View Full Version : ExtJS Mobile Development

18 Feb 2010, 6:17 PM
Hello everyone,

I'm interested in developing a mobile application using ExtJS (I really like how ExtJS uses custom objects & events). The only downside is that ext-all.js is over 634KB which might take too long to download over 3G networks. Since I'm only interested in extending the Ext.util.Observable class, is it possible to edit the library down to the bare neccessities? Has anyone attempted this before?

Thanks in advance,

-Ted Godwin

There are some other threads regarding mobile dev. Also, you can build a stripped down version of the library using JSBuilder. Also if you're not using any Components at all, you might just be able use Ext Core, rather than the full framework.

If developing for mobile, why not use Sencha Touch which has much the same core features as Ext JS except its designed to work on mobile devices?

Thanks for everyone's response. This question was posted last year before Sencha's big debut.
