Overview

Next.js is a React full-stack framework developed by Vercel, headquartered in the United States, and one of the most popular React meta-frameworks. Next.js supports multiple rendering modes: client-side rendering (CSR), server-side rendering (SSR), static site generation (SSG), and incremental static regeneration (ISR). App Router is the new routing system built on React Server Components, with built-in API routes, image optimization, font optimization, middleware, and internationalization. This page belongs to the automation tool providers category.
