There has been quite a bit of chatter lately on the change to Ext JS licensing. Working for a Ajax library/framework/platform vendor myself, I thought I would review the GPL and see how it would relate to an Ajax library. The GPL license was interesting and long. One thing with all licenses is that depending on what you are doing they apply differently.� GPL makes sense for lots of software, MySQL uses the license, the Java source is also GPL.

Even though that feature is still in there and very useful, the project has continued to evolve. Next, I added the JavaScript metricing that makes it possible to find performance bottlenecks with large Ajax application using any web browser.

Over the last year I have talked at many conferences about ways to optimize Ajax applications; reduce the number of requests and reduce the size of the requests. Many others out there have done even more to educate people on ways to do this using a variety of techniques. The issue with using many of the techniques, they are almost always command line driven. I’m a IDE user, so things not integrated into Eclipse are a pain in the ass. Read more…
