Next.Js Overview
Next. js is a fast, scalable, and feature-rich open source framework, built on React. It also builds on top of React to provide server-side rendering (SSR), static-site generation (SSG), API routes, and automatic, no-hand-roll routing, meaning it's a fantastic choice for both front-end and full-stack development.
- File-based Routing: Turn on the creation of pages by PRIOR to adding. js or. tsx in the pages/ directory.
- Static Generation (SSG): Generates the static HTML at build time.
- Server-side Rendering (SSR): Renders pages on every request.
- API Routes: Create backend endpoints directly in the pages/api/ folder.
- Image Optimization: next/image provides image resizing on the fly, and has lazy loading built in.
- Built-in CSS and Sass support: Along with CSS-in-JS libraries including Tailwind CSS and styled-components.
- Dynamic Routing: Generate dynamic pages such as /blog/[slug]. js.
- Incremental Static Regeneration or ISR Entrepreneur and independent consultant Serving various enterprise technologies and frameworks: Update static content without re-generating the entire site.
- Middleware & Edge Functions: Run code at the edge before a request is finished - useful for authentication and redirects, etc.
App Router (New in Next. js 13+)
Uses app/ instead of pages/. Supports layouts, streaming, React Server Components (RSC). Better Support for nested routing.
