Getting Started with Next.js

2023-04-15

Next.js is a powerful React framework that makes it easy to build server-side rendered and statically generated web applications. In this post, we'll explore the basics of Next.js and how to get started with your first project.

Why Next.js?

Next.js offers several benefits over traditional React applications:

  • Server-side rendering for improved performance and SEO
  • Automatic code splitting for faster page loads
  • Simple page-based routing
  • API routes for building backend functionality
  • Built-in CSS support for easy styling
  • Static site generation for blazing-fast websites

Setting Up Your First Next.js Project

To get started with Next.js, follow these steps:

  1. Ensure you have Node.js installed on your machine
  2. Open your terminal and run the following command:
npx create-next-app@latest my-next-app

This will create a new Next.js project with a basic structure and configuration.

Project Structure

After creating your project, you'll see the following folder structure:


my-next-app/
  ├── pages/
  ├── public/
  ├── styles/
  ├── package.json
  └── next.config.js

The pages directory is where you'll create your application's routes and React components.

Creating Your First Page

To create a new page, simply add a new file to the pages directory. For example, create a file called about.js with the following content:


export default function About() {
  return (
    <div>
      <h1>About Us</h1>
      <p>Welcome to our Next.js website!</p>
    </div>
  )
}

Now you can access this page at http://localhost:3000/about.
