Getting Started with Next.js

Next.js is a React framework that enables server-side rendering and static site generation for React applications. It's designed to make building React applications easier and more efficient.

Why Next.js?

Next.js provides several key features that make it a popular choice for React developers:

• Server-side rendering (SSR): Renders pages on the server, improving performance and SEO.
• Static site generation (SSG): Pre-renders pages at build time for even better performance.
• File-based routing: Creates routes based on the file structure in the pages directory.
• API routes: Allows you to create API endpoints as part of your Next.js application.
• Built-in CSS and Sass support: Makes styling your application easier.

Creating Your First Next.js App

To create a new Next.js application, you can use the following command:

npx create-next-app my-next-app

This will create a new Next.js application in a directory called my-next-app. Once the installation is complete, you can navigate to the directory and start the development server:

cd my-next-app
npm run dev

Your Next.js application will now be running at http://localhost:3000.

Creating Pages

In Next.js, pages are React components exported from files in the pages directory. Each page is associated with a route based on its file name.

For example, to create a page at the route /about, you would create a file at pages/about.js:

export default function About() {
  return (
    <div>
      <h1>About Us</h1>
      <p>This is the about page of our Next.js application.</p>
    </div>
  );
}
