Headless WordPress Theme is an alternative to traditional server-side applications. Instead of being built and controlled on the server, the application interface is produced and handled directly in the client browser. After pulling content from WordPress, the browser’s JavaScript application provides this interface. Client-side or decoupled development is another term for this. 

By doing so, you can get around WordPress’ front-PHP-based end’s interface. The real CMS, the body, is controlled remotely by an external app. Because the API handles communication between the web app and the server-side CMS, this style of app development is also known as API-driven development.

The term “headless” in WordPress has nothing to do with any scary figure that lives in the forest.Headless WordPress Themes is a cutting-edge technological approach that produces a generic WordPress backend that can function with any frontend, regardless of the underlying frameworks. 

Headless CMS Development The REST API is used by WordPress to communicate between the backend and frontend of a web application and to deliver requests. It has a single requirement that both the backend and the frontend speak the same JSON language.

What is React?

At the visible layer, React delivers an incredibly simple yet attractive frontend for your audience to utilize your app. React is a Facebook-backed open-source JavaScript framework with a large community that helps you to troubleshoot any mistakes that come up during development.

Steps to Implement Headless WordPress Using React

Step 1: Setting Up a WordPress Site

The first step in integrating React in WordPress with Headless CMS is to set up a WordPress site, which will give all of the necessary resources for creating front-end React apps. Begin by using Git to install the WP-Rest API plugin’s zip file, and then upload that zip folder to your WordPress plugins folder. 

Allow the WordPress Rest API into your React.JS WordPress website as soon as the file is posted by activating the plugin. Visit settings at Permalinks and choose Post name or Custom Structure. Install the Postman chrome extension because we’ll be working with API calls. When you’re in the Postman, input the URL in the following format:

https://example.com/wp-json/wp/v2/posts .This link will assist you in importing data into your WordPress site.

Custom Post Type UI Plugin

Download the Custom Post Type UI plugin to build custom post types, and copy it. When you utilize WordPress with React in the following phase, these posts will appear. Install the plugin and activate, start creating new post types. 

Complete data in the Post Type Slug with the name of the custom post to start. If you wish to utilize Headless WordPress, make sure the Show in the REST API option is set to true. To receive the information you desire via the REST API, click all of the choices.

As soon as you click save, a new option will appear in the sidebar select it to add a new book to your custom post type. Click the URL inside Postman, to see if the data is available through API. Both plugins must be installed and activated. Within your custom post type, you will see a new field. When using React with WordPress to deliver data, this is all you have to do for a ReactJS application.

 Step 2: Getting Started With React

The following must be installed in order to set up the React application.

  • Node.JS & NPM.
  • Text Editor like Visual Studio Code.
  • Git for version controlling

Once you have installed all of the requirements, you are ready to go. 

  1. Open the command line and type the following code to start the project using React.JS WordPress.

npx create-react-app frontend

  1. Now that the app has been created, move to the app folder and run the command below to install the Axios package for API calls.

npm i Axios

  1. In your chosen text editor, click on the folder. Run the command to start the application. 

npm start

  1. Create a new folder called ‘components’ inside the src folder, and a new file called ‘components’ inside the ‘components’ folder. 

Step 3: Rendering Post Data on React.JS

It is time to render post data on React.JS using WordPress and react. Utilize a particular code to access the REST API end-point and show the JSON post data obtained from the WordPress REST API.

Step 4: Displaying Post Data on React.JS

Display the post data once it’s been rendered in React.JS. You have the option of displaying the data in the parent component or creating a new one. Make changes to the render function and put everything together. That concludes our topic.
