containing
+ binary data
+- `close`
+ - Fired upon disconnection. In compliance with the WebSocket API spec, this event may be
+ fired even if the `open` event does not occur (i.e. due to connection error or `close()`).
+- `error`
+ - Fired when an error occurs.
+- `flush`
+ - Fired upon completing a buffer flush
+- `drain`
+ - Fired after `drain` event of transport if writeBuffer is empty
+- `upgradeError`
+ - Fired if an error occurs with a transport we're trying to upgrade to.
+- `upgrade`
+ - Fired upon upgrade success, after the new transport is set
+- `ping`
+ - Fired upon _flushing_ a ping packet (ie: actual packet write out)
+- `pong`
+ - Fired upon receiving a pong packet.
+
+#### Methods
+
+- **constructor**
+ - Initializes the client
+ - **Parameters**
+ - `String` uri
+ - `Object`: optional, options object
+ - **Options**
+ - `agent` (`http.Agent`): `http.Agent` to use, defaults to `false` (NodeJS only)
+ - `upgrade` (`Boolean`): defaults to true, whether the client should try
+ to upgrade the transport from long-polling to something better.
+ - `forceJSONP` (`Boolean`): forces JSONP for polling transport.
+ - `jsonp` (`Boolean`): determines whether to use JSONP when
+ necessary for polling. If disabled (by settings to false) an error will
+ be emitted (saying "No transports available") if no other transports
+ are available. If another transport is available for opening a
+ connection (e.g. WebSocket) that transport
+ will be used instead.
+ - `forceBase64` (`Boolean`): forces base 64 encoding for polling transport even when XHR2 responseType is available and WebSocket even if the used standard supports binary.
+ - `enablesXDR` (`Boolean`): enables XDomainRequest for IE8 to avoid loading bar flashing with click sound. default to `false` because XDomainRequest has a flaw of not sending cookie.
+ - `withCredentials` (`Boolean`): defaults to `true`, whether to include credentials (cookies, authorization headers, TLS client certificates, etc.) with cross-origin XHR polling requests.
+ - `timestampRequests` (`Boolean`): whether to add the timestamp with each
+ transport request. Note: polling requests are always stamped unless this
+ option is explicitly set to `false` (`false`)
+ - `timestampParam` (`String`): timestamp parameter (`t`)
+ - `policyPort` (`Number`): port the policy server listens on (`843`)
+ - `path` (`String`): path to connect to, default is `/engine.io`
+ - `transports` (`Array`): a list of transports to try (in order).
+ Defaults to `['polling', 'websocket']`. `Engine`
+ always attempts to connect directly with the first one, provided the
+ feature detection test for it passes.
+ - `transportOptions` (`Object`): hash of options, indexed by transport name, overriding the common options for the given transport
+ - `rememberUpgrade` (`Boolean`): defaults to false.
+ If true and if the previous websocket connection to the server succeeded,
+ the connection attempt will bypass the normal upgrade process and will initially
+ try websocket. A connection attempt following a transport error will use the
+ normal upgrade process. It is recommended you turn this on only when using
+ SSL/TLS connections, or if you know that your network does not block websockets.
+ - `pfx` (`String`|`Buffer`): Certificate, Private key and CA certificates to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+ - `key` (`String`): Private key to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+ - `passphrase` (`String`): A string of passphrase for the private key or pfx. Can be used in Node.js client environment to manually specify certificate information.
+ - `cert` (`String`): Public x509 certificate to use. Can be used in Node.js client environment to manually specify certificate information.
+ - `ca` (`String`|`Array`): An authority certificate or array of authority certificates to check the remote host against.. Can be used in Node.js client environment to manually specify certificate information.
+ - `ciphers` (`String`): A string describing the ciphers to use or exclude. Consult the [cipher format list](http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT) for details on the format. Can be used in Node.js client environment to manually specify certificate information.
+ - `rejectUnauthorized` (`Boolean`): If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Can be used in Node.js client environment to manually specify certificate information.
+ - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+ (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+ - `threshold` (`Number`): data is compressed only if the byte size is above this value. This option is ignored on the browser. (`1024`)
+ - `extraHeaders` (`Object`): Headers that will be passed for each request to the server (via xhr-polling and via websockets). These values then can be used during handshake or for special proxies. Can only be used in Node.js client environment.
+ - `onlyBinaryUpgrades` (`Boolean`): whether transport upgrades should be restricted to transports supporting binary data (`false`)
+ - `forceNode` (`Boolean`): Uses NodeJS implementation for websockets - even if there is a native Browser-Websocket available, which is preferred by default over the NodeJS implementation. (This is useful when using hybrid platforms like nw.js or electron) (`false`, NodeJS only)
+ - `localAddress` (`String`): the local IP address to connect to
+ - **Polling-only options**
+ - `requestTimeout` (`Number`): Timeout for xhr-polling requests in milliseconds (`0`)
+ - **Websocket-only options**
+ - `protocols` (`Array`): a list of subprotocols (see [MDN reference](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols))
+- `send`
+ - Sends a message to the server
+ - **Parameters**
+ - `String` | `ArrayBuffer` | `ArrayBufferView` | `Blob`: data to send
+ - `Object`: optional, options object
+ - `Function`: optional, callback upon `drain`
+ - **Options**
+ - `compress` (`Boolean`): whether to compress sending data. This option is ignored and forced to be `true` on the browser. (`true`)
+- `close`
+ - Disconnects the client.
+
+### Transport
+
+The transport class. Private. _Inherits from EventEmitter_.
+
+#### Events
+
+- `poll`: emitted by polling transports upon starting a new request
+- `pollComplete`: emitted by polling transports upon completing a request
+- `drain`: emitted by polling transports upon a buffer drain
+
+## Tests
+
+`engine.io-client` is used to test
+[engine](http://github.com/socketio/engine.io). Running the `engine.io`
+test suite ensures the client works and vice-versa.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul). You can
+run the tests locally using the following command.
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+Additionally, `engine.io-client` has a standalone test suite you can run
+with `make test` which will run node.js and browser tests. You must have zuul setup with
+a saucelabs account.
+
+## Support
+
+The support channels for `engine.io-client` are the same as `socket.io`:
+ - irc.freenode.net **#socket.io**
+ - [Google Groups](http://groups.google.com/group/socket_io)
+ - [Website](http://socket.io)
+
+## Development

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# ws: a Node.js WebSocket library
+
+[](https://www.npmjs.com/package/ws)
+[](https://github.com/websockets/ws/actions?query=workflow%3ACI+branch%3Amaster)
+[](https://ci.appveyor.com/project/lpinca/ws)
+[](https://coveralls.io/github/websockets/ws)
+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
+server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
+object. To make the same code work seamlessly on Node.js and the browser, you
+can use one of the many wrappers available on npm, like
+[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

+
+## Installing
+
+```
+npm install ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+ operations such as masking and unmasking the data payload of the WebSocket
+ frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
+ message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and
+utility functions.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which enables
+the client and server to negotiate a compression algorithm and its parameters,
+and then selectively apply it to the data payloads of each WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on the
+client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+Note that Node.js has a variety of issues with high-performance compression,
+where increased concurrency, especially on Linux, can lead to [catastrophic
+memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
+permessage-deflate in production, it is worthwhile to set up a test
+representative of your workload and ensure Node.js/zlib will handle it with
+acceptable performance and memory usage.
+
+Tuning of permessage-deflate can be done via the options defined below. You can
+also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
+into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
+
+See [the docs][ws-server-options] for more options.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+ port: 8080,
+ perMessageDeflate: {
+ zlibDeflateOptions: {
+ // See zlib defaults.
+ chunkSize: 1024,
+ memLevel: 7,
+ level: 3
+ },
+ zlibInflateOptions: {
+ chunkSize: 10 * 1024
+ },
+ // Other options settable:
+ clientNoContextTakeover: true, // Defaults to negotiated value.
+ serverNoContextTakeover: true, // Defaults to negotiated value.
+ serverMaxWindowBits: 10, // Defaults to negotiated value.
+ // Below options specified as default values.
+ concurrencyLimit: 10, // Limits zlib concurrency for perf.
+ threshold: 1024 // Size (in bytes) below which messages
+ // should not be compressed.
+ }
+});
+```
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+ perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ const array = new Float32Array(5);
+
+ for (var i = 0; i < array.length; ++i) {
+ array[i] = i / 2;
+ }
+
+ ws.send(array);
+});
+```
+
+### Simple server
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+const fs = require('fs');
+const https = require('https');
+const WebSocket = require('ws');
+
+const server = https.createServer({
+ cert: fs.readFileSync('/path/to/cert.pem'),
+ key: fs.readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+const url = require('url');
+
+const server = http.createServer();
+const wss1 = new WebSocket.Server({ noServer: true });
+const wss2 = new WebSocket.Server({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+ // ...
+});
+
+wss2.on('connection', function connection(ws) {
+ // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ const pathname = url.parse(request.url).pathname;
+
+ if (pathname === '/foo') {
+ wss1.handleUpgrade(request, socket, head, function done(ws) {
+ wss1.emit('connection', ws, request);
+ });
+ } else if (pathname === '/bar') {
+ wss2.handleUpgrade(request, socket, head, function done(ws) {
+ wss2.emit('connection', ws, request);
+ });
+ } else {
+ socket.destroy();
+ }
+});
+
+server.listen(8080);
+```
+
+### Client authentication
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+
+const server = http.createServer();
+const wss = new WebSocket.Server({ noServer: true });
+
+wss.on('connection', function connection(ws, request, client) {
+ ws.on('message', function message(msg) {
+ console.log(`Received message ${msg} from user ${client}`);
+ });
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ // This function is not defined on purpose. Implement it with your own logic.
+ authenticate(request, (err, client) => {
+ if (err || !client) {
+ socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
+ socket.destroy();
+ return;
+ }
+
+ wss.handleUpgrade(request, socket, head, function done(ws) {
+ wss.emit('connection', ws, request, client);
+ });
+ });
+});
+
+server.listen(8080);
+```
+
+Also see the provided [example][session-parse-example] using `express-session`.
+
+### Server broadcast
+
+A client WebSocket broadcasting to all connected WebSocket clients, including
+itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ wss.clients.forEach(function each(client) {
+ if (client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+A client WebSocket broadcasting to every other connected WebSocket clients,
+excluding itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ wss.clients.forEach(function each(client) {
+ if (client !== ws && client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+ console.log('connected');
+ ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+ console.log('disconnected');

+ console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+ setTimeout(function timeout() {
+ ws.send(Date.now());
+ }, 500);
+});
+```
+
+### Use the Node.js streams API
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+const duplex = WebSocket.createWebSocketStream(ws, { encoding: 'utf8' });
+
+duplex.pipe(process.stdout);
+process.stdin.pipe(duplex);
+```

+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+ const ip = req.socket.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+ const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a way
+that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+function noop() {}
+
+function heartbeat() {
+ this.isAlive = true;
+}
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.isAlive = true;
+ ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+ wss.clients.forEach(function each(ws) {
+ if (ws.isAlive === false) return ws.terminate();
+
+ ws.isAlive = false;
+ ws.ping(noop);
+ });
+}, 30000);
+
+wss.on('close', function close() {
+ clearInterval(interval);
+});
+```
+
+Pong messages are automatically sent in response to ping messages as required by
+the spec.
+
+Just like the server example above your clients might as well lose connection
+without knowing it. You might want to add a ping listener on your clients to
+prevent that. A simple implementation would be:
+
+```js
+const WebSocket = require('ws');
+
+function heartbeat() {
+ clearTimeout(this.pingTimeout);
+
+ // Use `WebSocket#terminate()`, which immediately destroys the connection,
+ // instead of `WebSocket#close()`, which waits for the close timer.
+ // Delay should be equal to the interval at which your server
+ // sends out pings plus a conservative assumption of the latency.
+ this.pingTimeout = setTimeout(() => {
+ this.terminate();
+ }, 30000 + 1000);
+}
+
+const client = new WebSocket('wss://echo.websocket.org/');
+
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+ clearTimeout(this.pingTimeout);
+});
+```
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

+# Engine.IO: the realtime engine
+
+[](https://github.com/socketio/engine.io/actions)
+[](http://badge.fury.io/js/engine.io)
+
+`Engine.IO` is the implementation of transport-based
+cross-browser/cross-device bi-directional communication layer for
+[Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Server
+
+#### (A) Listening on a port
+
+```js
+var engine = require('engine.io');
+var server = engine.listen(80);
+
+server.on('connection', function(socket){
+ socket.send('utf 8 string');
+ socket.send(Buffer.from([0, 1, 2, 3, 4, 5])); // binary data
+});
+```
+
+#### (B) Intercepting requests for a http.Server
+
+```js
+var engine = require('engine.io');
+var http = require('http').createServer().listen(3000);
+var server = engine.attach(http);
+
+server.on('connection', function (socket) {
+ socket.on('message', function(data){ });
+ socket.on('close', function(){ });
+});
+```
+
+#### (C) Passing in requests
+
+```js
+var engine = require('engine.io');
+var server = new engine.Server();
+
+server.on('connection', function(socket){
+ socket.send('hi');
+});
+
+// …
+httpServer.on('upgrade', function(req, socket, head){
+ server.handleUpgrade(req, socket, head);
+});
+httpServer.on('request', function(req, res){
+ server.handleRequest(req, res);
+});
+```
+
+### Client
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+ var socket = new eio.Socket('ws://localhost/');
+ socket.on('open', function(){
+ socket.on('message', function(data){});
+ socket.on('close', function(){});
+ });
+</script>
+```
+
+For more information on the client refer to the
+[engine-client](http://github.com/learnboost/engine.io-client) repository.
+
+## What features does it have?
+
+- **Maximum reliability**. Connections are established even in the presence of:
+ - proxies and load balancers.
+ - personal firewall and antivirus software.
+ - for more information refer to **Goals** and **Architecture** sections
+- **Minimal client size** aided by:
+ - lazy loading of flash transports.
+ - lack of redundant transports.
+- **Scalable**
+ - load balancer friendly
+- **Future proof**
+- **100% Node.JS core style**
+ - No API sugar (left for higher level projects)
+ - Written in readable vanilla JavaScript
+
+## API
+
+### Server
+
+<hr><br>
+
+#### Top-level
+
+These are exposed by `require('engine.io')`:
+
+##### Events
+
+- `flush`
+ - Called when a socket buffer is being flushed.
+ - **Arguments**
+ - `Socket`: socket being flushed
+ - `Array`: write buffer
+- `drain`
+ - Called when a socket buffer is drained
+ - **Arguments**
+ - `Socket`: socket being flushed
+
+##### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `Server`: Server class constructor
+- `Socket`: Socket class constructor
+- `Transport` _(Function)_: transport constructor
+- `transports` _(Object)_: map of available transports
+
+##### Methods
+
+- `()`
+ - Returns a new `Server` instance. If the first argument is an `http.Server` then the
+ new `Server` instance will be attached to it. Otherwise, the arguments are passed
+ directly to the `Server` constructor.
+ - **Parameters**
+ - `http.Server`: optional, server to attach to.
+ - `Object`: optional, options object (see `Server#constructor` api docs below)
+
+ The following are identical ways to instantiate a server and then attach it.
+
+```js
+var httpServer; // previously created with `http.createServer();` from node.js api.
+
+// create a server first, and then attach
+var eioServer = require('engine.io').Server();
+eioServer.attach(httpServer);
+
+// or call the module as a function to get `Server`
+var eioServer = require('engine.io')();
+eioServer.attach(httpServer);
+
+// immediately attach
+var eioServer = require('engine.io')(httpServer);
+
+// with custom options
+var eioServer = require('engine.io')(httpServer, {
+ maxHttpBufferSize: 1e3
+});
+```
+
+- `listen`
+ - Creates an `http.Server` which listens on the given port and attaches WS
+ to it. It returns `501 Not Implemented` for regular http requests.
+ - **Parameters**
+ - `Number`: port to listen on.
+ - `Object`: optional, options object
+ - `Function`: callback for `listen`.
+ - **Options**
+ - All options from `Server.attach` method, documented below.
+ - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+ - **Returns** `Server`
+
+```js
+var engine = require('engine.io');
+var server = engine.listen(3000, {
+ pingTimeout: 2000,
+ pingInterval: 10000
+});
+
+server.on('connection', /* ... */);
+```
+
+- `attach`
+ - Captures `upgrade` requests for a `http.Server`. In other words, makes
+ a regular http.Server WebSocket-compatible.
+ - **Parameters**
+ - `http.Server`: server to attach to.
+ - `Object`: optional, options object
+ - **Options**
+ - All options from `Server.attach` method, documented below.
+ - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+ - **Returns** `Server` a new Server instance.
+
+```js
+var engine = require('engine.io');
+var httpServer = require('http').createServer().listen(3000);
+var server = engine.attach(httpServer, {
+ wsEngine: 'uws' // requires having uws as dependency
+});
+
+server.on('connection', /* ... */);
+```
+
+#### Server
+
+The main server/manager. _Inherits from EventEmitter_.
+
+##### Events
+
+- `connection`
+ - Fired when a new connection is established.
+ - **Arguments**
+ - `Socket`: a Socket object
+
+##### Properties
+
+**Important**: if you plan to use Engine.IO in a scalable way, please
+keep in mind the properties below will only reflect the clients connected
+to a single process.
+
+- `clients` _(Object)_: hash of connected clients by id.
+- `clientsCount` _(Number)_: number of connected clients.
+
+##### Methods
+
+- **constructor**
+ - Initializes the server
+ - **Parameters**
+ - `Object`: optional, options object
+ - **Options**
+ - `pingTimeout` (`Number`): how many ms without a pong packet to
+ consider the connection closed (`5000`)
+ - `pingInterval` (`Number`): how many ms before sending a new ping
+ packet (`25000`)
+ - `upgradeTimeout` (`Number`): how many ms before an uncompleted transport upgrade is cancelled (`10000`)
+ - `maxHttpBufferSize` (`Number`): how many bytes or characters a message
+ can be, before closing the session (to avoid DoS). Default
+ value is `10E7`.
+ - `allowRequest` (`Function`): A function that receives a given handshake
+ or upgrade request as its first parameter, and can decide whether to
+ continue or not. The second argument is a function that needs to be
+ called with the decided information: `fn(err, success)`, where
+ `success` is a boolean value where false means that the request is
+ rejected, and err is an error code.
+ - `transports` (`<Array> String`): transports to allow connections
+ to (`['polling', 'websocket']`)
+ - `allowUpgrades` (`Boolean`): whether to allow transport upgrades
+ (`true`)
+ - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+ (see [ws module](https://github.com/einaros/ws) api docs). Set to `true` to enable. (`false`)
+ - `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
+ - `httpCompression` (`Object|Boolean`): parameters of the http compression for the polling transports

+ - `cookie` (`String|Boolean`): name of the HTTP cookie that
+ contains the client sid to send as part of handshake response
+ headers. Set to `false` to not send one. (`io`)
+ - `cookiePath` (`String|Boolean`): path of the above `cookie`
+ option. If false, no path will be sent, which means browsers will only send the cookie on the engine.io attached path (`/engine.io`).
+ Set false to not save io cookie on all requests. (`/`)
+ - `cookieHttpOnly` (`Boolean`): If `true` HttpOnly io cookie cannot be accessed by client-side APIs, such as JavaScript. (`true`) _This option has no effect if `cookie` or `cookiePath` is set to `false`._
+ - `wsEngine` (`String`): what WebSocket server implementation to use. Specified module must conform to the `ws` interface (see [ws module api docs](https://github.com/websockets/ws/blob/master/doc/ws.md)). Default value is `ws`. An alternative c++ addon is also available by installing `uws` module.

+### Client
+
+<hr><br>
+
+Exposed in the `eio` global namespace (in the browser), or by
+`require('engine.io-client')` (in Node.JS).
+
+For the client API refer to the
+[engine-client](http://github.com/learnboost/engine.io-client) repository.
+
+## Debug / logging
+
+Engine.IO is powered by [debug](http://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Engine.IO's debugging scopes you can use:
+
+```
+DEBUG=engine* node myapp
+```
+
+## Transports
+
+- `polling`: XHR / JSONP polling transport.
+- `websocket`: WebSocket transport.
+
+## Plugins
+
+- [engine.io-conflation](https://github.com/EugenDueck/engine.io-conflation): Makes **conflation and aggregation** of messages straightforward.
+
+## Support
+
+The support channels for `engine.io` are the same as `socket.io`:
+ - irc.freenode.net **#socket.io**
+ - [Google Groups](http://groups.google.com/group/socket_io)
+ - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```
+git clone git://github.com/LearnBoost/engine.io.git
+```
+
+Then:
+
+```
+cd engine.io
+npm install
+```
+
+## Tests
+
+Tests run with `npm test`. It runs the server tests that are aided by
+the usage of `engine.io-client`.
+
+Make sure `npm install` is run first.
+
+## Goals
+
+The main goal of `Engine` is ensuring the most reliable realtime communication.
+Unlike the previous Socket.IO core, it always establishes a long-polling
+connection first, then tries to upgrade to better transports that are "tested" on
+the side.
+
+During the lifetime of the Socket.IO projects, we've found countless drawbacks
+to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
+mechanisms.
+
+Both are clearly the _right way_ of establishing a bidirectional communication,
+with HTML5 WebSocket being the way of the future. However, to answer most business
+needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
+the same solution.
+
+WebSocket based connections have two fundamental benefits:
+
+1. **Better server performance**
+ - _A: Load balancers_<br>
+ Load balancing a long polling connection poses a serious architectural nightmare
+ since requests can come from any number of open sockets by the user agent, but
+ they all need to be routed to the process and computer that owns the `Engine`
+ connection. This negatively impacts RAM and CPU usage.
+ - _B: Network traffic_<br>
+ WebSocket is designed around the premise that each message frame has to be
+ surrounded by the least amount of data. In HTTP 1.1 transports, each message
+ frame is surrounded by HTTP headers and chunked encoding frames. If you try to
+ send the message _"Hello world"_ with xhr-polling, the message ultimately
+ becomes larger than if you were to send it with WebSocket.
+ - _C: Lightweight parser_<br>
+ As an effect of **B**, the server has to do a lot more work to parse the network
+ data and figure out the message when traditional HTTP requests are used
+ (as in long polling). This means that another advantage of WebSocket is
+ less server CPU usage.
+
+2. **Better user experience**
+
+ Due to the reasons stated in point **1**, the most important effect of being able
+ to establish a WebSocket connection is raw data transfer speed, which translates
+ in _some_ cases in better user experience.
+
+ Applications with heavy realtime interaction (such as games) will benefit greatly,
+ whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
+ timelines (Twitter) will have negligible user experience improvements.
+
+Having said this, attempting to establish a WebSocket connection directly so far has
+proven problematic:
+
+1. **Proxies**<br>
+ Many corporate proxies block WebSocket traffic.
+
+2. **Personal firewall and antivirus software**<br>
+ As a result of our research, we've found that at least 3 personal security
+ applications block WebSocket traffic.
+
+3. **Cloud application platforms**<br>
+ Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
+ nature of the evolution of the WebSocket protocol. Applications therefore end up
+ inevitably using long polling, but the seamless installation experience of
+ Socket.IO we strive for (_"require() it and it just works"_) disappears.
+
+Some of these problems have solutions. In the case of proxies and personal programs,
+however, the solutions many times involve upgrading software. Experience has shown
+that relying on client software upgrades to deliver a business solution is
+fruitless: the very existence of this project has to do with a fragmented panorama
+of user agent distribution, with clients connecting with latest versions of the most
+modern user agents (Chrome, Firefox and Safari), but others with versions as low as
+IE 5.5.
+
+From the user perspective, an unsuccessful WebSocket connection can translate in
+up to at least 10 seconds of waiting for the realtime application to begin
+exchanging data. This **perceptively** hurts user experience.
+
+To summarize, **Engine** focuses on reliability and user experience first, marginal
+potential UX improvements and increased server performance second. `Engine` is the
+result of all the lessons learned with WebSocket in the wild.
+
+## Architecture
+
+The main premise of `Engine`, and the core of its existence, is the ability to
+swap transports on the fly. A connection starts as xhr-polling, but it can
+switch to WebSocket.
+
+The central problem this poses is: how do we switch transports without losing
+messages?
+
+`Engine` only switches from polling to another transport in between polling
+cycles. Since the server closes the connection after a certain timeout when
+there's no activity, and the polling transport implementation buffers messages
+in between connections, this ensures no message loss and optimal performance.
+
+Another benefit of this design is that we workaround almost all the limitations
+of **Flash Socket**, such as slow connection times, increased file size (we can
+safely lazy load it without hurting user experience), etc.
+
+## FAQ
+
+### Can I use engine without Socket.IO ?
+
+Absolutely. Although the recommended framework for building realtime applications
+is Socket.IO, since it provides fundamental features for real-world applications
+such as multiplexing, reconnection support, etc.
+
+`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
+realtime frameworks, but something you _probably_ won't be using for building
+actual applications.
+
+### Does the server serve the client?
+
+No. The main reason is that `Engine` is meant to be bundled with frameworks.
+Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
+you use Socket.IO, including
+
+```html
+<script src="/socket.io/socket.io.js">
+```
+
+has you covered.
+
+### Can I implement `Engine` in other languages?
+
+Absolutely. The [engine.io-protocol](https://github.com/LearnBoost/engine.io-protocol)
+repository contains the most up to date description of the specification
+at all times, and the parser implementation in JavaScript.

+
+Basic HTTP cookie parser and serializer for HTTP servers.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install cookie
+```
+
+## API
+
+```js
+var cookie = require('cookie');
+```
+
+### cookie.parse(str, options)
+
+Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
+The `str` argument is the string representing a `Cookie` header value and `options` is an
+optional object containing additional parsing options.
+
+```js
+var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
+// { foo: 'bar', equation: 'E=mc^2' }
+```
+
+#### Options
+
+`cookie.parse` accepts these properties in the options object.
+
+##### decode
+
+Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
+has a limited character set (and must be a simple string), this function can be used to decode
+a previously-encoded cookie value into a JavaScript string or other object.
+
+The default function is the global `decodeURIComponent`, which will decode any URL-encoded
+sequences into their byte representations.
+
+**note** if an error is thrown from this function, the original, non-decoded cookie value will
+be returned as the cookie's value.
+
+### cookie.serialize(name, value, options)
+
+Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
+name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
+argument is an optional object containing additional serialization options.
+
+```js
+var setCookie = cookie.serialize('foo', 'bar');
+// foo=bar
+```
+
+#### Options
+
+`cookie.serialize` accepts these properties in the options object.
+
+##### domain
+
+Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6265-5.2.3]. By default, no
+domain is set, and most clients will consider the cookie to apply to only the current domain.
+
+##### encode
+
+Specifies a function that will be used to encode a cookie's value. Since value of a cookie
+has a limited character set (and must be a simple string), this function can be used to encode
+a value into a string suited for a cookie's value.
+
+The default function is the global `encodeURIComponent`, which will encode a JavaScript string
+into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
+
+##### expires
+
+Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6265-5.2.1].
+By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
+will delete it on a condition like exiting a web browser application.
+
+**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
+`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### httpOnly
+
+Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6265-5.2.6]. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not allow client-side
+JavaScript to see the cookie in `document.cookie`.
+
+##### maxAge
+
+Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6265-5.2.2].
+The given number will be converted to an integer by rounding down. By default, no maximum age is set.
+
+**note** the [cookie storage model specification][rfc-6265-5.3] states that if both `expires` and
+`maxAge` are set, then `maxAge` takes precedence, but it is possible not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### path
+
+Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6265-5.2.4]. By default, the path
+is considered the ["default path"][rfc-6265-5.1.4].
+
+##### sameSite
+
+Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][rfc-6265bis-03-4.1.2.7].
+
+ - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+ - `false` will not set the `SameSite` attribute.
+ - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+ - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
+ - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in
+[the specification][rfc-6265bis-03-4.1.2.7].
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### secure
+
+Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6265-5.2.5]. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
+the server in the future if the browser does not have an HTTPS connection.
+
+## Example
+
+The following example uses this module in conjunction with the Node.js core HTTP server
+to prompt a user for their name and display it back on future visits.
+
+```js
+var cookie = require('cookie');
+var escapeHtml = require('escape-html');
+var http = require('http');
+var url = require('url');
+
+function onRequest(req, res) {
+ // Parse the query string
+ var query = url.parse(req.url, true, true).query;
+
+ if (query && query.name) {
+ // Set a new cookie with the name
+ res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
+ httpOnly: true,
+ maxAge: 60 * 60 * 24 * 7 // 1 week
+ }));
+
+ // Redirect back after setting cookie
+ res.statusCode = 302;
+ res.setHeader('Location', req.headers.referer || '/');
+ res.end();
+ return;
+ }
+
+ // Parse the cookies on the request
+ var cookies = cookie.parse(req.headers.cookie || '');
+
+ // Get the visitor name set in the cookie
+ var name = cookies.name;
+
+ res.setHeader('Content-Type', 'text/html; charset=UTF-8');
+
+ if (name) {
+ res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
+ } else {
+ res.write('<p>Hello, new visitor!</p>');
+ }
+
+ res.write('<form method="GET">');
+ res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
+ res.end('</form>');
+}
+
+http.createServer(onRequest).listen(3000);
+```

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:

+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).

+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+
+[](https://www.npmjs.com/package/ws)
+[](https://github.com/websockets/ws/actions?query=workflow%3ACI+branch%3Amaster)
+[](https://ci.appveyor.com/project/lpinca/ws)
+[](https://coveralls.io/github/websockets/ws)
+
+ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
+server implementation.
+
+Passes the quite extensive Autobahn test suite: [server][server-report],
+[client][client-report].
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
+object. To make the same code work seamlessly on Node.js and the browser, you
+can use one of the many wrappers available on npm, like
+[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

+There are 2 optional modules that can be installed along side with the ws
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+ operations such as masking and unmasking the data payload of the WebSocket
+ frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
+ message contains valid UTF-8 as required by the spec.
+
+## API docs
+
+See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and
+utility functions.
+
+## WebSocket compression
+
+ws supports the [permessage-deflate extension][permessage-deflate] which enables
+the client and server to negotiate a compression algorithm and its parameters,
+and then selectively apply it to the data payloads of each WebSocket message.
+
+The extension is disabled by default on the server and enabled by default on the
+client. It adds a significant overhead in terms of performance and memory
+consumption so we suggest to enable it only if it is really needed.
+
+Note that Node.js has a variety of issues with high-performance compression,
+where increased concurrency, especially on Linux, can lead to [catastrophic
+memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
+permessage-deflate in production, it is worthwhile to set up a test
+representative of your workload and ensure Node.js/zlib will handle it with
+acceptable performance and memory usage.
+
+Tuning of permessage-deflate can be done via the options defined below. You can
+also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
+into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
+
+See [the docs][ws-server-options] for more options.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+ port: 8080,
+ perMessageDeflate: {
+ zlibDeflateOptions: {
+ // See zlib defaults.
+ chunkSize: 1024,
+ memLevel: 7,
+ level: 3
+ },
+ zlibInflateOptions: {
+ chunkSize: 10 * 1024
+ },
+ // Other options settable:
+ clientNoContextTakeover: true, // Defaults to negotiated value.
+ serverNoContextTakeover: true, // Defaults to negotiated value.
+ serverMaxWindowBits: 10, // Defaults to negotiated value.
+ // Below options specified as default values.
+ concurrencyLimit: 10, // Limits zlib concurrency for perf.
+ threshold: 1024 // Size (in bytes) below which messages
+ // should not be compressed.
+ }
+});
+```
+
+The client will only use the extension if it is supported and enabled on the
+server. To always disable the extension on the client set the
+`perMessageDeflate` option to `false`.
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+ perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ ws.send('something');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(data);
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+ const array = new Float32Array(5);
+
+ for (var i = 0; i < array.length; ++i) {
+ array[i] = i / 2;
+ }
+
+ ws.send(array);
+});
+```
+
+### Simple server
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+```
+
+### External HTTP/S server
+
+```js
+const fs = require('fs');
+const https = require('https');
+const WebSocket = require('ws');
+
+const server = https.createServer({
+ cert: fs.readFileSync('/path/to/cert.pem'),
+ key: fs.readFileSync('/path/to/key.pem')
+});
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(message) {
+ console.log('received: %s', message);
+ });
+
+ ws.send('something');
+});
+
+server.listen(8080);
+```
+
+### Multiple servers sharing a single HTTP/S server
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+const url = require('url');
+
+const server = http.createServer();
+const wss1 = new WebSocket.Server({ noServer: true });
+const wss2 = new WebSocket.Server({ noServer: true });
+
+wss1.on('connection', function connection(ws) {
+ // ...
+});
+
+wss2.on('connection', function connection(ws) {
+ // ...
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ const pathname = url.parse(request.url).pathname;
+
+ if (pathname === '/foo') {
+ wss1.handleUpgrade(request, socket, head, function done(ws) {
+ wss1.emit('connection', ws, request);
+ });
+ } else if (pathname === '/bar') {
+ wss2.handleUpgrade(request, socket, head, function done(ws) {
+ wss2.emit('connection', ws, request);
+ });
+ } else {
+ socket.destroy();
+ }
+});
+
+server.listen(8080);
+```
+
+### Client authentication
+
+```js
+const http = require('http');
+const WebSocket = require('ws');
+
+const server = http.createServer();
+const wss = new WebSocket.Server({ noServer: true });
+
+wss.on('connection', function connection(ws, request, client) {
+ ws.on('message', function message(msg) {
+ console.log(`Received message ${msg} from user ${client}`);
+ });
+});
+
+server.on('upgrade', function upgrade(request, socket, head) {
+ // This function is not defined on purpose. Implement it with your own logic.
+ authenticate(request, (err, client) => {
+ if (err || !client) {
+ socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
+ socket.destroy();
+ return;
+ }
+
+ wss.handleUpgrade(request, socket, head, function done(ws) {
+ wss.emit('connection', ws, request, client);
+ });
+ });
+});
+
+server.listen(8080);
+```
+
+Also see the provided [example][session-parse-example] using `express-session`.
+
+### Server broadcast
+
+A client WebSocket broadcasting to all connected WebSocket clients, including
+itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ wss.clients.forEach(function each(client) {
+ if (client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+A client WebSocket broadcasting to every other connected WebSocket clients,
+excluding itself.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.on('message', function incoming(data) {
+ wss.clients.forEach(function each(client) {
+ if (client !== ws && client.readyState === WebSocket.OPEN) {
+ client.send(data);
+ }
+ });
+ });
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+ console.log('connected');
+ ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+ console.log('disconnected');
+});
+
+ws.on('message', function incoming(data) {
+ console.log(`Roundtrip time: ${Date.now() - data} ms`);
+
+ setTimeout(function timeout() {
+ ws.send(Date.now());
+ }, 500);
+});
+```
+
+### Use the Node.js streams API
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+ origin: 'https://websocket.org'
+});
+
+const duplex = WebSocket.createWebSocketStream(ws, { encoding: 'utf8' });
+
+duplex.pipe(process.stdout);
+process.stdin.pipe(duplex);
+```
+

+examples folder.
+
+Otherwise, see the test cases.
+
+## FAQ
+
+### How to get the IP address of the client?
+
+The remote IP address can be obtained from the raw socket.
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws, req) {
+ const ip = req.socket.remoteAddress;
+});
+```
+
+When the server runs behind a proxy like NGINX, the de-facto standard is to use
+the `X-Forwarded-For` header.
+
+```js
+wss.on('connection', function connection(ws, req) {
+ const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
+});
+```
+
+### How to detect and close broken connections?
+
+Sometimes the link between the server and the client can be interrupted in a way
+that keeps both the server and the client unaware of the broken state of the
+connection (e.g. when pulling the cord).
+
+In these cases ping messages can be used as a means to verify that the remote
+endpoint is still responsive.
+
+```js
+const WebSocket = require('ws');
+
+function noop() {}
+
+function heartbeat() {
+ this.isAlive = true;
+}
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+ ws.isAlive = true;
+ ws.on('pong', heartbeat);
+});
+
+const interval = setInterval(function ping() {
+ wss.clients.forEach(function each(ws) {
+ if (ws.isAlive === false) return ws.terminate();
+
+ ws.isAlive = false;
+ ws.ping(noop);
+ });
+}, 30000);
+
+wss.on('close', function close() {
+ clearInterval(interval);
+});
+```
+
+Pong messages are automatically sent in response to ping messages as required by
+the spec.
+
+Just like the server example above your clients might as well lose connection
+without knowing it. You might want to add a ping listener on your clients to
+prevent that. A simple implementation would be:
+
+```js
+const WebSocket = require('ws');
+
+function heartbeat() {
+ clearTimeout(this.pingTimeout);
+
+ // Use `WebSocket#terminate()`, which immediately destroys the connection,
+ // instead of `WebSocket#close()`, which waits for the close timer.
+ // Delay should be equal to the interval at which your server
+ // sends out pings plus a conservative assumption of the latency.
+ this.pingTimeout = setTimeout(() => {
+ this.terminate();
+ }, 30000 + 1000);
+}
+
+const client = new WebSocket('wss://echo.websocket.org/');
+
+client.on('open', heartbeat);
+client.on('ping', heartbeat);
+client.on('close', function clear() {
+ clearTimeout(this.pingTimeout);
+});
+```
+
+### How to connect via a proxy?
+
+Use a custom `http.Agent` implementation like [https-proxy-agent][] or
+[socks-proxy-agent][].

-
-Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
-Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
-
-In addition to negotiator, it allows:
-
-- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
- as well as `('text/html', 'application/json')`.
-- Allows type shorthands such as `json`.
-- Returns `false` when no types match
-- Treats non-existent headers as `*`
-
-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install accepts
-```
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var accepts = require('accepts')
-```
-
-### accepts(req)
-
-Create a new `Accepts` object for the given `req`.
-
-#### .charset(charsets)
-
-Return the first accepted charset. If nothing in `charsets` is accepted,
-then `false` is returned.
-
-#### .charsets()
-
-Return the charsets that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .encoding(encodings)
-
-Return the first accepted encoding. If nothing in `encodings` is accepted,
-then `false` is returned.
-
-#### .encodings()
-
-Return the encodings that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .language(languages)
-
-Return the first accepted language. If nothing in `languages` is accepted,
-then `false` is returned.
-
-#### .languages()
-
-Return the languages that the request accepts, in the order of the client's
-preference (most preferred first).
-
-#### .type(types)
-
-Return the first accepted type (and it is returned as the same text as what
-appears in the `types` array). If nothing in `types` is accepted, then `false`
-is returned.
-
-The `types` array can contain full MIME types or file extensions. Any value
-that is not a full MIME types is passed to `require('mime-types').lookup`.
-
-#### .types()
-
-Return the types that the request accepts, in the order of the client's
-preference (most preferred first).
-
-## Examples
-
-### Simple type negotiation
-
-This simple example shows how to use `accepts` to return a different typed
-respond body based on what the client wants to accept. The server lists it's
-preferences in order and will get back the best match between the client and
-server.
-
-```js
-var accepts = require('accepts')
-var http = require('http')
-
-function app (req, res) {
- var accept = accepts(req)
-
- // the order of this list is significant; should be server preferred order
- switch (accept.type(['json', 'html'])) {
- case 'json':
- res.setHeader('Content-Type', 'application/json')
- res.write('{"hello":"world!"}')
- break
- case 'html':
- res.setHeader('Content-Type', 'text/html')
- res.write('<b>hello, world!</b>')
- break
- default:
- // the fallback is text/plain, so no need to specify it above
- res.setHeader('Content-Type', 'text/plain')
- res.write('hello, world!')
- break
- }
-
- res.end()
-}
-
-http.createServer(app).listen(3000)
-```
-
-You can test this out with the cURL program:
-```sh
-curl -I -H'Accept: text/html' http://localhost:3000/
-```

-## 2.0.6
-
-Version 2.0.4 adds support for React Native by clarifying in package.json that
-the browser environment does not support Node.js domains.
-Why this is necessary, we leave as an exercise for the user.
-
-## 2.0.3
-
-Version 2.0.3 fixes a bug when adjusting the capacity of the task queue.
-
-## 2.0.1-2.02
-
-Version 2.0.1 fixes a bug in the way redirects were expressed that affected the
-function of Browserify, but which Mr would tolerate.
-
-## 2.0.0
-
-Version 2 of ASAP is a full rewrite with a few salient changes.
-First, the ASAP source is CommonJS only and designed with [Browserify][] and
-[Browserify-compatible][Mr] module loaders in mind.
-
-[Browserify]: https://github.com/substack/node-browserify
-[Mr]: https://github.com/montagejs/mr
-
-The new version has been refactored in two dimensions.
-Support for Node.js and browsers have been separated, using Browserify
-redirects and ASAP has been divided into two modules.
-The "raw" layer depends on the tasks to catch thrown exceptions and unravel
-Node.js domains.
-
-The full implementation of ASAP is loadable as `require("asap")` in both Node.js
-and browsers.
-
-The raw layer that lacks exception handling overhead is loadable as
-`require("asap/raw")`.
-The interface is the same for both layers.
-
-Tasks are no longer required to be functions, but can rather be any object that
-implements `task.call()`.
-With this feature you can recycle task objects to avoid garbage collector churn
-and avoid closures in general.
-
-The implementation has been rigorously documented so that our successors can
-understand the scope of the problem that this module solves and all of its
-nuances, ensuring that the next generation of implementations know what details
-are essential.

-# ASAP
-
-[](https://travis-ci.org/kriskowal/asap)
-
-Promise and asynchronous observer libraries, as well as hand-rolled callback
-programs and libraries, often need a mechanism to postpone the execution of a
-callback until the next available event.
-(See [Designing API’s for Asynchrony][Zalgo].)
-The `asap` function executes a task **as soon as possible** but not before it
-returns, waiting only for the completion of the current event and previously
-scheduled tasks.
-
-```javascript
-asap(function () {
- // ...
-});
-```
-
-[Zalgo]: http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony
-
-This CommonJS package provides an `asap` module that exports a function that
-executes a task function *as soon as possible*.
-
-ASAP strives to schedule events to occur before yielding for IO, reflow,
-or redrawing.
-Each event receives an independent stack, with only platform code in parent
-frames and the events run in the order they are scheduled.
-
-ASAP provides a fast event queue that will execute tasks until it is
-empty before yielding to the JavaScript engine's underlying event-loop.
-When a task gets added to a previously empty event queue, ASAP schedules a flush
-event, preferring for that event to occur before the JavaScript engine has an
-opportunity to perform IO tasks or rendering, thus making the first task and
-subsequent tasks semantically indistinguishable.
-ASAP uses a variety of techniques to preserve this invariant on different
-versions of browsers and Node.js.
-
-By design, ASAP prevents input events from being handled until the task
-queue is empty.
-If the process is busy enough, this may cause incoming connection requests to be
-dropped, and may cause existing connections to inform the sender to reduce the
-transmission rate or stall.
-ASAP allows this on the theory that, if there is enough work to do, there is no
-sense in looking for trouble.
-As a consequence, ASAP can interfere with smooth animation.
-If your task should be tied to the rendering loop, consider using
-`requestAnimationFrame` instead.
-A long sequence of tasks can also effect the long running script dialog.
-If this is a problem, you may be able to use ASAP’s cousin `setImmediate` to
-break long processes into shorter intervals and periodically allow the browser
-to breathe.
-`setImmediate` will yield for IO, reflow, and repaint events.
-It also returns a handler and can be canceled.
-For a `setImmediate` shim, consider [YuzuJS setImmediate][setImmediate].
-
-[setImmediate]: https://github.com/YuzuJS/setImmediate
-
-Take care.
-ASAP can sustain infinite recursive calls without warning.
-It will not halt from a stack overflow, and it will not consume unbounded
-memory.
-This is behaviorally equivalent to an infinite loop.
-Just as with infinite loops, you can monitor a Node.js process for this behavior
-with a heart-beat signal.
-As with infinite loops, a very small amount of caution goes a long way to
-avoiding problems.
-
-```javascript
-function loop() {
- asap(loop);
-}
-loop();
-```
-
-In browsers, if a task throws an exception, it will not interrupt the flushing
-of high-priority tasks.
-The exception will be postponed to a later, low-priority event to avoid
-slow-downs.
-In Node.js, if a task throws an exception, ASAP will resume flushing only if—and
-only after—the error is handled by `domain.on("error")` or
-`process.on("uncaughtException")`.
-
-## Raw ASAP
-
-Checking for exceptions comes at a cost.
-The package also provides an `asap/raw` module that exports the underlying
-implementation which is faster but stalls if a task throws an exception.
-This internal version of the ASAP function does not check for errors.
-If a task does throw an error, it will stall the event queue unless you manually
-call `rawAsap.requestFlush()` before throwing the error, or any time after.
-
-In Node.js, `asap/raw` also runs all tasks outside any domain.
-If you need a task to be bound to your domain, you will have to do it manually.
-
-```js
-if (process.domain) {
- task = process.domain.bind(task);
-}
-rawAsap(task);
-```
-
-## Tasks
-
-A task may be any object that implements `call()`.
-A function will suffice, but closures tend not to be reusable and can cause
-garbage collector churn.
-Both `asap` and `rawAsap` accept task objects to give you the option of
-recycling task objects or using higher callable object abstractions.
-See the `asap` source for an illustration.
-
-
-## Compatibility
-
-ASAP is tested on Node.js v0.10 and in a broad spectrum of web browsers.
-The following charts capture the browser test results for the most recent
-release.
-The first chart shows test results for ASAP running in the main window context.
-The second chart shows test results for ASAP running in a web worker context.
-Test results are inconclusive (grey) on browsers that do not support web
-workers.
-These data are captured automatically by [Continuous
-Integration][].

-
-
-## Caveats
-
-When a task is added to an empty event queue, it is not always possible to
-guarantee that the task queue will begin flushing immediately after the current
-event.
-However, once the task queue begins flushing, it will not yield until the queue
-is empty, even if the queue grows while executing tasks.
-
-The following browsers allow the use of [DOM mutation observers][] to access
-the HTML [microtask queue][], and thus begin flushing ASAP's task queue
-immediately at the end of the current event loop turn, before any rendering or
-IO:
-
-[microtask queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#microtask-queue
-[DOM mutation observers]: http://dom.spec.whatwg.org/#mutation-observers
-
-- Android 4–4.3
-- Chrome 26–34
-- Firefox 14–29
-- Internet Explorer 11
-- iPad Safari 6–7.1
-- iPhone Safari 7–7.1
-- Safari 6–7
-
-In the absense of mutation observers, there are a few browsers, and situations
-like web workers in some of the above browsers, where [message channels][]
-would be a useful way to avoid falling back to timers.
-Message channels give direct access to the HTML [task queue][], so the ASAP
-task queue would flush after any already queued rendering and IO tasks, but
-without having the minimum delay imposed by timers.
-However, among these browsers, Internet Explorer 10 and Safari do not reliably
-dispatch messages, so they are not worth the trouble to implement.
-
-[message channels]: http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#message-channels
-[task queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#concept-task
-
-- Internet Explorer 10
-- Safair 5.0-1
-- Opera 11-12
-
-In the absense of mutation observers, these browsers and the following browsers
-all fall back to using `setTimeout` and `setInterval` to ensure that a `flush`
-occurs.
-The implementation uses both and cancels whatever handler loses the race, since
-`setTimeout` tends to occasionally skip tasks in unisolated circumstances.
-Timers generally delay the flushing of ASAP's task queue for four milliseconds.
-
-- Firefox 3–13
-- Internet Explorer 6–10
-- iPad Safari 4.3
-- Lynx 2.8.7
-
-
-## Heritage
-
-ASAP has been factored out of the [Q][] asynchronous promise library.
-It originally had a naïve implementation in terms of `setTimeout`, but
-[Malte Ubl][NonBlocking] provided an insight that `postMessage` might be
-useful for creating a high-priority, no-delay event dispatch hack.
-Since then, Internet Explorer proposed and implemented `setImmediate`.
-Robert Katić began contributing to Q by measuring the performance of
-the internal implementation of `asap`, paying particular attention to
-error recovery.
-Domenic, Robert, and Kris Kowal collectively settled on the current strategy of
-unrolling the high-priority event queue internally regardless of what strategy
-we used to dispatch the potentially lower-priority flush event.
-Domenic went on to make ASAP cooperate with Node.js domains.
-
-[Q]: https://github.com/kriskowal/q
-[NonBlocking]: http://www.nonblocking.io/2011/06/windownexttick.html
-
-For further reading, Nicholas Zakas provided a thorough article on [The
-Case for setImmediate][NCZ].
-
-[NCZ]: http://www.nczonline.net/blog/2013/07/09/the-case-for-setimmediate/
-
-Ember’s RSVP promise implementation later [adopted][RSVP ASAP] the name ASAP but
-further developed the implentation.
-Particularly, The `MessagePort` implementation was abandoned due to interaction
-[problems with Mobile Internet Explorer][IE Problems] in favor of an
-implementation backed on the newer and more reliable DOM `MutationObserver`
-interface.
-These changes were back-ported into this library.
-
-[IE Problems]: https://github.com/cujojs/when/issues/197
-[RSVP ASAP]: https://github.com/tildeio/rsvp.js/blob/cddf7232546a9cf858524b75cde6f9edf72620a7/lib/rsvp/asap.js
-
-In addition, ASAP factored into `asap` and `asap/raw`, such that `asap` remained
-exception-safe, but `asap/raw` provided a tight kernel that could be used for
-tasks that guaranteed that they would not throw exceptions.
-This core is useful for promise implementations that capture thrown errors in
-rejected promises and do not need a second safety net.
-At the same time, the exception handling in `asap` was factored into separate
-implementations for Node.js and browsers, using the the [Browserify][Browser
-Config] `browser` property in `package.json` to instruct browser module loaders
-and bundlers, including [Browserify][], [Mr][], and [Mop][], to use the
-browser-only implementation.

-// is to add a scroll event listener that calls for a flush.
-
-// `setTimeout` does not call the passed callback if the delay is less than
-// approximately 7 in web workers in Firefox 8 through 18, and sometimes not
-// even then.

- // between events.
- var timeoutHandle = setTimeout(handleTimer, 0);
- // However, since this timer gets frequently dropped in Firefox
- // workers, we enlist an interval handle that will try to fire
- // an event 20 times per second until it succeeds.

-deep-is
-==========
-
-Node's `assert.deepEqual() algorithm` as a standalone module. Exactly like
-[deep-equal](https://github.com/substack/node-deep-equal) except for the fact that `deepEqual(NaN, NaN) === true`.
-
-This module is around [5 times faster](https://gist.github.com/2790507)
-than wrapping `assert.deepEqual()` in a `try/catch`.
-
-[](http://ci.testling.com/thlorenz/deep-is)
-
-[](http://travis-ci.org/thlorenz/deep-is)
-
-example
-=======
-
-``` js
-var equal = require('deep-is');
-console.dir([
- equal(
- { a : [ 2, 3 ], b : [ 4 ] },
- { a : [ 2, 3 ], b : [ 4 ] }
- ),
- equal(
- { x : 5, y : [6] },
- { x : 5, y : 6 }
- )
-]);
-```
-
-methods
-=======
-
-var deepIs = require('deep-is')
-
-deepIs(a, b)
----------------
-
-Compare objects `a` and `b`, returning whether they are equal according to a
-recursive equality algorithm.
-
-install
-=======
-
-With [npm](http://npmjs.org) do:
-
-```
-npm install deep-is
-```
-
-test
-====
-
-With [npm](http://npmjs.org) do:

-# fast-levenshtein - Levenshtein algorithm in Javascript
-
-[](http://travis-ci.org/hiddentao/fast-levenshtein)
-
-An efficient Javascript implementation of the [Levenshtein algorithm](http://en.wikipedia.org/wiki/Levenshtein_distance) with asynchronous callback support.
-
-## Features
-
-* Works in node.js and in the browser.
-* Better performance than other implementations by not needing to store the whole matrix ([more info](http://www.codeproject.com/Articles/13525/Fast-memory-efficient-Levenshtein-algorithm)).
-* Provides synchronous and asynchronous versions of the algorithm.
-* Asynchronous version is almost as fast as the synchronous version for small strings and can also provide progress updates.
-* Comprehensive test suite and performance benchmark.
-* Small: <1 KB minified and gzipped
-
-## Installation
-
-### node.js
-
-Install using [npm](http://npmjs.org/):
-
-```bash
-$ npm install fast-levenshtein
-```
-
-### Browser
-
-Using bower:
-
-```bash
-$ bower install fast-levenshtein
-```
-
-If you are not using any module loader system then the API will then be accessible via the `window.Levenshtein` object.
-
-## Examples
-
-**Synchronous**
-
-```javascript
-var levenshtein = require('fast-levenshtein');
-
-var distance = levenshtein.get('back', 'book'); // 2
-var distance = levenshtein.get('我愛你', '我叫你'); // 1
-```
-
-**Asynchronous**
-
-```javascript
-var levenshtein = require('fast-levenshtein');
-
-levenshtein.getAsync('back', 'book', function (err, distance) {
- // err is null unless an error was thrown
- // distance equals 2
-});
-```
-
-**Asynchronous with progress updates**
-
-```javascript
-var levenshtein = require('fast-levenshtein');
-
-var hugeText1 = fs.readFileSync(...);
-var hugeText2 = fs.readFileSync(...);
-
-levenshtein.getAsync(hugeText1, hugeText2, function (err, distance) {
- // process the results as normal
-}, {
- progress: function(percentComplete) {
- console.log(percentComplete + ' % completed so far...');
- }
-);
-```
-
-## Building and Testing
-
-To build the code and run the tests:
-
-```bash
-$ npm install -g grunt-cli
-$ npm install
-$ npm run build
-```
-
-## Performance
-
-_Thanks to [Titus Wormer](https://github.com/wooorm) for [encouraging me](https://github.com/hiddentao/fast-levenshtein/issues/1) to do this._
-
-Benchmarked against other node.js levenshtein distance modules (on Macbook Air 2012, Core i7, 8GB RAM):
-
-```bash
-Running suite Implementation comparison [benchmark/speed.js]...
->> levenshtein-edit-distance x 234 ops/sec ±3.02% (73 runs sampled)
->> levenshtein-component x 422 ops/sec ±4.38% (83 runs sampled)
->> levenshtein-deltas x 283 ops/sec ±3.83% (78 runs sampled)
->> natural x 255 ops/sec ±0.76% (88 runs sampled)
->> levenshtein x 180 ops/sec ±3.55% (86 runs sampled)
->> fast-levenshtein x 1,792 ops/sec ±2.72% (95 runs sampled)
-Benchmark done.
-Fastest test is fast-levenshtein at 4.2x faster than levenshtein-component
-```
-
-You can run this benchmark yourself by doing:
-
-```bash
-$ npm install -g grunt-cli
-$ npm install
-$ npm run build
-$ npm run benchmark
-```

-# ipaddr.js — an IPv6 and IPv4 address manipulation library [](https://travis-ci.org/whitequark/ipaddr.js)
-
-ipaddr.js is a small (1.9K minified and gzipped) library for manipulating
-IP addresses in JavaScript environments. It runs on both CommonJS runtimes
-(e.g. [nodejs]) and in a web browser.
-
-ipaddr.js allows you to verify and parse string representation of an IP
-address, match it against a CIDR range or range list, determine if it falls
-into some reserved ranges (examples include loopback and private ranges),
-and convert between IPv4 and IPv4-mapped IPv6 addresses.
-
-[nodejs]: http://nodejs.org
-
-## Installation
-
-`npm install ipaddr.js`
-
-or
-
-`bower install ipaddr.js`
-
-## API
-
-ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS,
-it is exported from the module:
-
-```js
-var ipaddr = require('ipaddr.js');
-```
-
-The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4.
-
-### Global methods
-
-There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and
-`ipaddr.process`. All of them receive a string as a single parameter.
-
-The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or
-IPv6 address, and `false` otherwise. It does not throw any exceptions.
-
-The `ipaddr.parse` method returns an object representing the IP address,
-or throws an `Error` if the passed string is not a valid representation of an
-IP address.
-
-The `ipaddr.process` method works just like the `ipaddr.parse` one, but it
-automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts
-before returning. It is useful when you have a Node.js instance listening
-on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its
-equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4
-connections on your IPv6-only socket, but the remote address will be mangled.
-Use `ipaddr.process` method to automatically demangle it.
-
-### Object representation
-
-Parsing methods return an object which descends from `ipaddr.IPv6` or
-`ipaddr.IPv4`. These objects share some properties, but most of them differ.
-
-#### Shared properties
-
-One can determine the type of address by calling `addr.kind()`. It will return
-either `"ipv6"` or `"ipv4"`.
-
-An address can be converted back to its string representation with `addr.toString()`.
-Note that this method:
- * does not return the original string used to create the object (in fact, there is
- no way of getting that string)
- * returns a compact representation (when it is applicable)
-
-A `match(range, bits)` method can be used to check if the address falls into a
-certain CIDR range.
-Note that an address can be (obviously) matched only against an address of the same type.
-
-For example:
-
-```js
-var addr = ipaddr.parse("2001:db8:1234::1");
-var range = ipaddr.parse("2001:db8::");
-
-addr.match(range, 32); // => true
-```
-
-Alternatively, `match` can also be called as `match([range, bits])`. In this way,
-it can be used together with the `parseCIDR(string)` method, which parses an IP
-address together with a CIDR range.
-
-For example:
-
-```js
-var addr = ipaddr.parse("2001:db8:1234::1");
-
-addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true
-```
-
-A `range()` method returns one of predefined names for several special ranges defined
-by IP protocols. The exact names (and their respective CIDR ranges) can be looked up
-in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"`
-(the default one) and `"reserved"`.
-
-You can match against your own range list by using
-`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example:
-
-```js
-var rangeList = {
- documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ],
- tunnelProviders: [
- [ ipaddr.parse('2001:470::'), 32 ], // he.net
- [ ipaddr.parse('2001:5c0::'), 32 ] // freenet6
- ]
-};
-ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders"
-```
-
-The addresses can be converted to their byte representation with `toByteArray()`.
-(Actually, JavaScript mostly does not know about byte buffers. They are emulated with
-arrays of numbers, each in range of 0..255.)
-
-```js
-var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com
-bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, <zeroes...>, 0x00, 0x68 ]
-```
-
-The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them
-have the same interface for both protocols, and are similar to global methods.
-
-`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address
-for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser.
-
-`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format.

-[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71
-
-#### IPv6 properties
-
-Sometimes you will want to convert IPv6 not to a compact string representation (with
-the `::` substitution); the `toNormalizedString()` method will return an address where
-all zeroes are explicit.
-
-For example:
-
-```js
-var addr = ipaddr.parse("2001:0db8::0001");
-addr.toString(); // => "2001:db8::1"
-addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1"
-```
-
-The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped
-one, and `toIPv4Address()` will return an IPv4 object address.
-
-To access the underlying binary representation of the address, use `addr.parts`.
-
-```js
-var addr = ipaddr.parse("2001:db8:10::1234:DEAD");
-addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead]
-```
-
-A IPv6 zone index can be accessed via `addr.zoneId`:
-
-```js
-var addr = ipaddr.parse("2001:db8::%eth0");
-addr.zoneId // => 'eth0'
-```
-
-#### IPv4 properties
-
-`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address.
-
-To access the underlying representation of the address, use `addr.octets`.
-
-```js
-var addr = ipaddr.parse("192.168.1.1");
-addr.octets // => [192, 168, 1, 1]
-```
-
-`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or
-false if the netmask is not valid.
-
-```js
-ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28
-ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask() == null
-```
-
-`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length.
-
-```js
-ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0"
-ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248"
-```
-
-`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation.
-```js
-ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255"
-```
-`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation.
-```js
-ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0"
-```
-
-#### Conversion
-
-IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays.
-
-The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object
-if the input satisfies the requirements. For IPv4 it has to be an array of four 8-bit values,
-while for IPv6 it has to be an array of sixteen 8-bit values.
-
-For example:
-```js
-var addr = ipaddr.fromByteArray([0x7f, 0, 0, 1]);
-addr.toString(); // => "127.0.0.1"
-```
-
-or
-
-```js
-var addr = ipaddr.fromByteArray([0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1])
-addr.toString(); // => "2001:db8::1"
-```
-
-Both objects also offer a `toByteArray()` method, which returns an array in network byte order (MSB).
-
-For example:
-```js
-var addr = ipaddr.parse("127.0.0.1");
-addr.toByteArray(); // => [0x7f, 0, 0, 1]
-```
-
-or
-
-```js
-var addr = ipaddr.parse("2001:db8::1");
-addr.toByteArray(); // => [0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1]

-# levn [](https://travis-ci.org/gkz/levn) <a name="levn" />
-__Light ECMAScript (JavaScript) Value Notation__
-Levn is a library which allows you to parse a string into a JavaScript value based on an expected type. It is meant for short amounts of human entered data (eg. config files, command line arguments).
-
-Levn aims to concisely describe JavaScript values in text, and allow for the extraction and validation of those values. Levn uses [type-check](https://github.com/gkz/type-check) for its type format, and to validate the results. MIT license. Version 0.2.5.
-
-__How is this different than JSON?__ levn is meant to be written by humans only, is (due to the previous point) much more concise, can be validated against supplied types, has regex and date literals, and can easily be extended with custom types. On the other hand, it is probably slower and thus less efficient at transporting large amounts of data, which is fine since this is not its purpose.
-
- npm install levn
-
-For updates on levn, [follow me on twitter](https://twitter.com/gkzahariev).
-
-
-## Quick Examples
-
-```js
-var parse = require('levn').parse;
-parse('Number', '2'); // 2
-parse('String', '2'); // '2'
-parse('String', 'levn'); // 'levn'
-parse('String', 'a b'); // 'a b'
-parse('Boolean', 'true'); // true
-
-parse('Date', '#2011-11-11#'); // (Date object)
-parse('Date', '2011-11-11'); // (Date object)
-parse('RegExp', '/[a-z]/gi'); // /[a-z]/gi
-parse('RegExp', 're'); // /re/
-
-parse('Number | String', 'str'); // 'str'
-parse('Number | String', '2'); // 2
-
-parse('[Number]', '[1,2,3]'); // [1,2,3]
-parse('(String, Boolean)', '(hi, false)'); // ['hi', false]
-parse('{a: String, b: Number}', '{a: str, b: 2}'); // {a: 'str', b: 2}
-
-// at the top level, you can ommit surrounding delimiters
-parse('[Number]', '1,2,3'); // [1,2,3]
-parse('(String, Boolean)', 'hi, false'); // ['hi', false]
-parse('{a: String, b: Number}', 'a: str, b: 2'); // {a: 'str', b: 2}
-
-// wildcard - auto choose type
-parse('*', '[hi,(null,[42]),{k: true}]'); // ['hi', [null, [42]], {k: true}]
-```
-## Usage
-
-`require('levn');` returns an object that exposes three properties. `VERSION` is the current version of the library as a string. `parse` and `parsedTypeParse` are functions.
-
-```js
-// parse(type, input, options);
-parse('[Number]', '1,2,3'); // [1, 2, 3]
-
-// parsedTypeParse(parsedType, input, options);
-var parsedType = require('type-check').parseType('[Number]');
-parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
-```
-
-### parse(type, input, options)
-
-`parse` casts the string `input` into a JavaScript value according to the specified `type` in the [type format](https://github.com/gkz/type-check#type-format) (and taking account the optional `options`) and returns the resulting JavaScript value.
-
-##### arguments
-* type - `String` - the type written in the [type format](https://github.com/gkz/type-check#type-format) which to check against
-* input - `String` - the value written in the [levn format](#levn-format)
-* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
-
-##### returns
-`*` - the resulting JavaScript value
-
-##### example
-```js
-parse('[Number]', '1,2,3'); // [1, 2, 3]
-```
-
-### parsedTypeParse(parsedType, input, options)
-
-`parsedTypeParse` casts the string `input` into a JavaScript value according to the specified `type` which has already been parsed (and taking account the optional `options`) and returns the resulting JavaScript value. You can parse a type using the [type-check](https://github.com/gkz/type-check) library's `parseType` function.
-
-##### arguments
-* type - `Object` - the type in the parsed type format which to check against
-* input - `String` - the value written in the [levn format](#levn-format)
-* options - `Maybe Object` - an optional parameter specifying additional [options](#options)
-
-##### returns
-`*` - the resulting JavaScript value
-
-##### example
-```js
-var parsedType = require('type-check').parseType('[Number]');
-parsedTypeParse(parsedType, '1,2,3'); // [1, 2, 3]
-```
-
-## Levn Format
-
-Levn can use the type information you provide to choose the appropriate value to produce from the input. For the same input, it will choose a different output value depending on the type provided. For example, `parse('Number', '2')` will produce the number `2`, but `parse('String', '2')` will produce the string `"2"`.
-
-If you do not provide type information, and simply use `*`, levn will parse the input according the unambiguous "explicit" mode, which we will now detail - you can also set the `explicit` option to true manually in the [options](#options).
-
-* `"string"`, `'string'` are parsed as a String, eg. `"a msg"` is `"a msg"`
-* `#date#` is parsed as a Date, eg. `#2011-11-11#` is `new Date('2011-11-11')`
-* `/regexp/flags` is parsed as a RegExp, eg. `/re/gi` is `/re/gi`
-* `undefined`, `null`, `NaN`, `true`, and `false` are all their JavaScript equivalents
-* `[element1, element2, etc]` is an Array, and the casting procedure is recursively applied to each element. Eg. `[1,2,3]` is `[1,2,3]`.
-* `(element1, element2, etc)` is an tuple, and the casting procedure is recursively applied to each element. Eg. `(1, a)` is `(1, a)` (is `[1, 'a']`).
-* `{key1: val1, key2: val2, ...}` is an Object, and the casting procedure is recursively applied to each property. Eg. `{a: 1, b: 2}` is `{a: 1, b: 2}`.
-* Any test which does not fall under the above, and which does not contain special characters (`[``]``(``)``{``}``:``,`) is a string, eg. `$12- blah` is `"$12- blah"`.
-
-If you do provide type information, you can make your input more concise as the program already has some information about what it expects. Please see the [type format](https://github.com/gkz/type-check#type-format) section of [type-check](https://github.com/gkz/type-check) for more information about how to specify types. There are some rules about what levn can do with the information:
-
-* If a String is expected, and only a String, all characters of the input (including any special ones) will become part of the output. Eg. `[({})]` is `"[({})]"`, and `"hi"` is `'"hi"'`.
-* If a Date is expected, the surrounding `#` can be omitted from date literals. Eg. `2011-11-11` is `new Date('2011-11-11')`.
-* If a RegExp is expected, no flags need to be specified, and the regex is not using any of the special characters,the opening and closing `/` can be omitted - this will have the affect of setting the source of the regex to the input. Eg. `regex` is `/regex/`.
-* If an Array is expected, and it is the root node (at the top level), the opening `[` and closing `]` can be omitted. Eg. `1,2,3` is `[1,2,3]`.
-* If a tuple is expected, and it is the root node (at the top level), the opening `(` and closing `)` can be omitted. Eg. `1, a` is `(1, a)` (is `[1, 'a']`).
-* If an Object is expected, and it is the root node (at the top level), the opening `{` and closing `}` can be omitted. Eg `a: 1, b: 2` is `{a: 1, b: 2}`.
-
-If you list multiple types (eg. `Number | String`), it will first attempt to cast to the first type and then validate - if the validation fails it will move on to the next type and so forth, left to right. You must be careful as some types will succeed with any input, such as String. Thus put String at the end of your list. In non-explicit mode, Date and RegExp will succeed with a large variety of input - also be careful with these and list them near the end if not last in your list.
-
-Whitespace between special characters and elements is inconsequential.
-
-## Options
-
-Options is an object. It is an optional parameter to the `parse` and `parsedTypeParse` functions.
-
-### Explicit
-
-A `Boolean`. By default it is `false`.
-
-__Example:__
-
-```js
-parse('RegExp', 're', {explicit: false}); // /re/
-parse('RegExp', 're', {explicit: true}); // Error: ... does not type check...
-parse('RegExp | String', 're', {explicit: true}); // 're'
-```
-
-`explicit` sets whether to be in explicit mode or not. Using `*` automatically activates explicit mode. For more information, read the [levn format](#levn-format) section.
-
-### customTypes
-
-An `Object`. Empty `{}` by default.
-
-__Example:__
-
-```js
-var options = {
- customTypes: {
- Even: {
- typeOf: 'Number',
- validate: function (x) {
- return x % 2 === 0;
- },
- cast: function (x) {
- return {type: 'Just', value: parseInt(x)};
- }
- }
- }
-}
-parse('Even', '2', options); // 2
-parse('Even', '3', options); // Error: Value: "3" does not type check...
-```
-
-__Another Example:__
-```js
-function Person(name, age){
- this.name = name;
- this.age = age;
-}
-var options = {
- customTypes: {
- Person: {
- typeOf: 'Object',
- validate: function (x) {
- x instanceof Person;
- },
- cast: function (value, options, typesCast) {
- var name, age;
- if ({}.toString.call(value).slice(8, -1) !== 'Object') {
- return {type: 'Nothing'};
- }
- name = typesCast(value.name, [{type: 'String'}], options);
- age = typesCast(value.age, [{type: 'Numger'}], options);
- return {type: 'Just', value: new Person(name, age)};
- }
- }
-}
-parse('Person', '{name: Laura, age: 25}', options); // Person {name: 'Laura', age: 25}
-```
-
-`customTypes` is an object whose keys are the name of the types, and whose values are an object with three properties, `typeOf`, `validate`, and `cast`. For more information about `typeOf` and `validate`, please see the [custom types](https://github.com/gkz/type-check#custom-types) section of type-check.
-
-`cast` is a function which receives three arguments, the value under question, options, and the typesCast function. In `cast`, attempt to cast the value into the specified type. If you are successful, return an object in the format `{type: 'Just', value: CAST-VALUE}`, if you know it won't work, return `{type: 'Nothing'}`. You can use the `typesCast` function to cast any child values. Remember to pass `options` to it. In your function you can also check for `options.explicit` and act accordingly.
-
-## Technical About
-
-`levn` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [type-check](https://github.com/gkz/type-check) to both parse types and validate values. It also uses the [prelude.ls](http://preludels.com/) library.

-[![NPM Version][npm-version-image]][npm-url]
-[![NPM Downloads][npm-downloads-image]][npm-url]

-
-This is a database of all mime types.
-It consists of a single, public JSON file and does not include any logic,
-allowing it to remain as un-opinionated as possible with an API.
-It aggregates data from the following sources:
-
-- http://www.iana.org/assignments/media-types/media-types.xhtml
-- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
-- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
-
-## Installation
-
-```bash
-npm install mime-db
-```
-
-### Database Download
-
-If you're crazy enough to use this in the browser, you can just grab the
-JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
-replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
-as the JSON format may change in the future.
-
-```
-https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
-```
-
-## Usage
-
-```js
-var db = require('mime-db');
-
-// grab data on .js files
-var data = db['application/javascript'];
-```
-
-## Data Structure
-
-The JSON file is a map lookup for lowercased mime types.
-Each mime type has the following properties:
-
-- `.source` - where the mime type is defined.
- If not set, it's probably a custom media type.
- - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
- - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
- - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
-- `.extensions[]` - known extensions associated with this mime type.
-- `.compressible` - whether a file of this type can be gzipped.
-- `.charset` - the default charset associated with this type, if any.
-
-If unknown, every property could be `undefined`.
-
-## Contributing
-
-To edit the database, only make PRs against `src/custom.json` or
-`src/custom-suffix.json`.
-
-The `src/custom.json` file is a JSON object with the MIME type as the keys
-and the values being an object with the following keys:
-
-- `compressible` - leave out if you don't know, otherwise `true`/`false` to
- indicate whether the data represented by the type is typically compressible.
-- `extensions` - include an array of file extensions that are associated with
- the type.
-- `notes` - human-readable notes about the type, typically what the type is.
-- `sources` - include an array of URLs of where the MIME type and the associated
- extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
- links to type aggregating sites and Wikipedia are _not acceptable_.
-
-To update the build, run `npm run build`.
-
-### Adding Custom Media Types
-
-The best way to get new media types included in this library is to register
-them with the IANA. The community registration procedure is outlined in
-[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
-registered with the IANA are automatically pulled into this library.
-
-If that is not possible / feasible, they can be added directly here as a
-"custom" type. To do this, it is required to have a primary source that
-definitively lists the media type. If an extension is going to be listed as
-associateed with this media type, the source must definitively link the
-media type and extension as well.

-
-The ultimate javascript content-type utility.
-
-Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
-
-- __No fallbacks.__ Instead of naively returning the first available type,
- `mime-types` simply returns `false`, so do
- `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
-- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
-- No `.define()` functionality
-- Bug fixes for `.lookup(path)`
-
-Otherwise, the API is compatible with `mime` 1.x.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install mime-types
-```
-
-## Adding Types
-
-All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
-so open a PR there if you'd like to add mime types.
-
-## API
-
-```js
-var mime = require('mime-types')
-```
-
-All functions return `false` if input is invalid or not found.
-
-### mime.lookup(path)
-
-Lookup the content-type associated with a file.
-
-```js
-mime.lookup('json') // 'application/json'
-mime.lookup('.md') // 'text/markdown'
-mime.lookup('file.html') // 'text/html'
-mime.lookup('folder/file.js') // 'application/javascript'
-mime.lookup('folder/.htaccess') // false
-
-mime.lookup('cats') // false
-```
-
-### mime.contentType(type)
-
-Create a full content-type header given a content-type or extension.
-When given an extension, `mime.lookup` is used to get the matching
-content-type, otherwise the given content-type is used. Then if the
-content-type does not already have a `charset` parameter, `mime.charset`
-is used to get the default charset and add to the returned content-type.
-
-```js
-mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
-mime.contentType('file.json') // 'application/json; charset=utf-8'
-mime.contentType('text/html') // 'text/html; charset=utf-8'
-mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
-
-// from a full path
-mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
-```
-
-### mime.extension(type)
-
-Get the default extension for a content-type.
-
-```js
-mime.extension('application/octet-stream') // 'bin'
-```
-
-### mime.charset(type)
-
-Lookup the implied default charset of a content-type.
-
-```js
-mime.charset('text/markdown') // 'UTF-8'
-```
-
-### var type = mime.types[extension]
-
-A map of content-types by extension.
-
-### [extensions...] = mime.extensions[type]
-
-A map of extensions by content-type.

-# mime
-
-Comprehensive MIME type mapping API. Includes all 600+ types and 800+ extensions defined by the Apache project, plus additional types submitted by the node.js community.
-
-## Install
-
-Install with [npm](http://github.com/isaacs/npm):
-
- npm install mime
-
-## API - Queries
-
-### mime.lookup(path)
-Get the mime type associated with a file, if no mime type is found `application/octet-stream` is returned. Performs a case-insensitive lookup using the extension in `path` (the substring after the last '/' or '.'). E.g.
-
- var mime = require('mime');
-
- mime.lookup('/path/to/file.txt'); // => 'text/plain'
- mime.lookup('file.txt'); // => 'text/plain'
- mime.lookup('.TXT'); // => 'text/plain'
- mime.lookup('htm'); // => 'text/html'
-
-### mime.default_type
-Sets the mime type returned when `mime.lookup` fails to find the extension searched for. (Default is `application/octet-stream`.)
-
-### mime.extension(type)
-Get the default extension for `type`
-
- mime.extension('text/html'); // => 'html'
- mime.extension('application/octet-stream'); // => 'bin'
-
-### mime.charsets.lookup()
-
-Map mime-type to charset
-
- mime.charsets.lookup('text/plain'); // => 'UTF-8'
-
-(The logic for charset lookups is pretty rudimentary. Feel free to suggest improvements.)
-
-## API - Defining Custom Types
-
-The following APIs allow you to add your own type mappings within your project. If you feel a type should be included as part of node-mime, see [requesting new types](https://github.com/broofa/node-mime/wiki/Requesting-New-Types).
-
-### mime.define()
-
-Add custom mime/extension mappings
-
- mime.define({
- 'text/x-some-format': ['x-sf', 'x-sft', 'x-sfml'],
- 'application/x-my-type': ['x-mt', 'x-mtt'],
- // etc ...
- });
-
- mime.lookup('x-sft'); // => 'text/x-some-format'
-
-The first entry in the extensions array is returned by `mime.extension()`. E.g.
-
- mime.extension('text/x-some-format'); // => 'x-sf'
-
-### mime.load(filepath)
-
-Load mappings from an Apache ".types" format file
-
- mime.load('./my_project.types');
-
-The .types file format is simple - See the `types` dir for examples.

-An HTTP content negotiator for Node.js
-
-## Installation
-
-```sh
-$ npm install negotiator
-```
-
-## API
-
-```js
-var Negotiator = require('negotiator')
-```
-
-### Accept Negotiation
-
-```js
-availableMediaTypes = ['text/html', 'text/plain', 'application/json']
-
-// The negotiator constructor receives a request object
-negotiator = new Negotiator(request)
-
-// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
-
-negotiator.mediaTypes()
-// -> ['text/html', 'image/jpeg', 'application/*']
-
-negotiator.mediaTypes(availableMediaTypes)
-// -> ['text/html', 'application/json']
-
-negotiator.mediaType(availableMediaTypes)
-// -> 'text/html'
-```
-
-You can check a working example at `examples/accept.js`.
-
-#### Methods
-
-##### mediaType()

-available media types.
-
-### Accept-Language Negotiation
-
-```js
-negotiator = new Negotiator(request)
-
-availableLanguages = ['en', 'es', 'fr']
-
-// Let's say Accept-Language header is 'en;q=0.8, es, pt'
-
-negotiator.languages()
-// -> ['es', 'pt', 'en']
-
-negotiator.languages(availableLanguages)
-// -> ['es', 'en']
-
-language = negotiator.language(availableLanguages)
-// -> 'es'
-```
-

-available languages.
-
-### Accept-Charset Negotiation
-
-```js
-availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
-
-negotiator = new Negotiator(request)
-
-// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
-
-negotiator.charsets()
-// -> ['utf-8', 'iso-8859-1', 'utf-7']
-
-negotiator.charsets(availableCharsets)
-// -> ['utf-8', 'iso-8859-1']
-
-negotiator.charset(availableCharsets)
-// -> 'utf-8'
-```

-##### charsets()
-
-Returns an array of preferred charsets ordered by the client preference.
-
-##### charsets(availableCharsets)
-
-Returns an array of preferred charsets ordered by priority from a list of
-available charsets.
-
-### Accept-Encoding Negotiation
-
-```js
-availableEncodings = ['identity', 'gzip']
-
-negotiator = new Negotiator(request)
-
-// Let's say Accept-Encoding header is 'gzip, compress;q=0.2, identity;q=0.5'

-# Optionator
-<a name="optionator" />
-
-Optionator is an option parsing and help generation library.
-
-## Why?
-The problem with other option parsers, such as `yargs` or `minimist`, is they just accept all input, valid or not.
-With Optionator, if you mistype an option, it will give you an error (with a suggestion for what you meant).
-If you give the wrong type of argument for an option, it will give you an error rather than supplying the wrong input to your application.
-
- $ cmd --halp
- Invalid option '--halp' - perhaps you meant '--help'?
-
- $ cmd --count str
- Invalid value for option 'count' - expected type Int, received value: str.
-
-Over helpful features include reformatting the help text based on the size of the console, so that it fits even if the console is narrow, and accepting not just an array (eg. process.argv), but a string or object as well, making things like testing much easier.
-
-## About
-Optionator uses [type-check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) behind the scenes to cast and verify input according the specified types.
-
-Optionator is used by [Grasp](http://graspjs.com), [eslint](https://github.com/eslint/eslint), and [LiveScript](http://livescript.net).
-
-MIT license. Version 0.4.0
-
- npm install optionator
-
-For updates on Optionator, [follow me on twitter](https://twitter.com/gkzahariev).
-
-## Usage
-`require('optionator');` returns a function. It has one property, `VERSION`, the current version of the library as a string. This function is called with an object specifying your options and other information, see the [settings format section](#settings-format). This in turn returns an object with three properties, `parse`, `generateHelp`, and `generateHelpForOption`, which are all functions.
-
-```js
-var optionator = require('optionator')({
- prepend: 'Usage: cmd [options]',
- append: 'Version 1.0.0',
- options: [{
- option: 'help',
- alias: 'h',
- type: 'Boolean',
- description: 'displays help'
- }, {
- option: 'count',
- alias: 'c',
- type: 'Int',
- description: 'number of things',
- example: 'cmd --count 2'
- }]
-});
-```
-
-### parse(input, parseOptions)
-`parse` processes the `input` according to your settings, and returns an object with the results.
-
-##### arguments
-* input - `[String] | Object | String` - the input you wish to parse
-* parseOptions - `{slice: Int}` - all options optional
- - `slice` specifies how much to slice away from the beginning if the input is an array or string - by default `0` for string, `2` for array (works with `process.argv`)
-
-##### returns
-`Object` - the parsed options, each key is a camelCase version of the option name (specified in dash-case), and each value is the processed value for that option. Positional values are in an array under the `_` key.
-
-##### example
-```js
-parse(['node', 't.js', '--count', '2', 'positional']); // {count: 2, _: ['positional']}
-parse('--count 2 positional'); // {count: 2, _: ['positional']}
-parse({count: 2, _:['positional']}); // {count: 2, _: ['positional']}
-```
-
-### generateHelp(helpOptions)
-`generateHelp` produces help text based on your settings.
-
-##### arguments
-* helpOptions - `{showHidden: Boolean, interpolate: Object}` - all options optional
- - `showHidden` specifies whether to show options with `hidden: true` specified, by default it is `false`
- - `interpolate` specify data to be interpolated in `prepend` and `append` text, `{{key}}` is the format - eg. `generateHelp({interpolate:{version: '0.4.2'}})`, will change this `append` text: `Version {{version}}` to `Version 0.4.2`
-
-##### returns
-`String` - the generated help text
-
-##### example
-```js
-generateHelp(); /*
-"Usage: cmd [options] positional
-
- -h, --help displays help
- -c, --count Int number of things
-
-Version 1.0.0
-"*/
-```
-
-### generateHelpForOption(optionName)
-`generateHelpForOption` produces expanded help text for the specified with `optionName` option. If an `example` was specified for the option, it will be displayed, and if a `longDescription` was specified, it will display that instead of the `description`.
-
-##### arguments
-* optionName - `String` - the name of the option to display
-
-##### returns
-`String` - the generated help text for the option
-
-##### example
-```js
-generateHelpForOption('count'); /*
-"-c, --count Int
-description: number of things
-example: cmd --count 2
-"*/
-```
-
-## Settings Format
-When your `require('optionator')`, you get a function that takes in a settings object. This object has the type:
-
- {
- prepend: Maybe String,
- append: Maybe String,
- options: [{heading: String} | {
- option: String,
- alias: Maybe [String] | String,
- type: Maybe String,
- enum: Maybe [String],
- default: Maybe String,
- restPositional: Maybe Boolean,
- requried: Maybe Boolean,
- overrideRequired: Maybe Bookean,
- dependsOn: Maybe [String] | String,
- description: Maybe String,
- longDescription: Maybe String,
- example: Maybe [String] | String
- }],
- helpStyle: Maybe {
- aliasSeparator: Maybe String,
- typeSeparator: Maybe String,
- descriptionSeparator: Maybe String,
- initialIndent: Maybe Int,
- secondaryIndent: Maybe Int,
- maxPadFactor: Maybe Number

- mutuallyExclusive: Maybe [[String | [String]]],
- concatRepeatedArrays: Maybe Boolean,
- mergeRepeatedObjects: Maybe Boolean
- }
-
-### Top Level Properties
-* `prepend` is an optional string to be placed before the options in the help text
-* `append` is an optional string to be placed after the options in the help text
-* `options` is a required array specifying your options and headings, the options and headings will be displayed in the order specified
-* `helpStyle` is an optional object which enables you to change the default appearance of some aspects of the help text
-* `mutuallyExclusive` is an optional array of arrays of either strings or arrays of strings. The top level array is a list of rules, each rule is a list of elements - each element can be either a string (the name of an option), or a list of strings (a group of option names) - there will be an error if more than one element is present
-* `concatRepeatedArrays` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an array value and is repeated, the subsequent values for the flag will be appended rather than overwriting the original value - eg. option `g` of type `[String]`: `-g a -g b -g c,d` will result in `['a','b','c','d']`
-* `mergeRepeatedObjects` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an object value and is repeated, the subsequent values for the flag will be merged rather than overwriting the original value - eg. option `g` of type `Object`: `-g a:1 -g b:2 -g c:3,d:4` will result in `{a: 1, b: 2, c: 3, d: 4}`
-
-#### Heading Properties
-* `heading` a required string, the name of the heading
-
-#### Option Properties
-* `option` the required name of the option - use dash-case, without the leading dashes
-* `alias` is an optional string or array of strings which specify any aliases for the option
-* `type` is a required string in the [type check](https://github.com/gkz/type-check) [format](https://github.com/gkz/type-check#type-format), this will be used to cast the inputted value and validate it
-* `enum` is an optional array of strings, each string will be parsed by [levn](https://github.com/gkz/levn) - the argument value must be one of the resulting values - each potential value must validate against the specified `type`
-* `default` is a optional string, which will be parsed by [levn](https://github.com/gkz/levn) and used as the default value if none is set - the value must validate against the specified `type`
-* `restPositional` is an optional boolean - if set to `true`, everything after the option will be taken to be a positional argument, even if it looks like a named argument
-* `required` is an optional boolean - if set to `true`, the option parsing will fail if the option is not defined
-* `overrideRequired` is a optional boolean - if set to `true` and the option is used, and there is another option which is required but not set, it will override the need for the required option and there will be no error - this is useful if you have required options and want to use `--help` or `--version` flags
-* `dependsOn` is an optional string or array of strings - if simply a string (the name of another option), it will make sure that that other option is set, if an array of strings, depending on whether `'and'` or `'or'` is first, it will either check whether all (`['and', 'option-a', 'option-b']`), or at least one (`['or', 'option-a', 'option-b']`) other options are set
-* `description` is an optional string, which will be displayed next to the option in the help text
-* `longDescription` is an optional string, it will be displayed instead of the `description` when `generateHelpForOption` is used
-* `example` is an optional string or array of strings with example(s) for the option - these will be displayed when `generateHelpForOption` is used
-
-#### Help Style Properties
-* `aliasSeparator` is an optional string, separates multiple names from each other - default: ' ,'
-* `typeSeparator` is an optional string, separates the type from the names - default: ' '
-* `descriptionSeparator` is an optional string , separates the description from the padded name and type - default: ' '
-* `initialIndent` is an optional int - the amount of indent for options - default: 2
-* `secondaryIndent` is an optional int - the amount of indent if wrapped fully (in addition to the initial indent) - default: 4
-* `maxPadFactor` is an optional number - affects the default level of padding for the names/type, it is multiplied by the average of the length of the names/type - default: 1.5
-
-## Argument Format
-At the highest level there are two types of arguments: named, and positional.
-
-Name arguments of any length are prefixed with `--` (eg. `--go`), and those of one character may be prefixed with either `--` or `-` (eg. `-g`).
-
-There are two types of named arguments: boolean flags (eg. `--problemo`, `-p`) which take no value and result in a `true` if they are present, the falsey `undefined` if they are not present, or `false` if present and explicitly prefixed with `no` (eg. `--no-problemo`). Named arguments with values (eg. `--tseries 800`, `-t 800`) are the other type. If the option has a type `Boolean` it will automatically be made into a boolean flag. Any other type results in a named argument that takes a value.
-
-For more information about how to properly set types to get the value you want, take a look at the [type check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) pages.
-
-You can group single character arguments that use a single `-`, however all except the last must be boolean flags (which take no value). The last may be a boolean flag, or an argument which takes a value - eg. `-ba 2` is equivalent to `-b -a 2`.
-
-Positional arguments are all those values which do not fall under the above - they can be anywhere, not just at the end. For example, in `cmd -b one -a 2 two` where `b` is a boolean flag, and `a` has the type `Number`, there are two positional arguments, `one` and `two`.
-
-Everything after an `--` is positional, even if it looks like a named argument.
-
-You may optionally use `=` to separate option names from values, for example: `--count=2`.
-
-If you specify the option `NUM`, then any argument using a single `-` followed by a number will be valid and will set the value of `NUM`. Eg. `-2` will be parsed into `NUM: 2`.
-
-If duplicate named arguments are present, the last one will be taken.
-
-## Technical About
-`optionator` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [levn](https://github.com/gkz/levn) to cast arguments to their specified type, and uses [type-check](https://github.com/gkz/type-check) to validate values. It also uses the [prelude.ls](http://preludels.com/) library.

-# 1.1.2
-- add `Func.memoize`
-- fix `zip-all` and `zip-with-all` corner case (no input)
-- build with LiveScript 1.4.0
-
-# 1.1.1
-- curry `unique-by`, `minimum-by`
-
-# 1.1.0
-- added `List` functions: `maximum-by`, `minimum-by`, `unique-by`
-- added `List` functions: `at`, `elem-index`, `elem-indices`, `find-index`, `find-indices`
-- added `Str` functions: `capitalize`, `camelize`, `dasherize`
-- added `Func` function: `over` - eg. ``same-length = (==) `over` (.length)``
-- exported `Str.repeat` through main `prelude` object
-- fixed definition of `foldr` and `foldr1`, the new correct definition is backwards incompatible with the old, incorrect one
-- fixed issue with `fix`
-- improved code coverage
-
-# 1.0.3
-- build browser versions
-
-# 1.0.2
-- bug fix for `flatten` - slight change with bug fix, flattens arrays only, not array-like objects
-
-# 1.0.1
-- bug fixes for `drop-while` and `take-while`
-
-# 1.0.0
-* massive update - separated functions into separate modules
-* functions do not accept multiple types anymore - use different versions in their respective modules in some cases (eg. `Obj.map`), or use `chars` or `values` in other cases to transform into a list
-* objects are no longer transformed into functions, simply use `(obj.)` in LiveScript to do that
-* browser version now using browserify - use `prelude = require('prelude-ls')`
-* added `compact`, `split`, `flatten`, `difference`, `intersection`, `union`, `count-by`, `group-by`, `chars`, `unchars`, `apply`
-* added `lists-to-obj` which takes a list of keys and list of values and zips them up into an object, and the converse `obj-to-lists`
-* added `pairs-to-obj` which takes a list of pairs (2 element lists) and creates an object, and the converse `obj-to-pairs`
-* removed `cons`, `append` - use the concat operator
-* removed `compose` - use the compose operator
-* removed `obj-to-func` - use partially applied access (eg. `(obj.)`)
-* removed `length` - use `(.length)`
-* `sort-by` renamed to `sort-with`
-* added new `sort-by`
-* removed `compare` - just use the new `sort-by`
-* `break-it` renamed `break-list`, (`Str.break-str` for the string version)
-* added `Str.repeat` which creates a new string by repeating the input n times
-* `unfold` as alias to `unfoldr` is no longer used
-* fixed up style and compiled with LiveScript 1.1.1
-* use Make instead of Slake
-* greatly improved tests
-
-# 0.6.0
-* fixed various bugs
-* added `fix`, a fixpoint (Y combinator) for anonymous recursive functions
-* added `unfoldr` (alias `unfold`)
-* calling `replicate` with a string now returns a list of strings
-* removed `partial`, just use native partial application in LiveScript using the `_` placeholder, or currying
-* added `sort`, `sortBy`, and `compare`
-
-# 0.5.0
-* removed `lookup` - use (.prop)
-* removed `call` - use (.func arg1, arg2)
-* removed `pluck` - use map (.prop), xs
-* fixed buys wtih `head` and `last`
-* added non-minifed browser version, as `prelude-browser.js`
-* renamed `prelude-min.js` to `prelude-browser-min.js`
-* renamed `zip` to `zipAll`
-* renamed `zipWith` to `zipAllWith`
-* added `zip`, a curried zip that takes only two arguments
-* added `zipWith`, a curried zipWith that takes only two arguments
-
-# 0.4.0
-* added `parition` function
-* added `curry` function
-* removed `elem` function (use `in`)
-* removed `notElem` function (use `not in`)
-
-# 0.3.0
-* added `listToObject`
-* added `unique`
-* added `objToFunc`
-* added support for using strings in map and the like
-* added support for using objects in map and the like
-* added ability to use objects instead of functions in certain cases
-* removed `error` (just use throw)
-* added `tau` constant
-* added `join`
-* added `values`
-* added `keys`
-* added `partial`
-* renamed `log` to `ln`
-* added alias to `head`: `first`
-* added `installPrelude` helper
-
-# 0.2.0
-* removed functions that simply warp operators as you can now use operators as functions in LiveScript
-* `min/max` are now curried and take only 2 arguments
-* added `call`
-
-# 0.1.0
-* initial public release

-# prelude.ls [](https://travis-ci.org/gkz/prelude-ls)
-
-is a functionally oriented utility library. It is powerful and flexible. Almost all of its functions are curried. It is written in, and is the recommended base library for, <a href="http://livescript.net">LiveScript</a>.
-
-See **[the prelude.ls site](http://preludels.com)** for examples, a reference, and more.
-
-You can install via npm `npm install prelude-ls`
-
-### Development
-
-`make test` to test
-
-`make build` to build `lib` from `src`
-
-`make build-browser` to build browser versions

-# promise
-
-This is a simple implementation of Promises. It is a super set of ES6 Promises designed to have readable, performant code and to provide just the extensions that are absolutely necessary for using promises today.
-
-For detailed tutorials on its use, see www.promisejs.org
-
-**N.B.** This promise exposes internals via underscore (`_`) prefixed properties. If you use these, your code will break with each new release.

-
-## Installation
-
-**Server:**
-
- $ npm install promise
-
-**Client:**
-
-You can use browserify on the client, or use the pre-compiled script that acts as a polyfill.
-
-```html
-<script src="https://www.promisejs.org/polyfills/promise-6.1.0.js"></script>
-```
-
-Note that the [es5-shim](https://github.com/es-shims/es5-shim) must be loaded before this library to support browsers pre IE9.
-
-```html
-<script src="https://cdnjs.cloudflare.com/ajax/libs/es5-shim/3.4.0/es5-shim.min.js"></script>
-```
-
-## Usage
-
-The example below shows how you can load the promise library (in a way that works on both client and server using node or browserify). It then demonstrates creating a promise from scratch. You simply call `new Promise(fn)`. There is a complete specification for what is returned by this method in [Promises/A+](http://promises-aplus.github.com/promises-spec/).
-
-```javascript
-var Promise = require('promise');
-
-var promise = new Promise(function (resolve, reject) {
- get('http://www.google.com', function (err, res) {
- if (err) reject(err);
- else resolve(res);
- });
-});
-```
-
-If you need [domains](https://iojs.org/api/domain.html) support, you should instead use:
-
-```js
-var Promise = require('promise/domains');
-```
-
-If you are in an environment that implements `setImmediate` and don't want the optimisations provided by asap, you can use:
-
-```js
-var Promise = require('promise/setimmediate');
-```
-
-If you only want part of the features, e.g. just a pure ES6 polyfill:
-
-```js
-var Promise = require('promise/lib/es6-extensions');
-// or require('promise/domains/es6-extensions');
-// or require('promise/setimmediate/es6-extensions');
-```
-
-## Unhandled Rejections
-
-By default, promises silence any unhandled rejections.
-
-You can enable logging of unhandled ReferenceErrors and TypeErrors via:
-
-```js
-require('promise/lib/rejection-tracking').enable();
-```
-
-Due to the performance cost, you should only do this during development.
-
-You can enable logging of all unhandled rejections if you need to debug an exception you think is being swallowed by promises:
-
-```js
-require('promise/lib/rejection-tracking').enable(
- {allRejections: true}
-);
-```
-
-Due to the high probability of false positives, I only recommend using this when debugging specific issues that you think may be being swallowed. For the preferred debugging method, see `Promise#done(onFulfilled, onRejected)`.
-
-`rejection-tracking.enable(options)` takes the following options:
-
- - allRejections (`boolean`) - track all exceptions, not just reference errors and type errors. Note that this has a high probability of resulting in false positives if your code loads data optimisticly
- - whitelist (`Array<ErrorConstructor>`) - this defaults to `[ReferenceError, TypeError]` but you can override it with your own list of error constructors to track.
- - `onUnhandled(id, error)` and `onHandled(id, error)` - you can use these to provide your own customised display for errors. Note that if possible you should indicate that the error was a false positive if `onHandled` is called. `onHandled` is only called if `onUnhandled` has already been called.
-
-To reduce the chance of false-positives there is a delay of up to 2 seconds before errors are logged. This means that if you attach an error handler within 2 seconds, it won't be logged as a false positive. ReferenceErrors and TypeErrors are only subject to a 100ms delay due to the higher likelihood that the error is due to programmer error.
-
-## API
-
-Before all examples, you will need:
-
-```js
-var Promise = require('promise');
-```
-
-### new Promise(resolver)
-
-This creates and returns a new promise. `resolver` must be a function. The `resolver` function is passed two arguments:
-
- 1. `resolve` should be called with a single argument. If it is called with a non-promise value then the promise is fulfilled with that value. If it is called with a promise (A) then the returned promise takes on the state of that new promise (A).
- 2. `reject` should be called with a single argument. The returned promise will be rejected with that argument.
-
-### Static Functions
-
- These methods are invoked by calling `Promise.methodName`.
-
-#### Promise.resolve(value)
-
-(deprecated aliases: `Promise.from(value)`, `Promise.cast(value)`)
-
-Converts values and foreign promises into Promises/A+ promises. If you pass it a value then it returns a Promise for that value. If you pass it something that is close to a promise (such as a jQuery attempt at a promise) it returns a Promise that takes on the state of `value` (rejected or fulfilled).
-
-#### Promise.reject(value)
-
-Returns a rejected promise with the given value.
-
-#### Promise.all(array)
-
-Returns a promise for an array. If it is called with a single argument that `Array.isArray` then this returns a promise for a copy of that array with any promises replaced by their fulfilled values. e.g.
-
-```js
-Promise.all([Promise.resolve('a'), 'b', Promise.resolve('c')])
- .then(function (res) {
- assert(res[0] === 'a')
- assert(res[1] === 'b')
- assert(res[2] === 'c')
- })
-```
-
-#### Promise.denodeify(fn)
-
-_Non Standard_
-
-Takes a function which accepts a node style callback and returns a new function that returns a promise instead.
-
-e.g.
-
-```javascript
-var fs = require('fs')
-
-var read = Promise.denodeify(fs.readFile)
-var write = Promise.denodeify(fs.writeFile)
-
-var p = read('foo.json', 'utf8')
- .then(function (str) {
- return write('foo.json', JSON.stringify(JSON.parse(str), null, ' '), 'utf8')
- })
-```
-
-#### Promise.nodeify(fn)
-
-_Non Standard_
-
-The twin to `denodeify` is useful when you want to export an API that can be used by people who haven't learnt about the brilliance of promises yet.
-
-```javascript
-module.exports = Promise.nodeify(awesomeAPI)
-function awesomeAPI(a, b) {
- return download(a, b)
-}
-```
-
-If the last argument passed to `module.exports` is a function, then it will be treated like a node.js callback and not parsed on to the child function, otherwise the API will just return a promise.
-
-### Prototype Methods
-
-These methods are invoked on a promise instance by calling `myPromise.methodName`
-
-### Promise#then(onFulfilled, onRejected)
-
-This method follows the [Promises/A+ spec](http://promises-aplus.github.io/promises-spec/). It explains things very clearly so I recommend you read it.
-
-Either `onFulfilled` or `onRejected` will be called and they will not be called more than once. They will be passed a single argument and will always be called asynchronously (in the next turn of the event loop).
-
-If the promise is fulfilled then `onFulfilled` is called. If the promise is rejected then `onRejected` is called.
-
-The call to `.then` also returns a promise. If the handler that is called returns a promise, the promise returned by `.then` takes on the state of that returned promise. If the handler that is called returns a value that is not a promise, the promise returned by `.then` will be fulfilled with that value. If the handler that is called throws an exception then the promise returned by `.then` is rejected with that exception.
-
-#### Promise#catch(onRejected)
-
-Sugar for `Promise#then(null, onRejected)`, to mirror `catch` in synchronous code.
-
-#### Promise#done(onFulfilled, onRejected)
-
-_Non Standard_
-
-The same semantics as `.then` except that it does not return a promise and any exceptions are re-thrown so that they can be logged (crashing the application in non-browser environments)
-
-#### Promise#nodeify(callback)
-
-_Non Standard_
-
-If `callback` is `null` or `undefined` it just returns `this`. If `callback` is a function it is called with rejection reason as the first argument and result as the second argument (as per the node.js convention).
-
-This lets you write API functions that look like:
-
-```javascript
-function awesomeAPI(foo, bar, callback) {
- return internalAPI(foo, bar)
- .then(parseResult)
- .then(null, retryErrors)
- .nodeify(callback)
-}
-```
-
-People who use typical node.js style callbacks will be able to just pass a callback and get the expected behavior. The enlightened people can not pass a callback and will get awesome promises.

-# type-check [](https://travis-ci.org/gkz/type-check)
-
-<a name="type-check" />
-
-`type-check` is a library which allows you to check the types of JavaScript values at runtime with a Haskell like type syntax. It is great for checking external input, for testing, or even for adding a bit of safety to your internal code. It is a major component of [levn](https://github.com/gkz/levn). MIT license. Version 0.3.2. Check out the [demo](http://gkz.github.io/type-check/).
-
-For updates on `type-check`, [follow me on twitter](https://twitter.com/gkzahariev).
-
- npm install type-check
-
-## Quick Examples
-
-```js
-// Basic types:
-var typeCheck = require('type-check').typeCheck;
-typeCheck('Number', 1); // true
-typeCheck('Number', 'str'); // false
-typeCheck('Error', new Error); // true
-typeCheck('Undefined', undefined); // true
-
-// Comment
-typeCheck('count::Number', 1); // true
-
-// One type OR another type:
-typeCheck('Number | String', 2); // true
-typeCheck('Number | String', 'str'); // true
-
-// Wildcard, matches all types:
-typeCheck('*', 2) // true
-
-// Array, all elements of a single type:
-typeCheck('[Number]', [1, 2, 3]); // true
-typeCheck('[Number]', [1, 'str', 3]); // false
-
-// Tuples, or fixed length arrays with elements of different types:
-typeCheck('(String, Number)', ['str', 2]); // true
-typeCheck('(String, Number)', ['str']); // false
-typeCheck('(String, Number)', ['str', 2, 5]); // false
-
-// Object properties:
-typeCheck('{x: Number, y: Boolean}', {x: 2, y: false}); // true
-typeCheck('{x: Number, y: Boolean}', {x: 2}); // false
-typeCheck('{x: Number, y: Maybe Boolean}', {x: 2}); // true
-typeCheck('{x: Number, y: Boolean}', {x: 2, y: false, z: 3}); // false
-typeCheck('{x: Number, y: Boolean, ...}', {x: 2, y: false, z: 3}); // true
-
-// A particular type AND object properties:
-typeCheck('RegExp{source: String, ...}', /re/i); // true
-typeCheck('RegExp{source: String, ...}', {source: 're'}); // false
-
-// Custom types:
-var opt = {customTypes:
- {Even: { typeOf: 'Number', validate: function(x) { return x % 2 === 0; }}}};
-typeCheck('Even', 2, opt); // true
-
-// Nested:
-var type = '{a: (String, [Number], {y: Array, ...}), b: Error{message: String, ...}}'
-typeCheck(type, {a: ['hi', [1, 2, 3], {y: [1, 'ms']}], b: new Error('oh no')}); // true
-```
-
-Check out the [type syntax format](#syntax) and [guide](#guide).
-
-## Usage
-
-`require('type-check');` returns an object that exposes four properties. `VERSION` is the current version of the library as a string. `typeCheck`, `parseType`, and `parsedTypeCheck` are functions.
-
-```js
-// typeCheck(type, input, options);
-typeCheck('Number', 2); // true
-
-// parseType(type);
-var parsedType = parseType('Number'); // object
-
-// parsedTypeCheck(parsedType, input, options);
-parsedTypeCheck(parsedType, 2); // true
-```
-
-### typeCheck(type, input, options)
-
-`typeCheck` checks a JavaScript value `input` against `type` written in the [type format](#type-format) (and taking account the optional `options`) and returns whether the `input` matches the `type`.
-
-##### arguments
-* type - `String` - the type written in the [type format](#type-format) which to check against
-* input - `*` - any JavaScript value, which is to be checked against the type
-* options - `Maybe Object` - an optional parameter specifying additional options, currently the only available option is specifying [custom types](#custom-types)
-
-##### returns
-`Boolean` - whether the input matches the type
-
-##### example
-```js
-typeCheck('Number', 2); // true
-```
-
-### parseType(type)
-
-`parseType` parses string `type` written in the [type format](#type-format) into an object representing the parsed type.
-
-##### arguments
-* type - `String` - the type written in the [type format](#type-format) which to parse
-
-##### returns
-`Object` - an object in the parsed type format representing the parsed type
-
-##### example
-```js
-parseType('Number'); // [{type: 'Number'}]
-```
-### parsedTypeCheck(parsedType, input, options)
-
-`parsedTypeCheck` checks a JavaScript value `input` against parsed `type` in the parsed type format (and taking account the optional `options`) and returns whether the `input` matches the `type`. Use this in conjunction with `parseType` if you are going to use a type more than once.
-
-##### arguments
-* type - `Object` - the type in the parsed type format which to check against
-* input - `*` - any JavaScript value, which is to be checked against the type
-* options - `Maybe Object` - an optional parameter specifying additional options, currently the only available option is specifying [custom types](#custom-types)
-
-##### returns
-`Boolean` - whether the input matches the type
-
-##### example
-```js
-parsedTypeCheck([{type: 'Number'}], 2); // true
-var parsedType = parseType('String');
-parsedTypeCheck(parsedType, 'str'); // true
-```

-## Type Format
-
-### Syntax
-
-White space is ignored. The root node is a __Types__.
-
-* __Identifier__ = `[\$\w]+` - a group of any lower or upper case letters, numbers, underscores, or dollar signs - eg. `String`
-* __Type__ = an `Identifier`, an `Identifier` followed by a `Structure`, just a `Structure`, or a wildcard `*` - eg. `String`, `Object{x: Number}`, `{x: Number}`, `Array{0: String, 1: Boolean, length: Number}`, `*`
-* __Types__ = optionally a comment (an `Indentifier` followed by a `::`), optionally the identifier `Maybe`, one or more `Type`, separated by `|` - eg. `Number`, `String | Date`, `Maybe Number`, `Maybe Boolean | String`
-* __Structure__ = `Fields`, or a `Tuple`, or an `Array` - eg. `{x: Number}`, `(String, Number)`, `[Date]`
-* __Fields__ = a `{`, followed one or more `Field` separated by a comma `,` (trailing comma `,` is permitted), optionally an `...` (always preceded by a comma `,`), followed by a `}` - eg. `{x: Number, y: String}`, `{k: Function, ...}`
-* __Field__ = an `Identifier`, followed by a colon `:`, followed by `Types` - eg. `x: Date | String`, `y: Boolean`
-* __Tuple__ = a `(`, followed by one or more `Types` separated by a comma `,` (trailing comma `,` is permitted), followed by a `)` - eg `(Date)`, `(Number, Date)`
-* __Array__ = a `[` followed by exactly one `Types` followed by a `]` - eg. `[Boolean]`, `[Boolean | Null]`
-
-### Guide
-
-`type-check` uses `Object.toString` to find out the basic type of a value. Specifically,
-
-```js
-{}.toString.call(VALUE).slice(8, -1)
-{}.toString.call(true).slice(8, -1) // 'Boolean'
-```
-A basic type, eg. `Number`, uses this check. This is much more versatile than using `typeof` - for example, with `document`, `typeof` produces `'object'` which isn't that useful, and our technique produces `'HTMLDocument'`.
-
-You may check for multiple types by separating types with a `|`. The checker proceeds from left to right, and passes if the value is any of the types - eg. `String | Boolean` first checks if the value is a string, and then if it is a boolean. If it is none of those, then it returns false.
-
-Adding a `Maybe` in front of a list of multiple types is the same as also checking for `Null` and `Undefined` - eg. `Maybe String` is equivalent to `Undefined | Null | String`.
-
-You may add a comment to remind you of what the type is for by following an identifier with a `::` before a type (or multiple types). The comment is simply thrown out.
-
-The wildcard `*` matches all types.
-
-There are three types of structures for checking the contents of a value: 'fields', 'tuple', and 'array'.
-
-If used by itself, a 'fields' structure will pass with any type of object as long as it is an instance of `Object` and the properties pass - this allows for duck typing - eg. `{x: Boolean}`.
-
-To check if the properties pass, and the value is of a certain type, you can specify the type - eg. `Error{message: String}`.
-
-If you want to make a field optional, you can simply use `Maybe` - eg. `{x: Boolean, y: Maybe String}` will still pass if `y` is undefined (or null).
-
-If you don't care if the value has properties beyond what you have specified, you can use the 'etc' operator `...` - eg. `{x: Boolean, ...}` will match an object with an `x` property that is a boolean, and with zero or more other properties.
-
-For an array, you must specify one or more types (separated by `|`) - it will pass for something of any length as long as each element passes the types provided - eg. `[Number]`, `[Number | String]`.
-
-A tuple checks for a fixed number of elements, each of a potentially different type. Each element is separated by a comma - eg. `(String, Number)`.
-
-An array and tuple structure check that the value is of type `Array` by default, but if another type is specified, they will check for that instead - eg. `Int32Array[Number]`. You can use the wildcard `*` to search for any type at all.
-
-Check out the [type precedence](https://github.com/zaboco/type-precedence) library for type-check.
-
-## Options
-
-Options is an object. It is an optional parameter to the `typeCheck` and `parsedTypeCheck` functions. The only current option is `customTypes`.
-
-<a name="custom-types" />
-### Custom Types
-
-__Example:__
-
-```js
-var options = {
- customTypes: {
- Even: {
- typeOf: 'Number',
- validate: function(x) {
- return x % 2 === 0;
- }
- }
- }
-};
-typeCheck('Even', 2, options); // true
-typeCheck('Even', 3, options); // false
-```
-
-`customTypes` allows you to set up custom types for validation. The value of this is an object. The keys of the object are the types you will be matching. Each value of the object will be an object having a `typeOf` property - a string, and `validate` property - a function.
-
-The `typeOf` property is the type the value should be, and `validate` is a function which should return true if the value is of that type. `validate` receives one parameter, which is the value that we are checking.
-
-## Technical About
-
-`type-check` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It also uses the [prelude.ls](http://preludels.com/) library.

-# node-url
-
-[](https://travis-ci.org/defunctzombie/node-url)
-
-This module has utilities for URL resolution and parsing meant to have feature parity with node.js core [url](http://nodejs.org/api/url.html) module.
-
-```js
-var url = require('url');
-```
-
-## api
-
-Parsed URL objects have some or all of the following fields, depending on
-whether or not they exist in the URL string. Any parts that are not in the URL
-string will not be in the parsed object. Examples are shown for the URL
-
-`'http://user:pass@host.com:8080/p/a/t/h?query=string#hash'`
-
-* `href`: The full URL that was originally parsed. Both the protocol and host are lowercased.
-
- Example: `'http://user:pass@host.com:8080/p/a/t/h?query=string#hash'`
-
-* `protocol`: The request protocol, lowercased.
-
- Example: `'http:'`
-
-* `host`: The full lowercased host portion of the URL, including port
- information.
-
- Example: `'host.com:8080'`
-
-* `auth`: The authentication information portion of a URL.
-
- Example: `'user:pass'`
-
-* `hostname`: Just the lowercased hostname portion of the host.
-
- Example: `'host.com'`
-
-* `port`: The port number portion of the host.
-
- Example: `'8080'`
-
-* `pathname`: The path section of the URL, that comes after the host and
- before the query, including the initial slash if present.
-
- Example: `'/p/a/t/h'`
-
-* `search`: The 'query string' portion of the URL, including the leading
- question mark.
-
- Example: `'?query=string'`
-
-* `path`: Concatenation of `pathname` and `search`.
-
- Example: `'/p/a/t/h?query=string'`
-
-* `query`: Either the 'params' portion of the query string, or a
- querystring-parsed object.
-
- Example: `'query=string'` or `{'query':'string'}`
-
-* `hash`: The 'fragment' portion of the URL including the pound-sign.
-
- Example: `'#hash'`
-
-The following methods are provided by the URL module:
-
-### url.parse(urlStr, [parseQueryString], [slashesDenoteHost])
-
-Take a URL string, and return an object.
-
-Pass `true` as the second argument to also parse
-the query string using the `querystring` module.
-Defaults to `false`.
-
-Pass `true` as the third argument to treat `//foo/bar` as
-`{ host: 'foo', pathname: '/bar' }` rather than
-`{ pathname: '//foo/bar' }`. Defaults to `false`.
-
-### url.format(urlObj)
-
-Take a parsed URL object, and return a formatted URL string.
-
-* `href` will be ignored.
-* `protocol` is treated the same with or without the trailing `:` (colon).
- * The protocols `http`, `https`, `ftp`, `gopher`, `file` will be
- postfixed with `://` (colon-slash-slash).
- * All other protocols `mailto`, `xmpp`, `aim`, `sftp`, `foo`, etc will
- be postfixed with `:` (colon)
-* `auth` will be used if present.
-* `hostname` will only be used if `host` is absent.
-* `port` will only be used if `host` is absent.
-* `host` will be used in place of `hostname` and `port`
-* `pathname` is treated the same with or without the leading `/` (slash)
-* `search` will be used in place of `query`
-* `query` (object; see `querystring`) will only be used if `search` is absent.
-* `search` is treated the same with or without the leading `?` (question mark)
-* `hash` is treated the same with or without the leading `#` (pound sign, anchor)
-
-### url.resolve(from, to)
-
-Take a base URL, and a href URL, and resolve them as a browser would for
-an anchor tag. Examples:
-
- url.resolve('/one/two/three', 'four') // '/one/two/four'
- url.resolve('http://example.com/', '/one') // 'http://example.com/one'
- url.resolve('http://example.com/one', '/two') // 'http://example.com/two'

-
-A robust Punycode converter that fully complies to [RFC 3492](http://tools.ietf.org/html/rfc3492) and [RFC 5891](http://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
-
-This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
-
-* [The C example code from RFC 3492](http://tools.ietf.org/html/rfc3492#appendix-C)

-## API
-
-### `punycode.decode(string)`
-
-Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
-
-```js
-// decode domain name parts
-punycode.decode('maana-pta'); // 'mañana'
-punycode.decode('--dqo34k'); // '☃-⌘'
-```
-
-### `punycode.encode(string)`
-
-Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
-
-```js
-// encode domain name parts
-punycode.encode('mañana'); // 'maana-pta'
-punycode.encode('☃-⌘'); // '--dqo34k'
-```
-
-### `punycode.toUnicode(input)`
-
-Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
-
-```js
-// decode domain names
-punycode.toUnicode('xn--maana-pta.com');
-// → 'mañana.com'
-punycode.toUnicode('xn----dqo34k.com');
-// → '☃-⌘.com'
-
-// decode email addresses
-punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
-// → 'джумла@джpумлатест.bрфa'
-```
-
-### `punycode.toASCII(input)`
-
-Converts a Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that's already in ASCII.
-
-```js
-// encode domain names
-punycode.toASCII('mañana.com');
-// → 'xn--maana-pta.com'
-punycode.toASCII('☃-⌘.com');
-// → 'xn----dqo34k.com'
-
-// encode email addresses
-punycode.toASCII('джумла@джpумлатест.bрфa');
-// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
-```
-
-### `punycode.ucs2`
-
-#### `punycode.ucs2.decode(string)`
-
-Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
-
-```js
-punycode.ucs2.decode('abc');
-// → [0x61, 0x62, 0x63]
-// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
-punycode.ucs2.decode('\uD834\uDF06');
-// → [0x1D306]
-```
-
-#### `punycode.ucs2.encode(codePoints)`
-
-Creates a string based on an array of numeric code point values.
-
-```js
-punycode.ucs2.encode([0x61, 0x62, 0x63]);
-// → 'abc'
-punycode.ucs2.encode([0x1D306]);
-// → '\uD834\uDF06'
-```
-
-### `punycode.version`
-
-A string representing the current Punycode.js version number.
-
-## Unit tests & code coverage
-
-After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
-
-Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
-
-To generate the code coverage report, use `grunt cover`.
-
-Feel free to fork if you see possible improvements!

-In Praise of Idleness
-
-By Bertrand Russell
-
-[1932]
-
-Like most of my generation, I was brought up on the saying: 'Satan finds some mischief for idle hands to do.' Being a highly virtuous child, I believed all that I was told, and acquired a conscience which has kept me working hard down to the present moment. But although my conscience has controlled my actions, my opinions have undergone a revolution. I think that there is far too much work done in the world, that immense harm is caused by the belief that work is virtuous, and that what needs to be preached in modern industrial countries is quite different from what always has been preached. Everyone knows the story of the traveler in Naples who saw twelve beggars lying in the sun (it was before the days of Mussolini), and offered a lira to the laziest of them. Eleven of them jumped up to claim it, so he gave it to the twelfth. this traveler was on the right lines. But in countries which do not enjoy Mediterranean sunshine idleness is more difficult, and a great public propaganda will be required to inaugurate it. I hope that, after reading the following pages, the leaders of the YMCA will start a campaign to induce good young men to do nothing. If so, I shall not have lived in vain.
-
-Before advancing my own arguments for laziness, I must dispose of one which I cannot accept. Whenever a person who already has enough to live on proposes to engage in some everyday kind of job, such as school-teaching or typing, he or she is told that such conduct takes the bread out of other people's mouths, and is therefore wicked. If this argument were valid, it would only be necessary for us all to be idle in order that we should all have our mouths full of bread. What people who say such things forget is that what a man earns he usually spends, and in spending he gives employment. As long as a man spends his income, he puts just as much bread into people's mouths in spending as he takes out of other people's mouths in earning. The real villain, from this point of view, is the man who saves. If he merely puts his savings in a stocking, like the proverbial French peasant, it is obvious that they do not give employment. If he invests his savings, the matter is less obvious, and different cases arise.
-
-One of the commonest things to do with savings is to lend them to some Government. In view of the fact that the bulk of the public expenditure of most civilized Governments consists in payment for past wars or preparation for future wars, the man who lends his money to a Government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man's economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it in drink or gambling.
-
-But, I shall be told, the case is quite different when savings are invested in industrial enterprises. When such enterprises succeed, and produce something useful, this may be conceded. In these days, however, no one will deny that most enterprises fail. That means that a large amount of human labor, which might have been devoted to producing something that could be enjoyed, was expended on producing machines which, when produced, lay idle and did no good to anyone. The man who invests his savings in a concern that goes bankrupt is therefore injuring others as well as himself. If he spent his money, say, in giving parties for his friends, they (we may hope) would get pleasure, and so would all those upon whom he spent money, such as the butcher, the baker, and the bootlegger. But if he spends it (let us say) upon laying down rails for surface card in some place where surface cars turn out not to be wanted, he has diverted a mass of labor into channels where it gives pleasure to no one. Nevertheless, when he becomes poor through failure of his investment he will be regarded as a victim of undeserved misfortune, whereas the gay spendthrift, who has spent his money philanthropically, will be despised as a fool and a frivolous person.
-
-All this is only preliminary. I want to say, in all seriousness, that a great deal of harm is being done in the modern world by belief in the virtuousness of work, and that the road to happiness and prosperity lies in an organized diminution of work.
-
-First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid. The second kind is capable of indefinite extension: there are not only those who give orders, but those who give advice as to what orders should be given. Usually two opposite kinds of advice are given simultaneously by two organized bodies of men; this is called politics. The skill required for this kind of work is not knowledge of the subjects as to which advice is given, but knowledge of the art of persuasive speaking and writing, i.e. of advertising.
-
-Throughout Europe, though not in America, there is a third class of men, more respected than either of the classes of workers. There are men who, through ownership of land, are able to make others pay for the privilege of being allowed to exist and to work. These landowners are idle, and I might therefore be expected to praise them. Unfortunately, their idleness is only rendered possible by the industry of others; indeed their desire for comfortable idleness is historically the source of the whole gospel of work. The last thing they have ever wished is that others should follow their example.
-
-From the beginning of civilization until the Industrial Revolution, a man could, as a rule, produce by hard work little more than was required for the subsistence of himself and his family, although his wife worked at least as hard as he did, and his children added their labor as soon as they were old enough to do so. The small surplus above bare necessaries was not left to those who produced it, but was appropriated by warriors and priests. In times of famine there was no surplus; the warriors and priests, however, still secured as much as at other times, with the result that many of the workers died of hunger. This system persisted in Russia until 1917 [1], and still persists in the East; in England, in spite of the Industrial Revolution, it remained in full force throughout the Napoleonic wars, and until a hundred years ago, when the new class of manufacturers acquired power. In America, the system came to an end with the Revolution, except in the South, where it persisted until the Civil War. A system which lasted so long and ended so recently has naturally left a profound impress upon men's thoughts and opinions. Much that we take for granted about the desirability of work is derived from this system, and, being pre-industrial, is not adapted to the modern world. Modern technique has made it possible for leisure, within limits, to be not the prerogative of small privileged classes, but a right evenly distributed throughout the community. The morality of work is the morality of slaves, and the modern world has no need of slavery.
-
-It is obvious that, in primitive communities, peasants, left to themselves, would not have parted with the slender surplus upon which the warriors and priests subsisted, but would have either produced less or consumed more. At first, sheer force compelled them to produce and part with the surplus. Gradually, however, it was found possible to induce many of them to accept an ethic according to which it was their duty to work hard, although part of their work went to support others in idleness. By this means the amount of compulsion required was lessened, and the expenses of government were diminished. To this day, 99 per cent of British wage-earners would be genuinely shocked if it were proposed that the King should not have a larger income than a working man. The conception of duty, speaking historically, has been a means used by the holders of power to induce others to live for the interests of their masters rather than for their own. Of course the holders of power conceal this fact from themselves by managing to believe that their interests are identical with the larger interests of humanity. Sometimes this is true; Athenian slave-owners, for instance, employed part of their leisure in making a permanent contribution to civilization which would have been impossible under a just economic system. Leisure is essential to civilization, and in former times leisure for the few was only rendered possible by the labors of the many. But their labors were valuable, not because work is good, but because leisure is good. And with modern technique it would be possible to distribute leisure justly without injury to civilization.
-
-Modern technique has made it possible to diminish enormously the amount of labor required to secure the necessaries of life for everyone. This was made obvious during the war. At that time all the men in the armed forces, and all the men and women engaged in the production of munitions, all the men and women engaged in spying, war propaganda, or Government offices connected with the war, were withdrawn from productive occupations. In spite of this, the general level of well-being among unskilled wage-earners on the side of the Allies was higher than before or since. The significance of this fact was concealed by finance: borrowing made it appear as if the future was nourishing the present. But that, of course, would have been impossible; a man cannot eat a loaf of bread that does not yet exist. The war showed conclusively that, by the scientific organization of production, it is possible to keep modern populations in fair comfort on a small part of the working capacity of the modern world. If, at the end of the war, the scientific organization, which had been created in order to liberate men for fighting and munition work, had been preserved, and the hours of the week had been cut down to four, all would have been well. Instead of that the old chaos was restored, those whose work was demanded were made to work long hours, and the rest were left to starve as unemployed. Why? Because work is a duty, and a man should not receive wages in proportion to what he has produced, but in proportion to his virtue as exemplified by his industry.
-
-This is the morality of the Slave State, applied in circumstances totally unlike those in which it arose. No wonder the result has been disastrous. Let us take an illustration. Suppose that, at a given moment, a certain number of people are engaged in the manufacture of pins. They make as many pins as the world needs, working (say) eight hours a day. Someone makes an invention by which the same number of men can make twice as many pins: pins are already so cheap that hardly any more will be bought at a lower price. In a sensible world, everybody concerned in the manufacturing of pins would take to working four hours instead of eight, and everything else would go on as before. But in the actual world this would be thought demoralizing. The men still work eight hours, there are too many pins, some employers go bankrupt, and half the men previously concerned in making pins are thrown out of work. There is, in the end, just as much leisure as on the other plan, but half the men are totally idle while half are still overworked. In this way, it is insured that the unavoidable leisure shall cause misery all round instead of being a universal source of happiness. Can anything more insane be imagined?
-
-The idea that the poor should have leisure has always been shocking to the rich. In England, in the early nineteenth century, fifteen hours was the ordinary day's work for a man; children sometimes did as much, and very commonly did twelve hours a day. When meddlesome busybodies suggested that perhaps these hours were rather long, they were told that work kept adults from drink and children from mischief. When I was a child, shortly after urban working men had acquired the vote, certain public holidays were established by law, to the great indignation of the upper classes. I remember hearing an old Duchess say: 'What do the poor want with holidays? They ought to work.' People nowadays are less frank, but the sentiment persists, and is the source of much of our economic confusion.
-
-Let us, for a moment, consider the ethics of work frankly, without superstition. Every human being, of necessity, consumes, in the course of his life, a certain amount of the produce of human labor. Assuming, as we may, that labor is on the whole disagreeable, it is unjust that a man should consume more than he produces. Of course he may provide services rather than commodities, like a medical man, for example; but he should provide something in return for his board and lodging. to this extent, the duty of work must be admitted, but to this extent only.
-
-I shall not dwell upon the fact that, in all modern societies outside the USSR, many people escape even this minimum amount of work, namely all those who inherit money and all those who marry money. I do not think the fact that these people are allowed to be idle is nearly so harmful as the fact that wage-earners are expected to overwork or starve.
-
-If the ordinary wage-earner worked four hours a day, there would be enough for everybody and no unemployment -- assuming a certain very moderate amount of sensible organization. This idea shocks the well-to-do, because they are convinced that the poor would not know how to use so much leisure. In America men often work long hours even when they are well off; such men, naturally, are indignant at the idea of leisure for wage-earners, except as the grim punishment of unemployment; in fact, they dislike leisure even for their sons. Oddly enough, while they wish their sons to work so hard as to have no time to be civilized, they do not mind their wives and daughters having no work at all. the snobbish admiration of uselessness, which, in an aristocratic society, extends to both sexes, is, under a plutocracy, confined to women; this, however, does not make it any more in agreement with common sense.
-
-The wise use of leisure, it must be conceded, is a product of civilization and education. A man who has worked long hours all his life will become bored if he becomes suddenly idle. But without a considerable amount of leisure a man is cut off from many of the best things. There is no longer any reason why the bulk of the population should suffer this deprivation; only a foolish asceticism, usually vicarious, makes us continue to insist on work in excessive quantities now that the need no longer exists.
-
-In the new creed which controls the government of Russia, while there is much that is very different from the traditional teaching of the West, there are some things that are quite unchanged. The attitude of the governing classes, and especially of those who conduct educational propaganda, on the subject of the dignity of labor, is almost exactly that which the governing classes of the world have always preached to what were called the 'honest poor'. Industry, sobriety, willingness to work long hours for distant advantages, even submissiveness to authority, all these reappear; moreover authority still represents the will of the Ruler of the Universe, Who, however, is now called by a new name, Dialectical Materialism.
-
-The victory of the proletariat in Russia has some points in common with the victory of the feminists in some other countries. For ages, men had conceded the superior saintliness of women, and had consoled women for their inferiority by maintaining that saintliness is more desirable than power. At last the feminists decided that they would have both, since the pioneers among them believed all that the men had told them about the desirability of virtue, but not what they had told them about the worthlessness of political power. A similar thing has happened in Russia as regards manual work. For ages, the rich and their sycophants have written in praise of 'honest toil', have praised the simple life, have professed a religion which teaches that the poor are much more likely to go to heaven than the rich, and in general have tried to make manual workers believe that there is some special nobility about altering the position of matter in space, just as men tried to make women believe that they derived some special nobility from their sexual enslavement. In Russia, all this teaching about the excellence of manual work has been taken seriously, with the result that the manual worker is more honored than anyone else. What are, in essence, revivalist appeals are made, but not for the old purposes: they are made to secure shock workers for special tasks. Manual work is the ideal which is held before the young, and is the basis of all ethical teaching.
-
-For the present, possibly, this is all to the good. A large country, full of natural resources, awaits development, and has has to be developed with very little use of credit. In these circumstances, hard work is necessary, and is likely to bring a great reward. But what will happen when the point has been reached where everybody could be comfortable without working long hours?
-
-In the West, we have various ways of dealing with this problem. We have no attempt at economic justice, so that a large proportion of the total produce goes to a small minority of the population, many of whom do no work at all. Owing to the absence of any central control over production, we produce hosts of things that are not wanted. We keep a large percentage of the working population idle, because we can dispense with their labor by making the others overwork. When all these methods prove inadequate, we have a war: we cause a number of people to manufacture high explosives, and a number of others to explode them, as if we were children who had just discovered fireworks. By a combination of all these devices we manage, though with difficulty, to keep alive the notion that a great deal of severe manual work must be the lot of the average man.
-
-In Russia, owing to more economic justice and central control over production, the problem will have to be differently solved. the rational solution would be, as soon as the necessaries and elementary comforts can be provided for all, to reduce the hours of labor gradually, allowing a popular vote to decide, at each stage, whether more leisure or more goods were to be preferred. But, having taught the supreme virtue of hard work, it is difficult to see how the authorities can aim at a paradise in which there will be much leisure and little work. It seems more likely that they will find continually fresh schemes, by which present leisure is to be sacrificed to future productivity. I read recently of an ingenious plan put forward by Russian engineers, for making the White Sea and the northern coasts of Siberia warm, by putting a dam across the Kara Sea. An admirable project, but liable to postpone proletarian comfort for a generation, while the nobility of toil is being displayed amid the ice-fields and snowstorms of the Arctic Ocean. This sort of thing, if it happens, will be the result of regarding the virtue of hard work as an end in itself, rather than as a means to a state of affairs in which it is no longer needed.
-
-The fact is that moving matter about, while a certain amount of it is necessary to our existence, is emphatically not one of the ends of human life. If it were, we should have to consider every navvy superior to Shakespeare. We have been misled in this matter by two causes. One is the necessity of keeping the poor contented, which has led the rich, for thousands of years, to preach the dignity of labor, while taking care themselves to remain undignified in this respect. The other is the new pleasure in mechanism, which makes us delight in the astonishingly clever changes that we can produce on the earth's surface. Neither of these motives makes any great appeal to the actual worker. If you ask him what he thinks the best part of his life, he is not likely to say: 'I enjoy manual work because it makes me feel that I am fulfilling man's noblest task, and because I like to think how much man can transform his planet. It is true that my body demands periods of rest, which I have to fill in as best I may, but I am never so happy as when the morning comes and I can return to the toil from which my contentment springs.' I have never heard working men say this sort of thing. They consider work, as it should be considered, a necessary means to a livelihood, and it is from their leisure that they derive whatever happiness they may enjoy.
-
-It will be said that, while a little leisure is pleasant, men would not know how to fill their days if they had only four hours of work out of the twenty-four. In so far as this is true in the modern world, it is a condemnation of our civilization; it would not have been true at any earlier period. There was formerly a capacity for light-heartedness and play which has been to some extent inhibited by the cult of efficiency. The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake. Serious-minded persons, for example, are continually condemning the habit of going to the cinema, and telling us that it leads the young into crime. But all the work that goes to producing a cinema is respectable, because it is work, and because it brings a money profit. The notion that the desirable activities are those that bring a profit has made everything topsy-turvy. The butcher who provides you with meat and the baker who provides you with bread are praiseworthy, because they are making money; but when you enjoy the food they have provided, you are merely frivolous, unless you eat only to get strength for your work. Broadly speaking, it is held that getting money is good and spending money is bad. Seeing that they are two sides of one transaction, this is absurd; one might as well maintain that keys are good, but keyholes are bad. Whatever merit there may be in the production of goods must be entirely derivative from the advantage to be obtained by consuming them. The individual, in our society, works for profit; but the social purpose of his work lies in the consumption of what he produces. It is this divorce between the individual and the social purpose of production that makes it so difficult for men to think clearly in a world in which profit-making is the incentive to industry. We think too much of production, and too little of consumption. One result is that we attach too little importance to enjoyment and simple happiness, and that we do not judge production by the pleasure that it gives to the consumer.
-
-When I suggest that working hours should be reduced to four, I am not meaning to imply that all the remaining time should necessarily be spent in pure frivolity. I mean that four hours' work a day should entitle a man to the necessities and elementary comforts of life, and that the rest of his time should be his to use as he might see fit. It is an essential part of any such social system that education should be carried further than it usually is at present, and should aim, in part, at providing tastes which would enable a man to use leisure intelligently. I am not thinking mainly of the sort of things that would be considered 'highbrow'. Peasant dances have died out except in remote rural areas, but the impulses which caused them to be cultivated must still exist in human nature. The pleasures of urban populations have become mainly passive: seeing cinemas, watching football matches, listening to the radio, and so on. This results from the fact that their active energies are fully taken up with work; if they had more leisure, they would again enjoy pleasures in which they took an active part.
-
-In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges. These facts greatly diminished its excellence, but in spite of this drawback it contributed nearly the whole of what we call civilization. It cultivated the arts and discovered the sciences; it wrote the books, invented the philosophies, and refined social relations. Even the liberation of the oppressed has usually been inaugurated from above. Without the leisure class, mankind would never have emerged from barbarism.
-
-The method of a leisure class without duties was, however, extraordinarily wasteful. None of the members of the class had to be taught to be industrious, and the class as a whole was not exceptionally intelligent. The class might produce one Darwin, but against him had to be set tens of thousands of country gentlemen who never thought of anything more intelligent than fox-hunting and punishing poachers. At present, the universities are supposed to provide, in a more systematic way, what the leisure class provided accidentally and as a by-product. This is a great improvement, but it has certain drawbacks. University life is so different from life in the world at large that men who live in academic milieu tend to be unaware of the preoccupations and problems of ordinary men and women; moreover their ways of expressing themselves are usually such as to rob their opinions of the influence that they ought to have upon the general public. Another disadvantage is that in universities studies are organized, and the man who thinks of some original line of research is likely to be discouraged. Academic institutions, therefore, useful as they are, are not adequate guardians of the interests of civilization in a world where everyone outside their walls is too busy for unutilitarian pursuits.
-
-In a world where no one is compelled to work more than four hours a day, every person possessed of scientific curiosity will be able to indulge it, and every painter will be able to paint without starving, however excellent his pictures may be. Young writers will not be obliged to draw attention to themselves by sensational pot-boilers, with a view to acquiring the economic independence needed for monumental works, for which, when the time at last comes, they will have lost the taste and capacity. Men who, in their professional work, have become interested in some phase of economics or government, will be able to develop their ideas without the academic detachment that makes the work of university economists often seem lacking in reality. Medical men will have the time to learn about the progress of medicine, teachers will not be exasperatedly struggling to teach by routine methods things which they learnt in their youth, which may, in the interval, have been proved to be untrue.
-
-Above all, there will be happiness and joy of life, instead of frayed nerves, weariness, and dyspepsia. The work exacted will be enough to make leisure delightful, but not enough to produce exhaustion. Since men will not be tired in their spare time, they will not demand only such amusements as are passive and vapid. At least one per cent will probably devote the time not spent in professional work to pursuits of some public importance, and, since they will not depend upon these pursuits for their livelihood, their originality will be unhampered, and there will be no need to conform to the standards set by elderly pundits. But it is not only in these exceptional cases that the advantages of leisure will appear. Ordinary men and women, having the opportunity of a happy life, will become more kindly and less persecuting and less inclined to view others with suspicion. The taste for war will die out, partly for this reason, and partly because it will involve long and severe work for all. Good nature is, of all moral qualities, the one that the world needs most, and good nature is the result of ease and security, not of a life of arduous struggle. Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish forever.

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+# ipaddr.js — an IPv6 and IPv4 address manipulation library [](https://travis-ci.org/whitequark/ipaddr.js)
+
+ipaddr.js is a small (1.9K minified and gzipped) library for manipulating
+IP addresses in JavaScript environments. It runs on both CommonJS runtimes
+(e.g. [nodejs]) and in a web browser.
+
+ipaddr.js allows you to verify and parse string representation of an IP
+address, match it against a CIDR range or range list, determine if it falls
+into some reserved ranges (examples include loopback and private ranges),
+and convert between IPv4 and IPv4-mapped IPv6 addresses.
+
+[nodejs]: http://nodejs.org
+
+## Installation
+
+`npm install ipaddr.js`
+
+or
+
+`bower install ipaddr.js`
+
+## API
+
+ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS,
+it is exported from the module:
+
+```js
+var ipaddr = require('ipaddr.js');
+```
+
+The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4.
+
+### Global methods
+
+There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and
+`ipaddr.process`. All of them receive a string as a single parameter.
+
+The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or
+IPv6 address, and `false` otherwise. It does not throw any exceptions.
+
+The `ipaddr.parse` method returns an object representing the IP address,
+or throws an `Error` if the passed string is not a valid representation of an
+IP address.
+
+The `ipaddr.process` method works just like the `ipaddr.parse` one, but it
+automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts
+before returning. It is useful when you have a Node.js instance listening
+on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its
+equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4
+connections on your IPv6-only socket, but the remote address will be mangled.
+Use `ipaddr.process` method to automatically demangle it.
+
+### Object representation
+
+Parsing methods return an object which descends from `ipaddr.IPv6` or
+`ipaddr.IPv4`. These objects share some properties, but most of them differ.
+
+#### Shared properties
+
+One can determine the type of address by calling `addr.kind()`. It will return
+either `"ipv6"` or `"ipv4"`.
+
+An address can be converted back to its string representation with `addr.toString()`.
+Note that this method:
+ * does not return the original string used to create the object (in fact, there is
+ no way of getting that string)
+ * returns a compact representation (when it is applicable)
+
+A `match(range, bits)` method can be used to check if the address falls into a
+certain CIDR range.
+Note that an address can be (obviously) matched only against an address of the same type.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:db8:1234::1");
+var range = ipaddr.parse("2001:db8::");
+
+addr.match(range, 32); // => true
+```
+
+Alternatively, `match` can also be called as `match([range, bits])`. In this way,
+it can be used together with the `parseCIDR(string)` method, which parses an IP
+address together with a CIDR range.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:db8:1234::1");
+
+addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true
+```
+
+A `range()` method returns one of predefined names for several special ranges defined
+by IP protocols. The exact names (and their respective CIDR ranges) can be looked up
+in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"`
+(the default one) and `"reserved"`.
+
+You can match against your own range list by using
+`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example:
+
+```js
+var rangeList = {
+ documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ],
+ tunnelProviders: [
+ [ ipaddr.parse('2001:470::'), 32 ], // he.net
+ [ ipaddr.parse('2001:5c0::'), 32 ] // freenet6
+ ]
+};
+ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders"
+```
+
+The addresses can be converted to their byte representation with `toByteArray()`.
+(Actually, JavaScript mostly does not know about byte buffers. They are emulated with
+arrays of numbers, each in range of 0..255.)
+
+```js
+var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com
+bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, <zeroes...>, 0x00, 0x68 ]
+```
+
+The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them
+have the same interface for both protocols, and are similar to global methods.
+
+`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address
+for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser.
+
+`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format.

+[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71
+
+#### IPv6 properties
+
+Sometimes you will want to convert IPv6 not to a compact string representation (with
+the `::` substitution); the `toNormalizedString()` method will return an address where
+all zeroes are explicit.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:0db8::0001");
+addr.toString(); // => "2001:db8::1"
+addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1"
+```
+
+The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped
+one, and `toIPv4Address()` will return an IPv4 object address.
+
+To access the underlying binary representation of the address, use `addr.parts`.
+
+```js
+var addr = ipaddr.parse("2001:db8:10::1234:DEAD");
+addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead]
+```
+
+A IPv6 zone index can be accessed via `addr.zoneId`:
+
+```js
+var addr = ipaddr.parse("2001:db8::%eth0");
+addr.zoneId // => 'eth0'
+```
+
+#### IPv4 properties
+
+`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address.
+
+To access the underlying representation of the address, use `addr.octets`.
+
+```js
+var addr = ipaddr.parse("192.168.1.1");
+addr.octets // => [192, 168, 1, 1]
+```
+
+`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or
+null if the netmask is not valid.
+
+```js
+ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28
+ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask() == null
+```
+
+`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length.
+
+```js
+ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0"
+ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248"
+```
+
+`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation.
+```js
+ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255"
+```
+`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation.
+```js
+ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0"
+```
+
+#### Conversion
+
+IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays.
+
+The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object
+if the input satisfies the requirements. For IPv4 it has to be an array of four 8-bit values,
+while for IPv6 it has to be an array of sixteen 8-bit values.
+
+For example:
+```js
+var addr = ipaddr.fromByteArray([0x7f, 0, 0, 1]);
+addr.toString(); // => "127.0.0.1"
+```
+
+or
+
+```js
+var addr = ipaddr.fromByteArray([0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1])
+addr.toString(); // => "2001:db8::1"
+```
+
+Both objects also offer a `toByteArray()` method, which returns an array in network byte order (MSB).
+
+For example:
+```js
+var addr = ipaddr.parse("127.0.0.1");
+addr.toByteArray(); // => [0x7f, 0, 0, 1]
+```
+
+or
+
+```js
+var addr = ipaddr.parse("2001:db8::1");
+addr.toByteArray(); // => [0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1]
+```

+
+This is a database of all mime types.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+### Database Download
+
+If you're crazy enough to use this in the browser, you can just grab the
+JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
+replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
+as the JSON format may change in the future.
+
+```
+https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
+```
+
+## Usage
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var db = require('mime-db')
+
+// grab data on .js files
+var data = db['application/javascript']
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+ If not set, it's probably a custom media type.
+ - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+ - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+ - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom-types.json` or
+`src/custom-suffix.json`.
+
+The `src/custom-types.json` file is a JSON object with the MIME type as the
+keys and the values being an object with the following keys:
+
+- `compressible` - leave out if you don't know, otherwise `true`/`false` to
+ indicate whether the data represented by the type is typically compressible.
+- `extensions` - include an array of file extensions that are associated with
+ the type.
+- `notes` - human-readable notes about the type, typically what the type is.
+- `sources` - include an array of URLs of where the MIME type and the associated
+ extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
+ links to type aggregating sites and Wikipedia are _not acceptable_.
+
+To update the build, run `npm run build`.
+
+### Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.
+
+If that is not possible / feasible, they can be added directly here as a
+"custom" type. To do this, it is required to have a primary source that
+definitively lists the media type. If an extension is going to be listed as
+associateed with this media type, the source must definitively link the
+media type and extension as well.

+
+The ultimate javascript content-type utility.
+
+Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type,
+ `mime-types` simply returns `false`, so do
+ `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- No `.define()` functionality
+- Bug fixes for `.lookup(path)`
+
+Otherwise, the API is compatible with `mime` 1.x.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+<!-- eslint-disable no-undef -->
+
+```js
+mime.lookup('json') // 'application/json'
+mime.lookup('.md') // 'text/markdown'
+mime.lookup('file.html') // 'text/html'
+mime.lookup('folder/file.js') // 'application/javascript'
+mime.lookup('folder/.htaccess') // false
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+When given an extension, `mime.lookup` is used to get the matching
+content-type, otherwise the given content-type is used. Then if the
+content-type does not already have a `charset` parameter, `mime.charset`
+is used to get the default charset and add to the returned content-type.
+
+<!-- eslint-disable no-undef -->
+
+```js
+mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+mime.contentType('text/html') // 'text/html; charset=utf-8'
+mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
+
+// from a full path
+mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+<!-- eslint-disable no-undef -->
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+<!-- eslint-disable no-undef -->
+
+```js
+mime.charset('text/markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+\r
+## Installation\r
+\r
+```\r
+$ component install component/emitter\r
+```\r
+\r
+## API\r
+\r
+### Emitter(obj)\r
+\r
+ The `Emitter` may also be used as a mixin. For example\r
+ a "plain" object may become an emitter, or you may\r
+ extend an existing prototype.\r
+\r
+ As an `Emitter` instance:\r
+\r
+```js\r
+var Emitter = require('emitter');\r
+var emitter = new Emitter;\r
+emitter.emit('something');\r
+```\r
+\r
+ As a mixin:\r
+\r
+```js\r
+var Emitter = require('emitter');\r
+var user = { name: 'tobi' };\r
+Emitter(user);\r
+\r
+user.emit('im a user');\r
+```\r
+\r
+ As a prototype mixin:\r
+\r
+```js\r
+var Emitter = require('emitter');\r
+Emitter(User.prototype);\r
+```\r
+\r
+### Emitter#on(event, fn)\r
+\r
+ Register an `event` handler `fn`.\r
+\r
+### Emitter#once(event, fn)\r
+\r
+ Register a single-shot `event` handler `fn`,\r
+ removed immediately after it is invoked the\r
+ first time.\r
+\r
+### Emitter#off(event, fn)\r
+\r
+ * Pass `event` and `fn` to remove a listener.\r
+ * Pass `event` to remove all listeners on that event.\r
+ * Pass nothing to remove all listeners on all events.\r
+\r
+### Emitter#emit(event, ...)\r
+\r
+ Emit an `event` with variable option args.\r
+\r
+### Emitter#listeners(event)\r
+\r
+ Return an array of callbacks, or an empty array.\r
+\r
+### Emitter#hasListeners(event)\r
+\r
+ Check if this emitter has `event` handlers.\r

+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

-# Async-Limiter
-
-A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
-
-[](http://www.npmjs.org/async-limiter)
-[](https://travis-ci.org/STRML/async-limiter)
-[](https://coveralls.io/r/STRML/async-limiter)
-
-This module exports a class `Limiter` that implements some of the `Array` API.
-Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
-
-## Motivation
-
-Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
-run at infinite concurrency.
-
-In this case, it is actually faster, and takes far less memory, to limit concurrency.
-
-This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
-make this module faster or lighter, but new functionality is not desired.
-
-Style should confirm to nodejs/node style.
-
-## Example
-
-``` javascript
-var Limiter = require('async-limiter')
-
-var t = new Limiter({concurrency: 2});
-var results = []
-
-// add jobs using the familiar Array API
-t.push(function (cb) {
- results.push('two')
- cb()
-})
-
-t.push(
- function (cb) {
- results.push('four')
- cb()
- },
- function (cb) {
- results.push('five')
- cb()
- }
-)
-
-t.unshift(function (cb) {
- results.push('one')
- cb()
-})
-
-t.splice(2, 0, function (cb) {
- results.push('three')
- cb()
-})
-
-// Jobs run automatically. If you want a callback when all are done,
-// call 'onDone()'.
-t.onDone(function () {
- console.log('all done:', results)
-})
-```
-
-## Zlib Example
-
-```js
-const zlib = require('zlib');
-const Limiter = require('async-limiter');
-
-const message = {some: "data"};
-const payload = new Buffer(JSON.stringify(message));
-
-// Try with different concurrency values to see how this actually
-// slows significantly with higher concurrency!
-//
-// 5: 1398.607ms
-// 10: 1375.668ms
-// Infinity: 4423.300ms
-//
-const t = new Limiter({concurrency: 5});
-function deflate(payload, cb) {
- t.push(function(done) {
- zlib.deflate(payload, function(err, buffer) {
- done();
- cb(err, buffer);
- });
- });
-}
-
-console.time('deflate');
-for(let i = 0; i < 30000; ++i) {
- deflate(payload, function (err, buffer) {});
-}
-t.onDone(function() {
- console.timeEnd('deflate');
-});
-```
-
-## Install
-
-`npm install async-limiter`
-
-## Test
-
-`npm test`
-
-## API
-
-### `var t = new Limiter([opts])`
-Constructor. `opts` may contain inital values for:
-* `t.concurrency`
-
-## Instance methods
-
-### `t.onDone(fn)`
-`fn` will be called once and only once, when the queue is empty.
-
-## Instance methods mixed in from `Array`
-Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
-### `t.push(element1, ..., elementN)`
-### `t.unshift(element1, ..., elementN)`
-### `t.splice(index , howMany[, element1[, ...[, elementN]]])`
-
-## Properties
-### `t.concurrency`
-Max number of jobs the queue should process concurrently, defaults to `Infinity`.
-
-### `t.length`
-Jobs pending + jobs to process (readonly).

-# better-assert
-
- Better c-style assertions using [callsite](https://github.com/visionmedia/callsite) for
- self-documenting failure messages.
-
-## Installation
-
- $ npm install better-assert
-
-## Example
-
- By default assertions are enabled, however the __NO_ASSERT__ environment variable
- will deactivate them when truthy.
-
-```js
-var assert = require('better-assert');
-
-test();
-
-function test() {
- var user = { name: 'tobi' };
- assert('tobi' == user.name);
- assert('number' == typeof user.age);
-}
-
-AssertionError: 'number' == typeof user.age

-
-Basic HTTP cookie parser and serializer for HTTP servers.
-
-## Installation
-
-```sh
-$ npm install cookie
-```
-
-## API
-
-```js
-var cookie = require('cookie');
-```
-
-### cookie.parse(str, options)
-
-Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
-The `str` argument is the string representing a `Cookie` header value and `options` is an
-optional object containing additional parsing options.
-
-```js
-var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
-// { foo: 'bar', equation: 'E=mc^2' }
-```
-
-#### Options
-
-`cookie.parse` accepts these properties in the options object.
-
-##### decode
-
-Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
-has a limited character set (and must be a simple string), this function can be used to decode
-a previously-encoded cookie value into a JavaScript string or other object.
-
-The default function is the global `decodeURIComponent`, which will decode any URL-encoded
-sequences into their byte representations.
-
-**note** if an error is thrown from this function, the original, non-decoded cookie value will
-be returned as the cookie's value.
-
-### cookie.serialize(name, value, options)
-
-Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
-name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
-argument is an optional object containing additional serialization options.
-
-```js
-var setCookie = cookie.serialize('foo', 'bar');
-// foo=bar
-```
-
-#### Options
-
-`cookie.serialize` accepts these properties in the options object.
-
-##### domain
-
-Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6266-5.2.3]. By default, no
-domain is set, and most clients will consider the cookie to apply to only the current domain.
-
-##### encode
-
-Specifies a function that will be used to encode a cookie's value. Since value of a cookie
-has a limited character set (and must be a simple string), this function can be used to encode
-a value into a string suited for a cookie's value.
-
-The default function is the global `ecodeURIComponent`, which will encode a JavaScript string
-into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
-
-##### expires
-
-Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6266-5.2.1].
-By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
-will delete it on a condition like exiting a web browser application.
-
-**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
-`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
-so if both are set, they should point to the same date and time.
-
-##### httpOnly
-
-Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6266-5.2.6]. When truthy,
-the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
-
-**note** be careful when setting this to `true`, as compliant clients will not allow client-side
-JavaScript to see the cookie in `document.cookie`.
-
-##### maxAge
-
-Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6266-5.2.2].
-The given number will be converted to an integer by rounding down. By default, no maximum age is set.
-
-**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
-`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
-so if both are set, they should point to the same date and time.
-
-##### path
-
-Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6266-5.2.4]. By default, the path
-is considered the ["default path"][rfc-6266-5.1.4]. By default, no maximum age is set, and most
-clients will consider this a "non-persistent cookie" and will delete it on a condition like exiting
-a web browser application.
-
-##### sameSite
-
-Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][draft-west-first-party-cookies-07].
-
- - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
- - `false` will not set the `SameSite` attribute.
- - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
- - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
-
-More information about the different enforcement levels can be found in the specification
-https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-4.1.1
-
-**note** This is an attribute that has not yet been fully standardized, and may change in the future.
-This also means many clients may ignore this attribute until they understand it.
-
-##### secure
-
-Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6266-5.2.5]. When truthy,
-the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
-
-**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
-the server in the future if the browser does not have an HTTPS connection.
-
-## Example
-
-The following example uses this module in conjunction with the Node.js core HTTP server
-to prompt a user for their name and display it back on future visits.
-
-```js
-var cookie = require('cookie');
-var escapeHtml = require('escape-html');
-var http = require('http');
-var url = require('url');
-
-function onRequest(req, res) {
- // Parse the query string
- var query = url.parse(req.url, true, true).query;
-
- if (query && query.name) {
- // Set a new cookie with the name
- res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
- httpOnly: true,
- maxAge: 60 * 60 * 24 * 7 // 1 week
- }));
-
- // Redirect back after setting cookie
- res.statusCode = 302;
- res.setHeader('Location', req.headers.referer || '/');
- res.end();
- return;
- }
-
- // Parse the cookies on the request
- var cookies = cookie.parse(req.headers.cookie || '');
-
- // Get the visitor name set in the cookie
- var name = cookies.name;
-
- res.setHeader('Content-Type', 'text/html; charset=UTF-8');
-
- if (name) {
- res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
- } else {
- res.write('<p>Hello, new visitor!</p>');
- }
-
- res.write('<form method="GET">');
- res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
- res.end('</form');
-}
-
-http.createServer(onRequest).listen(3000);
-```

-# Engine.IO client
-
-[](http://travis-ci.org/socketio/engine.io-client)
-[](http://badge.fury.io/js/engine.io-client)
-
-This is the client for [Engine.IO](http://github.com/socketio/engine.io),
-the implementation of transport-based cross-browser/cross-device
-bi-directional communication layer for [Socket.IO](http://github.com/socketio/socket.io).
-
-## How to use
-
-### Standalone
-
-You can find an `engine.io.js` file in this repository, which is a
-standalone build you can use as follows:
-
-```html
-<script src="/path/to/engine.io.js"></script>
-<script>
- // eio = Socket
- var socket = eio('ws://localhost');
- socket.on('open', function(){
- socket.on('message', function(data){});
- socket.on('close', function(){});
- });
-</script>
-```
-
-### With browserify
-
-Engine.IO is a commonjs module, which means you can include it by using
-`require` on the browser and package using [browserify](http://browserify.org/):
-
-1. install the client package
-
- ```bash
- $ npm install engine.io-client
- ```
-
-1. write your app code
-
- ```js
- var socket = require('engine.io-client')('ws://localhost');
- socket.on('open', function(){
- socket.on('message', function(data){});
- socket.on('close', function(){});
- });
- ```
-
-1. build your app bundle
-
- ```bash
- $ browserify app.js > bundle.js
- ```
-
-1. include on your page
-
- ```html
- <script src="/path/to/bundle.js"></script>
- ```
-
-### Sending and receiving binary
-
-```html
-<script src="/path/to/engine.io.js"></script>
-<script>
- var socket = new eio.Socket('ws://localhost/');
- socket.binaryType = 'blob';
- socket.on('open', function () {
- socket.send(new Int8Array(5));
- socket.on('message', function(blob){});
- socket.on('close', function(){ });
- });
-</script>
-```
-
-### Node.JS
-
-Add `engine.io-client` to your `package.json` and then:
-
-```js
-var socket = require('engine.io-client')('ws://localhost');
-socket.on('open', function(){
- socket.on('message', function(data){});
- socket.on('close', function(){});
-});
-```
-
-### Node.js with certificates
-```js
-var opts = {
- key: fs.readFileSync('test/fixtures/client.key'),
- cert: fs.readFileSync('test/fixtures/client.crt'),
- ca: fs.readFileSync('test/fixtures/ca.crt')
-};
-
-var socket = require('engine.io-client')('ws://localhost', opts);
-socket.on('open', function(){
- socket.on('message', function(data){});
- socket.on('close', function(){});
-});
-```
-
-### Node.js with extraHeaders
-```js
-var opts = {
- extraHeaders: {
- 'X-Custom-Header-For-My-Project': 'my-secret-access-token',
- 'Cookie': 'user_session=NI2JlCKF90aE0sJZD9ZzujtdsUqNYSBYxzlTsvdSUe35ZzdtVRGqYFr0kdGxbfc5gUOkR9RGp20GVKza; path=/; expires=Tue, 07-Apr-2015 18:18:08 GMT; secure; HttpOnly'
- }
-};
-
-var socket = require('engine.io-client')('ws://localhost', opts);
-socket.on('open', function(){
- socket.on('message', function(data){});
- socket.on('close', function(){});
-});
-```
-
-## Features
-
-- Lightweight
-- Runs on browser and node.js seamlessly
-- Transports are independent of `Engine`
- - Easy to debug
- - Easy to unit test
-- Runs inside HTML5 WebWorker
-- Can send and receive binary data
- - Receives as ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer
- in Node
- - When XHR2 or WebSockets are used, binary is emitted directly. Otherwise
- binary is encoded into base64 strings, and decoded when binary types are
- supported.
- - With browsers that don't support ArrayBuffer, an object { base64: true,
- data: dataAsBase64String } is emitted on the `message` event.
-
-## API
-
-### Socket
-
-The client class. Mixes in [Emitter](http://github.com/component/emitter).
-Exposed as `eio` in the browser standalone build.
-
-#### Properties
-
-- `protocol` _(Number)_: protocol revision number
-- `binaryType` _(String)_ : can be set to 'arraybuffer' or 'blob' in browsers,
- and `buffer` or `arraybuffer` in Node. Blob is only used in browser if it's
- supported.
-
-#### Events
-
-- `open`
- - Fired upon successful connection.
-- `message`
- - Fired when data is received from the server.
- - **Arguments**
- - `String` | `ArrayBuffer`: utf-8 encoded data or ArrayBuffer containing
- binary data
-- `close`
- - Fired upon disconnection. In compliance with the WebSocket API spec, this event may be
- fired even if the `open` event does not occur (i.e. due to connection error or `close()`).
-- `error`
- - Fired when an error occurs.
-- `flush`
- - Fired upon completing a buffer flush
-- `drain`
- - Fired after `drain` event of transport if writeBuffer is empty
-- `upgradeError`
- - Fired if an error occurs with a transport we're trying to upgrade to.
-- `upgrade`
- - Fired upon upgrade success, after the new transport is set
-- `ping`
- - Fired upon _flushing_ a ping packet (ie: actual packet write out)
-- `pong`
- - Fired upon receiving a pong packet.
-
-#### Methods
-
-- **constructor**
- - Initializes the client
- - **Parameters**
- - `String` uri
- - `Object`: optional, options object
- - **Options**
- - `agent` (`http.Agent`): `http.Agent` to use, defaults to `false` (NodeJS only)
- - `upgrade` (`Boolean`): defaults to true, whether the client should try
- to upgrade the transport from long-polling to something better.
- - `forceJSONP` (`Boolean`): forces JSONP for polling transport.
- - `jsonp` (`Boolean`): determines whether to use JSONP when
- necessary for polling. If disabled (by settings to false) an error will
- be emitted (saying "No transports available") if no other transports
- are available. If another transport is available for opening a
- connection (e.g. WebSocket) that transport
- will be used instead.
- - `forceBase64` (`Boolean`): forces base 64 encoding for polling transport even when XHR2 responseType is available and WebSocket even if the used standard supports binary.
- - `enablesXDR` (`Boolean`): enables XDomainRequest for IE8 to avoid loading bar flashing with click sound. default to `false` because XDomainRequest has a flaw of not sending cookie.
- - `withCredentials` (`Boolean`): defaults to `true`, whether to include credentials (cookies, authorization headers, TLS client certificates, etc.) with cross-origin XHR polling requests.
- - `timestampRequests` (`Boolean`): whether to add the timestamp with each
- transport request. Note: polling requests are always stamped unless this
- option is explicitly set to `false` (`false`)
- - `timestampParam` (`String`): timestamp parameter (`t`)
- - `policyPort` (`Number`): port the policy server listens on (`843`)
- - `path` (`String`): path to connect to, default is `/engine.io`
- - `transports` (`Array`): a list of transports to try (in order).
- Defaults to `['polling', 'websocket']`. `Engine`
- always attempts to connect directly with the first one, provided the
- feature detection test for it passes.
- - `transportOptions` (`Object`): hash of options, indexed by transport name, overriding the common options for the given transport
- - `rememberUpgrade` (`Boolean`): defaults to false.
- If true and if the previous websocket connection to the server succeeded,
- the connection attempt will bypass the normal upgrade process and will initially
- try websocket. A connection attempt following a transport error will use the
- normal upgrade process. It is recommended you turn this on only when using
- SSL/TLS connections, or if you know that your network does not block websockets.
- - `pfx` (`String`|`Buffer`): Certificate, Private key and CA certificates to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
- - `key` (`String`): Private key to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
- - `passphrase` (`String`): A string of passphrase for the private key or pfx. Can be used in Node.js client environment to manually specify certificate information.
- - `cert` (`String`): Public x509 certificate to use. Can be used in Node.js client environment to manually specify certificate information.
- - `ca` (`String`|`Array`): An authority certificate or array of authority certificates to check the remote host against.. Can be used in Node.js client environment to manually specify certificate information.
- - `ciphers` (`String`): A string describing the ciphers to use or exclude. Consult the [cipher format list](http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT) for details on the format. Can be used in Node.js client environment to manually specify certificate information.
- - `rejectUnauthorized` (`Boolean`): If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Can be used in Node.js client environment to manually specify certificate information.
- - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
- (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
- - `threshold` (`Number`): data is compressed only if the byte size is above this value. This option is ignored on the browser. (`1024`)
- - `extraHeaders` (`Object`): Headers that will be passed for each request to the server (via xhr-polling and via websockets). These values then can be used during handshake or for special proxies. Can only be used in Node.js client environment.
- - `onlyBinaryUpgrades` (`Boolean`): whether transport upgrades should be restricted to transports supporting binary data (`false`)
- - `forceNode` (`Boolean`): Uses NodeJS implementation for websockets - even if there is a native Browser-Websocket available, which is preferred by default over the NodeJS implementation. (This is useful when using hybrid platforms like nw.js or electron) (`false`, NodeJS only)
- - `localAddress` (`String`): the local IP address to connect to
- - **Polling-only options**
- - `requestTimeout` (`Number`): Timeout for xhr-polling requests in milliseconds (`0`)
- - **Websocket-only options**
- - `protocols` (`Array`): a list of subprotocols (see [MDN reference](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols))
-- `send`
- - Sends a message to the server
- - **Parameters**
- - `String` | `ArrayBuffer` | `ArrayBufferView` | `Blob`: data to send
- - `Object`: optional, options object
- - `Function`: optional, callback upon `drain`
- - **Options**
- - `compress` (`Boolean`): whether to compress sending data. This option is ignored and forced to be `true` on the browser. (`true`)
-- `close`
- - Disconnects the client.
-
-### Transport
-
-The transport class. Private. _Inherits from EventEmitter_.
-
-#### Events
-
-- `poll`: emitted by polling transports upon starting a new request
-- `pollComplete`: emitted by polling transports upon completing a request
-- `drain`: emitted by polling transports upon a buffer drain
-
-## Tests
-
-`engine.io-client` is used to test
-[engine](http://github.com/socketio/engine.io). Running the `engine.io`
-test suite ensures the client works and vice-versa.
-
-Browser tests are run using [zuul](https://github.com/defunctzombie/zuul). You can
-run the tests locally using the following command.
-
-```
-./node_modules/.bin/zuul --local 8080 -- test/index.js
-```
-
-Additionally, `engine.io-client` has a standalone test suite you can run
-with `make test` which will run node.js and browser tests. You must have zuul setup with
-a saucelabs account.
-
-## Support
-
-The support channels for `engine.io-client` are the same as `socket.io`:
- - irc.freenode.net **#socket.io**
- - [Google Groups](http://groups.google.com/group/socket_io)
- - [Website](http://socket.io)
-
-## Development
-
-To contribute patches, run tests or benchmarks, make sure to clone the
-repository:
-
-```bash
-git clone git://github.com/socketio/engine.io-client.git
-```
-
-Then:
-
-```bash
-cd engine.io-client
-npm install
-```
-
-See the `Tests` section above for how to run tests before submitting any patches.

-# ws: a Node.js WebSocket library
-
-[](https://www.npmjs.com/package/ws)
-[](https://travis-ci.org/websockets/ws)
-[](https://ci.appveyor.com/project/lpinca/ws)
-[](https://coveralls.io/r/websockets/ws?branch=master)
-
-ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
-server implementation.
-
-Passes the quite extensive Autobahn test suite: [server][server-report],
-[client][client-report].
-
-**Note**: This module does not work in the browser. The client in the docs is a
-reference to a back end with the role of a client in the WebSocket
-communication. Browser clients must use the native
-[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
-object. To make the same code work seamlessly on Node.js and the browser, you
-can use one of the many wrappers available on npm, like
-[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

-## Protocol support
-
-- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
-- **HyBi drafts 13-17** (Current default, alternatively option
- `protocolVersion: 13`)
-
-## Installing
-
-```
-npm install ws
-```
-
-### Opt-in for performance and spec compliance
-
-There are 2 optional modules that can be installed along side with the ws
-module. These modules are binary addons which improve certain operations.
-Prebuilt binaries are available for the most popular platforms so you don't
-necessarily need to have a C++ compiler installed on your machine.
-
-- `npm install --save-optional bufferutil`: Allows to efficiently perform
- operations such as masking and unmasking the data payload of the WebSocket
- frames.
-- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
- message contains valid UTF-8 as required by the spec.
-
-## API docs
-
-See [`/doc/ws.md`](./doc/ws.md) for Node.js-like docs for the ws classes.
-
-## WebSocket compression
-
-ws supports the [permessage-deflate extension][permessage-deflate] which enables
-the client and server to negotiate a compression algorithm and its parameters,
-and then selectively apply it to the data payloads of each WebSocket message.
-
-The extension is disabled by default on the server and enabled by default on the
-client. It adds a significant overhead in terms of performance and memory
-consumption so we suggest to enable it only if it is really needed.
-
-Note that Node.js has a variety of issues with high-performance compression,
-where increased concurrency, especially on Linux, can lead to [catastrophic
-memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
-permessage-deflate in production, it is worthwhile to set up a test
-representative of your workload and ensure Node.js/zlib will handle it with
-acceptable performance and memory usage.
-
-Tuning of permessage-deflate can be done via the options defined below. You can
-also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
-into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
-
-See [the docs][ws-server-options] for more options.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({
- port: 8080,
- perMessageDeflate: {
- zlibDeflateOptions: {
- // See zlib defaults.
- chunkSize: 1024,
- memLevel: 7,
- level: 3
- },
- zlibInflateOptions: {
- chunkSize: 10 * 1024
- },
- // Other options settable:
- clientNoContextTakeover: true, // Defaults to negotiated value.
- serverNoContextTakeover: true, // Defaults to negotiated value.
- serverMaxWindowBits: 10, // Defaults to negotiated value.
- // Below options specified as default values.
- concurrencyLimit: 10, // Limits zlib concurrency for perf.
- threshold: 1024 // Size (in bytes) below which messages
- // should not be compressed.
- }
-});
-```
-
-The client will only use the extension if it is supported and enabled on the
-server. To always disable the extension on the client set the
-`perMessageDeflate` option to `false`.
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path', {
- perMessageDeflate: false
-});
-```
-
-## Usage examples
-
-### Sending and receiving text data
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path');
-
-ws.on('open', function open() {
- ws.send('something');
-});
-
-ws.on('message', function incoming(data) {
- console.log(data);
-});
-```
-
-### Sending binary data
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path');
-
-ws.on('open', function open() {
- const array = new Float32Array(5);
-
- for (var i = 0; i < array.length; ++i) {
- array[i] = i / 2;
- }
-
- ws.send(array);
-});
-```
-
-### Simple server
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws) {
- ws.on('message', function incoming(message) {
- console.log('received: %s', message);
- });
-
- ws.send('something');
-});
-```
-
-### External HTTP/S server
-
-```js
-const fs = require('fs');
-const https = require('https');
-const WebSocket = require('ws');
-
-const server = new https.createServer({
- cert: fs.readFileSync('/path/to/cert.pem'),
- key: fs.readFileSync('/path/to/key.pem')
-});
-const wss = new WebSocket.Server({ server });
-
-wss.on('connection', function connection(ws) {
- ws.on('message', function incoming(message) {
- console.log('received: %s', message);
- });
-
- ws.send('something');
-});
-
-server.listen(8080);
-```
-
-### Multiple servers sharing a single HTTP/S server
-
-```js
-const http = require('http');
-const WebSocket = require('ws');
-
-const server = http.createServer();
-const wss1 = new WebSocket.Server({ noServer: true });
-const wss2 = new WebSocket.Server({ noServer: true });
-
-wss1.on('connection', function connection(ws) {
- // ...
-});
-
-wss2.on('connection', function connection(ws) {
- // ...
-});
-
-server.on('upgrade', function upgrade(request, socket, head) {
- const pathname = url.parse(request.url).pathname;
-
- if (pathname === '/foo') {
- wss1.handleUpgrade(request, socket, head, function done(ws) {
- wss1.emit('connection', ws, request);
- });
- } else if (pathname === '/bar') {
- wss2.handleUpgrade(request, socket, head, function done(ws) {
- wss2.emit('connection', ws, request);
- });
- } else {
- socket.destroy();
- }
-});
-
-server.listen(8080);
-```
-
-### Server broadcast
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-// Broadcast to all.
-wss.broadcast = function broadcast(data) {
- wss.clients.forEach(function each(client) {
- if (client.readyState === WebSocket.OPEN) {
- client.send(data);
- }
- });
-};
-
-wss.on('connection', function connection(ws) {
- ws.on('message', function incoming(data) {
- // Broadcast to everyone else.
- wss.clients.forEach(function each(client) {
- if (client !== ws && client.readyState === WebSocket.OPEN) {
- client.send(data);
- }
- });
- });
-});
-```
-
-### echo.websocket.org demo

-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('wss://echo.websocket.org/', {
- origin: 'https://websocket.org'
-});
-
-ws.on('open', function open() {

-For a full example with a browser client communicating with a ws server, see the
-examples folder.

-Otherwise, see the test cases.
-
-## Error handling best practices
-
-```js
-// If the WebSocket is closed before the following send is attempted
-ws.send('something');
-
-// Errors (both immediate and async write errors) can be detected in an optional
-// callback. The callback is also the only way of being notified that data has
-// actually been sent.
-ws.send('something', function ack(error) {
- // If error is not defined, the send has been completed, otherwise the error
- // object will indicate what failed.
-});
-
-// Immediate errors can also be handled with `try...catch`, but **note** that
-// since sends are inherently asynchronous, socket write failures will *not* be
-// captured when this technique is used.
-try {
- ws.send('something');
-} catch (e) {
- /* handle error */
-}
-```
-
-## FAQ
-
-### How to get the IP address of the client?
-
-The remote IP address can be obtained from the raw socket.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws, req) {
- const ip = req.connection.remoteAddress;
-});
-```
-
-When the server runs behind a proxy like NGINX, the de-facto standard is to use
-the `X-Forwarded-For` header.
-
-```js
-wss.on('connection', function connection(ws, req) {
- const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
-});
-```
-
-### How to detect and close broken connections?
-
-Sometimes the link between the server and the client can be interrupted in a way
-that keeps both the server and the client unaware of the broken state of the
-connection (e.g. when pulling the cord).
-
-In these cases ping messages can be used as a means to verify that the remote
-endpoint is still responsive.
-
-```js
-const WebSocket = require('ws');
-
-function noop() {}
-
-function heartbeat() {
- this.isAlive = true;
-}
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws) {
- ws.isAlive = true;
- ws.on('pong', heartbeat);
-});
-
-const interval = setInterval(function ping() {
- wss.clients.forEach(function each(ws) {
- if (ws.isAlive === false) return ws.terminate();
-
- ws.isAlive = false;
- ws.ping(noop);
- });
-}, 30000);
-```
-
-Pong messages are automatically sent in response to ping messages as required by
-the spec.
-
-Just like the server example above your clients might as well lose connection
-without knowing it. You might want to add a ping listener on your clients to
-prevent that. A simple implementation would be:
-
-```js
-const WebSocket = require('ws');
-
-function heartbeat() {
- clearTimeout(this.pingTimeout);
-
- // Use `WebSocket#terminate()` and not `WebSocket#close()`. Delay should be
- // equal to the interval at which your server sends out pings plus a
- // conservative assumption of the latency.
- this.pingTimeout = setTimeout(() => {
- this.terminate();
- }, 30000 + 1000);
-}
-
-const client = new WebSocket('wss://echo.websocket.org/');
-
-client.on('open', heartbeat);
-client.on('ping', heartbeat);
-client.on('close', function clear() {
- clearTimeout(this.pingTimeout);
-});
-```
-
-### How to connect via a proxy?
-
-Use a custom `http.Agent` implementation like [https-proxy-agent][] or
-[socks-proxy-agent][].

-# Engine.IO: the realtime engine
-
-[](http://travis-ci.org/socketio/engine.io)
-[](http://badge.fury.io/js/engine.io)
-
-`Engine.IO` is the implementation of transport-based
-cross-browser/cross-device bi-directional communication layer for
-[Socket.IO](http://github.com/socketio/socket.io).
-
-## How to use
-
-### Server
-
-#### (A) Listening on a port
-
-```js
-var engine = require('engine.io');
-var server = engine.listen(80);
-
-server.on('connection', function(socket){
- socket.send('utf 8 string');
- socket.send(Buffer.from([0, 1, 2, 3, 4, 5])); // binary data
-});
-```
-
-#### (B) Intercepting requests for a http.Server
-
-```js
-var engine = require('engine.io');
-var http = require('http').createServer().listen(3000);
-var server = engine.attach(http);
-
-server.on('connection', function (socket) {
- socket.on('message', function(data){ });
- socket.on('close', function(){ });
-});
-```
-
-#### (C) Passing in requests
-
-```js
-var engine = require('engine.io');
-var server = new engine.Server();
-
-server.on('connection', function(socket){
- socket.send('hi');
-});
-
-// …
-httpServer.on('upgrade', function(req, socket, head){
- server.handleUpgrade(req, socket, head);
-});
-httpServer.on('request', function(req, res){
- server.handleRequest(req, res);
-});
-```
-
-### Client
-
-```html
-<script src="/path/to/engine.io.js"></script>
-<script>
- var socket = new eio.Socket('ws://localhost/');
- socket.on('open', function(){
- socket.on('message', function(data){});
- socket.on('close', function(){});
- });
-</script>
-```
-
-For more information on the client refer to the
-[engine-client](http://github.com/learnboost/engine.io-client) repository.
-
-## What features does it have?
-
-- **Maximum reliability**. Connections are established even in the presence of:
- - proxies and load balancers.
- - personal firewall and antivirus software.
- - for more information refer to **Goals** and **Architecture** sections
-- **Minimal client size** aided by:
- - lazy loading of flash transports.
- - lack of redundant transports.
-- **Scalable**
- - load balancer friendly
-- **Future proof**
-- **100% Node.JS core style**
- - No API sugar (left for higher level projects)
- - Written in readable vanilla JavaScript
-
-## API
-
-### Server
-
-<hr><br>
-
-#### Top-level
-
-These are exposed by `require('engine.io')`:
-
-##### Events
-
-- `flush`
- - Called when a socket buffer is being flushed.
- - **Arguments**
- - `Socket`: socket being flushed
- - `Array`: write buffer
-- `drain`
- - Called when a socket buffer is drained
- - **Arguments**
- - `Socket`: socket being flushed
-
-##### Properties
-
-- `protocol` _(Number)_: protocol revision number
-- `Server`: Server class constructor
-- `Socket`: Socket class constructor
-- `Transport` _(Function)_: transport constructor
-- `transports` _(Object)_: map of available transports
-
-##### Methods
-
-- `()`
- - Returns a new `Server` instance. If the first argument is an `http.Server` then the
- new `Server` instance will be attached to it. Otherwise, the arguments are passed
- directly to the `Server` constructor.
- - **Parameters**
- - `http.Server`: optional, server to attach to.
- - `Object`: optional, options object (see `Server#constructor` api docs below)
-
- The following are identical ways to instantiate a server and then attach it.
-
-```js
-var httpServer; // previously created with `http.createServer();` from node.js api.
-
-// create a server first, and then attach
-var eioServer = require('engine.io').Server();
-eioServer.attach(httpServer);
-
-// or call the module as a function to get `Server`
-var eioServer = require('engine.io')();
-eioServer.attach(httpServer);
-
-// immediately attach
-var eioServer = require('engine.io')(httpServer);
-
-// with custom options
-var eioServer = require('engine.io')(httpServer, {
- maxHttpBufferSize: 1e3
-});
-```
-
-- `listen`
- - Creates an `http.Server` which listens on the given port and attaches WS
- to it. It returns `501 Not Implemented` for regular http requests.
- - **Parameters**
- - `Number`: port to listen on.
- - `Object`: optional, options object
- - `Function`: callback for `listen`.
- - **Options**
- - All options from `Server.attach` method, documented below.
- - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
- - **Returns** `Server`
-
-```js
-var engine = require('engine.io');
-var server = engine.listen(3000, {
- pingTimeout: 2000,
- pingInterval: 10000
-});
-
-server.on('connection', /* ... */);
-```
-
-- `attach`
- - Captures `upgrade` requests for a `http.Server`. In other words, makes
- a regular http.Server WebSocket-compatible.
- - **Parameters**
- - `http.Server`: server to attach to.
- - `Object`: optional, options object
- - **Options**
- - All options from `Server.attach` method, documented below.
- - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
- - **Returns** `Server` a new Server instance.
-
-```js
-var engine = require('engine.io');
-var httpServer = require('http').createServer().listen(3000);
-var server = engine.attach(httpServer, {
- wsEngine: 'uws' // requires having uws as dependency
-});
-
-server.on('connection', /* ... */);
-```
-
-#### Server
-
-The main server/manager. _Inherits from EventEmitter_.

-**Important**: if you plan to use Engine.IO in a scalable way, please
-keep in mind the properties below will only reflect the clients connected
-to a single process.
-
-- `clients` _(Object)_: hash of connected clients by id.
-- `clientsCount` _(Number)_: number of connected clients.
-
-##### Methods
-
-- **constructor**
- - Initializes the server
- - **Parameters**
- - `Object`: optional, options object
- - **Options**
- - `pingTimeout` (`Number`): how many ms without a pong packet to
- consider the connection closed (`5000`)
- - `pingInterval` (`Number`): how many ms before sending a new ping
- packet (`25000`)
- - `upgradeTimeout` (`Number`): how many ms before an uncompleted transport upgrade is cancelled (`10000`)
- - `maxHttpBufferSize` (`Number`): how many bytes or characters a message
- can be, before closing the session (to avoid DoS). Default
- value is `10E7`.
- - `allowRequest` (`Function`): A function that receives a given handshake
- or upgrade request as its first parameter, and can decide whether to
- continue or not. The second argument is a function that needs to be
- called with the decided information: `fn(err, success)`, where
- `success` is a boolean value where false means that the request is
- rejected, and err is an error code.
- - `transports` (`<Array> String`): transports to allow connections
- to (`['polling', 'websocket']`)
- - `allowUpgrades` (`Boolean`): whether to allow transport upgrades
- (`true`)
- - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
- (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)

- - `Object`: optional, options object
- - **Options**
- - `path` (`String`): name of the path to capture (`/engine.io`).
- - `destroyUpgrade` (`Boolean`): destroy unhandled upgrade requests (`true`)
- - `destroyUpgradeTimeout` (`Number`): milliseconds after which unhandled requests are ended (`1000`)
- - `handlePreflightRequest` (`Boolean|Function`): whether to let engine.io handle the OPTIONS requests. You can also pass a custom function to handle the requests (`true`)
-- `generateId`
- - Generate a socket id.
- - Overwrite this method to generate your custom socket id.

-### Client
-
-<hr><br>
-
-Exposed in the `eio` global namespace (in the browser), or by
-`require('engine.io-client')` (in Node.JS).
-
-For the client API refer to the
-[engine-client](http://github.com/learnboost/engine.io-client) repository.
-
-## Debug / logging
-
-Engine.IO is powered by [debug](http://github.com/visionmedia/debug).
-In order to see all the debug output, run your app with the environment variable
-`DEBUG` including the desired scope.
-
-To see the output from all of Engine.IO's debugging scopes you can use:
-
-```
-DEBUG=engine* node myapp
-```
-
-## Transports
-
-- `polling`: XHR / JSONP polling transport.
-- `websocket`: WebSocket transport.
-
-## Plugins
-
-- [engine.io-conflation](https://github.com/EugenDueck/engine.io-conflation): Makes **conflation and aggregation** of messages straightforward.
-
-## Support
-
-The support channels for `engine.io` are the same as `socket.io`:
- - irc.freenode.net **#socket.io**
- - [Google Groups](http://groups.google.com/group/socket_io)
- - [Website](http://socket.io)
-
-## Development
-
-To contribute patches, run tests or benchmarks, make sure to clone the
-repository:
-
-```
-git clone git://github.com/LearnBoost/engine.io.git
-```
-
-Then:
-
-```
-cd engine.io
-npm install
-```
-
-## Tests
-
-Tests run with `npm test`. It runs the server tests that are aided by
-the usage of `engine.io-client`.
-
-Make sure `npm install` is run first.
-
-## Goals
-
-The main goal of `Engine` is ensuring the most reliable realtime communication.
-Unlike the previous Socket.IO core, it always establishes a long-polling
-connection first, then tries to upgrade to better transports that are "tested" on
-the side.
-
-During the lifetime of the Socket.IO projects, we've found countless drawbacks
-to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
-mechanisms.
-
-Both are clearly the _right way_ of establishing a bidirectional communication,
-with HTML5 WebSocket being the way of the future. However, to answer most business
-needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
-the same solution.
-
-WebSocket based connections have two fundamental benefits:
-
-1. **Better server performance**
- - _A: Load balancers_<br>
- Load balancing a long polling connection poses a serious architectural nightmare
- since requests can come from any number of open sockets by the user agent, but
- they all need to be routed to the process and computer that owns the `Engine`
- connection. This negatively impacts RAM and CPU usage.
- - _B: Network traffic_<br>
- WebSocket is designed around the premise that each message frame has to be
- surrounded by the least amount of data. In HTTP 1.1 transports, each message
- frame is surrounded by HTTP headers and chunked encoding frames. If you try to
- send the message _"Hello world"_ with xhr-polling, the message ultimately
- becomes larger than if you were to send it with WebSocket.
- - _C: Lightweight parser_<br>
- As an effect of **B**, the server has to do a lot more work to parse the network
- data and figure out the message when traditional HTTP requests are used
- (as in long polling). This means that another advantage of WebSocket is
- less server CPU usage.
-
-2. **Better user experience**
-
- Due to the reasons stated in point **1**, the most important effect of being able
- to establish a WebSocket connection is raw data transfer speed, which translates
- in _some_ cases in better user experience.
-
- Applications with heavy realtime interaction (such as games) will benefit greatly,
- whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
- timelines (Twitter) will have negligible user experience improvements.
-
-Having said this, attempting to establish a WebSocket connection directly so far has
-proven problematic:
-
-1. **Proxies**<br>
- Many corporate proxies block WebSocket traffic.
-
-2. **Personal firewall and antivirus software**<br>
- As a result of our research, we've found that at least 3 personal security
- applications block WebSocket traffic.
-
-3. **Cloud application platforms**<br>
- Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
- nature of the evolution of the WebSocket protocol. Applications therefore end up
- inevitably using long polling, but the seamless installation experience of
- Socket.IO we strive for (_"require() it and it just works"_) disappears.
-
-Some of these problems have solutions. In the case of proxies and personal programs,
-however, the solutions many times involve upgrading software. Experience has shown
-that relying on client software upgrades to deliver a business solution is
-fruitless: the very existence of this project has to do with a fragmented panorama
-of user agent distribution, with clients connecting with latest versions of the most
-modern user agents (Chrome, Firefox and Safari), but others with versions as low as
-IE 5.5.
-
-From the user perspective, an unsuccessful WebSocket connection can translate in
-up to at least 10 seconds of waiting for the realtime application to begin
-exchanging data. This **perceptively** hurts user experience.
-
-To summarize, **Engine** focuses on reliability and user experience first, marginal
-potential UX improvements and increased server performance second. `Engine` is the
-result of all the lessons learned with WebSocket in the wild.
-
-## Architecture
-
-The main premise of `Engine`, and the core of its existence, is the ability to
-swap transports on the fly. A connection starts as xhr-polling, but it can
-switch to WebSocket.
-
-The central problem this poses is: how do we switch transports without losing
-messages?
-
-`Engine` only switches from polling to another transport in between polling
-cycles. Since the server closes the connection after a certain timeout when
-there's no activity, and the polling transport implementation buffers messages
-in between connections, this ensures no message loss and optimal performance.
-
-Another benefit of this design is that we workaround almost all the limitations
-of **Flash Socket**, such as slow connection times, increased file size (we can
-safely lazy load it without hurting user experience), etc.

-### Can I use engine without Socket.IO ?
-
-Absolutely. Although the recommended framework for building realtime applications
-is Socket.IO, since it provides fundamental features for real-world applications
-such as multiplexing, reconnection support, etc.
-
-`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
-realtime frameworks, but something you _probably_ won't be using for building
-actual applications.
-
-### Does the server serve the client?
-
-No. The main reason is that `Engine` is meant to be bundled with frameworks.
-Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
-you use Socket.IO, including
-
-```html
-<script src="/socket.io/socket.io.js">
-```
-
-has you covered.
-
-### Can I implement `Engine` in other languages?
-
-Absolutely. The [engine.io-protocol](https://github.com/LearnBoost/engine.io-protocol)
-repository contains the most up to date description of the specification
-at all times, and the parser implementation in JavaScript.

-
-This is a database of all mime types.
-It consists of a single, public JSON file and does not include any logic,
-allowing it to remain as un-opinionated as possible with an API.
-It aggregates data from the following sources:
-
-- http://www.iana.org/assignments/media-types/media-types.xhtml
-- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
-- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
-
-## Installation
-
-```bash
-npm install mime-db
-```
-
-### Database Download
-
-If you're crazy enough to use this in the browser, you can just grab the
-JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
-replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
-as the JSON format may change in the future.
-
-```
-https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
-```
-
-## Usage
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var db = require('mime-db')
-
-// grab data on .js files
-var data = db['application/javascript']
-```
-
-## Data Structure
-
-The JSON file is a map lookup for lowercased mime types.
-Each mime type has the following properties:
-
-- `.source` - where the mime type is defined.
- If not set, it's probably a custom media type.
- - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
- - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
- - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
-- `.extensions[]` - known extensions associated with this mime type.
-- `.compressible` - whether a file of this type can be gzipped.
-- `.charset` - the default charset associated with this type, if any.
-
-If unknown, every property could be `undefined`.
-
-## Contributing
-
-To edit the database, only make PRs against `src/custom.json` or
-`src/custom-suffix.json`.
-
-The `src/custom.json` file is a JSON object with the MIME type as the keys
-and the values being an object with the following keys:
-
-- `compressible` - leave out if you don't know, otherwise `true`/`false` to
- indicate whether the data represented by the type is typically compressible.
-- `extensions` - include an array of file extensions that are associated with
- the type.
-- `notes` - human-readable notes about the type, typically what the type is.
-- `sources` - include an array of URLs of where the MIME type and the associated
- extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
- links to type aggregating sites and Wikipedia are _not acceptable_.
-

-### Adding Custom Media Types
-
-The best way to get new media types included in this library is to register
-them with the IANA. The community registration procedure is outlined in
-[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
-registered with the IANA are automatically pulled into this library.
-
-If that is not possible / feasible, they can be added directly here as a
-"custom" type. To do this, it is required to have a primary source that
-definitively lists the media type. If an extension is going to be listed as
-associateed with this media type, the source must definitively link the
-media type and extension as well.

-[![NPM Version][npm-version-image]][npm-url]
-[![NPM Downloads][npm-downloads-image]][npm-url]
-[![Node.js Version][node-version-image]][node-version-url]
-[![Build Status][travis-image]][travis-url]
-[![Test Coverage][coveralls-image]][coveralls-url]
-
-The ultimate javascript content-type utility.
-
-Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
-
-- __No fallbacks.__ Instead of naively returning the first available type,
- `mime-types` simply returns `false`, so do
- `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
-- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
-- No `.define()` functionality
-- Bug fixes for `.lookup(path)`
-
-Otherwise, the API is compatible with `mime` 1.x.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install mime-types
-```
-
-## Adding Types
-
-All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
-so open a PR there if you'd like to add mime types.
-
-## API
-
-<!-- eslint-disable no-unused-vars -->
-
-```js
-var mime = require('mime-types')
-```
-
-All functions return `false` if input is invalid or not found.
-
-### mime.lookup(path)
-
-Lookup the content-type associated with a file.
-
-<!-- eslint-disable no-undef -->
-
-```js
-mime.lookup('json') // 'application/json'
-mime.lookup('.md') // 'text/markdown'
-mime.lookup('file.html') // 'text/html'
-mime.lookup('folder/file.js') // 'application/javascript'
-mime.lookup('folder/.htaccess') // false
-
-mime.lookup('cats') // false
-```
-
-### mime.contentType(type)
-
-Create a full content-type header given a content-type or extension.
-When given an extension, `mime.lookup` is used to get the matching
-content-type, otherwise the given content-type is used. Then if the
-content-type does not already have a `charset` parameter, `mime.charset`
-is used to get the default charset and add to the returned content-type.
-
-<!-- eslint-disable no-undef -->
-
-```js
-mime.contentType('markdown') // 'text/x-markdown; charset=utf-8'
-mime.contentType('file.json') // 'application/json; charset=utf-8'
-mime.contentType('text/html') // 'text/html; charset=utf-8'
-mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
-
-// from a full path
-mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
-```
-
-### mime.extension(type)
-
-Get the default extension for a content-type.
-
-<!-- eslint-disable no-undef -->
-
-```js
-mime.extension('application/octet-stream') // 'bin'
-```
-
-### mime.charset(type)
-
-Lookup the implied default charset of a content-type.
-
-<!-- eslint-disable no-undef -->
-
-```js
-mime.charset('text/markdown') // 'UTF-8'
-```
-
-### var type = mime.types[extension]
-
-A map of content-types by extension.
-
-### [extensions...] = mime.extensions[type]
-
-A map of extensions by content-type.

+# [2.4.0](https://github.com/Automattic/socket.io-client/compare/2.3.1...2.4.0) (2021-01-04)
+
+The minor bump is matching the bump of the server, but there is no new feature in this release.
+
+
+## [2.3.1](https://github.com/socketio/socket.io-client/compare/2.3.0...2.3.1) (2020-09-30)
+
+The `debug` dependency has been reverted to `~3.1.0`, as the newer versions contains ES6 syntax which breaks in IE
+browsers.
+
+Please note that this only applied to users that bundle the Socket.IO client in their application, with webpack for
+example, as the "official" bundles (in the dist/ folder) were already transpiled with babel.
+
+For webpack users, you can also take a look at the [webpack-remove-debug](https://github.com/johngodley/webpack-remove-debug)
+plugin.
+
+### Bug Fixes
+
+* fix reconnection after opening socket asynchronously ([#1253](https://github.com/socketio/socket.io-client/issues/1253)) ([050108b](https://github.com/Automattic/socket.io-client/commit/050108b2281effda086b197cf174ee2e8e1aad79))

```html
<script src="/socket.io/socket.io.js"></script>
<script>
- var socket = io('http://localhost');
+ var socket = io();
socket.on('connect', function(){});
socket.on('event', function(data){});
socket.on('disconnect', function(){});
// with ES6 import
import io from 'socket.io-client';
-const socket = io('http://localhost');
+const socket = io();
```
A slim build (without `JSON3`, a JSON polyfill for IE6/IE7, and `debug`) is also available: `socket.io.slim.js`.
Add `socket.io-client` to your `package.json` and then:
```js
- var socket = require('socket.io-client')('http://localhost');
+ var socket = require('socket.io-client')('http://localhost:3000');
socket.on('connect', function(){});
socket.on('event', function(data){});
socket.on('disconnect', function(){});
```
+## Debug / logging
+
+In order to see all the client debug output, run the following command on the browser console – including the desired scope – and reload your app page:
+
+```
+localStorage.debug = '*';
+```
+
+And then, filter by the scopes you're interested in. See also: https://socket.io/docs/logging-and-debugging/
+

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows note
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Note that PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Then, run the program to be debugged as usual.
+
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

-# ws: a Node.js WebSocket library
-
-[](https://www.npmjs.com/package/ws)
-[](https://travis-ci.org/websockets/ws)
-[](https://ci.appveyor.com/project/lpinca/ws)
-[](https://coveralls.io/r/websockets/ws?branch=master)
-
-ws is a simple to use, blazing fast, and thoroughly tested WebSocket client
-and server implementation.
-
-Passes the quite extensive Autobahn test suite: [server][server-report],
-[client][client-report].
-
-**Note**: This module does not work in the browser. The client in the docs is a
-reference to a back end with the role of a client in the WebSocket
-communication. Browser clients must use the native
-[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) object.
-To make the same code work seamlessly on Node.js and the browser, you can use
-one of the many wrappers available on npm, like
-[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

-
-## Protocol support
-
-* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
-* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`)
-
-## Installing
-
-```
-npm install --save ws
-```
-
-### Opt-in for performance and spec compliance
-
-There are 2 optional modules that can be installed along side with the ws
-module. These modules are binary addons which improve certain operations.
-Prebuilt binaries are available for the most popular platforms so you don't
-necessarily need to have a C++ compiler installed on your machine.
-
-- `npm install --save-optional bufferutil`: Allows to efficiently perform
- operations such as masking and unmasking the data payload of the WebSocket
- frames.
-- `npm install --save-optional utf-8-validate`: Allows to efficiently check
- if a message contains valid UTF-8 as required by the spec.
-
-## API docs
-

-
-## WebSocket compression
-
-ws supports the [permessage-deflate extension][permessage-deflate] which
-enables the client and server to negotiate a compression algorithm and its
-parameters, and then selectively apply it to the data payloads of each
-WebSocket message.
-
-The extension is disabled by default on the server and enabled by default on
-the client. It adds a significant overhead in terms of performance and memory
-consumption so we suggest to enable it only if it is really needed.
-
-Note that Node.js has a variety of issues with high-performance compression,
-where increased concurrency, especially on Linux, can lead to
-[catastrophic memory fragmentation][node-zlib-bug] and slow performance.
-If you intend to use permessage-deflate in production, it is worthwhile to set
-up a test representative of your workload and ensure Node.js/zlib will handle
-it with acceptable performance and memory usage.
-
-Tuning of permessage-deflate can be done via the options defined below. You can
-also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
-into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
-
-See [the docs][ws-server-options] for more options.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({
- port: 8080,
- perMessageDeflate: {
- zlibDeflateOptions: { // See zlib defaults.
- chunkSize: 1024,
- memLevel: 7,
- level: 3,
- },
- zlibInflateOptions: {
- chunkSize: 10 * 1024
- },
- // Other options settable:
- clientNoContextTakeover: true, // Defaults to negotiated value.
- serverNoContextTakeover: true, // Defaults to negotiated value.
- clientMaxWindowBits: 10, // Defaults to negotiated value.
- serverMaxWindowBits: 10, // Defaults to negotiated value.
- // Below options specified as default values.
- concurrencyLimit: 10, // Limits zlib concurrency for perf.
- threshold: 1024, // Size (in bytes) below which messages
- // should not be compressed.
- }
-});
-```
-
-The client will only use the extension if it is supported and enabled on the
-server. To always disable the extension on the client set the
-`perMessageDeflate` option to `false`.
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path', {
- perMessageDeflate: false
-});
-```
-
-## Usage examples
-
-### Sending and receiving text data
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path');
-
-ws.on('open', function open() {
- ws.send('something');
-});
-
-ws.on('message', function incoming(data) {
- console.log(data);
-});
-```
-
-### Sending binary data
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path');
-
-ws.on('open', function open() {
- const array = new Float32Array(5);
-
- for (var i = 0; i < array.length; ++i) {
- array[i] = i / 2;
- }
-
- ws.send(array);
-});
-```
-
-### Simple server
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws) {
- ws.on('message', function incoming(message) {
- console.log('received: %s', message);
- });
-
- ws.send('something');
-});
-```
-
-### External HTTP/S server
-
-```js
-const fs = require('fs');
-const https = require('https');
-const WebSocket = require('ws');
-
-const server = new https.createServer({
- cert: fs.readFileSync('/path/to/cert.pem'),
- key: fs.readFileSync('/path/to/key.pem')
-});
-const wss = new WebSocket.Server({ server });
-
-wss.on('connection', function connection(ws) {
- ws.on('message', function incoming(message) {
- console.log('received: %s', message);
- });
-
- ws.send('something');
-});
-
-server.listen(8080);
-```
-
-### Multiple servers sharing a single HTTP/S server
-
-```js
-const http = require('http');
-const WebSocket = require('ws');
-
-const server = http.createServer();
-const wss1 = new WebSocket.Server({ noServer: true });
-const wss2 = new WebSocket.Server({ noServer: true });
-
-wss1.on('connection', function connection(ws) {
- // ...
-});
-
-wss2.on('connection', function connection(ws) {
- // ...
-});
-
-server.on('upgrade', function upgrade(request, socket, head) {
- const pathname = url.parse(request.url).pathname;
-
- if (pathname === '/foo') {
- wss1.handleUpgrade(request, socket, head, function done(ws) {
- wss1.emit('connection', ws, request);
- });
- } else if (pathname === '/bar') {
- wss2.handleUpgrade(request, socket, head, function done(ws) {
- wss2.emit('connection', ws, request);
- });
- } else {
- socket.destroy();
- }
-});
-
-server.listen(8080);
-```
-
-### Server broadcast
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-// Broadcast to all.
-wss.broadcast = function broadcast(data) {
- wss.clients.forEach(function each(client) {
- if (client.readyState === WebSocket.OPEN) {
- client.send(data);
- }
- });
-};
-
-wss.on('connection', function connection(ws) {
- ws.on('message', function incoming(data) {
- // Broadcast to everyone else.
- wss.clients.forEach(function each(client) {
- if (client !== ws && client.readyState === WebSocket.OPEN) {
- client.send(data);
- }
- });
- });
-});
-```
-
-### echo.websocket.org demo
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('wss://echo.websocket.org/', {
- origin: 'https://websocket.org'
-});
-
-ws.on('open', function open() {
- console.log('connected');
- ws.send(Date.now());
-});
-
-ws.on('close', function close() {
- console.log('disconnected');
-});
-
-ws.on('message', function incoming(data) {
- console.log(`Roundtrip time: ${Date.now() - data} ms`);
-
- setTimeout(function timeout() {
- ws.send(Date.now());
- }, 500);
-});
-```
-
-### Other examples
-
-For a full example with a browser client communicating with a ws server, see the
-examples folder.
-
-Otherwise, see the test cases.
-
-## Error handling best practices
-
-```js
-// If the WebSocket is closed before the following send is attempted
-ws.send('something');
-
-// Errors (both immediate and async write errors) can be detected in an optional
-// callback. The callback is also the only way of being notified that data has
-// actually been sent.
-ws.send('something', function ack(error) {
- // If error is not defined, the send has been completed, otherwise the error
- // object will indicate what failed.
-});
-
-// Immediate errors can also be handled with `try...catch`, but **note** that
-// since sends are inherently asynchronous, socket write failures will *not* be
-// captured when this technique is used.
-try { ws.send('something'); }
-catch (e) { /* handle error */ }
-```
-
-## FAQ
-
-### How to get the IP address of the client?
-
-The remote IP address can be obtained from the raw socket.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws, req) {
- const ip = req.connection.remoteAddress;
-});
-```
-
-When the server runs behind a proxy like NGINX, the de-facto standard is to use
-the `X-Forwarded-For` header.
-
-```js
-wss.on('connection', function connection(ws, req) {
- const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
-});
-```
-
-### How to detect and close broken connections?
-
-Sometimes the link between the server and the client can be interrupted in a
-way that keeps both the server and the client unaware of the broken state of the
-connection (e.g. when pulling the cord).
-
-In these cases ping messages can be used as a means to verify that the remote
-endpoint is still responsive.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-function noop() {}
-
-function heartbeat() {
- this.isAlive = true;
-}
-
-wss.on('connection', function connection(ws) {
- ws.isAlive = true;
- ws.on('pong', heartbeat);
-});
-
-const interval = setInterval(function ping() {
- wss.clients.forEach(function each(ws) {
- if (ws.isAlive === false) return ws.terminate();
-
- ws.isAlive = false;
- ws.ping(noop);
- });
-}, 30000);
-```
-
-Pong messages are automatically sent in response to ping messages as required
-by the spec.
-
-### How to connect via a proxy?
-
-Use a custom `http.Agent` implementation like [https-proxy-agent][] or
-[socks-proxy-agent][].

-# Async-Limiter
-
-A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
-
-[](http://www.npmjs.org/async-limiter)
-[](https://travis-ci.org/STRML/async-limiter)
-[](https://coveralls.io/r/STRML/async-limiter)
-
-This module exports a class `Limiter` that implements some of the `Array` API.
-Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
-
-## Motivation
-
-Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
-run at infinite concurrency.
-
-In this case, it is actually faster, and takes far less memory, to limit concurrency.
-
-This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
-make this module faster or lighter, but new functionality is not desired.
-
-Style should confirm to nodejs/node style.
-
-## Example
-
-``` javascript
-var Limiter = require('async-limiter')
-
-var t = new Limiter({concurrency: 2});
-var results = []
-
-// add jobs using the familiar Array API
-t.push(function (cb) {
- results.push('two')
- cb()
-})
-
-t.push(
- function (cb) {
- results.push('four')
- cb()
- },
- function (cb) {
- results.push('five')
- cb()
- }
-)
-
-t.unshift(function (cb) {
- results.push('one')
- cb()
-})
-
-t.splice(2, 0, function (cb) {
- results.push('three')
- cb()
-})
-
-// Jobs run automatically. If you want a callback when all are done,
-// call 'onDone()'.
-t.onDone(function () {
- console.log('all done:', results)
-})
-```
-
-## Zlib Example
-
-```js
-const zlib = require('zlib');
-const Limiter = require('async-limiter');
-
-const message = {some: "data"};
-const payload = new Buffer(JSON.stringify(message));
-
-// Try with different concurrency values to see how this actually
-// slows significantly with higher concurrency!
-//
-// 5: 1398.607ms
-// 10: 1375.668ms
-// Infinity: 4423.300ms
-//
-const t = new Limiter({concurrency: 5});
-function deflate(payload, cb) {
- t.push(function(done) {
- zlib.deflate(payload, function(err, buffer) {
- done();
- cb(err, buffer);
- });
- });
-}
-
-console.time('deflate');
-for(let i = 0; i < 30000; ++i) {
- deflate(payload, function (err, buffer) {});
-}
-t.onDone(function() {
- console.timeEnd('deflate');
-});
-```
-
-## Install
-
-`npm install async-limiter`
-
-## Test
-
-`npm test`
-
-## API
-
-### `var t = new Limiter([opts])`
-Constructor. `opts` may contain inital values for:
-* `t.concurrency`
-
-## Instance methods
-
-### `t.onDone(fn)`
-`fn` will be called once and only once, when the queue is empty.
-
-## Instance methods mixed in from `Array`
-Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
-### `t.push(element1, ..., elementN)`
-### `t.unshift(element1, ..., elementN)`
-### `t.splice(index , howMany[, element1[, ...[, elementN]]])`
-
-## Properties
-### `t.concurrency`
-Max number of jobs the queue should process concurrently, defaults to `Infinity`.
-
-### `t.length`
-Jobs pending + jobs to process (readonly).
