Having trouble integrating Backbone-relational with AMD (RequireJS)?

I'm struggling with my Backbone router and module definitions in CoffeeScript. Can someone help me troubleshoot?

// appointments_router.js.coffee
define ["app", "appointment"], (App) ->
  class Snip.Routers.AppointmentsRouter extends Backbone.Router
    initialize: (options) ->
      @appointments = new Snip.Collections.AppointmentsCollection()
      @appointments.reset options.appointments

Here is the "appointment" module code:

// appointment.js.coffee
define ["app", "relational"], (App) ->
  class Snip.Models.Appointment extends Backbone.RelationalModel
    paramRoot: "appointment"

    defaults:
      time_block_type_code: "APPOINTMENT"
      start_time: null
      start_time_time: null
      start_time_ymd: null
      stylist: {}
      client: {}
      notes: ''

Lastly, check out my application.js.coffee:

require
  paths:
    underscore: "lodash.min"
    appointment: "backbone/models/appointment"
    appointmentsRouter: "backbone/routers/appointments_router"
    relational: "backbone-relational"
  shim:
    "underscore":
      exports: "_"
    "backbone":
      deps: ["underscore"]
      exports: "Backbone"
    "relational":
      deps: ["backbone"]

requirejs ["appointmentsRouter"], (AppointmentsRouter) ->
  window.router = new Snip.Routers.AppointmentsRouter({appointments: []})
  Backbone.history.start()

Encountering errors on page load such as

Uncaught TypeError: undefined is not a function
or
Uncaught TypeError: Cannot set property 'Relational' of undefined
? Let's figure out how to resolve these issues.

Answer №1

To enhance compatibility, consider implementing a shim configuration along with Require.js instead of relying on AMD like Backbone does.

Visit https://github.com/DarrenHurst/BroadStreet

to see an example of how to set up a shim configuration.

Answer №2

It appears that jQuery is a necessary requirement.

  configuration:
    "lodash":
      exports: "_"
    "backbone":
      dependencies: ["lodash", "jquery"]
      exports: "Backbone"
    "relational":
      dependencies: ["backbone"]
