What is Next.js?

Next.js is a powerful and popular JavaScript framework that makes it easy to build modern web applications. It is based on React and offers a wide range of features for server-side rendering, routing, and more. Let's get started!

Setting Up Your Development Environment

Before you dive into Next.js, ensure you have the following prerequisites installed:

• Node.js
• npm (Node Package Manager)

Once you have these tools, you can create a new Next.js project using the following commands:

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

This will set up a new Next.js project named "my-next-app" for you.

Creating Your First Page

Next.js uses a file-based routing system, which means that each page is represented by a corresponding file in the "pages" directory. To create your first page, make a new file in the "pages" directory with a .js extension.

// pages/index.js
import React from 'react';
function HomePage() {
    return (
        <div>
            <h1>Welcome to Next.js!</h1>
            <p>This is your first Next.js page.</p>
        </div>
    );
}
export default HomePage;
                

Your new page is now accessible at / or /index in your Next.js application.

Running Your Next.js App

To start the development server and see your app in action, run the following command:

npm run dev
                

Your Next.js app will be available at http://localhost:3000. You can start building and testing your application locally.
