The online version[1] was submitted 10 days ago[2] (by someone else) but it didn't get any attention. So I submitted a link to the epub version. It seems like a very good tutorial and I hope someone finds it useful.
Also, I'm watching a terrific presentation from the book's author right now:
Large-scale JavaScript Application Architecture
Developers creating JavaScript applications these days usually use a combination of MVC, modules, widgets and plugins for their architecture. They also use a DOM manipulation library like jQuery.
Whilst this works great for apps that are built at a smaller-scale, what happens when your project really starts to grow?
In this talk, I present an effective set of design patterns for large-scale JavaScript (and jQuery) application architecture that have previously been used at both AOL and Yahoo amongst others.
You'll learn how to keep your application logic truly decoupled, build modules that can exist on their own or be dropped into other projects and future-proof your code in case you need to switch to a different DOM library in the future.
