The CARB stack: Coffee + Angular + Rails + Bower

AngularJS is a great way to build modern web apps and this affects Rails programmers. The combination of both is an excellent choice: Build your single-page app in Angular and let it communicate via JSON with your Rails-API backend (btw, this is exactly what we did for palava).
