The eZ JS Core extension provides a framework for using Ajax, JavaScript and CSS to allow easier client/server integrations using yui 3.0 and/or jQuery.

Main eZ JS Core features

• JavaScript / CSS file dependency handling which enables developers to define the files to load per code block. This supports the loading of only those JavaScript and CSS files that are needed for a particular page.
• Packing JavaScript files and CSS files into a single JavaScript or CSS file and thus minimizing the total. This improves the performance by reducing the number and sizes of requests.
• A framework is offered to communicate between client and server using the YUI and jQuery libraries. Note that with some extra code, any JavaScript library can be supported. This includes wrappers for the respective JavaScript IO calls, and a server-side router framework for the Ajax requests.
• Functions (and template operators) to encode eZ Publish nodes and variables to JSON and XML.
