Headless-wordpress-development

One of the many useful features provided by Headless WordPress Development is the Rest API. It allows developers to create interesting plugins and themes, as well as use the WordPress CMS to power third-party apps. The content management system is also created in current web apps to manage the website’s content. This may increase the developer’s workload. Because the Rest API provides so many options, one may consider integrating WordPress with React as a headless CMS for their JavaScript-based online application.

What Is Headless WordPress?

The term “headless” does not imply that the CMS does not have a header section. It means that you may utilize the CMS as a general content management system regardless of the front-end technology employed. Rest API allows developers to communicate with interfaces from other technologies as long as they both speak the same JSON language. The APIs of WordPress returns the data in JSON format, that is compatible with a broad range of web technologies. JSON is a text-based format of JavaScript objects that contains key-value pairs of data.

The benefit of Using Headless WordPress CMS

WordPress, as an open-source platform, provides a lot of versatility in terms of creating any type of website. Using WordPress as a headless CMS allows you to use any web technology to build the front-end of your online application and manage its content using one of the most popular CMS. 

You could find yourself in a position where you need to add a blog feature to an existing React or Angular web project. Instead of building a full-fledged content management system in the local framework, utilize the Rest API to manage content with the headless WordPress CMS.

Setting up a WordPress Site

By configuring the WordPress site, which will serve as a data source for our React frontend application. Download the WP-Rest API plugin’s zip file from git and place it in the plugins folder of your WordPress installation. Activate the plugin when the file has been uploaded. 

Within your WordPress website, this will enable the WordPress Rest API. Go to Permalinks Settings and choose either Post name or Custom Structure. Because we will be working with API requests, install the Postman Chrome plugin. 

Enter the URL in the following format in the Postman:

https://example.com/wp-json/wp/v2/posts

The given URL will retrieve the data from your WordPress site’s posts. Create fully customized posts using the Custom Post Type UI plugin. When we utilize WordPress with React in the following phase, this custom post will be shown. After you have installed and activated the plugin, go ahead and create a new post type. Type the name of your custom post in the Post Type Slug field. 

Make sure the Show in REST API option is checked, as well as the REST API base slug. If you want to utilize WordPress as a headless CMS, you will need to do this. Fill in all of the boxes for the data you want to retrieve via the REST API.  After you have saved your modifications, you will see that the sidebar has been updated with a new option. To add the new Book to your custom post type, click on it.

Getting Started with React

What’s React.JS?

Facebook and the developer community maintain React, a JavaScript library for the web. JavaScript is a strong tool for web development, and there are a number of libraries built in the language to improve the functionality of websites. React.JS is primarily used to create quick, reliable, and dynamic single-page apps.

Setting up React App

The following requirements must be installed on your computer in order to develop React applications.

  • NPM and Node. JS.
  • Sublime Text or Visual Studio Code are two examples of text editors.
  • Git is a version control system (Optional)

After you have set up the environment, enter the command prompt and type the following code to make a React.JS project. cd (change directory) to the application folder and enter the following command to install the Axios package for API calls after the app has been developed.

Rendering Post Data on React.JS

We will get the data via the WordPress Rest API in the Book.js file. The code that calls the Rest API end-point and shows the data in JSON format. Because App.js is where our web application starts, it is critical to include the “Books” components in this file.

Displaying Post Data on React.JS

By putting the code within the render method, the data may be shown. We will construct a new component called ‘BookItems.js’ instead of showing data. Change the render method inside Bookk.js. Now, render the BookItems component, Inside the BookItems.js add the code.
