Building Better User Experiences with Headless WordPress and React

by Sreejith Partha

In the realm of web development, WordPress has long been a popular platform for creating and managing content-rich websites. However, as the demand for more dynamic and interactive user experiences has grown, developers have been looking for ways to decouple the WordPress backend from the front-end presentation layer. This has given rise to the concept of “Headless WordPress” By combining the power of WordPress as a content management system (CMS) with the flexibility and performance of React as a front-end framework, developers can create stunning and highly customizable websites. In this blog post, we’ll delve into the process of setting up a headless WordPress backend with a React frontend and provide detailed explanations and practical examples to help you get started.

Understanding Headless WordPress

Headless WordPress, also known as Decoupled WordPress, is an architecture that decouples the front-end presentation layer from the back-end WordPress content management system (CMS). In a traditional WordPress configuration, the front-end and back-end are tightly coupled, with WordPress handling both content management and website rendering.

In a headless WordPress architecture, the CMS is used exclusively for content management, while the front-end is developed separately using a different technology stack. The front-end can be developed using common JavaScript frameworks such as React, Angular or Vue.js, or any other technology. The front-end communicates with the WordPress back-end via a RESTful API or GraphQL API to fetch content.

Headless wordpressThis is how a Headless WordPress setup typically works:

  • Content management: WordPress remains the primary content management system, where administrators and content editors create, manage and publish content through the familiar WordPress interface.
  • Content delivery: Instead of generating HTML web pages on the server side, WordPress makes its content available through an API. This API allows the front-end application to request data (such as posts, pages, media, etc.) from WordPress.
  • Front-end development: the front-end development team creates a separate application using their preferred technology stack. This application retrieves data from the WordPress API and takes care of rendering web pages or interfaces. The front-end application has full control over the user interface, design, and interactions.
  • API integration: the front-end application communicates with the WordPress back-end through the API endpoints. It retrieves the required content and populates the user interface with it.


  • Flexibility: Headless WordPress allows developers to use any technology stack or framework to build the front-end, giving them the freedom to choose the best tools for their job.
  • Scalability: since the front-end and back-end are decoupled, both can be scaled independently depending on their own requirements. This allows for better performance and scalability of the overall system.
  • Rich user experiences: With Headless WordPress, developers can create highly interactive and dynamic user interfaces using modern JavaScript frameworks, resulting in engaging and responsive web experiences.
  • Reusability: By separating the content management system from the presentation layer, content can be easily reused across multiple platforms, including websites, mobile apps, IoT devices, or any other digital touchpoint.
  • Security: with a decoupled architecture, the attack surface is reduced as the front-end application is decoupled from the WordPress back-end, reducing potential vulnerabilities.

Headless WordPress provides the flexibility to build complex and interactive web applications while leveraging WordPress’ robust content management capabilities. It’s a powerful approach for developers who want to create modern and customized user experiences while benefiting from WordPress’ content management features.

Headless WordPress refers to the separation of the WordPress backend (responsible for content management) from the front-end presentation layer. In this architecture, WordPress serves as a headless CMS that provides an API for accessing content, while a separate frontend framework like React handles rendering and interaction.

Advantages of Headless WordPress with React

  • Flexibility: Headless WordPress allows developers to use any frontend technologies like React, Vue, Angular, etc. React, with its component-based architecture and rich ecosystem, offers great flexibility and facilitates the creation of highly interactive user interfaces.
  • Performance: decoupling the backend and frontend enables optimized performance. React’s efficient rendering and virtual DOM enable fast-loading pages, resulting in an improved user experience.
  • Adaptability: with a headless approach, you have complete control over the design of the frontend. The modular nature of React allows developers to create reusable components and apply custom styling to ensure a tailored user experience.

Setting Up a Headless WordPress Backend

Setting up a headless WordPress backend involves several steps to configure and optimize the WordPress CMS for API usage. In this section, we will expand on each step in detail.

Step 1: Installing and Configuring WordPress To set up a headless WordPress backend, you first need to install WordPress on your server or use a hosting provider that supports WordPress installations. Here are the basic steps to follow:

  • Choose a hosting provider or set up a local development environment.
  • Download the latest version of WordPress from the official website.
  • Upload the WordPress files to your server or set up a local development environment.
  • Create a MySQL database and user for your WordPress installation.
  • Run the WordPress installation script and provide the necessary configuration details, including database credentials, site title, and admin user credentials.

Once the installation is complete, you will have a functional WordPress CMS ready for customization.

Step 2: Enabling the REST API By default, WordPress provides a RESTful API that allows access to various resources, including posts, pages, categories, and more. However, depending on your WordPress version, you may need to install and activate the “WP REST API” plugin to enhance the API’s functionality and enable additional features and endpoints. Here’s how you can enable the REST API:

  • Log in to your WordPress admin dashboard.
  • Navigate to “Plugins” > “Add New.”
  • Search for “WP REST API” and install the plugin.
  • Activate the plugin.

Once activated, the REST API will be available, and you can start making API requests to retrieve content from your WordPress site.

Step 3: Creating Custom Post Types and Taxonomies (optional) WordPress allows you to create custom post types and taxonomies to organize and structure your content effectively. Custom post types allow you to define new content types beyond the default posts and pages. Taxonomies provide a way to categorize and classify your content.

To create custom post types and taxonomies, you can use plugins like “Custom Post Type UI” or “Advanced Custom Fields.” These plugins offer intuitive interfaces to define the structure and settings for your custom content types.

Here’s a general overview of the steps to create custom post types using the “Custom Post Type UI” plugin:

  • Install and activate the Custom Post Type UI plugin.
  • Go to “CPT UI” in the WordPress admin menu.
  • Click on “Add/Edit Post Types” to create a new custom post type.
  • Specify the labels, settings, and supported features for your custom post type.
  • Save the changes.

You can follow similar steps to create custom taxonomies using the same plugin or other taxonomy-related plugins.

Step 4: Extending the API with ACF to REST API Plugin If you use the Advanced Custom Fields (ACF) plugin to enhance the content structure of your WordPress site, installing the “ACF to REST API” plugin is highly recommended. This plugin allows the exposure of ACF data through the REST API, enabling seamless integration with your React frontend.

To extend the API with the “ACF to REST API” plugin, follow these steps:

  • Install and activate the “ACF to REST API” plugin.
  • In your ACF field groups, make sure to select the “Show in REST API” option for each field group or field you want to expose through the API.
  • Save your ACF settings.

With the “ACF to REST API” plugin enabled, you can access the additional data from your ACF fields through the REST API endpoints, making it available for consumption in your React frontend.

By following these steps, you can successfully set up a headless WordPress backend, enabling you to leverage the WordPress CMS

Building a React Frontend

Once you have set up your headless WordPress backend, you can proceed to build the React frontend that will consume the WordPress API and render the content. In this section, we will expand on the process of building a React frontend for your headless WordPress website.

Step 1: Setting Up a React Project To start building your React frontend, you need to set up a new React project. There are several ways to set up a React project, but one popular method is to use Create React App, a command-line tool that sets up a basic React project structure for you.

Here’s how you can set up a new React project using Create React App:

  • Install Node.js and npm (Node Package Manager) if you haven’t already.
  • Open your terminal or command prompt and run the following command to install Create React App globally.

npm install -g create-react-app

  • Once the installation is complete, navigate to the directory where you want to create your React project.
  • Run the following command to create a new React project.

npx create-react-app my-react-app

  • Replace “my-react-app” with the desired name for your project.
  • Once the project is created, navigate to the project directory:

cd my-react-app

You now have a new React project set up and ready to be customized.

Step 2: Fetching Data from the WordPress API To retrieve data from the WordPress API, you can use JavaScript libraries like Axios or Fetch. These libraries provide easy-to-use methods for making HTTP requests to your WordPress backend and handling the responses.

Here’s an example of how you can fetch blog posts from the WordPress API using Axios in a React component:

import React, { useEffect, useState } from 'react';
import axios from 'axios';

const BlogPosts = () => {
  const [posts, setPosts] = useState([]);

  useEffect(() => {
    const fetchPosts = async () => {
      try {
        const response = await axios.get('https://your-wordpress-site/wp-json/wp/v2/posts');
      } catch (error) {

  }, []);

  return (
      { => (
        <div key={}>
          <div dangerouslySetInnerHTML={{ __html: post.content.rendered }}></div>

export default BlogPosts;

In this example, we use the useEffect hook to fetch the blog posts from the WordPress API when the component mounts. The fetched data is stored in the posts state variable using the setPosts function. We then render the blog posts in the component, displaying the title and content for each post.

Step 3: Rendering WordPress Content in React Components Once you have fetched the data from the WordPress API, you can render it in your React components. You can create reusable components to display different types of content, such as blog posts, pages, or custom post types.

In the previous example, we created a BlogPosts component that fetches and renders the blog posts. You can customize this component further or create additional components to handle other types of content.

It’s important to note that the data structure returned by the WordPress API may vary depending on your specific content and customization. Make sure to explore the API response and adapt your React components accordingly to access the desired data fields.

By organizing your React components and leveraging React’s component-based architecture, you can create a modular and reusable codebase for your headless WordPress frontend.

Step 4: Styling and Customization To style your React frontend, you can use CSS frameworks like Bootstrap or Tailwind CSS, or you can write custom CSS styles. React allows you to apply styles inline or use CSS-in-JS solutions like Styled Components or Emotion.

Here’s an example of applying custom styles to the BlogPosts component using inline styles:

const BlogPosts = () => {

// ...

return (


{ => (

<div key={} style={{ marginBottom: '20px' }}>

<h2 style={{ fontSize: '24px', marginBottom: '10px' }}>{post.title.rendered}</h2>


style={{ lineHeight: '1.5', color: '#555', fontSize: '16px' }}

dangerouslySetInnerHTML={{ __html: post.content.rendered }}







In this example, we apply custom inline styles to the different elements within the component, such as the post title and content.

Alternatively, you can also use CSS modules, CSS preprocessors, or external CSS files to separate the styles from your components and maintain a more structured styling approach.

Step 5: Routing and Navigation (optional) If your headless WordPress website requires multiple pages or navigation between different sections, you can incorporate routing into your React frontend. React Router is a popular library for handling routing in React applications.

To set up routing in your React project, follow these steps:

  • Install React Router by running the following command:

npm install react-router-dom

  • Create a separate file to define your routes and configure the routing behavior. For example, you can create a file named App.js and define your routes like this:
import { BrowserRouter as Router, Switch, Route } from 'react-router-dom';

import Home from './components/Home';

import About from './components/About';

import Blog from './components/Blog';

const App = () => {

return (



<Route exact path="/" component={Home} />

<Route path="/about" component={About} />

<Route path="/blog" component={Blog} />





export default App;
  • In this example, we define three routes: the homepage (/), the About page (/about), and the Blog page (/blog). Each route is associated with a corresponding component.
  • Create the component files for each route, such as Home.js, About.js, and Blog.js, and define the content and functionality for each page.

With routing set up, you can navigate between different pages in your headless WordPress frontend by using <Link> components provided by React Router or programmatically redirecting to different routes.

Step 6: Optimizing Performance To optimize the performance of your React frontend, you can employ various techniques such as code splitting, lazy loading, and caching.

Code splitting allows you to split your React components into smaller chunks, so only the necessary code is loaded initially. This can significantly reduce the initial load time of your application. You can use tools like React.lazy and dynamic imports to implement code splitting.

Lazy loading involves loading components or data asynchronously, typically when they are needed. This can improve the perceived performance of your application by only loading content when it becomes relevant to the user. React.lazy, Suspense, and React Router’s <LazyLoad> component are useful tools for implementing lazy loading in React.

Caching can be implemented on both the server side and client side to reduce the number of API requests and improve the overall performance. Server-side caching can be achieved using tools like Redis or Memcached, while client-side caching can be implemented using libraries like SWR or Axios cache adapters.

Additionally, optimizing images, using browser caching, and minimizing network requests are also effective strategies to enhance the performance of your headless WordPress React frontend.

Step 7: Deployment Once your React frontend is built and tested locally, it’s time to deploy it to a hosting environment for public access. There are various hosting options available, including cloud hosting platforms like Netlify, Vercel, or AWS Amplify, or traditional web hosting providers.

To deploy your React application, follow the hosting provider’s documentation and guidelines for your chosen platform. Typically, you’ll need to build your React app for production using the command:

npm run build

This command generates an optimized and minified version of your React app ready for deployment. Then, you can upload the build output to your hosting environment or use CI/CD (Continuous Integration/Continuous Deployment) pipelines for automated deployments.

Ensure that your hosting environment is properly configured to handle routing, such as setting up redirect rules or using the appropriate server configurations like Nginx or Apache to ensure the React app is served correctly.

Building a React frontend for your headless WordPress website allows you to harness the flexibility and performance benefits of React while leveraging the powerful content management capabilities of WordPress. 

By setting up a React project, fetching data from the WordPress API, rendering content in React components, customizing the styling, implementing routing, optimizing performance, and deploying your application, you can create a seamless and engaging user experience for your headless WordPress website.

Remember to explore additional React libraries, tools, and best practices to further enhance your frontend development process and continually improve your headless WordPress application.

Advanced Techniques and Best Practices

Building a headless WordPress frontend with React opens up a realm of advanced techniques and best practices that can enhance the functionality, performance, and user experience of your application. In this section, we will explore some advanced techniques and best practices you can employ in your headless WordPress React frontend.

1. Server-side Rendering (SSR)

Server-side rendering is a technique that renders your React components on the server and sends the fully rendered HTML to the client. This approach can improve the initial load time and facilitate better SEO and social media sharing.

There are frameworks and libraries like Next.js and Gatsby that provide built-in support for server-side rendering in React applications. Next.js, for example, offers server-side rendering out of the box, allowing you to fetch data from the WordPress API on the server and pass it as props to your React components.

2. Static Site Generation (SSG)

Static site generation generates static HTML files at build time, which can be served directly to the client without the need for server-side rendering or API requests. This technique further improves performance and reduces server load.

Gatsby is a popular static site generator that works seamlessly with headless WordPress. It allows you to fetch data from the WordPress API during the build process and generate static pages for improved performance and caching.

3. Authentication and User Management

Implementing authentication and user management is crucial if you have areas of your headless WordPress site that require user login and access control. You can use authentication providers like JWT (JSON Web Tokens) or OAuth to handle user authentication and authorization.

For example, you can use plugins like “JWT Authentication for WP REST API” to enable JWT-based authentication with your headless WordPress backend. On the React frontend, you can store the JWT token securely (e.g., in local storage or a secure cookie) and include it in subsequent API requests to authenticate the user.

4. Handling Forms

Forms are a common element in websites, and handling form submissions in a headless WordPress React frontend requires additional considerations. You can use libraries like Formik or React Hook Form to manage form state, validation, and submission.

When submitting forms to your headless WordPress backend, you can utilize the WordPress REST API’s POST endpoints to create new posts, send contact form data, or perform any other desired actions. Make sure to handle form validation on the client-side as well as on the server-side to ensure data integrity and security.

5. Error Handling and Error Boundaries

Error handling is an essential aspect of any application. In React, you can use error boundaries to catch and handle errors that occur within your component tree. Error boundaries prevent the entire application from crashing and provide a graceful fallback UI when errors occur.

By wrapping components with error boundaries, you can display friendly error messages or redirect users to error pages when an error is encountered. This ensures a better user experience and helps in identifying and debugging issues.

6. Testing and Automated Testing

Testing is crucial for maintaining the quality and reliability of your application. React provides tools and libraries like Jest and React Testing Library for writing unit tests and integration tests for your components.

You can write tests to verify the behavior of individual components, simulate user interactions, and ensure that your React components interact correctly with the WordPress API. Automated testing helps catch bugs early, provides confidence in code changes, and improves the overall stability of your application.

7. Performance Optimization

Optimizing the performance of your headless WordPress React frontend is essential for delivering a fast and responsive user experience. Some performance optimization techniques include:

  • Code Splitting: Splitting your code into smaller chunks and loading them on-demand can improve initial load times.
  • Lazy Loading: Load content or components only when they are needed, reducing the initial payload.
  • Caching: Implement server-side caching, browser caching, or client-side caching to minimize unnecessary API requests and reduce server load.
  • Image Optimization: Optimize images for the web, compress them, and use lazy loading techniques to improve page load times.
  • Network Requests: Minimize the number of network requests by bundling and compressing assets and using techniques like HTTP/2 or CDN (Content Delivery Network) for faster content delivery.

By employing these optimization techniques, you can create a highly performant headless WordPress React frontend that provides an excellent user experience.

8. Continuous Integration and Deployment (CI/CD)

CI/CD pipelines automate the process of building, testing, and deploying your React frontend to production environments. Tools like Jenkins, CircleCI, or GitHub Actions can be used to set up CI/CD workflows for your headless WordPress React application.

CI/CD pipelines ensure that your code is thoroughly tested, and any changes to your application are deployed seamlessly to the production environment. This helps in maintaining the stability, reliability, and scalability of your application.

By incorporating advanced techniques and following best practices in your headless WordPress React frontend, you can create a powerful, scalable, and high-performing website. Whether it’s server-side rendering, static site generation, authentication, form handling, error handling, testing, performance optimization, or CI/CD, these techniques will elevate your development process and result in an exceptional user experience. Stay up-to-date with the latest developments in the React ecosystem, explore additional libraries and tools, and experiment with new approaches to continually enhance your headless WordPress React frontend.
