Learn NEXT-JS with Real Code Examples

Next.js helps developers build production-ready React applications with routing and rendering handled out of the box.

It provides hybrid rendering models like SSR, SSG, ISR, and RSC.

Next.js is optimized for performance, scalability, and full-stack React development.

Server Components by default

Dynamic and static routing

Layouts and nested routing

Next.js API routes for backend logic

Middleware for edge functions

Server vs Client components

Layouts and nested routes

Rendering models (SSR, SSG, ISR)

API routes and server actions

Image and font optimization

app/ - routing, pages, layouts

components/ - UI building blocks

public/ - static files

styles/ - global or module CSS

next.config.js - framework configuration

Create routes inside `app/` directory

Use components inside server or client boundaries

Fetch data using server components or APIs

Style using CSS modules, Tailwind, or styled-components

Build and deploy via Vercel or Node servers

Beginner: static pages

Intermediate: SSR pages + API routes
