11 <h2 id="DESCRIPTION">DESCRIPTION</h2>
13 <p>npm gets its configuration values from 6 sources, in this priority:</p>
15 <h3 id="Command-Line-Flags">Command Line Flags</h3>
17 <p>Putting <code>--foo bar</code> on the command line sets the <code>foo</code> configuration
18 parameter to <code>"bar"</code>. A <code>--</code> argument tells the cli parser to stop
19 reading flags. A <code>--flag</code> parameter that is at the <em>end</em> of the
20 command will be given the value of <code>true</code>.</p>
22 <h3 id="Environment-Variables">Environment Variables</h3>
24 <p>Any environment variables that start with <code>npm_config_</code> will be
25 interpreted as a configuration parameter. For example, putting
26 <code>npm_config_foo=bar</code> in your environment will set the <code>foo</code>
27 configuration parameter to <code>bar</code>. Any environment configurations that
28 are not given a value will be given the value of <code>true</code>. Config
29 values are case-insensitive, so <code>NPM_CONFIG_FOO=bar</code> will work the
32 <h3 id="npmrc-Files">npmrc Files</h3>
34 <p>The three relevant files are:</p>
36 <ul><li>per-user config file (~/.npmrc)</li><li>global config file ($PREFIX/npmrc)</li><li>npm builtin config file (/path/to/npm/npmrc)</li></ul>
38 <p>See <a href="../files/npmrc.html">npmrc(5)</a> for more details.</p>
40 <h3 id="Default-Configs">Default Configs</h3>
42 <p>A set of configuration parameters that are internal to npm, and are
43 defaults if nothing else is specified.</p>
45 <h2 id="Shorthands-and-Other-CLI-Niceties">Shorthands and Other CLI Niceties</h2>
47 <p>The following shorthands are parsed on the command-line:</p>
49 <ul><li><code>-v</code>: <code>--version</code></li><li><code>-h</code>, <code>-?</code>, <code>--help</code>, <code>-H</code>: <code>--usage</code></li><li><code>-s</code>, <code>--silent</code>: <code>--loglevel silent</code></li><li><code>-q</code>, <code>--quiet</code>: <code>--loglevel warn</code></li><li><code>-d</code>: <code>--loglevel info</code></li><li><code>-dd</code>, <code>--verbose</code>: <code>--loglevel verbose</code></li><li><code>-ddd</code>: <code>--loglevel silly</code></li><li><code>-g</code>: <code>--global</code></li><li><code>-l</code>: <code>--long</code></li><li><code>-m</code>: <code>--message</code></li><li><code>-p</code>, <code>--porcelain</code>: <code>--parseable</code></li><li><code>-reg</code>: <code>--registry</code></li><li><code>-v</code>: <code>--version</code></li><li><code>-f</code>: <code>--force</code></li><li><code>-desc</code>: <code>--description</code></li><li><code>-S</code>: <code>--save</code></li><li><code>-D</code>: <code>--save-dev</code></li><li><code>-O</code>: <code>--save-optional</code></li><li><code>-B</code>: <code>--save-bundle</code></li><li><code>-y</code>: <code>--yes</code></li><li><code>-n</code>: <code>--yes false</code></li><li><code>ll</code> and <code>la</code> commands: <code>ls --long</code></li></ul>
51 <p>If the specified configuration param resolves unambiguously to a known
52 configuration parameter, then it is expanded to that configuration
53 parameter. For example:</p>
55 <pre><code>npm ls --par
57 npm ls --parseable</code></pre>
59 <p>If multiple single-character shorthands are strung together, and the
60 resulting combination is unambiguously not some other configuration
61 param, then it is expanded to its various component pieces. For
64 <pre><code>npm ls -gpld
66 npm ls --global --parseable --long --loglevel info</code></pre>
68 <h2 id="Per-Package-Config-Settings">Per-Package Config Settings</h2>
70 <p>When running scripts (see <code><a href="../misc/npm-scripts.html">npm-scripts(7)</a></code>) the package.json "config"
71 keys are overwritten in the environment if there is a config param of
72 <code><name>[@<version>]:<key></code>. For example, if the package.json has
75 <pre><code>{ "name" : "foo"
76 , "config" : { "port" : "8080" }
77 , "scripts" : { "start" : "node server.js" } }</code></pre>
79 <p>and the server.js is this:</p>
81 <pre><code>http.createServer(...).listen(process.env.npm_package_config_port)</code></pre>
83 <p>then the user could change the behavior by doing:</p>
85 <pre><code>npm config set foo:port 80</code></pre>
87 <p>See <a href="../files/package.json.html">package.json(5)</a> for more information.</p>
