🚀 My First Headless WordPress Project with Next.js and GraphQL

🌐 Introduction

Modern web development is moving toward faster, scalable, and API-driven architectures. In this project, I built a Headless WordPress system using Next.js and GraphQL, separating the backend and frontend completely.

This approach removes theme limitations and gives full control over performance and UI design.

🧠 What is Headless WordPress?

Headless WordPress means:

• WordPress is used only as a content management system (CMS)
• Frontend is built separately using Next.js
• Data is fetched using GraphQL API

👉 In this project setup:

• Backend CMS → WordPress
• API Layer → WPGraphQL
• Frontend → Next.js

⚙️ Why I Used GraphQL Instead of REST

GraphQL gives more control over data fetching compared to REST APIs.

🚀 Benefits:

• Fetch only required data
• Single API endpoint (/graphql)
• Faster performance
• Cleaner frontend code
• Better scalability

🔌 WordPress Plugins Used

🧩 WPGraphQL

Enables GraphQL API in WordPress.

👉 Endpoint:

http://localhost/headless-wp-backend/graphql

🖼️ Advanced Custom Fields (ACF)

Used for:

• Custom post fields
• Flexible content structure
• Dynamic layouts

🔍 Yoast SEO (Optional)

Used for:

• Meta titles & descriptions
• Sitemap generation
• SEO optimization

💻 Next.js Setup Commands

 

📦 Create Project

npx create-next-app@latest headless-wordpress-graphql

📁 Move into project

cd headless-wordpress-graphql

▶️ Run development server

npm run dev

👉 Frontend runs at:
http://localhost:3000/
