<h1><a href="../cli/npm-cache.html">npm-cache</a></h1> <p>Manipulates packages cache</p>

<h2 id="synopsis">SYNOPSIS</h2>
|
|
<pre><code>npm cache add <tarball file>
|
|
npm cache add <folder>
|
|
npm cache add <tarball url>
|
|
npm cache add <name>@<version>
|

aliases: npm cache clear, npm cache rm
|
|
</code></pre><h2 id="description">DESCRIPTION</h2>
|
|
<p>Used to add, list, or clean the npm cache folder.</p>
|
|
<ul>
|
|
<li><p>add:
|
|
Add the specified package to the local cache. This command is primarily
|
|
intended to be used internally by npm, but it can provide a way to
|
|
add data to the local installation cache explicitly.</p>
|
|
</li>
|
|
<li><p>ls:
|
|
Show the data in the cache. Argument is a path to show in the cache
|
|
folder. Works a bit like the <code>find</code> program, but limited by the
|
|
<code>depth</code> config.</p>
|
|
</li>
|
|
<li><p>clean:
|
|
Delete data out of the cache folder. If an argument is provided, then
|
|
it specifies a subpath to delete. If no argument is provided, then
|
|
the entire cache is deleted.</p>
|
|
</li>
|
|
</ul>
|
|
<h2 id="details">DETAILS</h2>
|
|
<p>npm stores cache data in the directory specified in <code>npm config get cache</code>.
|
|
For each package that is added to the cache, three pieces of information are
|
|
stored in <code>{cache}/{name}/{version}</code>:</p>
|
|
<ul>
|
|
<li>.../package/package.json:
|
|
The package.json file, as npm sees it.</li>
|
|
<li>.../package.tgz:
|
|
The tarball for that version.</li>
|
|
</ul>
|
|
<p>Additionally, whenever a registry request is made, a <code>.cache.json</code> file
|
|
is placed at the corresponding URI, to store the ETag and the requested
|
|
data. This is stored in <code>{cache}/{hostname}/{path}/.cache.json</code>.</p>
|
|
<p>Commands that make non-essential registry requests (such as <code>search</code> and
|
|
<code>view</code>, or the completion scripts) generally specify a minimum timeout.
|
|
If the <code>.cache.json</code> file is younger than the specified timeout, then
|
|
they do not make an HTTP request to the registry.</p>
|
|
<h2 id="configuration">CONFIGURATION</h2>
|
|
<h3 id="cache">cache</h3>
|
|
<p>Default: <code>~/.npm</code> on Posix, or <code>%AppData%/npm-cache</code> on Windows.</p>
|
|
<p>The root cache folder.</p>
