Next.js is one of the most powerful and popular frameworks built on top of React. It helps developers create fast, scalable, and SEO-friendly web applications with ease. If you already know React or are planning to learn modern web development, learning Next.js is a smart career move.

In this guide, you’ll learn what Next.js is, why it’s important, its core features, and how to get started.

What is Next.js?

Next.js is an open-source React framework developed by Vercel. It enables developers to build server-side rendered (SSR), static site generated (SSG), and full-stack web applications using React.

Unlike a standard React app, Next.js comes with many built-in features such as routing, image optimization, API routes, and SEO support—without extra configuration.

Why Learn Next.js?

Learning Next.js offers several advantages over plain React:

  • Better SEO – Supports server-side rendering and static generation

  • High Performance – Faster page loads with optimized rendering

  • Easy Routing – File-based routing system

  • Full-Stack Capability – Create backend APIs using API routes

  • Production Ready – Used by companies like Netflix, TikTok, and GitHub

Key Features of Next.js

1. Server-Side Rendering (SSR)

Next.js can render pages on the server before sending them to the browser, improving SEO and performance.

2. Static Site Generation (SSG)

Pages can be generated at build time, making them extremely fast and secure.

3. File-Based Routing

Create pages simply by adding files to the pages or app directory—no routing libraries required.

4. API Routes
