Sencha Ext JS provides a complete object-oriented framework for creating a desktop-like application that runs in a web browser or packaged as a native application.

Notable Historical Events

  • 01-Jul-2015: With Ext JS 6, Sencha introduces a single framework for creating applications that run across all types of devices, from phones to tablets to desktops. This move combines the legacy Touch framework into the same project structure as Ext JS allowing for the sharing of resources.

  • 15-Apr-2014: Along with the release of version 5.0 Sencha Inc. officially dropped support for Internet Explorer versions 6 & 7 and only support 8 in "standards" mode. This marks a shift in favour of modern web-standards.

  • 15-Jun-2010: The merger of ExtJS with JQTouch and Raphaël was announced forming a new organisation called Sencha Inc. Ext JS continues to be available as a main product on the Sencha website together with Sencha Touch, Sencha GWT, Sencha Architect, Sencha Animator and Ext Core.
