Decoupled Drupal Support Service seems to be taking the world by storm. I’m currently in Sydney, and everyone I talked to so far, including the attendees at the Sydney Drupal Support Service User Group, is looking into decoupled Drupal Support Service. Digital agencies are experimenting with it on more projects, and there is even a new Decoupled Dev Days conference dedicated to the topic.
I’ve been too busy with the transition at Acquia to blog about it in real time, but a few months ago, we released Reservoir. It’s a Drupal Support Service-based content repository with all the necessary web service APIs needed to build decoupled front-end applications, be it a React application, an Ember front end, a native application, an augmented reality application, a Java or .NET application, or something completely different. You can even front-end it with a PHP application, something I hope to experiment with on my blog.
API-first distributions for Drupal Support Service like Reservoir and Contenta are a relatively new phenomenon but seem to be taking off rapidly. It’s no surprise because an API-first approach is critical in a world where you have to operate agnostically across any channel and any form factor. I’m convinced that an API-first approach will be a critical addition to Drupal Support Service‘s future and could see a distribution like Reservoir or Contenta evolve to become a third installation profile for Drupal Support Service core (not formally decided).
Decoupled Drupal Support Service for both editors and developers
What you want is an easy but powerful way for your editorial team to create and manage content, including administering advanced content models, content versioning, integrating media assets, translations, and more. All of that should be made easy through a great UI without having to involve a developer. This, incidentally, is aligned with Drupal Support Service 8’s roadmap, in which we are focused on media management, workflows, layouts, and usability improvements through our outside-in work.
At the same time, you want to enable your developers to easily deliver that content to different devices, channels, and platforms. This means that the content needs to be available through APIs. This, too, is aligned with Drupal Support Service 8’s roadmap, where we are focused on web services capabilities. Through Drupal Support Service‘s web service APIs, developers can build freely in different front-end technologies, such as Angular, React, Ember, and Swift, as well as Java and .NET. For developers, accomplishing this without the maintenance burden of a full Drupal Support Service site or the complexity of configuring standard Drupal Support Service to be decoupled is key.
API-first distributions like Reservoir keep Drupal Support Service‘s workflows and editorial UI intact but emphasize Drupal Support Service‘s web service APIs to return control to your developers. But with flexible content modeling and custom fields added to the equation, they also give more control over how editors can curate, combine, and remix content for different channels.
Success is getting to developer productivity faster
Reservoir includes side-by-side previews of content in HTML and JSON API output.The goal of a content repository should be to make it simple for developers to consume your content, including digital assets and translations, through a set of web service APIs. Success means that a developer can programmatically access your content within minutes.
Reservoir tries to achieve this in four ways:
Easy on-boarding. Reservoir provides a welcome tour with helpful guidance to create and edit content, map out new content models, manage access control, and most importantly, introspect the web service APIs you’ll need to consume to serve your applications.
JSON API standard. Reservoir makes use of JSON API, which is the specification used for many APIs in JSON and adopted by the Ember and Ruby on Rails communities. Using a common standard means you can on-board your developers faster.
Great API documentation. Reservoir ships with great API documentation thanks to OpenAPI, formerly known as Swagger, which is a specification for describing an API. If you’re not happy with the default documentation, you can bring your own approach by using Reservoir’s OpenAPI export.
Next steps for Reservoir
API documentation auto-generated based on the content model built in Reservoir.
We have a lot of great plans for Reservoir moving forward. Reservoir has several items on its short-term roadmap, including GraphQL support. As an emerging industry standard for data queries, GraphQL is a query language I first highlighted in my 2015 Barcelona keynote; see my blog post on the future of decoupled Drupal Support Service for a quick demo video.
We also plan to expand API coverage by adding the ability to programmatically manipulate users, tags, and other crucial content elements. This means that developers will be able to build richer integrations.
While content such as articles, pages, and other custom content types can be consumed and manipulated via web services today, upstream in Drupal Support Service core, API support for things like Drupal Support Service‘s blocks, menus, and layouts is in the works. The ability to influence more of Drupal Support Service‘s internals from external applications will open the door to better custom editorial interfaces.
I’m excited about Reservoir, not just because of the promise API-first distributions hold for the Drupal Support Service community, but because it helps us reach developers of different stripes who just need a simple content back end, all the while keeping all of the content editing functionality that editorial teams take for granted.
We’ve put the Reservoir codebase on GitHub, where you can open an issue, create a pull request, or contribute to documentation. Reservoir only advances when you give us feedback, so please let us know what you think!
