Run CoffeeScript class in browser and in node

Question

I have a class in CoffeeScript that I would like to use both on the server and in the broser.

For the server I need

class classname
    constructor: (@arg)->
        #code

module.classname = classname

But for the brwoser I need

class classname
    constructor: (@arg)->
        #code

window.classname = classname

Is there anyway to make it so that only one file has to be maintained?

Answer 1

In the general case it requires using libraries like requirejs and browserify, but in your case you can simply write:

class classname
  constructor: (@arg)->
    #code

module?.classname = classname
window?.classname = classname

This code will check the existence of module and window variables before modifying them.
