A comprehensive guide to building web applications with Next.js

Getting Started with Next.js

Next.js is a powerful React framework that makes building web applications a breeze. In this guide, we'll explore the key features that make Next.js stand out.

Key Features

1. File-System Based Routing

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

// pages/about.js
export default function About() {
  return <h1>About Page</h1>
}

2. Server-Side Rendering (SSR)

Next.js supports multiple rendering strategies:

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

3. Static Site Generation (SSG)

// SSG Example
export async function getStaticProps() {
  const posts = await getPosts()
  
  return {
    props: {
      posts
    }
  }
}

Getting Started

  1. Create a new Next.js app:
npx create-next-app@latest my-app
  1. Start the development server:
cd my-app
npm run dev

Best Practices

  • Use the App Router for new projects
  • Implement proper error boundaries
  • Optimize images with next/image
  • Use proper TypeScript types
