WordPress Plugin: Google AJAX Libraries API

Important: This plugin is no longer being updated. It has been superceded by the good work of Jason Penney with his Use Google Libraries WordPress plugin which uses code based on this plugin. I recommend that you use his plugin from now on.


This plugin replaces the most common JavaScript libraries in WordPress with the corresponding files on Google AJAX Libraries.

“The AJAX Libraries API is a content distribution network and loading architecture for the most popular open source JavaScript libraries.”

Note that this plugin does not actually replace or remove any files from your WordPress installation. It simply replaces any references to them with references to the corresponding files on Google AJAX Libraries.


  1. Unzip the ZIP file and drop the folder straight into your wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. That’s it!

Which Libraries are Supported?

The current version of the plugin supports the following JavaScript libraries:

  • jQuery
  • Prototype
  • Scriptaculous
  • MooTools
  • Dojo


ZIP file from downloads.wordpress.org
You should use the ‘Use Google Libraries’ WordPress plugin instead now.

  1. Otto, that’s worth knowing. They might have some other sub-libraries (is that what they’re called?) on there too. I’ll have a dig around and update the plugin.
