nitro

Skill

Nitro is the framework-agnostic server toolkit (powering Nuxt) for building and deploying web servers anywhere. Use when working with nitro.config, server routes/event handlers, route rules, caching, storage, tasks, websockets, or deploying to Node/Bun/Deno/Cloudflare/Vercel.

The skill is based on Nitro v3 (beta), generated at 2026-06-22.
Nitro is a framework-agnostic, deployment-agnostic server toolkit powered by H3 v2, unstorage, and Vite/Rolldown/Rollup. It powers Nuxt and works standalone. From one codebase it builds optimized output for Node.js, Bun, Deno, Cloudflare, Vercel, Netlify, and more.
Key capabilities:
  • Filesystem routing with H3 v2 event handlers, dynamic params, and method suffixes.
  • Route rules for declarative caching, headers, redirects, proxying, and auth.
  • Caching layer (cached handlers/functions, SWR) on top of unstorage KV.
  • Runtime config overridable via NITRO_* env vars.
  • Tasks (on-demand + scheduled/cron), WebSockets/SSE, a SQL database layer, and OpenAPI auto-docs.
  • Plugins & lifecycle hooks, custom renderer/server entry, and portable deployment presets.
Nitro v3 renamed the package nitropack → nitro and adopts H3 v2 (web-standard Request/Response). If unsure about v2-vs-v3 APIs, read advanced-migration [blocked] first.
