CoffeeScript and NodeJS: How do I export multiple classes?

Question

I want to export some classes, say, Dog and Cat. One way to go about this is:

class Dog
  bark: -> console.log "Arff! :D"

class Cat
  meaow: -> console.log "Meaw!"


module.exports = {Dog, Cat}

How can I do something similar without typing the class names twice?

Answer 1

You could use something like this:

class exports.Dog
  bark: -> console.log "Arff! :D"

This compiles down to:

exports.Dog = (function() {

  function Dog() {}

  Dog.prototype.bark = function() {
    return console.log("Arff! :D");
  };

  return Dog;

})();

Answer 2

An alternative way to this is by doing the following:

module.exports = 
   Dog: class Dog
          bark: -> console.log "Arff! :D"

   Cat: class Cat
         meaow: -> console.log "Meaw!"

Then you can do the following:

animals = require './animals'

dog = new Animals.dog()
