<pre><code class="language-bash">npm run-script <command> [-- <args>]
|
|
|
|
aliases: run, rum, urn
|
|
</code></pre>
|
|
<h3 id="description">Description</h3>
|
|
<p>This runs an arbitrary command from a package's <code>"scripts"</code> object. If no
|
|
<code>"command"</code> is provided, it will list the available scripts.</p>
|
|
<p><code>run[-script]</code> is used by the test, start, restart, and stop commands, but
|
|
can be called directly, as well. When the scripts in the package are
|
|
printed out, they're separated into lifecycle (test, start, restart) and
|
|
directly-run scripts.</p>
|
|
<p>Any positional arguments are passed to the specified script. Use <code>--</code> to
|
|
pass <code>-</code>-prefixed flags and options which would otherwise be parsed by npm.</p>
|
|
<p>For example:</p>
|
|
<pre><code class="language-bash">npm run test -- --grep="pattern"
|
|
</code></pre>
|
|
<p>The arguments will only be passed to the script specified after <code>npm run</code>
|
|
and not to any <code>pre</code> or <code>post</code> script.</p>
|
|
<p>The <code>env</code> script is a special built-in command that can be used to list
|
|
environment variables that will be available to the script at runtime. If an
|
|
"env" command is defined in your package, it will take precedence over the
|
|
built-in.</p>
|
|
<p>In addition to the shell's pre-existing <code>PATH</code>, <code>npm run</code> adds
|
|
<code>node_modules/.bin</code> to the <code>PATH</code> provided to scripts. Any binaries
|
|
provided by locally-installed dependencies can be used without the
|
|
<code>node_modules/.bin</code> prefix. For example, if there is a <code>devDependency</code> on
|
|
<code>tap</code> in your package, you should write:</p>
|
|
<pre><code class="language-bash">"scripts": {"test": "tap test/*.js"}
|
|
</code></pre>
|
|
<p>instead of</p>
|
|
<pre><code class="language-bash">"scripts": {"test": "node_modules/.bin/tap test/*.js"}
|
|
</code></pre>
|
|
<p>The actual shell your script is run within is platform dependent. By default,
|
|
on Unix-like systems it is the <code>/bin/sh</code> command, on Windows it is
|
|
<code>cmd.exe</code>.
|
|
The actual shell referred to by <code>/bin/sh</code> also depends on the system.
|
|
You can customize the shell with the
|
|
<a href="../using-npm/config#script-shell.html"><code>script-shell</code> config</a>.</p>
|
|
<p>Scripts are run from the root of the package folder, regardless of what the
|
|
current working directory is when <code>npm run</code> is called. If you want your
|
|
script to use different behavior based on what subdirectory you're in, you
|
|
can use the <code>INIT_CWD</code> environment variable, which holds the full path you
|
|
were in when you ran <code>npm run</code>.</p>
|
|
<p><code>npm run</code> sets the <code>NODE</code> environment variable to the <code>node</code> executable
|
|
with which <code>npm</code> is executed.</p>
|
|
<p>If you try to run a script without having a <code>node_modules</code> directory and it
|
|
fails, you will be given a warning to run <code>npm install</code>, just in case you've
|
|
forgotten.</p>
|
|
<h3 id="workspaces-support">Workspaces support</h3>
|
|
<p>You may use the <a href="../using-npm/config#workspace.html"><code>workspace</code></a> or
|
|
<a href="../using-npm/config#workspaces.html"><code>workspaces</code></a> configs in order to run an
|
|
arbitrary command from a package's <code>"scripts"</code> object in the context of the
|
|
specified workspaces. If no <code>"command"</code> is provided, it will list the available
|
|
scripts for each of these configured workspaces.</p>
|
|
<p>Given a project with configured workspaces, e.g:</p>
|
|
<pre><code>.
|
|
+-- package.json
|
|
`-- packages
|
|
+-- a
|
|
| `-- package.json
|
|
+-- b
|
|
| `-- package.json
|
|
`-- c
|
|
`-- package.json
|
|
</code></pre>
|
|
<p>Assuming the workspace configuration is properly set up at the root level
|
|
<code>package.json</code> file. e.g:</p>
|
|
<pre><code>{
|
|
"workspaces": [ "./packages/*" ]
|
|
}
|
|
</code></pre>
|
|
<p>And that each of the configured workspaces has a configured <code>test</code> script,
|
|
we can run tests in all of them using the
|
|
<a href="../using-npm/config#workspaces.html"><code>workspaces</code> config</a>:</p>
|
|
<pre><code>npm test --workspaces
|
|
</code></pre>
|
|
<h4 id="filtering-workspaces">Filtering workspaces</h4>
|
|
<p>It's also possible to run a script in a single workspace using the <code>workspace</code>
|
|
config along with a name or directory path:</p>
|
|
<pre><code>npm test --workspace=a
|
|
</code></pre>
|
|
<p>The <code>workspace</code> config can also be specified multiple times in order to run a
|
|
specific script in the context of multiple workspaces. When defining values for
|
|
the <code>workspace</code> config in the command line, it also possible to use <code>-w</code> as a
|
|
shorthand, e.g:</p>
|
|
<pre><code>npm test -w a -w b
|
|
</code></pre>
|
|
<p>This last command will run <code>test</code> in both <code>./packages/a</code> and <code>./packages/b</code>
|
|
packages.</p>
|
|
<h3 id="configuration">Configuration</h3>
|
|
<h4 id="workspace"><code>workspace</code></h4>
|
|
<ul>
|
|
<li>Default:</li>
|
|
<li>Type: String (can be set multiple times)</li>
|
|
</ul>
|
|
<p>Enable running a command in the context of the configured workspaces of the
|
|
current project while filtering by running only the workspaces defined by
|
|
this configuration option.</p>
|
|
<p>Valid values for the <code>workspace</code> config are either:</p>
|
|
<ul>
|
|
<li>Workspace names</li>
|
|
<li>Path to a workspace directory</li>
|
|
<li>Path to a parent workspace directory (will result in selecting all
|
|
workspaces within that folder)</li>
|
|
</ul>
|
|
<p>When set for the <code>npm init</code> command, this may be set to the folder of a
|
|
workspace which does not yet exist, to create the folder and set it up as a
|
|
brand new workspace within the project.</p>
|
|
<p>This value is not exported to the environment for child processes.</p>
|
|
<h4 id="workspaces"><code>workspaces</code></h4>
|
|
<ul>
|
|
<li>Default: null</li>
|
|
<li>Type: null or Boolean</li>
|
|
</ul>
|
|
<p>Set to true to run the command in the context of <strong>all</strong> configured
|
|
workspaces.</p>
|
|
<p>Explicitly setting this to false will cause commands like <code>install</code> to
|
|
ignore workspaces altogether. When not set explicitly:</p>
|
|
<ul>
|
|
<li>Commands that operate on the <code>node_modules</code> tree (install, update, etc.)
|
|
will link workspaces into the <code>node_modules</code> folder. - Commands that do
|
|
other things (test, exec, publish, etc.) will operate on the root project,
|
|
<em>unless</em> one or more workspaces are specified in the <code>workspace</code> config.</li>
|
|
</ul>
|
|
<p>This value is not exported to the environment for child processes.</p>
|
|
<h4 id="include-workspace-root"><code>include-workspace-root</code></h4>
|
|
<ul>
|
|
<li>Default: false</li>
|
|
<li>Type: Boolean</li>
|
|
</ul>
|
|
<p>Include the workspace root when workspaces are enabled for a command.</p>
|
|
<p>When false, specifying individual workspaces via the <code>workspace</code> config, or
|
|
all workspaces via the <code>workspaces</code> flag, will cause npm to operate only on
|
|
the specified workspaces, and not on the root project.</p>
|
|
<p>This value is not exported to the environment for child processes.</p>
|
|
<h4 id="if-present"><code>if-present</code></h4>
|
|
<ul>
|
|
<li>Default: false</li>
|
|
<li>Type: Boolean</li>
|
|
</ul>
|
|
<p>If true, npm will not exit with an error code when <code>run-script</code> is invoked
|
|
for a script that isn't defined in the <code>scripts</code> section of <code>package.json</code>.
|
|
This option can be used when it's desirable to optionally run a script when
|
|
it's present and fail if the script fails. This is useful, for example, when
|
|
running scripts that may only apply for some builds in an otherwise generic
|
|
CI setup.</p>
|
|
<p>This value is not exported to the environment for child processes.</p>
|
|
<h4 id="ignore-scripts"><code>ignore-scripts</code></h4>
|
|
<ul>
|
|
<li>Default: false</li>
|
|
<li>Type: Boolean</li>
|
|
</ul>
|
|
<p>If true, npm does not run scripts specified in package.json files.</p>
|
|
<p>Note that commands explicitly intended to run a particular script, such as
|
|
<code>npm start</code>, <code>npm stop</code>, <code>npm restart</code>, <code>npm test</code>, and <code>npm run-script</code>
|
|
will still run their intended script if <code>ignore-scripts</code> is set, but they
|
|
will <em>not</em> run any pre- or post-scripts.</p>
|
|
<h4 id="foreground-scripts"><code>foreground-scripts</code></h4>
|
|
<ul>
|
|
<li>Default: false</li>
|
|
<li>Type: Boolean</li>
|
|
</ul>
|
|
<p>Run all build scripts (ie, <code>preinstall</code>, <code>install</code>, and <code>postinstall</code>)
|
|
scripts for installed packages in the foreground process, sharing standard
|
|
input, output, and error with the main npm process.</p>
|
|
<p>Note that this will generally make installs run slower, and be much noisier,
|
|
but can be useful for debugging.</p>
|
|
<h4 id="script-shell"><code>script-shell</code></h4>
|
|
<ul>
|
|
<li>Default: '/bin/sh' on POSIX systems, 'cmd.exe' on Windows</li>
|
|
<li>Type: null or String</li>
|
|
</ul>
|
|
<p>The shell to use for scripts run with the <code>npm exec</code>, <code>npm run</code> and <code>npm init <package-spec></code> commands.</p>
