Backbone.Drupal is a standalone plugin to connect Marionette JS and Backbone JS applications with Drupal 7

Inspired in JS files from Drupal Module https://drupal.org/project/backbone

Download

$ git clone https://github.com/enzolutions/backbone.drupal

Features

Cross-origin: Enable to have Drupal as Backend in a Domain backend.com and the Backbone/Marionette App in other domain frontend.com.

In your Drupal Server you must setup HTTP Access Control to enable connection, below and example.

Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:X-CSRF-Token
Access-Control-Allow-Methods:POST,ADD,GET,PUT,DELETE,OPTIONS
Access-Control-Allow-Origin:http://localhost:8080

You must change the origin to use the domain you are using to run your application.

I strong recommend to use the Drupal module CORS to configure the HTTP Access Control

Authentication: Option login with Drupal user account to enable to execute REST operation PUT, DELETE, ADD. If Cross-origin is enabled login is required for GET operations.

Models: Created Backbone models for Nodes, Users, Comments Entities

You can add extra fields to modules to use as extra information in you application, these extra fields could be mark as noSaveAttributes. Check the following example.

var Property = Backbone.Drupal.Models.Node.extend({
      initialize : function(options) {
        // Setting the Id Attribute for Drupal model
        this.attributes.nid = options.property_id;
        this.noSaveAttributes = ['property_id'];

        // Extended Backbone.Drupal.Models.Node to my own service for Drupal Nodes.
        // This Rest service return absolute URL for field pictures
        this.urlSource = "node_waterbed";
       },

Collections: Created Backbone collection for Users, Nodes and Views

REST: Integration with Services Server type REST

ToDo

  • Implement Collections for Taxonomies and Search
  • Create integration with module Restws
  • Create version of plugin for Drupal 8.
