Using Proxy Module instead of Globals

app.coffee

# .. Start express app
app = createExpressApp()
require('./routes') app

common.coffee

common = module.exports
common.models = require './models'
common.controllers = require './controllers'

controllers.coffee

module.exports =
  students: require './students.controller'

models.coffee

module.exports =
  Student: require './student'

routes.coffee

common = require '../common'

module.exports = (webapp) ->
  app.get '/student/:_id', ->
    common.controllers.students.view req.params._id

students.controller.coffee

common = require '../common' # this will replace using global.models and keep our dependencies clear

module.exports =
  view: ->
    # ... do stuff
    return common.models.Student.view

What.md

By using a common module (we can name it whatever we want), we make dependencies explicit, reduce unnecessary documentation, and avoid polluting the global namespace.
