Big Data Grids

Sencha Ext JS provides rich capabilities for enterprise developers with its improved big data grids. High data point applications, such as financial or insurance applications can take advantage of these new capabilities to deliver more powerful and sophisticated user experiences.

Plugin-free Charting

No plugins, no problem. Don’t let proprietary browser plugins get in the way of delivering eye-catching charts. Ext JS 4 delivers the most advanced charting and graphing capabilities of any JavaScript framework, delivering pixel perfect visuals on any browser on any operating system. Leveraging SVG and VML, Ext JS 4’s new charting package lets developers design and program their graphs once and never have to worry if they’ll work.

Clean Component Model

A core strength of Ext JS is its component design. You can easily extend the default components to meet your needs, and extensions will be encapsulated within just those components. As a result, your development teams can create even the largest applications without stepping on each other’s code.

Cross Platform Browser Compatibility

Ext JS 4 lets developers deliver on an incredible variety of browsers and on more operating systems using the same code — over ten years of browsers in one release. On modern browsers, Ext JS 4 utilizes HTML5 features and falls back to alternatives on older browsers. Whether you’re using Ext JS’ built-in UI components, using the new Charting package, or theming your application, Ext JS 4 makes it easy to build an app that gives you the power of the web regardless of what browser your customer uses.

Ext JS supports all major web browsers including:

• Internet Explorer 6+
• Firefox 3.6+ (PC, Mac)
• Safari 4+
• Chrome 10+
• Opera 11+ (PC, Mac)
