In modern web development, combining WordPress’s powerful CMS back end with a dynamic React front-end has become a popular approach. In a headless WordPress setup, WordPress runs as a back-end content store while a React app handles the user interfacertcamp.com. This decoupled WordPress architecture allows you to fetch content via the WordPress REST API or GraphQL and display it in any front-end, resulting in highly interactive, app-like websites. In fact, some headless WordPress sites have seen dramatic engagement gains: for example, a headless React-powered redesign of SoundGuys cut load times in half and drove a 40% longer time on page (with 20% more pageviews)drewl.com. Another case saw a 62% increase in user engagement after adding React-powered interactivitylinkedin.com. In this guide, we’ll explain what headless WordPress is, show why using React as the front-end can improve engagement, and walk through how to set up your own decoupled WordPress website. Let’s get started!
What is Headless WordPress?
“Headless WordPress” means using WordPress solely as a back-end CMS, completely decoupled from the front-endrtcamp.com. In a typical site, WordPress themes mix PHP and HTML to render pages. In a headless approach, WordPress only manages content and exposes it via APIs (JSON data) instead of HTML. For example, WordPress’s built-in REST API returns JSON rather than rendering pages on the servergatsbyjs.com. You could also install a plugin like WPGraphQL to expose a single /graphql endpoint. With these APIs, your React app can fetch posts, pages, images and other data from WordPress and display it however you like, even across multiple platforms. As Gatsby’s docs note, one big benefit is that content teams keep using the familiar WordPress admin, while developers use modern stacks (like React and GraphQL) to build the sitegatsbyjs.com. This separation of concerns makes it easier to scale content delivery and update the UI independently.
Why Use React with Headless WordPress?
Using a React front-end for your headless WordPress site comes with many advantages:
- Dynamic, Interactive UI: React’s component-driven model makes it easy to build rich interfaces (animations, live search, filtering, etc.) that WordPress themes alone can’t. Developers can use state, hooks, and modern JavaScript to create responsive pages.
- Performance Boost: A React app can be statically generated or use client-side routing for near-instant page loads. In one headless example (SoundGuys), cutting over to a React PWA halved the “Time To Interactive” and led to a 40% increase in time-on-page and 20% more pageviewsdrewl.com. Faster sites generally keep users engaged longer.
- Flexible Workflows: Content editors stick with WordPress’s intuitive interface, while developers work with React and tools like Node, npm, and Git. This decoupled workflow often speeds up development. For instance, a recent site restructure using React components for dynamic content saw user engagement jump 62%linkedin.com.
- Omnichannel Content: The same WordPress content can now power not just the website but also mobile apps or other channels, since it’s exposed via APIs. Major brands have adopted this: TechCrunch’s site uses headless WordPress with React/Redux and GraphQL to achieve sub-second page loads, enabling a blazing-fast reading experiencemultidots.com.
By combining WordPress’s ease-of-use with React’s interactivity, you get the best of both worlds. In short, a decoupled WordPress website with a React front end can create more engaging, app-like experiences for users, while keeping your backend simple.
How to Set Up a Headless WordPress Environment
To build a headless site, you first need a normal WordPress installation acting as the content back end. Key setup steps include:
- Install WordPress: Get WordPress from WordPress.org or your host, and install it as usual. (Tools like LocalWP or XAMPP can help you spin up a local WordPress instance for development.)
- Permalinks: In the WordPress dashboard, under Settings → Permalinks, choose “Post name” or another pretty URL. This ensures the REST API endpoints are available (e.g.
yourdomain.com/wp-json/wp/v2/posts). - Add Content: Create some posts, pages, categories, etc. in the dashboard so there’s content to fetch. WordPress will manage these as usual.
- Enable APIs: The WordPress REST API is built in. To use GraphQL instead, install and activate the WPGraphQL plugin. After activation, you can visit
yourdomain.com/graphqlin a browser and you should see a GraphQL interface (even if you get a syntax error message, it means the endpoint is working)wpgraphql.com. - Configure CORS (if needed): If your React app runs on a different domain/port during development, you may need to allow cross-origin requests on your WordPress site (e.g. via a plugin or server header) so that your frontend can fetch the API data.
- Test the endpoints: Try browsing to
yourdomain.com/wp-json/wp/v2/poststo see raw JSON of recent posts, or to/graphqlto run a test query.
These steps set up WordPress as a headless CMS. You now have an environment where WordPress stores and serves data, but doesn’t render the final HTML. Next, we’ll build the React app that will consume this data.
Creating a React Front-End
On the front-end side, create a React application that will fetch and display your WordPress content. First, ensure you have Node.js and npm installed (as recommended on the WPGraphQL tutorial site)wpgraphql.com. Then start a new React project. For example:
bashCopyEditnpx create-react-app my-headless-site
cd my-headless-site
npm start
This uses Create React App to scaffold a simple React project. By default it runs on http://localhost:3000 and shows a starter page. From here, you can build your components. For a headless site, you might create components like <PostsList /> or <Header /> and set up routes with React Router or a framework like Next.js (if you need server-side rendering).
When the development server is running (npm start), it will auto-reload as you change your code. Since the content comes from WordPress, you don’t need to hard-code it in React. Later, you’ll use fetch or a GraphQL client to pull data and fill your components. Until then, you can design your page structure and styles normally. (The official React docs and tutorials are great resources if you need guidance.)
Fetching WordPress Content via REST API or WPGraphQL
In React, you can fetch WordPress content either via the REST API or via GraphQL. Using the REST API: WordPress exposes endpoints like /wp-json/wp/v2/posts. For example, to get all posts:
jsCopyEditfetch('https://your-wordpress-site.com/wp-json/wp/v2/posts')
.then(response => response.json())
.then(posts => {
console.log(posts); // array of post objects
});
This JavaScript code makes an HTTP GET request to the WordPress JSON API. The response is parsed to JSON, giving you an array of post data. You could then store this in state (e.g. setPosts(posts) in a React component) and render it.
Using WPGraphQL: If you prefer GraphQL, all queries go through a single endpoint (e.g. https://your-wordpress-site.com/graphql)wpgraphql.com. You would send a POST request with a query string. For example:
jsCopyEditfetch('https://your-wordpress-site.com/graphql', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
query: `
query {
posts {
nodes {
id
title
date
}
}
}
`
})
})
.then(res => res.json())
.then(result => {
console.log(result.data.posts.nodes);
});
This code sends a GraphQL query for post IDs, titles, and dates. The WordPress WPGraphQL plugin handles it and returns the matching data. WPGraphQL tutorials (on wpgraphql.com) walk through building React/Apollo apps that fetch WordPress datawpgraphql.com.
Whether you use REST or GraphQL depends on your preference. REST has many built-in endpoints (for posts, pages, taxonomies, etc.), while GraphQL lets you specify exactly what fields you want in one request. Both methods give you JSON data that your React app can work with.
Displaying Posts in React
Once you have fetched data into your React app, you can render it in components. For example, suppose you fetched posts and stored them in state like posts. You might display them like this:
jsxCopyEditimport React, { useState, useEffect } from 'react';
function PostsList() {
const [posts, setPosts] = useState([]);
useEffect(() => {
fetch('https://your-wordpress-site.com/wp-json/wp/v2/posts')
.then(res => res.json())
.then(data => setPosts(data));
}, []);
return (
<div>
{posts.map(post => (
<article key={post.id}>
<h2>{post.title.rendered}</h2>
<div dangerouslySetInnerHTML={{ __html: post.excerpt.rendered }} />
{/* You can also display featured images, dates, etc. */}
</article>
))}
</div>
);
}
In this example, we use useEffect to fetch posts after the component mounts, then store them in posts. We map over posts and render each one. Note that WordPress returns HTML strings for titles and content (e.g. post.title.rendered), so we use dangerouslySetInnerHTML to inject that HTML safely. You could similarly use GraphQL and store result.data.posts.nodes into state.
This simple component will list your latest posts by pulling from the WordPress API. You can create additional components (e.g. single post view, navigation menus, etc.) that fetch and display other WordPress data in the same way.
Authentication and Deployment Tips
- Authentication: If your front-end only reads public content, no auth is needed for GET requests. However, if you want your React app to create or update content on WordPress, you’ll need authentication. WordPress supports various methods: cookie-based auth (for logged-in users), Application Passwords (built-in since WP 5.6), or JWT/OAuth plugins for the REST API. For WPGraphQL, you can also use JWT or the default cookie auth. If you add auth headers to your fetch requests, make sure to secure them properly. For example, using HTTPS and environment variables.
- Deployment: When you’re ready to go live, you’ll have two parts to host. The WordPress back end can stay on any PHP host (shared hosting, WP Engine, Kinsta, etc.) or even managed WordPress platforms. The React front end can be deployed as a static/Node app. Popular choices are Vercel or Netlify, which automatically build your React app and serve it with a global CDN. Just point your domain to the front end, and configure your WordPress URL (often via an environment variable like
REACT_APP_API_URL). You can also use services like Heroku or AWS. For local development, tools like LocalWP (for WordPress) and Create React App (for React) work well together. - CORS & Environment: If your React app and WordPress are on different domains, ensure CORS headers are set on the WordPress server to allow cross-origin API calls. Also store API endpoints and secrets in environment variables rather than hard-coding them. For example, use
.env.localin React forREACT_APP_API_URL=https://your-wordpress-site.comso you can easily switch between dev and production.
By handling authentication securely and choosing the right hosting, you can deploy a headless WordPress site that’s fast, secure, and scalable.
Pros and Cons of Headless WordPress
Pros:
- Performance: You can optimize or statically generate the React front-end, leading to faster page loads and better Core Web Vitals (one project saw page load times cut in half). Static assets and reduced PHP processing make for smoother UX.
- Flexible Tech: Developers can use React (or Vue, Angular, etc.) and modern JavaScript tools to build features that aren’t possible with PHP templates. You’re not limited by WordPress themes or PHP.
- Scalability: The front-end can be scaled independently (e.g. served from a CDN), and the same content can drive multiple interfaces (web, mobile apps, etc.). Enterprise sites like Al Jazeera even use three-layer setups (WP back-end, GraphQL layer, React front-end) to serve content globallymultidots.com.
- Security: A static front-end has fewer attack surfaces (no open database on the front-end server). For example, Gatsby-powered headless sites have no direct DB or PHP on the public sitegatsbyjs.com. You’re only exposing an API, which can be locked down.
Cons:
- Complexity: You now have two codebases to manage (WordPress PHP and React JavaScript). It requires more setup and familiarity with API development.
- Lost WP Features: Some WordPress features (like certain plugins or theme-based preview) may not work out of the box. Live preview in the editor is harder, and some SEO plugins need extra configuration.
- Learning Curve: Non-technical content editors can no longer tweak templates; everything must be coded. Developers need to know React and how to work with REST/GraphQL APIs.
- Potential SEO/Rendering Issues: By default a React SPA might not be indexed as easily as a server-rendered page. You may need server-side rendering (e.g. using Next.js) or prerendering to ensure SEO performance.
Overall, the headless approach trades off some simplicity for greater flexibility and performance. It shines when you need advanced UI features or high performance, but it may be overkill for a simple blog.
