GeoExt can be used just like any other Ext component, and applications making use of GeoExt also profit from Ext JS enhancements like charting, a harmonized API with Sencha Touch and a sophisticated single-file build tool.

A lot of the code and structural decisions for GeoExt 3 came from a code sprint in Bonn. 9 developers gathered there from 2015-06-17 to 2015-06-19. We are deeply grateful that our sponsors helped to start GeoExt 3.

Now, have a look at the examples below, read the API documentation, the API documentation (including ExtJS classes for versions up to v6) or checkout the code.
