Tracking Backbone errors with track:js, ported to CoffeeScript

backbone-trackjs.coffee

# OPTION 1:
# Automatically wrap everything

do ->
  'use strict'

  return unless window.trackJs?

  for klass in ['View', 'Model', 'Collection', 'Router']
    old = Backbone[klass]
    class Backbone[klass] extends old
      constructor: ->
        @_trackJs = true unless @_trackJs?
        trackJs.watchAll(this, 'model', 'constructor') if @_trackJs # additional parameters are excludes. Collection.model does not support watching.
        super

# OPTION 2:
# Selectively wrap objects on instantiation.

class MyView extends Backbone.View
  initialize: ->
    window.trackJs?.watchAll(this, 'excludedFunction')
