The product constitutes the "world's first HTML5 mobile web framework," said Ed Spencer, senior software architect at Sencha, at the Sencha Conference 2010. HTML5 is a web development specification and related technologies for building modern standards-based web applications with capabilities such as multimedia.
Sencha Touch features a theming system to change an application's appearance with a few lines of code, Sencha said. Resolution independence technology in the product allows consistent display on devices with different pixel densities. Data management classes and a touch event system allow developers to focus on their application rather than on eccentricities of mobile platforms.
Sencha Touch 1.0 had been in a beta test period since June. It supports development for platforms including Google Android and Apple iOS. A roadmap detailed for the product has RIM Blackberry support being added in Sencha Touch 1.1 in the first quarter of 2011.
Sencha had charged $99 for the beta release of Sensa Touch but decided to drop this fee. "We want this to be the de facto standard that everyone uses," for mobile development, Spencer said. The company sells support services for Sencha Touch as well as development frameworks such as Ext JS.
Sencha will compete with others in the mobile application development space, such as Rhomobile and Appcelerator. Rhomobile's Rhodes framework and Appcelerator's Titanium framework both supports native development
The upcoming Ext JS 4 release, or Ext 4, features improvements in stability, speed and flexibility. Ext JS is for development of desktop applications.
"Speed is very important to us and, with Ext 4, is one of our top priorities," said Spencer. Continual performance testing for code boosts framework speed. A new layout engine also assists with performance and flexibility. Also, unit tests offer 90 percent of code coverage, providing stability, Spencer said. He also cited documentation improvements. "With Ext 4, we have the best documentation we've ever created, and not by a short way, by a long way."
Also featured are improvements for charting and disabled accessibility. Ext JS 4 is set for a beta release in six weeks, with general availability due on February 28.
Sencha also plans to offer an automated testing tool called Visual QA, which is now being used internally at the company.
