|
|
|
|
<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 wide variety of use cases.
|
|
Most commonly, it is used to publish, discover, install, and develop node
|
|
programs.</p>
|
|
|
|
<p>Run <code>npm help</code> to get a list of available commands.</p>
|
|
|
|
<h2 id="INTRODUCTION">INTRODUCTION</h2>
|
|
|
|
<p>You probably got npm because you want to install stuff.</p>
|
|
|
|
<p>Use <code>npm install blerg</code> to install the latest version of "blerg". Check out
|
|
<code><a href="../doc/install.html">install(1)</a></code> 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.
|
|
Use <code>npm ls</code> to show everything you've installed.</p>
|
|
|
|
<h2 id="DIRECTORIES">DIRECTORIES</h2>
|
|
|
|
<p>See <code><a href="../doc/folders.html">folders(1)</a></code> to learn about where npm puts stuff.</p>
|
|
|
|
<p>In particular, npm has two modes of operation:</p>
|
|
|
|
<ul><li>global mode:<br />npm installs packages into the install prefix at
|
|
<code>prefix/lib/node_modules</code> and bins are installed in <code>prefix/bin</code>.</li><li>local mode:<br />npm installs packages into the current project directory, which
|
|
defaults to the current working directory. Packages are installed to
|
|
<code>./node_modules</code>, and bins are installed to <code>./node_modules/.bin</code>.</li></ul>
|
|
|
|
<p>Local mode is the default. Use <code>--global</code> or <code>-g</code> on any command to
|
|
operate in global mode instead.</p>
|
|
|
|
<h2 id="DEVELOPER-USAGE">DEVELOPER USAGE</h2>
|
|
|
|
<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 <code><a href="../doc/json.html">json(1)</a></code>.</li><li>link:
|
|
For linking your current working code into Node's path, so that you
|
|
don't have to reinstall every time you make a change. Use
|
|
<code>npm link</code> 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
|
|
<code>npm install</code></li><li>adduser:
|
|
Create an account or log in. Credentials are stored in the
|
|
user config file.</li><li>publish:
|
|
Use the <code>npm publish</code> command to upload your code to the registry.</li></ul>
|
|
|
|
<h2 id="CONFIGURATION">CONFIGURATION</h2>
|
|
|
|
<p>npm is extremely configurable. It reads its configuration options from
|
|
5 places.</p>
|
|
|
|
<ul><li>Command line switches:<br />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 no value is provided, then the option is set
|
|
to boolean <code>true</code>.</li><li>Environment Variables:<br />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:<br />The file at $HOME/.npmrc 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, then that will be used instead.</li><li>Global Configs:<br />The file found at ../etc/npmrc (from the node executable, by default
|
|
this resolves to /usr/local/etc/npmrc) will be parsed if it is found.
|
|
If the <code>globalconfig</code> option is set in the cli, env, or user config,
|
|
then that file is parsed instead.</li><li>Defaults:<br />npm's default configuration options are defined in
|
|
lib/utils/config-defs.js. These must not be changed.</li></ul>
|
|
|
|
<p>See <code><a href="../doc/config.html">config(1)</a></code> for much much more information.</p>

<h2 id="CONTRIBUTIONS">CONTRIBUTIONS</h2>
|
|
|
|
<p>Patches welcome!</p>
|
|
|
|
<ul><li>code:
|
|
Read through <code><a href="../doc/coding-style.html">coding-style(1)</a></code> if you plan to submit code.
|
|
You don't have to agree with it, but you do have to follow it.</li><li>docs:
|
|
If you find an error in the documentation, edit the appropriate markdown
|
|
file in the "doc" folder. (Don't worry about generating the man page.)</li></ul>
|
|
|
|
<p>Contributors are listed in npm's <code>package.json</code> file. You can view them
|
|
easily by doing <code>npm view npm contributors</code>.</p>
