Nuxt is a full-stack Vue framework that provides server-side rendering, file-based routing, auto-imports, and a powerful module system. It uses Nitro as its server engine for universal deployment across Node.js, serverless, and edge platforms.
The skill is based on Nuxt 5.x (5.0.0-0), generated at 2026-09-25.
Directory layout: the default srcDir is app/ — Vue app code (app.vue, components/, composables/, pages/, etc.) lives under app/, while server/, shared/, public/, modules/, layers/ and nuxt.config.ts stay at the project root. The ~/@ aliases point at app/; use ~~/@@ for the root.
Nuxt 5 note: Nuxt 5 makes many former experimental flags the default. The biggest shifts for agents: server code moves to Nitro v3 (h3 v2, Web-standard Request/Response), server utilities import from **nuxt/server** and are no longer auto-imported by default, $fetch/useFetch are typed from generated route types, routing is case-sensitive and typed by default, and the bundler is Vite 8 (Rolldown). Nuxt 5 requires Node 22.19/24.11+. A Nitro v2 compatibility layer (nitroLegacy) keeps older server code building during migration. See individual references for details.
