After implementing a whole application with Ext JS, and after presenting also in this blog basic overview of the prototype and jquery javascript frameworks and given a small idea of the functionalities of qooxdoo (and a little overview of QWT), I want to give a more or less thorough view of all the features of this quality framework. In a later entry, I will give a thorough presentation of the relations between GWT and Ext JS.
It is important to notice, that unlike other frameworks the extJS framework does not have a licence mechanism which is very suitable for enterprise application which need to be kept closed source, unless you are ready to pay licence fees to the company owning the code of extJS. However, the core of ext JS is proposed under an LGPL licence, so it can still be used in closed source development.
I first list the main features of extJS, then I go in a little more details for each of these points:
- Namespace functionalities
- DOM elements manipulation Utilities
- Data Manipulation Utilities
- Data Store functionalities
- Ajax request functionalities
- an extended set of application widgets: trees, tables form, charts
- a complete RIA framework, with menus, drag and drop,....

This is presented in this entry. Namespaces makes it easy it construct more modular applications.
