Introduction
Built on Vue 3, Vite, and Nitro, Nuxt 3 enables SSR, SSG, API routes, and edge deployment. Convention over configuration: file-based routing, auto-imports, composables. Companies like GitLab, Upwork, and BMW use it in production. The Nitro server runs on Node.js, Deno, Bun, Cloudflare Workers, and Vercel Edge.
Why Nuxt 3
Built on Vue 3, Vite, and Nitro, Nuxt 3 enables SSR, SSG, API routes, and edge deployment. Convention over configuration: file-based routing, auto-imports, composables. Companies like GitLab, Upwork, and BMW use it in production. The Nitro server runs on Node.js, Deno, Bun, Cloudflare Workers, and Vercel Edge.
Auto-Imports and Composables
Vue APIs, Nuxt composables, and user-defined composables are auto-imported. useFetch wraps useAsyncData with SSR handling, caching, and refetching. Server routes in server/api/ create API endpoints with HTTP methods, path parameters, middleware, and error handling.
Nitro Server Engine
Universal server runtime across platforms. File-based routing, presets for 20+ platforms, storage abstraction (filesystem, Redis, S3), cache API, scheduled tasks, and WebSocket support. Build output is self-contained and optimized for the target platform.
Rendering Modes
SSR, SSG, ISR, and hybrid rendering per route. Route rules configure rendering per route in nuxt.config.ts. Public pages use SSR, dashboards use CSR, blog posts use ISR. The hybrid approach optimizes for each page's requirements.
Server Components and Edge
Server components render on server, sending only HTML to client, reducing JavaScript bundle. Edge deployment with minimal configuration. Storage abstraction mitigates edge limitations. Serverless deployment with AWS Lambda and other platforms.
Performance and Next.js Comparison
Built-in: code splitting, lazy loading, image optimization, font optimization, payload extraction, prefetching. Nuxt 3 vs Next.js: both offer SSR/SSG/ISR, API routes, edge deployment. Choice depends on Vue vs React preference. Both are excellent for full-stack development.
