How to Build an Admin Page Using React in WordPress

Creating a custom admin page using React in WordPress can enhance the functionality and user experience of your site. In this guide, we’ll use @wordpress/element for React, and @wordpress/components for UI elements. We’ll also set up a minimal workable Webpack configuration.

Step 1: Install Necessary Packages

First, ensure you have Node.js and npm installed. Then, install the required packages:

npm install @wordpress/element @wordpress/components @babel/preset-react @babel/preset-env webpack webpack-cli webpack-dev-server babel-loader --save-dev

Step 2: Set Up Your Project Structure

Create the following directory structure:

├── admin
   ├── build
   └── src
       └── index.js
├── package.json
├── webpack.config.js
└── wp-react.php

Step 3: Configure Webpack

Create webpack.config.js with the following configuration:

const path = require('path');

module.exports = {
    entry: './admin/src/index.js',
    output: {
        path: path.resolve(__dirname, 'admin/build'),
        filename: 'bundle.js'
    module: {
        rules: [
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-env', '@babel/preset-react']
    devServer: {
        contentBase: path.join(__dirname, 'admin/build'),
        compress: true,
        port: 9000

Step 4: Create React Component

In admin/src/index.js, create a simple React component:

import { render } from '@wordpress/element';
import { Button } from '@wordpress/components';

const App = () => (
        <h1>My Admin Page</h1>
        <Button variant="primary" className="button default">Click Me</Button>

render(<App />, document.getElementById('admin-page'));

Step 5: Set Up package.json

In your package.json, add scripts for building and watching your files:

  "name": "wp-react",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "build": "webpack --mode production",
    "watch": "webpack --mode development --watch"
  "keywords": [],
  "author": "Kamal Hosen",
  "license": "GPL-v2-or-later",
  "devDependencies": {
    "@babel/preset-env": "^7.24.7",
    "@babel/preset-react": "^7.24.7",
    "@wordpress/components": "^28.2.0",
    "@wordpress/element": "^6.2.0",
    "babel-loader": "^8.3.0",
    "webpack": "^5.92.1",
    "webpack-cli": "^4.10.0",
    "webpack-dev-server": "^3.11.3"

Step 6: Enqueue Your Scripts in WordPress

In my-plugin.php, enqueue the compiled JavaScript file:

 * Plugin Name: WP React
 * Description: A simple plugin to demonstrate how to use React in WordPress.
 * Version: 1.0.0
 * Author: Kamal Hosen
 * Author URI:
 * License: GPL2
 * License URI:
 * Text Domain: wp-react
 * Domain Path: /languages
 * Requires at least: 5.2
 * Requires PHP: 7.2

function wp_react_enqueue_scripts() {
        plugins_url('admin/build/bundle.js', __FILE__),
        ['wp-element', 'wp-components'],
        filemtime(plugin_dir_path(__FILE__) . 'admin/build/bundle.js'),
add_action('admin_enqueue_scripts', 'wp_react_enqueue_scripts');

function wp_react_admin_page() {
        'WP React Admin Page',
        'WP React',
add_action('admin_menu', 'wp_react_admin_page');

function wp_react_render_admin_page() {
    echo '<div id="admin-page"></div>';

Step 7: Build and Watch Your Project

Run the following commands to build and watch your project:

npm run build
npm run watch


By following these steps, you can set up a React-based admin page in WordPress, leveraging modern JavaScript development tools like Webpack and Babel. This setup ensures your code is modular, maintainable, and easy to extend. Happy coding!
