AJAX Design Patterns
An interesting link I found on del.icio.us– AJAX Patterns: Design Patterns for AJAX Usability.
Patterns are just a concise way to represent the knowledge embodied in the many AJAX applications that are out there. The point is to discover best practices by investigating how developers have successfully traded off conflicting design principles. AJAX is all about usability, so the patterns focus particularly on delivering usability in the face of constraints, most notably: user capabilities and expectations, bandwidth limits, the stateless nature of HTTP, the complexity of Javascript.
I haven’t used AJAX for anything at all thus far, but it’s something I’m keeping my eye on.
