Export a class from a Coffeescript file
Your code will indeed make userModel a global, assuming that exports is undefined and this is window. If you're having problems, check those conditions.
The class ... form is an expression that returns a value. So, you'll want to assign the result of that class expression to a property on your export object. Like so:
root.userModel = class userModel username: 'Aaaa' name: 'Bbbb'Update:
Oops, not true, should work fine either as class root.userModel or as root.userModel = class userModel.
just define your class with a '@' before its name
class @ClassName blablabla: -> blablalblablabla
