WordPress Plugin Development with React, Vue, and Tailwind

The WordPress ecosystem has evolved to embrace modern JavaScript frameworks and CSS tools, enabling developers to build dynamic admin interfaces and Gutenberg blocks with the same tools used in standalone applications. Whether you’re creating a complex Gutenberg block with React, a Vue-powered admin dashboard, or a Tailwind-styled plugin, integrating these frameworks requires careful setup to ensure compatibility and performance.

This guide provides sequential instructions for WordPress Plugin Development and merging React, Vue and Tailwind CSS into WordPress plugins. It also includes instructions for Gutenberg blocks administration pages and style guidelines.

Why Use Modern Frameworks For WordPress Plugin Development?

1. Enhanced User Experience: Reactive interfaces improve usability.
2. Code Maintainability: Component-based architectures simplify scaling.
3. Performance: Modern tools optimize asset loading and rendering.
4. Developer Familiarity: Leverage existing knowledge of React/Vue.

1. Integrating React into Gutenberg Blocks

WordPress block editor (Gutenberg) is built with React, making it the natural choice for custom blocks.

Step 1: Set Up the Development Environment

Use the official @wordpress/create-block package to scaffold a block:

// Bash Code

npx @wordpress/create-block my-custom-block --template @wordpress/create-block-tutorial-template

This code generates a block with the following:

• A React component in src/index.js.
• Webpack configuration for compiling JS/SCSS.
• Automatic asset enqueuing via block.json.

Step 2: Build a Custom Block

Edit src/edit.js to create a dynamic block:

// jsx Code

import { useBlockProps } from '@wordpress/block-editor';  

import { TextControl } from '@wordpress/components';  

export default function Edit({ attributes, setAttributes }) {  

    return (  

        <div {...useBlockProps()}>  

            <TextControl  

                label="Enter Text"  

                value={attributes.text}  

                onChange={(text) => setAttributes({ text })}  

            />  

        </div>  

    );  

}

Step 3: Enqueue Assets

WordPress automatically enqueues JS/CSS defined in block.json:

// json Code

{  

    "name": "my-custom-block",  

    "editorScript": "file:./build/index.js",  

    "editorStyle": "file:./build/index.css",  

}

Key Dependencies:

• @wordpress/blocks: Register blocks.
• @wordpress/components: Use pre-built UI elements.
• `@wordpress/scripts**: Compile code (Babel, Webpack).

Build Command:

// Bash Code

npm run build

2. Using Vue.js in Admin Pages

For admin interfaces outside Gutenberg, Vue.js offers a lightweight alternative.

Step 1: Set Up a Vue Project

Initialize a Vue app with Vite:

// Bash Code

npm create vue@latest my-admin-app

Configure vite.config.js to build on the WordPress plugins directory:

// Js Code

export default {  

    build: {  

        outDir: '../wp-content/plugins/my-plugin/admin',  

        emptyOutDir: true,  

    }  

};

Step 2: Create a Vue Component

Build a dashboard component in src/App.vue:

// Vue Code

<template>  
    <div id="my-vue-app">  
        <h1>{{ title }}</h1>  
        <button @click="fetchData">Load Data</button>  
        <ul>  
            <li v-for="item in items" :key="item.id">{{ item.name }}</li>  
        </ul>  
    </div>  
</template>  

<script>  
export default {  
    data() {  
        return {  
            title: 'Vue Admin Dashboard',  
            items: []  
        };  
    },  
    methods: {  
        async fetchData() {  
            const response = await fetch('/wp-json/my-plugin/v1/data');  
            this.items = await response.json();  
        }  
    }  
};  
</script>  

Step 3: Enqueue Vue Assets in WordPress

In your plugin PHP file, enqueue the compiled assets:

// PHP Code

add_action('admin_enqueue_scripts', 'enqueue_vue_app');  

function enqueue_vue_app($hook) {  

    if ($hook !== 'toplevel_page_my-plugin') {  

        return;  

    }  

    wp_enqueue_script(  

        'my-vue-app',  

        plugins_url('admin/assets/index.js', __FILE__),  

        array(), // No dependencies (Vue is bundled)  

        filemtime(plugin_dir_path(__FILE__) . 'admin/assets/index.js')  

    );  

    wp_enqueue_style(  

        'my-vue-app-style',  

        plugins_url('admin/assets/style.css', __FILE__)  

    );  

}

Step 4: Mount Vue to the Admin Page

Add a container to your admin page template:

// PHP Code

function render_admin_page() {  

    echo '<div id="my-vue-app"></div>';  

} 

Note: For better integration, use wp_localize_script() to pass data from PHP to Vue:

// PHP Code

wp_localize_script('my-vue-app', 'wpData', [  

    'nonce' => wp_create_nonce('wp_rest'),  

    'apiUrl' => rest_url('my-plugin/v1/data')  

]);

3. Adding Tailwind CSS to a Plugin

Tailwind CSS simplifies styling without writing custom CSS.

Step 1: Install Tailwind

Initialize Tailwind in your plugin directory:

// Bash Code

npm install -D tailwindcss postcss autoprefixer  

npx tailwindcss init -p

Step 2: Configure tailwind.config.js

Purge unused styles to reduce file size:

// Js Code

module.exports = {  

    content: [  

        './admin/**/*.php',  

        './blocks/**/*.js',  

    ],  

    theme: {  

        extend: {},  

    },  

    plugins: [],  

}

Step 3: Create a Tailwind Stylesheet

Add src/input.css:

// CSS Code

@tailwind base;  

@tailwind components;  

@tailwind utilities;

Step 4: Compile CSS

Update package.json to build Tailwind:

// JSON Code

"scripts": {  

    "build:css": "tailwindcss -i src/input.css -o build/tailwind.css --minify"  

} 

// Bash Code

npm run build:css

Step 5: Enqueue Tailwind in WordPress

Load the compiled CSS only where needed:

// PHP Code

add_action('admin_enqueue_scripts', 'enqueue_tailwind');  

function enqueue_tailwind($hook) {  

    if ($hook === 'toplevel_page_my-plugin') {  

        wp_enqueue_style(  

            'my-tailwind',  

            plugins_url('build/tailwind.css', __FILE__)  

        );  

    }  

}

Best Practices

• Dependency Management:
  • Use wp-element as a dependency for React components to avoid bundling duplicate libraries.

// PHP Code

wp_enqueue_script('my-react-app', $js_path, array('wp-element'), $version);

• Code Splitting:
  • Split Vue/React code into chunks using dynamic imports:

// JS Code

const SettingsPage = () => import('./SettingsPage.vue');

• Security:
  • Verify nonces in REST API endpoints:

// PHP Code

register_rest_route('my-plugin/v1', '/data', array(  

    'methods' => 'GET',  

    'callback' => function ($request) {  

        if (!wp_verify_nonce($request->get_header('X-WP-Nonce'), 'wp_rest')) {  

            return new WP_Error('forbidden', 'Unauthorized', array('status' => 403));  

        }  

        // Return data  

    },  

));

• Performance:
  • Use lazy loading for non-critical components.
  • Cache compiled assets using filemtime() for versioning.

Troubleshooting Common Issues

• React/Vue Not Rendering:
  • Ensure the DOM container exists before initializing the app.
  • Check in the browser console for JavaScript errors.
• Dependency Conflicts:
  • Use wp.dependencies to check registered scripts:

// Bash Code

wp script list

• Tailwind Styles Missing:
  • Verify the content paths in tailwind.config.js.
  • Rebuild CSS after markup changes.
• CORS Errors in REST API:
  • Pass the X-WP-Nonce header in API requests:

fetch('/wp-json/my-plugin/v1/data', {  

    headers: {  

        'X-WP-Nonce': wpData.nonce  

    }  

});

Real-World Example: Analytics Dashboard Plugin

Tech Stack:

• Gutenberg Block (React): Displays real-time stats in the editor.
• Admin Page (Vue): Interactive charts for data visualization.
• Styling (Tailwind): Consistent UI across the plugin.

Workflow:

• Users configure settings via a React block.
• Data is fetched via the REST API and displayed in Vue charts.
• Tailwind ensures a cohesive design without conflicting with admin CSS styles.

Implementation Steps:

• Gutenberg Block: Create a block that allows users to select data ranges and display stats.
• Vue Admin Page: Use Vue to create a dashboard that fetches and visualizes data based on user input from the block.
• Tailwind CSS: Use Tailwind to style both the block and the admin page to ensure a modern look and feel.
