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 4.x, generated at 2026-06-22.

Nuxt 4 note: 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 now point at app/; use ~~/@@ for the root.
