Minimalist cacheable jQueryjavascript library for iPhone? - Stack Overflow

Given the iPhone's 25k limit for caching of files, I'm wondering if there's interest in an iPhone optimized javascript library that makes caching a top level goal. Since it'd be iPhone only it could get rid of most cross-browser cruft and rely on safari specific capabilities, hopefully cutting down some of the girth and staying with 25k.

John Resig discusses this briefly, although mostly to dismiss it, it seems. He does mention:

if you're particularly excited about breaking jQuery down into little chunks you can grab the individual pieces from SVN and build a custom copy.

Anyone tried that?

Dojo implements a 6k version that seems to rely on deferred loading. I'm mostly a jQuery user so I haven't given it a try, but it looks interesting.

Overall: what do you think about a safari/iphone specific javascript library that implements, say, the top 90% most used APIs in jQuery (or your other favorite library)?

• It would be interesting to have a stripped down version that just provides the DOM traversal parts, since that is what jQuery is so effective with. Event handling would also be a MUST in my opinion. – Dan Herbert Commented Nov 25, 2008 at 3:55
• Dojo also has a Webkit-only build with conditional pilation, so you can choose the modules you want without the IE/Moz branches, and choose to roll them up or load the modules on demand. Does the 25k unzipped limit still apply? I was under the impression that changed a while ago with a Safari update. – peller Commented Dec 23, 2009 at 15:38

Newer update: looks like Zepto is the way to go these days.

Found XUI, looks like what I was looking for, although I haven't given it a try yet.

You should check out QuickConnectiPhone. It may do what you want. It can be found at https://sourceforge/projects/quickconnect/. It also lets you write your app in JavaScript, CSS, and HTML and yet install it on a device.

There is an API that will allow you to make calls down to the Objective-C layer as well for phone vibration, GPS locations, accelerometer information, and some more. You can even extend this to other native phone behaviors as well.

The development blog for the framework is found at http://tetontech.wordpress.

I'm experimenting with XUI as well, looks promising, seems to follow JQuery-way of doing things.

The same people also created 'lawnchair' for persistant storage of data in json format, XUI+lawnchair looks like a great bination for cross-platform (as in at least iphone+android, maybe webos, symbian, blackberry and ms as well) mobile development.

I think it would be fantastic, but it would be hard to match the testing and reliability of jquery unless someone really picks it up and runs with it. If there was a lightweight, safari only version of jquery that was pletely patible with the plugins and documented methods, it would be a godsend.

Given the increasing popularity of the iphone, I think it would be a really useful thing, it might be possible to remove the cross browser stuff and get it down to size.... however, it would be even more useful if the iphone had a more realistic cache limit.

It does make me wonder if the cache limit in the iphone was determined by the capacity of the hardware or the business needs of the carriers. A 50K cache limit would reduce a lot more carrier usage...
