How to Build a Headless WordPress Site in 2024 With JSON & Plugins

Headless WordPress allows developers to utilize multiple technologies for the front end and back end of a project. This strategy is gaining traction since it provides increased performance advantages, control, and flexibility.

Using JSON and plugins is essential for this setup. Data may be easily transferred between systems thanks to the lightweight JSON (JavaScript Object Notation) data format. Plugins extend WordPress’s functionality, making headless setups possible.

In a headless WordPress setup, the CMS (WordPress) manages the backend, including content creation and storage. The frontend, which displays the content to users, is built using other technologies such as React, Vue, or Angular. This separation allows developers to create faster, more dynamic websites and applications.

The headless approach has several benefits. Firstly, it allows developers to use modern JavaScript frameworks, which are known for their speed and flexibility. Second, because the frontend and backend may be optimized independently, performance is enhanced.

Thirdly, since the content management system isn’t directly accessible over the internet, security is improved.

JSON plays a crucial role in this setup. It is a text format that is simple for computers to understand and produce, and for humans to read and write. In a headless WordPress system, data is transferred between the frontend and backend using JSON.

Plugins are also important. They extend the functionality of WordPress, enabling it to serve as a headless CMS. For example, plugins can help with enabling the WordPress REST API, which is essential for a headless setup.

Understanding Headless WordPress

Headless WordPress is the name of a content management system (CMS) in which the front end and back end are separate. This means that WordPress handles the content management, while the presentation layer is managed by a different technology stack.

Difference Between Traditional and Headless WordPress

In a traditional WordPress setup, the CMS handles everything from content creation to presentation. This means that WordPress is responsible for both managing the content and displaying it to the users. However, in a headless WordPress setup, these two functions are separated. WordPress is only responsible for managing the content, and the frontend is built using other technologies.

In a headless setup, content is created and stored in WordPress. This content is then served to the frontend via an API, such as the WordPress REST API. The frontend fetches this content and displays it to the users. Because of this division, frontend developers can use contemporary JavaScript frameworks like , Vue, or React.

Use Cases for Headless WordPress

Headless WordPress is suitable for a variety of projects. Some common use cases include:

• Single Page Applications (SPAs): Headless WordPress can be used to feed data to SPAs built with frameworks like React or Vue. These applications can fetch data from the WordPress backend via the API and display it dynamically.
• Mobile Apps: Developers can use WordPress as a content hub for mobile apps. The apps can fetch data from the WordPress backend via the API and display it on mobile devices.
