Example of using Coffeescript classes and RequireJS (or Curljs or similar) for client side browser library

Question

We want to develop a browser (client side only) library using Coffeescript, and in particular, we tend to use the \"class\" capability of Coffeescript quite a bit, in addition t

First off, if you're using RequireJS you're going to have a not-easy time returning multiple "things" from a define function. RequireJS uses AMD (!NOT! CommonJS) format "standards", which doesn't contain a module.exports object for exporting "stuff" but instead relies on return something.

With that said, I'm not exactly sure what you're looking for here but having a class work with RequireJS is pretty easy. Something like this:

define ['my/required/module'], (myModule) ->
    class MyOtherModule
        privateField = 0

        constructor: ->
        publicMethod: ->

    return MyOtherModule

This can be used in a require/define function just like any other script. Take this example:

require ['my/other/module'], (MyOtherModule) ->
    instance = new MyOtherModule()

We can even use it with "extends"

define ['my/other/module'], (MyOtherModule) ->
    class MyThirdModule extends MyOtherModule
        ...   

Hopefully this helps!
