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/ :
