I wrote a while ago about creating a client side MVC system in javascript.
Yesterday at one of the talks SproutCore was mentioned. I had a look today and it looks very promising. It’s a full framework designed to create full ‘thick client’ javascript applications. The core of it was written in Ruby and I haven’t looked into whether you have to know much Ruby to develop in it or not. It reminds me of symfony because you are given a number of build tools to use on the command line for creating controllers, new projects, models etc etc.
I think I’m falling in love with the general idea and it’s great to see someone has actually implemented it quite well (from the looks of it). I haven’t had the chance to try it out yet but I’m thinking of using it on a number of personal projects so we’ll see how it goes!
