<h1><a href="../misc/npm-config.html">npm-config</a></h1> <p>More than you probably want to know about npm configuration</p>
<h2 id="description">DESCRIPTION</h2>
<p>npm gets its configuration values from 6 sources, in this priority:</p>
<h3 id="command-line-flags">Command Line Flags</h3>
<p>Putting <code>--foo bar</code> on the command line sets the <code>foo</code> configuration
parameter to <code>"bar"</code>. A <code>--</code> argument tells the cli parser to stop
reading flags. A <code>--flag</code> parameter that is at the <em>end</em> of the
command will be given the value of <code>true</code>.</p>
<h3 id="environment-variables">Environment Variables</h3>
<p>Any environment variables that start with <code>npm_config_</code> will be
interpreted as a configuration parameter. For example, putting
<code>npm_config_foo=bar</code> in your environment will set the <code>foo</code>
configuration parameter to <code>bar</code>. Any environment configurations that
are not given a value will be given the value of <code>true</code>. Config
values are case-insensitive, so <code>NPM_CONFIG_FOO=bar</code> will work the
same.</p>
<h3 id="npmrc-files">npmrc Files</h3>
<p>The four relevant files are:</p>
<ul>
<li>per-project config file (/path/to/my/project/.npmrc)</li>
<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>
<p>See <a href="../files/npmrc.html">npmrc(5)</a> for more details.</p>
<h3 id="default-configs">Default Configs</h3>
<p>A set of configuration parameters that are internal to npm, and are
defaults if nothing else is specified.</p>
<h2 id="shorthands-and-other-cli-niceties">Shorthands and Other CLI Niceties</h2>
<p>The following shorthands are parsed on the command-line:</p>
<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>-E</code>: <code>--save-exact</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>
<p>If the specified configuration param resolves unambiguously to a known
configuration parameter, then it is expanded to that configuration
parameter. For example:</p>
<pre><code>npm ls --par
# same as:
npm ls --parseable
</code></pre><p>If multiple single-character shorthands are strung together, and the
resulting combination is unambiguously not some other configuration
param, then it is expanded to its various component pieces. For
example:</p>
<pre><code>npm ls -gpld
# same as:
npm ls --global --parseable --long --loglevel info
</code></pre><h2 id="per-package-config-settings">Per-Package Config Settings</h2>
<p>When running scripts (see <code><a href="../misc/npm-scripts.html">npm-scripts(7)</a></code>) the package.json "config"
keys are overwritten in the environment if there is a config param of
<code><name>[@<version>]:<key></code>. For example, if the package.json has
this:</p>
<pre><code>{ "name" : "foo"
, "config" : { "port" : "8080" }
, "scripts" : { "start" : "node server.js" } }
</code></pre><p>and the server.js is this:</p>
<pre><code>http.createServer(...).listen(process.env.npm_package_config_port)
</code></pre><p>then the user could change the behavior by doing:</p>
<pre><code>npm config set foo:port 80
</code></pre><p>See <a href="../files/package.json.html">package.json(5)</a> for more information.</p>

</ul>
<p>Tells npm to create symlinks (or <code>.cmd</code> shims on Windows) for package
executables.</p>

the fact that some file systems don't support symlinks, even on
ostensibly Unix systems.</p>

<li>Default: OS X: <code>"open"</code>, Windows: <code>"start"</code>, Others: <code>"xdg-open"</code></li>

<li>Type: String or null</li>

to trust only that specific signing authority.</p>

<ul>
<li>Default: <code>null</code></li>
<li>Type: path</li>

<p>A path to a file containing one or multiple Certificate Authority signing
certificates. Similar to the <code>ca</code> setting, but allows for multiple CA's, as
well as for the CA information to be stored in a file on disk.</p>
<h3 id="cache">cache</h3>
<ul>
<li>Default: Windows: <code>%AppData%\npm-cache</code>, Posix: <code>~/.npm</code></li>

<li>Type: Number</li>
</ul>
<p>The minimum time (in seconds) to keep items in the registry cache before
