The CDN caches files based on their permanent URL, which includes the
|
|
|
|
npm package version. This works because npm does not allow package
|
|
|
|
authors to overwrite a package that has already been published with a
|
|
|
|
different one at the same version number.
|
|
|
|
</p>
|
|
|
|
<p>
|
|
|
|
URLs that do not specify a package version number redirect to one that
|
|
|
|
does. This is the <code>latest</code> version when no version is
|
|
|
|
specified, or the <code>maxSatisfying</code> version when a{' '}
|
|
|
|
<a href="https://github.com/npm/node-semver">semver version</a> is
|
|
|
|
given. Redirects are cached for 5 minutes.
|
|
|
|
</p>
|
|
|
|
<p>
|
|
|
|
Browsers are instructed (via the <code>Cache-Control</code> header) to
|
|
|
|
cache assets for 1 year.

For npm package authors, unpkg relieves the burden of publishing your
|
|
|
|
code to a CDN in addition to the npm registry. All you need to do is
|
|
|
|
include your <a href="https://github.com/umdjs/umd">UMD</a> build in
|
|
|
|
your npm package (not your repo, that's different!).
|
|
|
|
</p>
|
|
|
|
|
|
|
|
<p>You can do this easily using the following setup:</p>
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
<li>
|
|
|
|
Add the <code>umd</code> (or <code>dist</code>) directory to your{' '}
|
|
|
|
<code>.gitignore</code> file
|
|
|
|
</li>
|
|
|
|
<li>
|
|
|
|
Add the <code>umd</code> directory to your{' '}
|
|
|
|
<a href="https://docs.npmjs.com/files/package.json#files">
|
|
|
|
files array
|
|
|
|
</a>{' '}
|
|
|
|
in
|
|
|
|
<code>package.json</code>
|
|
|
|
</li>
|
|
|
|
<li>
|
|
|
|
Use a build script to generate your UMD build in the{' '}
|
|
|
|
<code>umd</code> directory when you publish
|
|
|
|
</li>
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
<p>
|
|
|
|
That's it! Now when you <code>npm publish</code> you'll have
|
|
|
|
a version available on unpkg as well.
