Client-side template engines with automatic data-bindings. Alternatively, AJAX frameworks use JSON and then interpret the returned objects as code. Take a look at the client/server traffic produced by ZK, for instance. > As Jonathan said, the server is already generating dynamic HTML... why > have it return It isn't. There is no already generating anything server, it's a new app Nate is writing. (Unless you count his work of the past two days). The dynamic HTML he's generating is heavily tailored to his JS. There's extremely tight coupling, which now exists across multiple files written in multiple languages. Simply avoidable bad software engineering. That's not even making the computational cost argument that avoiding template processing on the server is cheaper. And with respect to Jonathan's argument of degradation, a degraded version of his app (presumably) would use <table> - or something like that, it'd look nothing like what's he showed us yesterday. Heh - the proof of the pudding is in the eating. Why don't we create 2 versions of Nate's app, one with mixed server/client - like the one he's completing now, and I create the client-side based one, and then we compare side by side? I'll work with Nate on that. - Godmar [ I hope it's ok to snip off the rest of the email trail in my reply. ]
