Today, User experience (UX) is not just about how a user feels when interacting with your website. In this world of rapidly growing interfaces and APIs, content plays a supreme role in offering your users with exceptional UX. To keep up the pace, you need to adopt hot-selling, fast-moving front-end technologies like Angular JS, React JS, etc. that can deliver your content in an application-like speed. Headless Drupal (or decoupled Drupal) is one such approach that is gaining much popularity because of its innovative ability to deliver outstanding digital experiences. Bigwigs like Weather.com, The Tonight Show, Great Wolf Resorts, Warner Music Group and many more, have taken the headless Drupal route offering their customers with interactive and unique front-end designs and fast-loading websites.
What is Headless Drupal?
To go headless or not is a rather tricky decision to make in this digital world. So what’s the whole buzz about going Headless? Simply put, in a headless Drupal architecture, the front-end (consumers of content) of the CMS is detached from the back-end (provider of content).
Conventionally, Drupal websites are meant to multi-task. Which means, Drupal manages both - the back-end content management as well as the front-end rendering of content. There is no doubt that Drupal CMS on its own can deliver a rich user experience to the end user but when it comes down to instantaneous responses for a request, delivering content seamlessly in different interfaces, it does fall short. In a decoupled Drupal architecture, instead of the Drupal’s theme layer, a client-side framework like AngularJS, React or Backbone.JS is used. A user request does not have to be processed by the server all the time, which can drastically improve the speed and UX of your Drupal website.
Technically speaking, a headless Drupal website sends out data in JSON format instead of HTML. A powerful front-end UI framework renders this data in JSON format and delivers the web page.

Fully Decoupled Architecture
Is it a good idea?
Traditionally, Drupal CMS is meant to do both – content management and rendering the front-end for the whole website. A lot of pressure, don’t you think? Drupal experts believe that Drupal’s strengths lies in the power and flexibility of its back-end and that it needs to be service oriented first instead of HTML oriented. Decoupling Drupal means letting some other system manage the front-end while Drupal takes care of the back-end system. Why is it a good idea to decouple Drupal, you ask?
If you want to adopt cutting-edge and modern front-end technologies that Drupal cannot provide you will need a powerful front-end framework like React JS or Angular JS. With a headless Drupal approach, you can have all of this and still maintain your robust backend Drupal CMS.
- With the Headless Drupal architecture, you can “Write once and publish everywhere”. This system allows content editors, marketers and business owners to create content once and deliver it to multiple interfaces seamlessly.
- With a decoupled CMS, detaching the front-end from the back-end content management system will allow for more flexibility and efficiency of the Drupal content model. Just like how delegating work decreases your workload and increases productivity.
- A layered architecture promotes a more secure system. Site admins can restrict access to different areas of the infrastructure.
- Headless Drupal allows front-end developers to have full control over the presentation, UI design and UX of the website. The combination of a great client-side framework and a seasoned front-end developer can get you a website with a rich, faster, application-like user-experience, and seamless interactivity.
- Integrating with third party applications is easier and more efficient with a headless Drupal model.
- Both the front-end and back-end developers can work independently which can lead to efficient and speedy delivery of a project.
- If you want to redesign your website, you won’t have to re-implement your Drupal CMS. Likewise, revamping your back-end system can be accomplished without having to alter your front- end.
Is headless Drupal for everybody?
Although decoupling Drupal can help you achieve your goals of an uninterrupted and application-like user- experience, it might not be a good fit for everyone. Here’s why –
- Websites like News sites or Blogs, that don’t really need much user interactivity, will not benefit from decoupling their Drupal website.
- When you opt for a fully decoupled Drupal architecture for your website, you are letting go of some of the top (and free) functionalities that come with the Drupal theme layer like the block placements, layout and display management, content previews, UI localization, security features like cross-site scripting (XSS), etc. Some of them cannot be replicated by a client-side framework.
- If budget is an issue you need to keep in mind about the price you will have to shell out for experienced front-end developers. Also the cost for rebuilding a missing (otherwise freely available) Drupal feature from scratch.
Who uses Headless Drupal?
Many top enterprises have taken the headless Drupal approach and successfully so! Their websites are fast to load and offer interactive experiences to their users in all devices and interfaces. Some examples are –
- The Tonight Show with Jimmy Fallon – uses Backbone.js and Node.js for the front-end
- Weather[dot]com – uses Angular.js for the front-end
- Great Wolf Resorts – uses CoffeeScript and Spine framework
- EC Red Bull Salzburg – uses Angular.js for the front-end
- Warner Music Group – uses Angular.js for the front-end
