Getting Started with Next.js: A Complete Guide for Beginners

Next.js has revolutionized the way we build React applications. As a student learning web development at KV AFS Bareilly, I've found Next.js to be one of the most powerful and beginner-friendly frameworks for creating modern web applications.

What is Next.js?

Next.js is a React framework that provides a complete solution for building production-ready web applications. It offers features like server-side rendering (SSR), static site generation (SSG), and automatic code splitting out of the box.

Key Features of Next.js

1. File-based Routing

Next.js uses a file-based routing system. Simply create a file in the pages directory, and it automatically becomes a route:

// pages/about.js
export default function About() {
  return 
About Page
}
// This creates the route /about

2. Server-Side Rendering (SSR)

Next.js can render pages on the server, improving SEO and initial page load times:

export async function getServerSideProps() {
  const data = await fetch('https://api.example.com/data')
  return {
    props: { data }
  }
}

3. Static Site Generation (SSG)

Generate static HTML at build time for better performance:

export async function getStaticProps() {
  return {
    props: { message: 'Hello from static generation!' }
  }
}

4. API Routes

Create backend API endpoints in the same project:

// pages/api/hello.js
export default function handler(req, res) {
  res.status(200).json({ message: 'Hello from API!' })
}
