Sample Code: Front-End Post Listing Widget with React Components

1Create a New WordPress Plugin:

• Inside the WordPress plugins directory (wp-content/plugins), create a new folder for your plugin, let’s name it “react-post-listing-widget”.
• Create a main PHP file (e.g., react-post-listing-widget.php) and add the necessary plugin header information:

  <?php
  /*
  Plugin Name: React Post Listing Widget
  Description: A custom WordPress widget for listing recent posts using React.
  Version: 1.0
  Author: Your Name
  */
  
  // Plugin code will go here
  

2Set Up Your Plugin Structure:

• Inside the “react-post-listing-widget” folder, create a subdirectory named “src” for your JavaScript files.
• Install necessary dependencies and set up your build tools (e.g., Webpack, Babel) for compiling React components.

3Develop Your React Components:

• Create a React component named “PostListing” in a file named “PostListing.js” within the “src” directory.
• Here’s a sample code for the “PostListing” component:

  Jsx
  import React, { useState, useEffect } from 'react';
  
  const PostListing = () => {
    const [posts, setPosts] = useState([]);
  
    useEffect(() => {
      // Fetch recent posts from WordPress REST API
   	   fetch('/wp-json/wp/v2/posts')
    	    .then(response => response.json())
    	    .then(data => setPosts(data))
      	  .catch(error => console.error('Error fetching posts:', error));
    }, []);
  
    return (
      <div>
        <h2>Recent Posts</h2>
        <ul>
          {posts.map(post => (
            <li key={post.id}>
              <a href={post.link}>{post.title.rendered}</a>
            </li>
          ))}
        </ul>
      </div>
    );
  };
  
  export default PostListing;
  

4Integrate React with WordPress:

• Enqueue React and ReactDOM scripts in your plugin PHP file:

  <?php
  function enqueue_react_scripts() {
    wp_enqueue_script('react', 'https://unpkg.com/react@17/umd/react.development.js');
    wp_enqueue_script('react-dom', 'https://unpkg.com/react-dom@17/umd/react-dom.development.js');
  }
  add_action('wp_enqueue_scripts', 'enqueue_react_scripts');
  

5Build Your WordPress Widget:

• Register a new widget area in your plugin PHP file:

   'Post Listing Widget',
      'id' => 'post-listing-widget',
      'before_widget' => '<div id="%1$s" class="widget %2$s">',
      'after_widget' => '</div>',
      'before_title' => '<h2 class="widget-title">',
      'after_title' => '</h2>',
    ));
  }
  add_action('widgets_init', 'register_post_listing_widget');
  

6Render React Components in Your Widget:

• Use JavaScript to render your React components within the widget area:

  </div>';
    echo '<script src="' . plugins_url('/build/main.js', __FILE__) . '"></script>';
  }
  

7Test Your Plugin:

• Activate your plugin in the WordPress admin dashboard.
• Add the “Post Listing Widget” to a widget area in a WordPress theme.
