Michael Mahemoff’s Ajax Patterns Wiki is more than just about patterns. There’s a bunch of information on frameworks, tutorials and examples. But if you have a taste for design issues and general, repeatable solutions for solving them as they apply to Ajax (i.e. a design pattern), then this resource is for you.
Patterns are divided into several categories: Foundation Technology, Programming, Functionality and Usability. There are 62 patterns in all, along with some development tips and practices (testing, logging, etc.). Some of the patterns are empty for now, such as the "Multithreading – Use a timer and a worker queue to process jobs without the blocking application flow" pattern.
Some of the patterns are a little light on detail and might be termed more "good ideas when implementing Ajax apps," but they are nonetheless useful. The "real life examples" sections are particularly valuable.
