Question

Is there any intrinsic support for namespacing in coffeescript?

Adequate namespacing seems like something coffeescript could really help with although I don’t seem to be able to find anything to suggest that there is support for this.

A way to make it simple to reference the class both in it’s own “namespace” (the closed function) and the global namespace is to assign it immediately. Example:

# Define namespace unless it already exists
window.Test or= {}

# Create a class in the namespace and locally
window.Test.MyClass = class MyClass
  constructor: (@a) ->

# Alerts 3
alert new Test.MyClass(1).a + new MyClass(2).a

As you see, now you can refer to it as MyClass within the file, but if you need it outside it’s available as Test.MyClass. If you only want it in the Test namespace you can simplify it even more:

window.Test or= {}

# Create only in the namespace
class window.Test.MyClass
  constructor: (@a) ->
