What is a Decoupled Frontend?

A decoupled frontend refers to a web development architecture where the frontend (client-side) and backend (server-side) are separated from each other. This approach allows developers to build the user interface independently from the backend services. In the context of Headless Drupal, the backend is managed by Drupal, serving content through APIs, while the frontend can be developed using any technology stack, such as React, Vue.js, Angular, or even static site generators.

Benefits of Decoupled Frontends

There are several benefits to using a decoupled frontend architecture:

• Flexibility: Developers can choose the best technology for the frontend without being tied to the backend technology.
• Performance: The frontend can be optimized independently for performance, leading to faster load times.
• Scalability: The architecture can scale easily since both the frontend and backend can be optimized separately.
• Improved Collaboration: Frontend and backend teams can work simultaneously, leading to faster development cycles.

Setting Up a Decoupled Frontend with Headless Drupal

Setting up a decoupled frontend with Headless Drupal involves a few key steps:

1. Install Drupal and enable RESTful Web Services.
2. Create content types and add some content.
3. Configure permissions for the REST API.
4. Develop your frontend using your preferred framework.

Below is a brief example of how to create a simple REST API with Drupal.

Example Frontend Implementation

You can use any frontend framework to consume the API provided by Drupal. Below is a basic example using React to fetch content from a Drupal REST API.

                    import React, { useEffect, useState } from 'react';

                    const App = () => {
                        const [data, setData] = useState([]);

                        useEffect(() => {
                            fetch('https://your-drupal-site.com/jsonapi/node/article')
                                .then(response => response.json())
                                .then(data => setData(data.data));
                        }, []);

                        return (
                            

                                
Articles
                                

                                    {data.map(article => (
                                        
{article.attributes.title}
                                    ))}
                                
                            
                        );
                    };

                    export default App;
                

Conclusion

Decoupled frontends offer a modern approach to web development, allowing for greater flexibility, performance, and scalability. By leveraging Headless Drupal, developers can create robust applications that separate the concerns of content management and user interface design.

With the right tools and frameworks, it’s possible to build a powerful frontend that communicates seamlessly with a Drupal backend, providing a rich user experience.
