Next.js

About Next.js

Next.js is a React framework for building web applications, created by Vercel. It supports both server and client data fetching, server actions for running server-side code without a separate API layer, file-system-based routing with support for nested layouts, and React Server Components that render without shipping additional client-side JavaScript.

The framework includes CSS support through CSS Modules, Tailwind CSS, and other community libraries, route handlers for building API endpoints, and a proxy layer for defining routing and access rules such as authentication, experimentation, and internationalization. Rendering options include server and client rendering with per-page caching controls such as Incremental Static Regeneration. Next.js is built on React, and uses Turbopack, an incremental bundler written in Rust, along with the Speedy Web Compiler, a Rust-based platform for compilation and minification.

Next.js is intended for developers building full-stack web applications, from starter projects and ecommerce sites to blogs, SaaS products, multi-tenant applications, and realtime apps. It can be deployed to Vercel, and companies including Audible, Sonos, Dice, Notion, Product Hunt, Nike, and Washington Post are listed as users of the framework.
