JavaScript integration the main theme at AJAXWorld

By Alex Handy

October 22, 2008 — (Page 1 of 2)
With a new version of Silverlight, updated Adobe AIR and Flex tools, and an ever-expanding storm of interest in dynamic languages, you'd think the hype around AJAX would have died down a bit by now. But at the AJAXWorld RIA Conference & Expo in San Jose on Oct. 20, developers learned that JavaScript is like the color black or a sprig of parsley: It goes with anything.

Conferences focused on mixing AJAX code with existing and future application architectures. Those topics ran the gamut from building solid software foundations to assembling cloud computing platforms.

Chris Keene, CEO of WaveMaker, said that cloud computing doesn't change much for AJAX itself, but it does fundamentally change the way JavaScript applications must be architected. As an example, he discussed Google Gadgets, tiny JavaScript applications that can be embedded in existing Web pages to do everything from check eBay sales to monitoring user errors. The toughest thing about writing a gadget, said Keene, is testing it properly.

“If you're doing a Google Gadget that displays eBay items for sale, being able to test all the possible combinations of data that might get jammed into your gadget is almost impossible," said Keene. "Testing gets more difficult. So Google has done things like limited the total size of the payload for a widget to 20[Kb] to try and address some of those scaling issues. One Google Gadget I heard about went to the No. 9 of Google's internal traffic site in two minutes. You update a Google Gadget, you unpause it."

With no actual site to call home, such embeddable applications can propagate anywhere on the Internet. If those gadgets have a central location where they are doing processing, scaling can become an issue that can only be solved by proper architecture, said Keene.

Keene focused specifically on hosting applications in Amazon's Elastic Compute Cloud (EC2). He said that there are a number of issues that developers must overcome in such an application, none the least of which is e-mail.
