|
||
|
|
<p>npm is the package manager for the Node JavaScript platform. It puts
|
||
|
|
modules in place so that node can find them, and manages dependency
|
||
|
|
conflicts intelligently.</p>
|
||
|
|
<p>It is extremely configurable to support a variety of use cases. Most
|
||
|
|
commonly, you use it to publish, discover, install, and develop node
|
||
|
|
programs.</p>
|
||
|
|
<p>Run <code>npm help</code> to get a list of available commands.</p>
|
||
|
|
<h3 id="important">Important</h3>
|
||
|
|
<p>npm comes preconfigured to use npm's public registry at
|
||
|
|
<a href="https://registry.npmjs.org">https://registry.npmjs.org</a> by default. Use of the npm public registry is
|
||
|
|
subject to terms of use available at
|
||
|
|
<a href="https://docs.npmjs.com/policies/terms">https://docs.npmjs.com/policies/terms</a>.</p>
|
||
|
|
<p>You can configure npm to use any compatible registry you like, and even
|
||
|
|
run your own registry. Use of someone else's registry is governed by
|
||
|
|
their terms of use.</p>
|
||
|
|
<h3 id="introduction">Introduction</h3>
|
||
|
|
<p>You probably got npm because you want to install stuff.</p>
|
||
|
|
<p>The very first thing you will most likely want to run in any node
|
||
|
|
program is <code>npm install</code> to install its dependencies.</p>
|
||
|
|
<p>You can also run <code>npm install blerg</code> to install the latest version of
|
||
|
|
"blerg". Check out <a href="../commands/npm-install.html"><code>npm install</code></a> for more
|
||
|
|
info. It can do a lot of stuff.</p>
|
||
|
|
<p>Use the <code>npm search</code> command to show everything that's available in the
|
||
|
|
public registry. Use <code>npm ls</code> to show everything you've installed.</p>
|
||
|
|
<h3 id="dependencies">Dependencies</h3>
|
||
|
|
<p>If a package lists a dependency using a git URL, npm will install that
|
||
|
|
dependency using the <a href="https://github.com/git-guides/install-git"><code>git</code></a>
|
||
|
|
command and will generate an error if it is not installed.</p>
|
||
|
|
<p>If one of the packages npm tries to install is a native node module and
|
||
|
|
requires compiling of C++ Code, npm will use
|
||
|
|
<a href="https://github.com/nodejs/node-gyp">node-gyp</a> for that task.
|
||
|
|
For a Unix system, <a href="https://github.com/nodejs/node-gyp">node-gyp</a>
|
||
|
|
needs Python, make and a buildchain like GCC. On Windows,
|
||
|
|
Python and Microsoft Visual Studio C++ are needed. For more information
|
||
|
|
visit <a href="https://github.com/nodejs/node-gyp">the node-gyp repository</a> and
|
||
|
|
the <a href="https://github.com/nodejs/node-gyp/wiki">node-gyp Wiki</a>.</p>
|
||
|
|
<h3 id="directories">Directories</h3>
|
||
|
|
<p>See <a href="../configuring-npm/folders.html"><code>folders</code></a> to learn about where npm puts
|
||
|
|
stuff.</p>
|
||
|
|
<p>In particular, npm has two modes of operation:</p>
|
||
|
|
<ul>
|
||
|
|
<li>local mode:
|
||
|
|
npm installs packages into the current project directory, which
|
||
|
|
defaults to the current working directory. Packages install to
|
||
|
|
<code>./node_modules</code>, and bins to <code>./node_modules/.bin</code>.</li>
|
||
|
|
<li>global mode:
|
||
|
|
npm installs packages into the install prefix at
|
||
|
|
<code>$npm_config_prefix/lib/node_modules</code> and bins to
|
||
|
|
<code>$npm_config_prefix/bin</code>.</li>
|
||
|
|
</ul>
|
||
|
|
<p>Local mode is the default. Use <code>-g</code> or <code>--global</code> on any command to
|
||
|
|
run in global mode instead.</p>
|
||
|
|
<h3 id="developer-usage">Developer Usage</h3>
|
||
|
|
<p>If you're using npm to develop and publish your code, check out the
|
||
|
|
following help topics:</p>
|
||
|
|
<ul>
|
||
|
|
<li>json:
|
||
|
|
Make a package.json file. See
|
||
|
|
<a href="../configuring-npm/package-json.html"><code>package.json</code></a>.</li>
|
||
|
|
<li>link:
|
||
|
|
Links your current working code into Node's path, so that you don't
|
||
|
|
have to reinstall every time you make a change. Use <a href="../commands/npm-link.html"><code>npm link</code></a> to do this.</li>
|
||
|
|
<li>install:
|
||
|
|
It's a good idea to install things if you don't need the symbolic
|
||
|
|
link. Especially, installing other peoples code from the registry is
|
||
|
|
done via <a href="../commands/npm-install.html"><code>npm install</code></a></li>
|
||
|
|
<li>adduser:
|
||
|
|
Create an account or log in. When you do this, npm will store
|
||
|
|
credentials in the user config file config file.</li>
|
||
|
|
<li>publish:
|
||
|
|
Use the <a href="../commands/npm-publish.html"><code>npm publish</code></a> command to upload your
|
||
|
|
code to the registry.</li>
|
||
|
|
</ul>
|
||
|
|
<h4 id="configuration">Configuration</h4>
|
||
|
|
<p>npm is extremely configurable. It reads its configuration options from
|
||
|
|
5 places.</p>
|
||
|
|
<ul>
|
||
|
|
<li>Command line switches:
|
||
|
|
Set a config with <code>--key val</code>. All keys take a value, even if they
|
||
|
|
are booleans (the config parser doesn't know what the options are at
|
||
|
|
the time of parsing). If you do not provide a value (<code>--key</code>) then
|
||
|
|
the option is set to boolean <code>true</code>.</li>
|
||
|
|
<li>Environment Variables:
|
||
|
|
Set any config by prefixing the name in an environment variable with
|
||
|
|
<code>npm_config_</code>. For example, <code>export npm_config_key=val</code>.</li>
|
||
|
|
<li>User Configs:
|
||
|
|
The file at <code>$HOME/.npmrc</code> is an ini-formatted list of configs. If
|
||
|
|
present, it is parsed. If the <code>userconfig</code> option is set in the cli
|
||
|
|
or env, that file will be used instead.</li>
|
||
|
|
<li>Global Configs:
|
||
|
|
The file found at <code>./etc/npmrc</code> (relative to the global prefix will be
|
||
|
|
parsed if it is found. See <a href="../commands/npm-prefix.html"><code>npm prefix</code></a> for
|
||
|
|
more info on the global prefix. If the <code>globalconfig</code> option is set
|
||
|
|
in the cli, env, or user config, then that file is parsed instead.</li>
|
||
|
|
<li>Defaults:
|
||
|
|
npm's default configuration options are defined in
|
||
|
|
lib/utils/config-defs.js. These must not be changed.</li>
|
||
|
|
</ul>
|
||
|
|
<p>See <a href="../using-npm/config.html"><code>config</code></a> for much much more information.</p>
