I've been working on something pretty similar, but on the server side. It's called 'Neurons', and it's a pre-alpha Python library. It's built on Spyne[3], an RPC framework which is another side project of mine that I've been working on for ~4 years now.

The aim with neurons initially is to let you generate a html form (e.g. [1]) and related services from just a model definition and an instance of this model (e.g. [2]), making it a breeze to publish CRUD pages. It currently handles complex stuff like dates, times, arrays and nested objects just fine.

In Spyne terms, that's "serializing a model instance using the HtmlForm protocol". The same object definition can be used to for other protocols like json as well as for persisting data to a relational database (via SQLAlchemy). You can play with the code generator at http://spyne.io to get a better feel about how it works.

One could even write a Spyne protocol that renders a given model instance to way.js code.

Help is welcome!
