View Full Version : Ext-Core to Bootstrap ExtJS

27 Feb 2010, 5:20 PM
Hi all... I've been using ExtJs for some while now and I love it. But we've gotten to a point where we are trying to eek every little bit of performance possible out of our page render times. and as great as the ExtJs framework is, it is a huge performance hit due to its size. I'm interested to know if I should anticipate any problems on using Ext-core for initial loading (most page wouldn't need much more than ext-core to initiate menu's and what not) and then later in the lifecycle dynamically bootstrap the rest of the ExtJs framework so that I can benefit from Ext.Direct, Ext.Window, etc.... any help on the matter would be appreciated.

This is actually something we've been looking at in the last week. Ext Core is just a subset of Ext JS, so it's possible to split the files up into a Core file and a non-Core file - you can load the Core file and then pull down non-Core at any future point.

Initial tests seem to show this working well - I'll update this thread as soon as we have a public solution.

This would be great. I might use the global google ajax copy of core if this goes forward (and initExtCss used addClass rather than directly manipulating as per this thread (http://www.extjs.com/forum/showthread.php?t=65106)).
