Headless Drupal: Architecture, Performance, Examples
In 2025, headless architecture is becoming one of the key trends in web development. Drupal, as one of the most powerful CMS platforms, is perfectly suited for creating modern, dynamic, and interactive web applications. Let's explore what headless Drupal is, how to integrate it with popular frontend frameworks, and what benefits it offers for your business.
What is Headless Drupal and Why It's Trending in 2025
Headless Drupal is an approach where Drupal is used exclusively as a content management system (CMS), while the frontend (user interface) is built using modern JavaScript frameworks such as React, Vue.js, or Angular.
Why it's popular:
- Flexibility: You can create any interface without being limited by standard Drupal templates
- Speed: JavaScript-based frontend ensures fast page loading and smooth interactions when properly optimized
- Omnichannel: Content from Drupal can be used across different platforms: websites, mobile apps, smart TVs, and more
Example: You're creating an e-commerce store. Instead of being limited to a standard interface, you can use React to create a dynamic and interactive shopping experience.
How to Integrate Drupal with Frontend Frameworks
Integrating Drupal with frontend frameworks like React or Vue.js enables you to create a powerful and modern user experience. Here's how it works:
- Using JSON:API: Drupal provides built-in JSON:API support, which allows data retrieval in JSON format. This is perfect for headless architecture.
- Frontend Development: Use React, Vue.js, or Angular to create the interface. For example, you can create a Single Page Application (SPA) that dynamically loads content from Drupal.
- Drupal Integration:
- Configure Drupal to export data via JSON:API
- Use libraries like Axios or Fetch API to retrieve data in the frontend application
- Set up routing and state management using Redux or Vuex
