Getting Started with Next.js
Next.js is an open-source React framework created by Vercel that enables developers to build high-performance, full-stack web applications.
As of March 2026, it is one of the most popular tools for production-grade React development, known for its "zero-config" approach to features like routing, rendering, and optimization.
Stable Release: Next.js 16.1.7 (released March 16, 2026).
Major Update: Next.js 16 (released October 21, 2025) introduced Turbopack as the default stable bundler, offering 5-10x faster refresh and significantly quicker production builds.
Core Concepts & Features
- App Router: The modern standard for routing in Next.js, supporting nested layouts, streaming, and React Server Components (RSC).
- Rendering Strategies:
- Server-Side Rendering (SSR): Generates HTML on the server for every request, ideal for dynamic or personalized content.
- Static Site Generation (SSG): Pre-builds pages into static HTML at build time for maximum speed.
- Incremental Static Regeneration (ISR): Updates static content after the site is live without requiring a full rebuild.
- Cache Components: Introduced in version 16, the
"use cache"directive provides explicit, granular control over caching logic, replacing the experimental Partial Prerendering (PPR). - Full-Stack Capabilities: Built-in Server Actions allow you to write backend logic (like database queries) directly inside your React components without creating separate API endpoints.
