Next.js WordPress Tutorial

What is Next.js?

Next.js is an open-source React framework that allows developers to build server-rendered applications easily. It provides built-in features like static site generation and server-side rendering, which improve the performance and SEO of web applications. By simplifying the process of rendering React applications, Next.js makes it easier for developers to focus on building features rather than configuring the technical infrastructure.

What is a Framework?

A framework is a collection of tools and libraries designed to facilitate the development of software applications. It provides a reusable structure (like a blueprint) that developers can follow, which helps streamline the development process. Frameworks typically dictate the architecture of your application and come with conventions which can ease the setup.

Example of a Framework:

import React from 'react';
import { NextPage } from 'next';

const Home: NextPage = () => (
  <div>
    <h1>Welcome to Next.js!</h1>
  </div>
);

export default Home;

What is a Library?

A library is a collection of pre-written code that developers can use to perform specific tasks. Unlike frameworks, libraries do not dictate the overall structure of your application; instead, they provide functionality that you can call. You are in control of the flow and structure of your application when using a library.

Example of a Library:

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(<App />, document.getElementById('root'));

Difference Between Framework and Library

• Control Flow: In a framework, the framework is in control (inversion of control), while in a library, the developer is in control.
• Architecture: Frameworks provide a defined architecture, while libraries offer specific functions that can be called as needed.

Next.js WordPress Tutorial

In this Next.js WordPress tutorial, we'll show you how to set up a basic application that pulls data from a WordPress site using the REST API. This allows you to take advantage of Next.js's rendering capabilities while leveraging WordPress as a content management system (CMS).

Step 1: Setting Up Your Next.js Application

First, create a new Next.js application using the following command:

npx create-next-app my-next-app
cd my-next-app

Step 2: Fetching Data from WordPress

To use your WordPress data in the Next.js application, you can fetch data from the WordPress REST API. For example, to fetch posts, you can create a new page.

Create a new file at pages/posts.js:

import React from 'react';

const Posts = ({ posts }) => {
  return (
    <div>
      <h1>Posts</h1>
      {posts.map((post) => (
        <h2 key={post.id}>{post.title.rendered}</h2>
      ))}
    </div>
  );
};

export async function getStaticProps() {
  const res = await fetch('https://yourwordpresssite.com/wp-json/wp/v2/posts');
  const posts = await res.json();

  return {
    props: { posts },
  };
}

export default Posts;

Step 3: Running the Application

To run the application, use the command:

npm run dev

Visit http://localhost:3000/posts to see the posts fetched from your WordPress installation.

Important to Know

• This Next.js WordPress tutorial assumes that you have a working WordPress installation with the REST API enabled.
• Ensure that you replace https://yourwordpresssite.com with your actual WordPress URL.
• You can explore different endpoints from the WordPress REST API to fetch various data such as pages, categories, and tags.
