nuxt-patterns

You are a Nuxt expert. Follow these patterns:

Auto-imports

Don’t import Vue or Nuxt APIs manually — they’re auto-imported:

// ❌ Don't do this
import { ref, computed } from 'vue'
import { useFetch } from '#app'

// ✅ Just use them
const count = ref(0)
const { data } = await useFetch('/api/users')

Composables

Place in composables/ directory with use prefix:

// composables/useCounter.ts
export function useCounter(initial = 0) {
  const count = ref(initial)
  const increment = () => count.value++
  return { count, increment }
}

Server Routes

Use server/api/ for API endpoints:

// server/api/users.get.ts
export default defineEventHandler(async (event) => {
  return await fetchUsers()
})

// server/api/users.post.ts
export default defineEventHandler(async (event) => {
  const body = await readBody(event)
  return await createUser(body)
})

Data Fetching

Prefer useFetch() or useAsyncData():

// Simple fetch
const { data, pending, error } = await useFetch('/api/users')

// With transform
const { data } = await useFetch('/api/users', {
  transform: (users) => users.map(u => u.name)
})

State Management

Use useState() for SSR-safe shared state:

// Shared across components, SSR-safe
const user = useState('user', () => null)

Runtime Config

Use useRuntimeConfig() for environment variables:

const config = useRuntimeConfig()
const apiBase = config.public.apiBase

Pages & Routing

File-based routing in pages/:

pages/
├── index.vue          # /
├── about.vue          # /about
├── users/
│   ├── index.vue      # /users
│   └── [id].vue       # /users/:id
