Yeoman MarionetteJS + Drupal generator

This generator create a HTML 5 application using a MVC pattern implemented with MarionetteJS and Backbone.Drupal for data model.

Also the HTML 5 application includes Grunt support to automate tasks and Jasmine for Unit Tests.

All Models, Collections, Views, Regions, Actions (Route + Controller) and Forms as generated as RequireJS modules encapsulated enabling the option to reuse each concepts in different areas of your application.

Compass is used to generate CSS using bootstrap-sass.

Drupal Configuration

The step zero is configure and prepare your Drupal installation to accept request specially if you are planning to execute your HTML5 application in another domain, all details about how to do this could be check in page project of Backbone Drupal

Getting Started

Install Dependencies

In order to use the Marionette Drupal generator is required install Yeoman, Bower and Grunt running the following command:

$ npm install -g yo grunt-cli bower

Install Marionette Drupal generator

$ npm install -g generator-marionette-drupal

Create a Marionette Drupal project

Finally, initiate the generator in a empty folder

$ yo marionette-drupal

yeoman generator

The Yeoman wizzard enable you define settipgs of your HTML5 + CSS3 Backbone/MarionneteJS application.

Execute sample application

The generator create a simple sample application using an empty model, simple view and render inside a content region.

Your new project has integration with Grunt and more specifically with connect and livereload and watch. So to open your new project just execute grunt using one of the following commands.

$ grunt

$ grunt watch

This command above will open your application in the following URL http://localhost:9001 and you will see a similar result as shown in following image.

MarionetteJS sample application

No webserver is requiered.

The objetive of this sample application is just demostrate the environment is ready to work and you can use the Scaffolding commands to build your application.

Scaffolding

Generate a template

$ yo marionette-drupal:template

The command above will create an empty template inside application folder app_folder/templates_folder using Twig.js

This command is interactive as you can see in the follwing image

Template Generation

Generate a Model

$ yo marionette-drupal:model

The command above start an interactive interface to provide a Model Name and if a Jasmime Test unit must be created for new Model.

In the following image you see how the command looks

Model Generation

If you choose None you can define a custom end point for your model

Generate a Collection

$ yo marionette-drupal:collection

The command above start an interactive interface to provide a Collection Name, select Model to be used in collection items and if a Jasmime Test unit must be created for new Model.

Right now you must to set the end point URL relative to Drupal Backend Server.

In the following image you see how the command looks like.

Collection Generation

Also in this sub generator is possible create a collection extending from other collection like students extending from people.

Generate a View

$ yo marionette-drupal:view

The command above start an interactive interface to provide a View Name to create a Marionette ItemViewand defining what Model or Collection will be integrate with the new view, also a what Template will be associated with view ( a new template could be generated or choose one from templates available)

Optionally Jasmime Test unit could be created for new Model.

In the following image you see how the command looks

Model Generation

Internally the generator store the MVC relation between view and model/collection to be used in Action Subgenerator.

Add a Region

$ yo marionette-drupal:region

Regions are HTML containers where views are render, an you can create as many regions your design require.

Each region match with and HTML element where the view is render inside.

Add Region

After add a region you must to add inside your HTML app file to match with ID, let me show an example.

<div id="sidebar"></div>

In our App example is located in web/index.html, remember web could change if you choose a different location for App.

Generate an Action

This generator took some terms from Symfony Application where they have the concepts of Routing, Class Controller and Actions methods. These terms match with Backnone routing and controller and actions are functions in controller associated to routes.

Instead of create three commands, I decided to combine in a single command named Action

This command enable you to add dynamically a new Route to your application and associate to a Controller function to response to the routing.

Also the system avoid to create an inline function in controller, a new RequireJS module Action is generated and is invoked inside the controller.

The saparation in Controller enable a complete isolate logic between actions.

Besides the route and controller, the action require a view to be render inside the region specified.

In the following image you see how the command looks

Action Generator

The action will provide code to fetch the information for model/collection, is your reposability to chage the proper ID as you can see in following example.

var best_exchange  = new BestExchangeCollection({});

// Load Collection
best_exchange.fetch({
success: function (Collection) {
  var best_exchanges = new BestExchangesView({collection: Collection});
  region.show();
}
});

Generate a Form

$ yo marionette-drupal:form

Only available for Drupal 8

This command generate forms implementing library Backform.

This generator enable integration with Drupal to fetch information about entities to create an HTML 5 Form to enable end users push information to Drupal Server.

This generator fetch entity information and create form matching entity fields and linked with proper REST Post to save information.

In the following image you see how the command looks

Form Generator

This subgenerator is still in progress, and the process to push back info to Drupal 8 is in progress, we will use the REST Method PATCH becuase PUT won't be implemented in Drupal 8.

Drupal 8 Setup to Enable Form Generator

In order to use this command the Drupal 8 Module Entity REST extra must be installed and enabled in your Drupal 8 Backed Server.

After enable the module you have enable Rest Resources entity/{entity}/{bundle}/fields and entity/{entity}/bundles.

Drupal 8 will not support CORS until 8.1 release, for that reason if you are need your Marionette JS App runs in a different domain apply the patch https://www.drupal.org/node/1869548#comment-9120317 recommended by Backbone.Drupal

Remember enable mod_headers if you are using Apache.

Be sure the user you provide to connect to server have permissions to fetch extra information.

Update settings

This generator store some information in a hidden file .yo-rc.json about where must be located templates, models, views etc and Drupal conection.

If you need change one of this information there is a sub generator to allow you to that to avoid edit that sensitive file, just use the following command.

$ yo marionette-drupal:settings

In the following image you see how the command looks

Update Settings

I use Inquirer to create the interactive menu, but even the documentation say you can navigate with keyword arrows doen't work, I have a reported issue. So use the numbers to navigate

Integration with Jasmine

This generator enable the option to create simple unit test against model and views, this generation is optional in sub generators model and view.

The idea is you can continue improving the unit test generated to meet the requirements of your application.

To access the unit tesst access the URL http://localhost:9001/test/ remember the Unit Test test folder is configurable via initial generator, but could updated via sub generator settings

Check how Unit Test page looks

Unit Test

You must select what entity you want create a form between Nodes and Comments, after that the generator create a list of Bundles available and after select the bundle the view modes for the bundle selected.

The form is generated using the fields present in bundle view mode.

If you update your content type bundle in Drupal 8 maybe you wanna re run the form generator.

Integration with Grunt

This generator provide a initial Grunt file to execute minimal tasks, you can run all tasks available with following command.

$ grunt

If you prefer you can execute any specific command among listed below.

Concat

$ grunt contact

Enable concat all JS files.

Todo: Configure the proper JS files and enable CSS files

Uglify

$ grunt uglify

Minify JS file combined in Contact tasks.

Todo: Configure minify for CSS files.

Imagemin

$ grunt imagemin

Optimize images in your project.

Compass

$ grunt compass

Enable process SASS files to generate CSS files in your project. This project include bootstrap-sass

Watch

$ grunt watch

Monitor when SASS files are modified to generate new CSS files.

ToDo

  • Implemente PATCH method in forms submit against Drupal 8
  • Update form sub generator to review image fields
  • Update documentation about list of commands implemented in grunt
  • Create RoadMap
  • Update Forms project to enable image fields
  • Create Layout Scaffolding command
