# 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](references/server.md)** - API routes, server middleware, validation (Zod), WebSocket, SSE
- **[references/routing.md](references/routing.md)** - File-based routing, route groups, typed router, definePage
- **[references/middleware-plugins.md](references/middleware-plugins.md)** - Route middleware, plugins, app lifecycle
- **[references/nuxt-composables.md](references/nuxt-composables.md)** - Nuxt composables (useRequestURL, useFetch, navigation)
- **[references/nuxt-components.md](references/nuxt-components.md)** - NuxtLink, NuxtImg, NuxtTime (prefer over HTML elements)
- **[references/nuxt-config.md](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](references/server.md)
- Setting up pages/routing? → [references/routing.md](references/routing.md)
- Using composables/data fetching? → [references/nuxt-composables.md](references/nuxt-composables.md)
- Adding middleware/plugins? → [references/middleware-plugins.md](references/middleware-plugins.md)
- Configuring Nuxt? → [references/nuxt-config.md](references/nuxt-config.md)
- Setting up CI/ESLint? → [references/project-setup.md](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)                    |
| ----------------- | ------------------------------- |
| `index.vue`       | `(descriptive-name).vue`        |
| `<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.**
