<div id="_content"><h3 id="description">Description</h3>
<p><strong>Workspaces</strong> is a generic term that refers to the set of features in the
npm cli that provides support for managing multiple packages from your local
file system from within a singular top-level, root package.</p>
<p>This set of features makes up for a much more streamlined workflow handling
linked packages from the local file system. It automates the linking process
as part of <code>npm install</code> and removes the need to manually use <code>npm link</code> in
order to add references to packages that should be symlinked into the current
<code>node_modules</code> folder.</p>
<p>We also refer to these packages being auto-symlinked during <code>npm install</code> as a
single <strong>workspace</strong>, meaning it's a nested package within the current local
file system that is explicitly defined in the <a href="../configuring-npm/package-json#workspaces.html"><code>package.json</code></a>
<code>workspaces</code> configuration.</p>
<h3 id="defining-workspaces">Defining workspaces</h3>
<p>Workspaces are usually defined via the <code>workspaces</code> property of the
<a href="../configuring-npm/package-json#workspaces.html"><code>package.json</code></a> file, e.g:</p>
<pre><code class="language-json">{
  "name": "my-workspaces-powered-project",
  "workspaces": [
    "packages/a"
  ]
}
</code></pre>
<p>Given the above <code>package.json</code> example living at a current working
directory <code>.</code> that contains a folder named <code>packages/a</code> that itself contains
a <code>package.json</code> inside it, defining a Node.js package, e.g:</p>
<pre><code>.
+-- package.json
`-- packages
   +-- a
   |   `-- package.json
</code></pre>
<p>The expected result once running <code>npm install</code> in this current working
directory <code>.</code> is that the folder <code>packages/a</code> will get symlinked to the
<code>node_modules</code> folder of the current working dir.</p>
<p>Below is a post <code>npm install</code> example, given that same previous example
structure of files and folders:</p>
<pre><code>.
+-- node_modules
|  `-- a -&gt; ../packages/a
+-- package-lock.json
+-- package.json
`-- packages
   +-- a
   |   `-- package.json
</code></pre>
<h3 id="getting-started-with-workspaces">Getting started with workspaces</h3>
<p>You may automate the required steps to define a new workspace using
<a href="../commands/npm-init.html">npm init</a>. For example in a project that already has a
<code>package.json</code> defined you can run:</p>
<pre><code>npm init -w ./packages/a
</code></pre>
<p>This command will create the missing folders and a new <code>package.json</code>
file (if needed) while also making sure to properly configure the
<code>"workspaces"</code> property of your root project <code>package.json</code>.</p>
<h3 id="adding-dependencies-to-a-workspace">Adding dependencies to a workspace</h3>
<p>It's possible to directly add/remove/update dependencies of your workspaces
using the <a href="../using-npm/config#workspace.html"><code>workspace</code> config</a>.</p>
<p>For example, assuming the following structure:</p>
<pre><code>.
+-- package.json
`-- packages
   +-- a
   |   `-- package.json
   `-- b
       `-- package.json
</code></pre>
<p>If you want to add a dependency named <code>abbrev</code> from the registry as a
dependency of your workspace <strong>a</strong>, you may use the workspace config to tell
the npm installer that package should be added as a dependency of the provided
workspace:</p>
<pre><code>npm install abbrev -w a
</code></pre>
<p>Note: other installing commands such as <code>uninstall</code>, <code>ci</code>, etc will also
respect the provided <code>workspace</code> configuration.</p>
<h3 id="using-workspaces">Using workspaces</h3>
<p>Given the <a href="https://nodejs.org/dist/latest-v14.x/docs/api/modules.html#modules_all_together">specifics of how Node.js handles module resolution</a> it's possible to consume any defined workspace
by its declared <code>package.json</code> <code>name</code>. Continuing from the example defined
above, let's also create a Node.js script that will require the workspace <code>a</code>
example module, e.g:</p>
<pre><code>// ./packages/a/index.js
module.exports = 'a'

// ./lib/index.js
const moduleA = require('a')
console.log(moduleA) // -&gt; a
</code></pre>
<p>When running it with:</p>
<p><code>node lib/index.js</code></p>
<p>This demonstrates how the nature of <code>node_modules</code> resolution allows for
<strong>workspaces</strong> to enable a portable workflow for requiring each <strong>workspace</strong>
in such a way that is also easy to <a href="../commands/npm-publish.html">publish</a> these
nested workspaces to be consumed elsewhere.</p>
<h3 id="running-commands-in-the-context-of-workspaces">Running commands in the context of workspaces</h3>
<p>You can use the <code>workspace</code> configuration option to run commands in the context
of a configured workspace.
Additionally, if your current directory is in a workspace, the <code>workspace</code>
configuration is implicitly set, and <code>prefix</code> is set to the root workspace.</p>
<p>Following is a quick example on how to use the <code>npm run</code> command in the context
of nested workspaces. For a project containing multiple workspaces, e.g:</p>
<pre><code>.
+-- package.json
`-- packages
   +-- a
   |   `-- package.json
   `-- b
       `-- package.json
</code></pre>
<p>By running a command using the <code>workspace</code> option, it's possible to run the
given command in the context of that specific workspace. e.g:</p>
<pre><code>npm run test --workspace=a
</code></pre>
<p>You could also run the command within the workspace.</p>
<pre><code>cd packages/a &amp;&amp; npm run test
</code></pre>
<p>Either will run the <code>test</code> script defined within the
<code>./packages/a/package.json</code> file.</p>
<p>Please note that you can also specify this argument multiple times in the
command-line in order to target multiple workspaces, e.g:</p>
<pre><code>npm run test --workspace=a --workspace=b
</code></pre>
<p>Or run the command for each workspace within the 'packages' folder:</p>
<pre><code>npm run test --workspace=packages
</code></pre>
<p>It's also possible to use the <code>workspaces</code> (plural) configuration option to
enable the same behavior but running that command in the context of <strong>all</strong>
configured workspaces. e.g:</p>
<pre><code>npm run test --workspaces
</code></pre>
<p>Will run the <code>test</code> script in both <code>./packages/a</code> and <code>./packages/b</code>.</p>
<p>Commands will be run in each workspace in the order they appear in your <code>package.json</code></p>
<pre><code>{
  "workspaces": [ "packages/a", "packages/b" ]
}
</code></pre>
<p>Order of run is different with:</p>
<pre><code>{
  "workspaces": [ "packages/b", "packages/a" ]
}
</code></pre>
<h3 id="ignoring-missing-scripts">Ignoring missing scripts</h3>
<p>It is not required for all of the workspaces to implement scripts run with the <code>npm run</code> command.</p>
<p>By running the command with the <code>--if-present</code> flag, npm will ignore workspaces missing target script.</p>
<pre><code>npm run test --workspaces --if-present
</code></pre>
