Next.js is a full-stack React framework by Vercel that adds server-side rendering, static generation, API routes, and file-based routing to React. It's the recommended way to build React applications for production, used by companies like TikTok, Notion, and Hulu.

How Next.js Works

Next.js solves React's pain points: SSR for SEO, file-based routing (no React Router config), API routes for backend logic, image optimization, and automatic code splitting. The App Router (Next.js 13+) uses React Server Components for better performance.

Deployment is seamless on Vercel but works anywhere — Docker, AWS, Cloudflare. The framework handles the complexity of modern web apps: streaming SSR, static/dynamic rendering decisions, middleware, and ISR (incremental static regeneration).

Why Developers Use Next.js

Next.js is the default choice for React applications that need SEO, performance, or full-stack capabilities. It's used by startups, enterprises, and everything in between. If you're building a React app for production, use Next.js.

Key Concepts

  • App Router — File-system based routing with layouts, loading states, and error boundaries — the modern Next.js approach
  • Server Components — Components that render on the server by default — smaller client bundles and better performance
  • API Routes — Backend endpoints in your Next.js project — handle form submissions, database queries, and webhooks
  • Static/Dynamic Rendering — Next.js automatically chooses between static (build-time) and dynamic (request-time) rendering per page

Frequently Asked Questions

Do I need Next.js for React?

Not for all projects. Simple SPAs work fine with Vite + React Router. But for production apps needing SEO, SSR, or full-stack features, Next.js saves enormous amounts of configuration and code.

Is Next.js only for Vercel?

No. Next.js deploys to any Node.js environment — Docker, AWS, Cloudflare, Railway, self-hosted. Vercel provides the best experience but isn't required.
