As I've written previously, the Waterwheel ecosystem and Reservoir distribution help pave the way for non-Drupal developers to use decoupled Drupal as a headless back end without having to learn a lick of Drupal or PHP. Thanks to the Contenta team, there is now a growing slate of applications backed by decoupled Drupal and web services modules like JSON API and Simple OAuth.
In this blog post, I'll highlight each of these projects and how you can get started with them to accelerate your development process.
ember-drupal-waterwheel: An add-on for Ember developers
Created by Acquia Labs developer Chris Hamper, the
ember-drupal-waterwheel add-on (GitHub) provides crucial blueprints to help you rapidly develop a Drupal-backed Ember application. Not only is the add-on compatible with Ember's FastBoot add-on for server-side rendering; it supersedes with minimal overhead many of the techniques I outlined in my "Decoupled Drupal and Ember" blog series.
ember-drupal-waterwheel add-on is intended for use when creating a new Ember application or when connecting an already in-progress Ember application to an API-first Drupal site, whether homegrown or built in Contenta or Reservoir. Though Ember comes with a generic
JSONAPIAdapter, this add-on's built-in adapter and serializer handle Drupal-specific JSON API requests and responses natively. Also,
ember-drupal-waterwheel allows you to integrate OAuth2 authentication into your application.
Possibly the most compelling feature of the
ember-drupal-waterwheel add-on is the ability to generate Ember models, routes, templates on the fly which correspond to Drupal entity types simply by using the
ember generate command with arguments prefixed with
ember g drupal-article,
ember g drupal-tag). The resulting files can be hand-modified to produce the desired appearance and behavior. Generating the necessary models, routes, and templates for custom Drupal entities is also simple (
ember g drupal-entity your_entity_name).
To get started, use Ember CLI to install the add-on and start generating!
$ ember new my-app
$ ember install ember-drupal-waterwheel
$ ember generate drupal-article
ember-waterwheel-app: A reference app for Ember–Drupal integration
A screenshot of
ember-waterwheel-app, another project by Acquia Labs developer Chris Hamper, is a Drupal-backed reference application in Ember. When connected to a Drupal back end, it provides a list of available content entities such as nodes, users, and taxonomy terms and basic CRUD (create, read, update, delete) capabilities for nodes of type Article.
This reference application demonstrates some additional features available beyond the
ember-drupal-waterwheel add-on, including widgets for editing formatted text fields (like the Body field) and taxonomy terms. By simply connecting Reservoir, Contenta, or an API-first Drupal site to this full-fledged Ember front end, you can jump-start further development by extending the existing functionality or styling the application to suit your needs.
Creating a new article using
ember-waterwheel-app's editorial interface.
Clone the repository and install dependences, then hook up your Drupal site.
$ git clone https://github.com/acquia/ember-waterwheel-app
$ cd ember-waterwheel-app
$ npm install
$ bower install
react-waterwheel-app: A reference app for React–Drupal integration
A user's page on
react-waterwheel-app which shows a listing of content associated with that user.
Developed by Matt Grill,
react-waterwheel-app uses the Waterwheel.js library in a reference React application which demonstrates an integration with a Drupal back end. The application includes a rudimentary editorial interface for CRUD against content entities, much like the aforementioned Ember reference application.
Leveraging a simple configuration file (
src/config.js) within the application, you can rapidly connect this React application to a Drupal back end by providing the Drupal host name and OAuth2 information.
To get started with
react-waterwheel-app backed by a pre-existing Drupal site, simply clone the repository and run:
$ git clone https://github.com/acquia/react-waterwheel-app
$ cd react-waterwheel-app
$ yarn install
While the Waterwheel ecosystem continues to grow, with compelling new implementations to add to the applications already in progress by the Contenta team, we can't motivate how to build upon our work or what to build next without your input, feedback, and bug reports. Give these three projects a try against a vanilla API-first Drupal site, Reservoir, or Contenta, and let us know what you think — or even better, file a pull request on GitHub!
