Are there any design patterns for AJAX? Can you please name some of them and their purposes? Thanks!

Hi Ais,

Yes, there are plenty of them!

There are at least two kinds of design patterns in Ajax:
1. usability/workflow design patterns
2. Software design patterns

The two main bodies of literature on 'Ajax Design Patterns' are Michael Mahemoff's wiki, and subsequent book of that name by o'Reilly (, and Bill Scott's stuff at Yahoo! developer site ( Both of these talk principally about useability & workflow patterns, along with some discussions of request-response/comms patterns.

I discussed software design patterns in 'Ajax in Action' quite a bit, and more recently at a talk that I gave at QCon in London. The names here will be familiar - Observer, Model-View-Controller, Strategy, etc. - straight from the Gang of Four.

The interesting thing to me about applying design patterns in JS is that most of the literature has been on heavily OO languages - C++, Java, C# - whereas JS is muuch more aligned with functional programming. Hence, one approaches the __implementation__ of familiar patterns a bit differently.
