![]() Usually you will keep the header and footer so that the page looks part of the same site. First you create this page callback in hook_menu(), then create an which has all the regions that you need on the page. As an example, you want to implement the headless Drupal technique on the page /ui. To avoid this, you can let Drupal respond with the base HTML with the same JS and let the JS call Drupal's API on page load. If Drupal is completely decoupled from the front-end for some pages, then on those pages, you will need to make the same theme/template on front-end HTML file as the one Drupal has. Irrespective of the page you are on, you want the site layout and template to look similar. On the other hand if your HTML file is on the same domain as Drupal's, then you are essentially doing theming twice. If your HTML file is on a different domain than Drupal's, JS will first need to make a back-end call to log in and then make a second call to get the data. For authenticated users, it gets slightly more complicated. The above scenario will work very well if data that the HTML file is requesting is available to anonymous users. So you can replace Drupal with any other technology in future, or Drupal 8 for that matter, without making any change to the front-end as long as the APIs remain the same.Ģ) Drupal renders the HTML page in the above example. Advantage of this approach is that the back-end is totally decoupled from front-end. ![]() Now JS in the HTML file parses the received JSON and renders it to create the full HTML page. Instead of responding with HTML, it returns JSON back to the HTML file. On the back-end, Drupal uses Services or RestWS module to respond to the request received from the HTML file. node id) to the back-end in the API call. Usually, you will parse the URL and pass in the id (for e.g. When this HTML page loads, JS executes a back-end API call to get the data. Here's a very simple example: in the front-end, you have a plain HTML file with some JS. It only cares about the APIs that the back-end is exposing. In this case, front-end UI doesn't really care what the back-end technology is. Here are two ways that are popular:ġ) Drupal is totally de-coupled from front-end UI. That said, there are multiple ways you can implement this, depending on how integrated your UI is with Drupal. ![]() You can use a new JS front-end framework backed by Drupal's reliability and flexibility in the back-end. With headless Drupal, you get the best of both worlds. A front-end UI framework, such as AngularJS, EmberJS or React, renders the data to create a webpage.Īs you must be aware, recently there has been an explosion of front-end JS frameworks and Drupal's UI has not been able to catch up with it.Instead of spitting out HTML, Drupal spits out data in JSON format. ![]() It involves two changes from standard Drupal: How is it different than standard Drupal and how can you implement it? If these are the questions that are plaguing you, then this is the post for you.Ĭonceptually headless Drupal is pretty simple. We are working on drafting a manifesto on GitHub.įor some background, see Notes and Discussion from DrupalCon Austin.Recently you must have heard of the term "headless Drupal". The intention of this working group is to discuss how Drupal core should change for the ability for many different presentation layers to interact with Drupal, especially client-side frameworks, not just Drupal's own theme system. We want an API for renderable structure and context-aware template-driven JSON representations of pages. We want Drupal to be the CMS of choice for client-side MVC frameworks.
