<pre lang="bash"><code>npm ls [[<@scope>/]<pkg> ...]
aliases: list, la, ll
</code></pre>
<h3 id="description">Description</h3>
<p>This command will print to stdout all the versions of packages that are
installed, as well as their dependencies when <code>--all</code> is specified, in a
tree structure.</p>
<p>Note: to get a “bottoms up” view of why a given package is included in the
tree at all, use <a href="../commands/npm-explain.html"><code>npm explain</code></a>.</p>
<p>Positional arguments are <code>name@version-range</code> identifiers, which will limit
the results to only the paths to the packages named. Note that nested
packages will <em>also</em> show the paths to the specified packages. For
example, running <code>npm ls promzard</code> in npm’s source tree will show:</p>
<pre lang="bash"><code>npm@7.15.1 /path/to/npm
└─┬ init-package-json@0.0.4
└── promzard@0.1.5
</code></pre>
<p>It will print out extraneous, missing, and invalid packages.</p>
<p>If a project specifies git urls for dependencies these are shown
in parentheses after the name@version to make it easier for users to
recognize potential forks of a project.</p>
<p>The tree shown is the logical dependency tree, based on package
dependencies, not the physical layout of your <code>node_modules</code> folder.</p>
<p>When run as <code>ll</code> or <code>la</code>, it shows extended information by default.</p>
<h3 id="note-design-changes-pending">Note: Design Changes Pending</h3>
<p>The <code>npm ls</code> command’s output and behavior made a <em>ton</em> of sense when npm
created a <code>node_modules</code> folder that naively nested every dependency. In
such a case, the logical dependency graph and physical tree of packages on
disk would be roughly identical.</p>
<p>With the advent of automatic install-time deduplication of dependencies in
npm v3, the <code>ls</code> output was modified to display the logical dependency
graph as a tree structure, since this was more useful to most users.
However, without using <code>npm ls -l</code>, it became impossible show <em>where</em> a
package was actually installed much of the time!</p>
<p>With the advent of automatic installation of <code>peerDependencies</code> in npm v7,
this gets even more curious, as <code>peerDependencies</code> are logically
“underneath” their dependents in the dependency graph, but are always
physically at or above their location on disk.</p>
<p>Also, in the years since npm got an <code>ls</code> command (in version 0.0.2!),
dependency graphs have gotten much larger as a general rule. Therefore, in
order to avoid dumping an excessive amount of content to the terminal, <code>npm ls</code> now only shows the <em>top</em> level dependencies, unless <code>--all</code> is
provided.</p>
<p>A thorough re-examination of the use cases, intention, behavior, and output
of this command, is currently underway. Expect significant changes to at
least the default human-readable <code>npm ls</code> output in npm v8.</p>
<h3 id="configuration">Configuration</h3>
<!-- raw HTML omitted -->
<!-- raw HTML omitted -->
<h4 id="all"><code>all</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>When running <code>npm outdated</code> and <code>npm ls</code>, setting <code>--all</code> will show all
outdated or installed packages, rather than only those directly depended
upon by the current project.</p>
<h4 id="json"><code>json</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Whether or not to output JSON data, rather than the normal output.</p>
<p>Not supported by all npm commands.</p>
<h4 id="long"><code>long</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Show extended information in <code>ls</code>, <code>search</code>, and <code>help-search</code>.</p>
<h4 id="parseable"><code>parseable</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Output parseable results from commands that write to standard output. For
<code>npm search</code>, this will be tab-separated table format.</p>
<h4 id="global"><code>global</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>Operates in “global” mode, so that packages are installed into the <code>prefix</code>
folder instead of the current working directory. See
<a href="../configuring-npm/folders.html">folders</a> for more on the differences in behavior.</p>
<ul>
<li>packages are installed into the <code>{prefix}/lib/node_modules</code> folder, instead
of the current working directory.</li>
<li>bin files are linked to <code>{prefix}/bin</code></li>
<li>man pages are linked to <code>{prefix}/share/man</code></li>
</ul>
<h4 id="depth"><code>depth</code></h4>
<ul>
<li>Default: <code>Infinity</code> if <code>--all</code> is set, otherwise <code>1</code></li>
<li>Type: null or Number</li>
</ul>
<p>The depth to go when recursing packages for <code>npm ls</code>.</p>
<p>If not set, <code>npm ls</code> will show only the immediate dependencies of the root
project. If <code>--all</code> is set, then npm will show all dependencies by default.</p>
<h4 id="omit"><code>omit</code></h4>
<ul>
<li>Default: ‘dev’ if the <code>NODE_ENV</code> environment variable is set to
‘production’, otherwise empty.</li>
<li>Type: “dev”, “optional”, or “peer” (can be set multiple times)</li>
</ul>
<p>Dependency types to omit from the installation tree on disk.</p>
<p>Note that these dependencies <em>are</em> still resolved and added to the
<code>package-lock.json</code> or <code>npm-shrinkwrap.json</code> file. They are just not
physically installed on disk.</p>
<p>If a package type appears in both the <code>--include</code> and <code>--omit</code> lists, then
it will be included.</p>
<p>If the resulting omit list includes <code>'dev'</code>, then the <code>NODE_ENV</code> environment
variable will be set to <code>'production'</code> for all lifecycle scripts.</p>
<h4 id="link"><code>link</code></h4>
<ul>
<li>Default: false</li>
<li>Type: Boolean</li>
</ul>
<p>If true, then local installs will link if there is a suitable globally
installed package.</p>
<p>Note that this means that local installs can cause things to be installed
into the global space at the same time. The link is only done if one of the
two conditions are met:</p>
<ul>
<li>The package is not already installed globally, or</li>
<li>the globally installed version is identical to the version that is being
installed locally.</li>
</ul>
<p>When used with <code>npm ls</code>, only show packages that are linked.</p>
<h4 id="unicode"><code>unicode</code></h4>
<ul>
<li>Default: false on windows, true on mac/unix systems with a unicode locale,
as defined by the <code>LC_ALL</code>, <code>LC_CTYPE</code>, or <code>LANG</code> environment variables.</li>
<li>Type: Boolean</li>
</ul>
<p>When set to true, npm uses unicode characters in the tree output. When
false, it uses ascii characters instead of unicode glyphs.</p>
<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 to selecting all of the
nested workspaces)</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: false</li>
<li>Type: Boolean</li>
</ul>
<p>Enable running a command in the context of <strong>all</strong> the configured
workspaces.</p>
<p>This value is not exported to the environment for child processes.</p>
