Javascript Toolkit Comparison

Javascript Toolkit Comparison - Archived Portal Exploration - JA-SIG Wiki

With the increased demand of "WEB 2.0" features such as drag 'n drop, AJAX, and client-side processing, the need for a robust javascript library in uPortal 3 becomes more and more obvious. These pages are dedicated to discussion around the many available javascript libraries*. I will focus mainly on the 6 with the most hype currently: Prototype, Dojo, Mochikit, Yahoo! UI, Google, and JQuery. Feel free to add any others which might be worth considering. For a good article reviewing some of these libraries, visit sitepoint.com.

Other JS libraries not evaluated here:

• Zimbra Ajax TK (Kabuki)
• DWR

* I will assume that the terms library, toolkit, and framework are inter-changeable. This may merit its own discussion page, just not here.
** Google offers its Java libraries under Apache license, but its Java to Javascript converter is proprietary.
