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:

 '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.
