As we prepare for Ext JS 5 GA, it’s time for all of us to start reviewing our codebases as well as our test coverage to make sure our applications are well tested before the upgrade. In this guest blog post, Mats Bryntse shows you how to get started, even if you have no tests. You can start today and write a few Siesta smoke tests to help you get some assurance that your applications are working on the new version of Ext JS.
Ext JS 5 delivers some exciting improvements for you to use in your application architecture. We have added support for ViewModels and MVVM as well as ViewControllers to enhance MVC applications. Best of all, these choices are not mutually exclusive, so you can introduce these features incrementally or even blend them. Download Ext JS 5 to try them out.
Application architecture is as much about providing structure and consistency as it is about actual classes and framework code, and building a good architecture unlocks a number of important benefits. In Ext JS 5, we’re adding optional support for the MVVM architectural pattern. Although MVC and MVVM are very similar software patterns, using MVVM has some specific benefits that can vastly reduce the amount of application logic developers need to write. Learn how and when to use the MVC and MVVM patterns.

Prior to version 5, Ext JS was designed exclusively for use on desktop devices with traditional mouse input. With the release of Ext JS 5 beta, we’ve added support for touch input as well, which allows Ext JS to be used on a larger selection of devices, primarily tablets, but also laptops with touch-screens. In this article, you’ll learn how the framework handles touch events and event normalization between devices. Download the Ext JS 5 beta and check it out.
Sencha Ext JS 5 beta is available for public access and evaluation. This release includes touch support, two-way data binding, grid gadgets, touch-optimized charts, routing and more.
