"How do I build larger applications using jQuery?" It's a question that starts to creep into the minds of virtually every jQuery developer after building one or two non-trivial web applications. There are many good answers to this question, and even some talks at this conference that describe ways to use code organization and other techniques to help scale applications.
Perhaps he most important structural issue--one that virtually every one of these solutions tackles in one way or another--is the fact that many jQuery applications use the DOM to store facts instead of simply visual display. This means that changing visual display often has all sorts of implicit dependencies on other parts of the page, and not clean structural way to describe these dependencies.
In this talk, Yehuda will talk about how this problem manifests itself in real applications, and what techniques you can use to mitigate the problem. He learned many of these techniques by working on SproutCore, so he will use SproutCore's system as a reference where appropriate.

You thought you were building a proof of concept, but then that proof of concept went live. Or you had two weeks to build what should have taken two months. Or the handful of progressive enhancements you threw onto a page to make the user experience a little nicer somehow evolved into an entire single-page app. Whatever the reason, you find yourself with a full-blown application built around click events and a staggering number of plugins you can't even remember downloading. If you could rewrite it, you'd use a framework built with your scenario in mind, but it gets 17 zillion hits a day and there's only one of you and starting from scratch isn't an option. No, what you need is the philosophy of a framework broken into discrete pieces that fit into a one- or two-week release cycle. This talk aims to provide bite-sized strategies you can implement in a short amount of time with minimal disruption to unchain your application from the DOM.
