How to Create a Multi-Page Application with React and Next.js

With the rise of modern web applications, the demand for efficient, high-performance, and user-friendly interfaces has never been greater. React, a popular JavaScript library for building user interfaces, combined with Next.js, a powerful framework for server-rendered React applications, provides a robust solution for creating multi-page applications (MPAs). In this article, we will explore how to leverage React and Next.js to build a multi-page application, complete with clear code examples and actionable insights.

What is a Multi-Page Application (MPA)?

A multi-page application is a web application that consists of multiple, standalone HTML pages. Each page is loaded independently and can feature different layouts and content. Unlike single-page applications (SPAs), which load a single HTML page and dynamically update the content, MPAs often offer better performance for SEO and can handle larger volumes of content more effectively.

Use Cases for Multi-Page Applications

E-commerce Websites: MPAs are ideal for online stores where each product or category can have its own dedicated page.
Blogs and News Sites: These platforms often contain numerous articles and sections that benefit from individual pages.
Corporate Websites: Companies may need separate pages for services, about sections, contact forms, etc.
Documentation Sites: Technical documentation often requires distinct pages for each topic or section.

Setting Up Your Next.js Project

Before diving into coding, let's set up a new Next.js application. Make sure you have Node.js installed on your machine. You can create a new Next.js app by running the following command:

npx create-next-app my-multi-page-app
cd my-multi-page-app

This command sets up a new Next.js project in a directory called my-multi-page-app.

Project Structure

Once your project is created, you'll see a folder structure like this:

my-multi-page-app/
├── pages/
│   ├── index.js
│   └── _app.js
└── public/

The pages directory is where you'll define your application’s routes. Each file in this directory corresponds to a route in your application.

Creating Multi-Page Routes

In Next.js, creating new pages is as simple as adding new files to the pages directory. Let's create a few pages for our application.

Step 1: Create New Pages

Create a new file for the "About" page:

touch pages/about.js

Add the following code to about.js:

import Link from 'next/link';

const About = () => {
    return (
        <div>
            <h1>About Us</h1>
            <p>Welcome to our multi-page application built with Next.js!</p>
            <Link href="/">Go back to Home</Link>
        </div>
    );
};

export default About;

Step 2: Update the Home Page

Now, let’s modify the default home page (index.js) to include a link to the "About" page. Update index.js:

import Link from 'next/link';

const Home = () => {
    return (
        <div>
            <h1>Welcome to My Multi-Page App</h1>
            <Link href="/about">Learn more About Us</Link>
        </div>
    );
};

export default Home;

Step 3: Create Additional Pages

You can easily create more pages. For instance, let’s add a "Contact" page. Create a new file named contact.js in the pages directory:

touch pages/contact.js

Add the following content to contact.js:

import Link from 'next/link';

const Contact = () => {
    return (
        <div>
            <h1>Contact Us</h1>
            <p>Feel free to reach out with any questions!</p>
            <Link href="/">Go back to Home</Link>
        </div>
    );
};

export default Contact;

Step 4: Update Your Navigation

To make it easier for users to navigate your application, it’s a good idea to add a navigation menu. You can create a reusable component for this. Create a new folder called components and a new file named Navbar.js:

mkdir components
touch components/Navbar.js

Add the following code to Navbar.js:

import Link from 'next/link';

const Navbar = () => {
    return (
        <nav>
            <Link href="/">Home</Link>
            <Link href="/about">About</Link>
            <Link href="/contact">Contact</Link>
        </nav>
    );
};

export default Navbar;

Import and use the Navbar component in your index.js, about.js, and contact.js files:

import Navbar from '../components/Navbar';

// Then include <Navbar /> at the top of your component

Optimizing and Troubleshooting

Code Optimization Tips

Static Generation: Use Next.js's static generation features for faster load times. Consider using getStaticProps for data-fetching when building your pages.
Image Optimization: Utilize Next.js’s built-in <Image /> component to automatically optimize images for faster loading.
CSS and Component Libraries: Leverage CSS modules or libraries like Tailwind CSS for styling.

Common Problems and Solutions

404 Errors: Ensure that your file names match the routes you are trying to access.
Broken Links: Always use the <Link> component from Next.js for internal navigation to maintain client-side navigation benefits.
Performance Issues: Monitor your application’s performance using tools like Lighthouse in Chrome DevTools.
