This isn't a full-blown example, but AngularJS works phenomenally as an interaction layer on top of a REST API. Creating such an API with Rails is almost trivial. Postgres + Rails + AngularJS (via Bower) has become my go-to stack and is an absolute blast to develop with.

I'm pretty much doing the exact same thing, but with django instead of rails. That gives a very nice Postgres + Django + AngularJS. When I need to add realtime feeds I throw RabbitMQ with the Web-Stomp Plugin into the mix: it works amazingly well!

This is the approach I'm taking for the Admin, actually. Haven't started yet, but really looking forward to it.

Nice. If you're not already familiar with Restangular, be sure to check it out: https://github.com/mgonto/restangular

I tried rolling my own Angular API service, and it was a great learning experience, but Restangular trumps any vanilla service I could roll.

Do you have a link for a guide or tutorial to doing this?
