Offload open source static assets to the free, public CDN.

Milan Dinić

commonWP is a plugin that enables usage of free, public CDN (<a href="https://www.jsdelivr.com/" rel="nofollow ugc">jsDelivr</a>) for open source JavaScript and CSS files. Those files are:
<ul>
<li>All files from WordPress core, unless development version of WordPress is used.</li>
<li>All files from plugins hosted by WordPress.org Plugins Repository, unless author of specific plugin doesn’t use <a href="https://developer.wordpress.org/plugins/wordpress-org/how-to-use-subversion/#tagging-new-versions" rel="nofollow ugc">SVN tags for releasing</a>.</li>
<li>All files from themes hosted by WordPress.org Themes Repository.</li>
<li>All files from plugins and themes hosted on <a href="https://github.com/" rel="nofollow ugc">GitHub</a> that support <a href="https://github.com/afragen/github-updater" rel="nofollow ugc">GitHub Updater</a>.</li>
<li>All files marked as available on <a href="https://www.npmjs.com/" rel="nofollow ugc">npm</a> in any type of theme, plugin, or MU plugin.</li>
</ul>
It aims to be both lightweight and very secure. The approach used in this plugin is safer then in any other plugin that enables usage of any CDN. First, commonWP will only rewrite file to point to one on jsDelivr if that remote file is identical to local one. Second, during comparison, it generates <a href="https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity" rel="nofollow ugc">subresource identity hash</a> of remote jsDelivr file and includes that hash in page’s source code so browser won’t load remote file if it doesn’t have exactly the same hash.
There are no any settings. After activation, it will fill up its cache in the background, and that may take some time depending on number of resources site uses.

commonWP

Very well written plugin! The easiest and safest way to load your common assets through jsdelivr. Every site should be using it to help the cache.

Easy to use, just activate it and you are done. Plenty of hooks to override any features that you need.

Bonus points for providing a WP-CLI interface.
