Nuxt 4+ Development
Progressive guidance for Nuxt 4+ projects (v4.3+) 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
- references/nuxt-performance.md - Performance optimization, lazy loading, profiling tools
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 ts-library skill
Loading Files
Consider loading these reference files based on your task:
- references/server.md - if creating API endpoints or server middleware
- references/routing.md - if setting up pages, layouts, or route groups
- references/nuxt-composables.md - if using Nuxt composables (useFetch, useRequestURL, etc.)
- references/middleware-plugins.md - if working with middleware or plugins
- references/nuxt-components.md - if using Nuxt components (NuxtLink, NuxtImg, etc.)
- references/nuxt-config.md - if editing nuxt.config.ts
- references/project-setup.md - if setting up CI/ESLint/build tools
- references/nuxt-performance.md - if optimizing performance, lazy loading, or profiling
DO NOT load all files at once. Load only what's relevant to your current task.
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.
