This library packages ExtJS for Fanstatic.
This requires integration between your web framework and Fanstatic, and making sure that the original resources (shipped in the resources directory in js.extjs) are published to some URL.
How to use?
You can import various resources from js.extjs and need it where you want these resources to be included on a page. The two basic resource sets that you'll probably need are these
>>> from js import extjs
You can also include individual resources
>>> from js.extjs import adapter, extjs, ux
You can also import themes
>>> from js.extjs import theme
