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/ or layouts/ → read routing.md
• Using useFetch, useRequestURL, navigation → read nuxt-composables.md
• Using <a>, <img>, <time> elements → read nuxt-components.md
• Working in middleware/ or plugins/ → 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.
