Asynchronous Javascript

This plugin is meant to be a drop-in to your wordpress installation with no additional configuration. The goals/features of this plugin are:

• Load javascript files in an asynchronous manner to improve time to DomReady/OnLoad
• Use existing wordpress APIs for backwards compatability and prevent coupling to this plugin
• Leverage dependency model wordpress provides for assets to improve loading performance

Please submit bugs or contributions to the github location and not here on wordpress’ system:

Incompatibility

This plugin will not work out the box with the following plugins (unless they are modified to support asynchronous loading).

• Jetpack by WordPress.com (social plugin)
• WP Most Popular

1. Upload asynchronous-javascript folder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress

Is there any potential problems with other plugins?

As long as those plugins are using the built-in wordpress script queuing and not attempting to output scripts manually (such as invoking wp_print_scripts()), you should have no problems. If you find plugins that don’t work properly (or without modifications), let me know and I will maintain an incompatibility list.
