I did a similar simple Todos application using Backbone.js + CouchDB:<p><a href="https://github.com/edc/backbone-sample" rel="nofollow">https://github.com/edc/backbone-sample</a><p>It's about 80 lines of CoffeeScript and 0 lines of server side code.<p>CouchDB's RESTful API makes it a really natural choice for storage backend for Backbone-powered applications.
Thanks for the demo and source. I am trying out Backbone and GAE too. What I wonder about and asked on StackOverflow but didn't get a clear answer is how to join together Backbone on the client side and ProtoRPC on the server side. Do you have any ideas? Thanks.
