Christian Snyke who earlier published AJAX Design Patterns article, has just published a must read tutorial for all Ajax lovers, who want to design the application using Prototype and script.aculo.us as base.
He explains the need of the tutorial "The internet is full of tutorials explaining those little tricks about AJAX, how to handle XHRequests and all that low level stuff, but nobody tells you how to design the entire application, nobody gives you the overview on how all these things should work together. What good is knowing all those fragments if the developer is unable to put them together to a real use? We have libraries to abstract from the Browser dependant things like actually doing XMLHTTPRequests, and we should concentrate on higher level design to give our clients (or visitors) good and usefull applications.
This is why in this tutorial I’ll try to give you an idea on how the actual design works. I’ll be heavily relying on my last tutorial for the layout of the final application, but we’ll go much more into detail about the decisions we take. Some parts may be applicable to non-Web-2.0 Web design and some even come in handy when designing completely non-web related applications."
Overall he tries to cover the all aspects of application step by step, starting from Requirement gathering to Implementation.
Check out the working copy of the application.
