Nuxt 4+ Development
Progressive guidance for Nuxt 4+ projects with latest patterns and conventions.
When to Use
Working with:
- Server routes (API endpoints, server middleware, server utils)
- File-based routing (pages, layouts, route groups)
- Nuxt middleware (route guards, navigation)
- Nuxt plugins (app extensions)
- Nuxt-specific features (auto-imports, layers, modules)
Available Guidance
Read specific files based on current work:
- references/server.md - API routes, server middleware, validation (Zod), WebSocket, SSE
- references/routing.md - File-based routing, route groups, typed router, definePage
- references/middleware-plugins.md - Route middleware, plugins, app lifecycle
- references/nuxt-composables.md - Nuxt composables (useRequestURL, useFetch, navigation)
- references/nuxt-components.md - NuxtLink, NuxtImg, NuxtTime (prefer over HTML elements)
- references/nuxt-config.md - Configuration, modules, auto-imports, layers
For Vue composables: See vue skill composables.md (VueUse, Composition API patterns) For UI components: use nuxt-ui skill For database/storage: use nuxthub skill For content-driven sites: use nuxt-content skill For creating modules: use nuxt-modules skill For project scaffolding/CI: use personal-ts-setup skill
Usage Pattern
Progressive loading - only read what you need:
- Creating API endpoint? → references/server.md
- Setting up pages/routing? → references/routing.md
- Using composables/data fetching? → references/nuxt-composables.md
- Adding middleware/plugins? → references/middleware-plugins.md
- Configuring Nuxt? → references/nuxt-config.md
- Setting up CI/ESLint? → references/project-setup.md
DO NOT read all files at once. Load based on context:
- Working in
server/→ read server.md - Working in
pages/orlayouts/→ read routing.md - Using
useFetch,useRequestURL, navigation → read nuxt-composables.md - Using
<a>,<img>,<time>elements → read nuxt-components.md - Working in
middleware/orplugins/→ read middleware-plugins.md - Editing
nuxt.config.ts→ read nuxt-config.md
Nuxt 4 vs Older Versions
You are working with Nuxt 4+. Key differences:
| Old (Nuxt 2/3) | New (Nuxt 4) |
|---|---|
<Nuxt /> | <NuxtPage /> |
context.params | getRouterParam(event, 'name') |
window.origin | useRequestURL().origin |
| String routes | Typed router with route names |
| Separate layouts/ | Parent routes with <slot> |
If you're unsure about Nuxt 4 patterns, read the relevant guidance file first.
