As I started working with the Ext JS framework I didn’t know exactly what to expect. Now I’ve done some experiences with the framework. I want to show the advantages and disadvantages of the ext framework in the current free available version 2.2.

Advantages:

  • Easy to learn
  • Well documented
  • Great community providing help if necessary
  • Premium support available
  • Progress is noticeable
  • Nice look (different skins available)
  • Nicely extendable by ‘Extensions’; see MindPatterns blog
  • Works without any client side application exept a browser (no flash-plugin or something similar required)

Disadvantages:

  • A lot of reported bugs
  • Complex structures of UI elements are not working all the time
  • Some license problems
  • Some bugs haven’t been fixed but rather worked around

Finally the Ext JS framework is a very nice looking, young framework for web based applications. It’s possible to use the framework with all the available server side languages. Support is also available for open source developers for free. I would recommend this framework for developers that want to work with a growing framework. But I you don’t have the time for fixing some bugs take care of the early version of the framework and use only de basic features. I’ve worked about six months up to now and I am really very satisfied of the framework.

Now I want to refer to a developer who has written some very nice extensions for the Ext framework which I’m currently using in my projects. Check out MindPatterns blog and see the power of Ext for yourself.
