Definition
Next.js is a React framework that adds server-side rendering (SSR), static site generation (SSG), API routes, and other production features to React. Created by Vercel, it solves common React challenges like SEO, performance, and routing. Next.js is ideal for content-heavy websites, e-commerce platforms, and applications where search engine visibility is critical.
Key Points
- Server-side rendering (SSR) and static site generation (SSG) for SEO
- Built-in API routes eliminate the need for a separate backend for simple APIs
- Image optimisation, font optimisation, and automatic code splitting
- Used by major companies: Hulu, TikTok, Notion, and many Indian startups

Frequently Asked Questions
Use Next.js when you need SEO (blog, marketing site, e-commerce), server-side rendering for faster initial loads, or built-in API routes. Stick with plain React (Vite) for internal dashboards, admin panels, or apps where SEO doesn't matter and you want a simpler setup.
Absolutely. Next.js with static generation can handle millions of page views via CDN (like Vercel or Cloudflare). For dynamic content, ISR (Incremental Static Regeneration) provides the best of both worlds — static performance with dynamic data freshness.
