To save rom size, the duplicated libraries are removed.

-# 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).

-## 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 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');

-### 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);
-```

-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][].

-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);

-# 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).

-## 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 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

-
-## 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][].

-# 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`

-
-A tiny node.js debugging utility modelled after node core's debugging technique.
-
-**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
-
-## 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_:
-
-```js
-var debug = require('debug')('http')
- , http = require('http')
- , name = 'My App';
-
-// fake app
-
-debug('booting %s', 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_:
-
-```js
-var debug = require('debug')('worker');
-
-setInterval(function(){
- debug('doing some work');
-}, 1000);
-```
-
- The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
-
- 
-
- 
-
-#### 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.
-
-## 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.
-
- 
-
- When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
-
- 
-
-## 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".
-
-## 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_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);
-```
-
-#### Web Inspector Colors
-
- 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).
-
- Colored output looks something like:
-
- 
-
-
-## Output streams
-
- By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
-
-Example _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');
-```

-# 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`

-# 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
-ms('-3 days') // -259200000
-ms('-1h') // -3600000
-ms('-200') // -200
-```
-
-### Convert from Milliseconds
-
-```js
-ms(60000) // "1m"
-ms(2 * 60000) // "2m"
-ms(-3 * 60000) // "-3m"
-ms(ms('10 hours')) // "10h"
-```
-
-### Time Format Written-Out
-
-```js
-ms(60000, { long: true }) // "1 minute"
-ms(2 * 60000, { long: true }) // "2 minutes"
-ms(-3 * 60000, { long: true }) // "-3 minutes"
-ms(ms('10 hours'), { long: true }) // "10 hours"
-```
-
-## Features
-
-- Works both in [Node.js](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 milliseconds is returned
-
-## Related Packages
-
-- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
-
-## 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.js will now use your clone of ms!
-
-As always, you can run the tests using: `npm test`

-# Emitter [](https://travis-ci.org/component/emitter)\r
-\r
- Event emitter component.\r
-\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

-# 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`

-# socket.io-parser
-
-[](http://travis-ci.org/socketio/socket.io-parser)
-[](http://badge.fury.io/js/socket.io-parser)
-
-A socket.io encoder and decoder written in JavaScript complying with version `3`
-of [socket.io-protocol](https://github.com/socketio/socket.io-protocol).
-Used by [socket.io](https://github.com/automattic/socket.io) and
-[socket.io-client](https://github.com/automattic/socket.io-client).
-
-## Parser API
-
- socket.io-parser is the reference implementation of socket.io-protocol. Read
- the full API here:
- [socket.io-protocol](https://github.com/learnboost/socket.io-protocol).
-
-## Example Usage
-
-### Encoding and decoding a packet
-
-```js
-var parser = require('socket.io-parser');
-var encoder = new parser.Encoder();
-var packet = {
- type: parser.EVENT,
- data: 'test-packet',
- id: 13
-};
-encoder.encode(packet, function(encodedPackets) {
- var decoder = new parser.Decoder();
- decoder.on('decoded', function(decodedPacket) {
- // decodedPacket.type == parser.EVENT
- // decodedPacket.data == 'test-packet'
- // decodedPacket.id == 13
- });
-
- for (var i = 0; i < encodedPackets.length; i++) {
- decoder.add(encodedPackets[i]);
- }
-});
-```
-
-### Encoding and decoding a packet with binary data
-
-```js
-var parser = require('socket.io-parser');
-var encoder = new parser.Encoder();
-var packet = {
- type: parser.BINARY_EVENT,
- data: {i: new Buffer(1234), j: new Blob([new ArrayBuffer(2)])}
- id: 15
-};
-encoder.encode(packet, function(encodedPackets) {
- var decoder = new parser.Decoder();
- decoder.on('decoded', function(decodedPacket) {
- // decodedPacket.type == parser.BINARY_EVENT
- // Buffer.isBuffer(decodedPacket.data.i) == true
- // Buffer.isBuffer(decodedPacket.data.j) == true
- // decodedPacket.id == 15
- });
-
- for (var i = 0; i < encodedPackets.length; i++) {
- decoder.add(encodedPackets[i]);
- }
-});
-```
-See the test suite for more examples of how socket.io-parser is used.
