Step 1: Set Up a Basic WordPress Site
First, you need a standard WordPress installation. You can do this on a local server or live server. This installation is straightforward; you just need to set up WordPress as you normally would without worrying about the theme as it won’t be used for your site’s front-end.
Step 2: Choose and Configure a Headless Framework
Next, you need to decide on the technology for your front-end. Popular choices include Gatsby (React-based), Next.js (also React), Nuxt (Vue-based), and others. These frameworks allow you to build fast, modern web applications and static sites.
Download and install the framework of your choice and set it up in a development environment suitable for the technology. For instance, if you’re using Gatsby, you would set up a Node.js environment.
Step 3: Utilize the WordPress REST API
Headless WordPress relies on the WordPress REST API to serve content to the front-end. Ensure your WordPress installation is set up to serve data via REST API. By default, WordPress is equipped with REST API capabilities, so you may not need to perform additional setup. However, you might want to add custom endpoints or modify the existing structure with plugins or custom functions, depending on your project’s needs.
Step 4: Develop Your Front-end
- Fetching data from your WordPress site using the REST API. You’ll make HTTP requests to the endpoints that the WordPress API exposes.
- Creating application components. For instance, if you’re using React, you’ll write different components for each piece of content you want to display (posts, pages, comments, etc.).
- Handling routing in your application to correspond to different pieces of content from your WordPress site.
Step 5: Connecting Front-end with WordPress Data
Step 6: Deployment
Once your front-end application is ready and thoroughly tested, you can deploy it. The deployment process will depend on your chosen stack. For instance, a Gatsby site might be deployed to a static site hosting platform like Netlify, Vercel, or GitHub Pages.
Step 7: Security and Optimization
Finally, ensure that your application is secure. Implement necessary CORS policies to restrict unauthorized domain access to your REST API, and consider using security plugins or services to protect your WordPress back-end.
Also, optimize performance: Implement caching strategies, use a CDN for serving media files, and leverage additional site optimization tools compatible with your chosen technology stack.
