ClassesProbably the most highly-linked article is Alexander Hill's CoffeeScript and AngularJS (July 2013). Alex gives the usual compelling arguments for CoffeeScript readability, and also shows an example of an AngularJS service that uses CoffeeScript classes instead of directly modifying a function's prototype. Rocky Jaiswal's short post Angular.js Hacks (May 2013) provides additional examples of using CoffeeScript classes for controllers, services, and directives. The Post 4 Lessons Learned Doing Angular On Rails contains a section on "Angular models as Coffeescript classes" that is unrelated to Rails (the post also has good info on Rails and AngularJS).
YeomanOf course, if you want the latest and greatest Gruntfile for your AngularJS project, you should probably generate it with Yeoman.
Unfortunately, Yeoman Testing With Coffeescript is just a short post that should probably be retitled, since it's just focused on an issue related to Karma configuration.
