Silently updating Ember-app on client side

silent-updater.coffee

`import 'ember'`

# this is an first raw attemp on "silent ember app updates"
# more info -- http://discuss.emberjs.com/t/best-practices-for-updating-ember-app-on-client/6502

versionMonitor = Em.Object.create
  current_version: null
  availabe_version: null
  
  ###
    trick is to update availabe_version somehow (websokets/long-poll ...)
  ###

  is_update_needed: (->
    if @get('current_version.hash')
      if @get('current_version.hash') != @get('availabe_version.hash')
        return true
  ).property('current_version', 'availabe_version')


Ember.Application.initializer
  after: "store"
  name: 'silent-updater'
  initialize: (container, application) ->
    versionMonitor
    # set current version
    versionMonitor.set 'versionMonitor', {hash: 'XXX'} 
    
    # listening for router transitions
    application.Router.reopen
      willTransition: (->
        if versionMonitor.get('is_update_needed')
          window.location.reload()
      ).on('didTransition')

The name seems confusing since the willTransition function is executed on didTransition not on willTransition
