Choco by Anthony Heukmes is a framework for building web apps built from one HTML page. It’s a bit like Cappuccino and SproutCore, except a lot simpler. It’s built from 3 other libraries:
- Sammy – a client-side, jQuery-based Sinatra style routing framework
- js-model – a way of handling data structures in the client
Most of Choco seems to be built by Ruby developers, and the author has a Rails 3 example project. If you’re building Rails projects you might find something useful here.
