<h2 id="synopsis">SYNOPSIS</h2>
<pre><code>npm prune [[<@scope>/]<pkg>...] [--production] [--dry-run] [--json]</code></pre><h2 id="description">DESCRIPTION</h2>
<p>This command removes "extraneous" packages. If a package name is
provided, then only packages matching one of the supplied names are
removed.</p>
<p>Extraneous packages are packages that are not listed on the parent
package's dependencies list.</p>
<p>If the <code>--production</code> flag is specified or the <code>NODE_ENV</code> environment
variable is set to <code>production</code>, this command will remove the packages
specified in your <code>devDependencies</code>. Setting <code>--no-production</code> will
negate <code>NODE_ENV</code> being set to <code>production</code>.</p>
<p>If the <code>--dry-run</code> flag is used then no changes will actually be made.</p>
<p>If the <code>--json</code> flag is used then the changes <code>npm prune</code> made (or would
have made with <code>--dry-run</code>) are printed as a JSON object.</p>
<p>In normal operation with package-locks enabled, extraneous modules are
pruned automatically when modules are installed and you'll only need
this command with the <code>--production</code> flag.</p>
<p>If you've disabled package-locks then extraneous modules will not be removed
and it's up to you to run <code>npm prune</code> from time-to-time to remove them.</p>
