What Javascript frameworks have good performance on Android?

[Daniel Trebbien]

Of the many choices of Javascript libraries and frameworks for browsers, which ones have good performance characteristics on Android?

[Monu Tripathi]

Recently, I heard about Sencha Touch and Wink are they any good? Does your book provide a listing and comparison of different options?

[Sebastien Blanc]

Yes there is a whole chapter comparing the differebt javascript/css frameworks so that you can make your choice.

Hey Guys,

As Seb pointed out, we have a whole chapter (11) that covers a comparison of four different mobile frameworks that I have personally got a bit of experience with:

Jo

jQuery Mobile

jQTouch

Sencha Touch

I haven't yet had a chance to play with Wink, but I will definitely have a look as soon as I can.

In terms of performance, we aren't really pushing the frameworks that hard, but generally it comes down to the lighter the better. Now if you are after UI frameworks then Jo is the lightest and has no external dependencies (e.g. jQuery). In general though I haven't found using jQuery to be a problem, and both jQTouch and jQuery Mobile work really well. While Sencha Touch does not have any external dependencies is probably one of the heavier weight libraries, though it's performance (once loaded, and remember you can use cache manifests to make this a once only affair) is fine. Additionally, Sencha is (in my opinion) one of the most robust frameworks when it comes to having a mobile web app display consistently across a variety of different device platforms.

Cheers,
Damon.
