Connecting Backbone.js to Kinvey

// We use a separate function rather than defining this
// twice: once for the Model, and once for the Collection
kinveyAuthenticatedSync = (method, model, options) ->

  // Before we send the request ...
  options.beforeSend = (jqXHR) ->

    // Add the Basic Authentication header
    jqXHR.setRequestHeader(
      'Authorization', 
      'Basic ' + $.base64.encode(
        kinvey_app_key + ':' + kinvey_master_secret
      )
    )

  // Now that we added the Basic Authentication header,
  // call the default Backbone sync method
  Backbone.sync.call(this, method, model, options)

// All models stored on the Kinvey backend will subclass from
// KinveyModel rather than Backbone.Model
class KinveyModel extends Backbone.Model
  sync: kinveyAuthenticatedSync
  idAttribute: '_id'

// Same for collections - they should subclass from KinveyCollection
class KinveyCollection extends Backbone.Collection
  sync: kinveyAuthenticatedSync
