Nuxt 3 automatically imports components, composables, and utility functions, reducing the need for explicit imports throughout your application.
In the rest of the migration documentation, you will notice that key Nuxt and Vue utilities do not have explicit imports. This is not a typo; Nuxt will automatically import them for you, and you should get full type hinting if you have followed the instructions to use Nuxt’s TypeScript support.

​
How Auto-imports Work

Nuxt 3 will automatically import:
  • Components from the components/ directory
  • Composables from the composables/ directory
  • Vue APIs like ref, computed, watch, etc.
  • Nuxt utilities like navigateTo, useRoute, useRouter, etc.
This means you can use these in your components without explicit import statements: 
<template>
  <div>
    <MyComponent />
  </div>
</template>

<script setup>
// No imports needed!
const count = ref(0)
const route = useRoute()

function navigate() {
  navigateTo('/about')
}
</script>

​
Migration from @nuxt/components

If you have been using @nuxt/components in Nuxt 2, you can remove components: true in your nuxt.config. If you had a more complex setup, note that the component options have changed somewhat. See the components documentation for more information.
You can look at .nuxt/types/components.d.ts and .nuxt/types/imports.d.ts to see how Nuxt has resolved your components and composable auto-imports.

​
Benefits of Auto-imports

  1. Less boilerplate - No need to write import statements for commonly used utilities
  2. Better developer experience - Focus on your logic, not on managing imports
  3. Type safety - Full TypeScript support with auto-generated type definitions
  4. Tree-shaking - Only imported code is included in your bundle

​
Explicit Imports

If you prefer explicit imports, you can disable auto-imports in your nuxt.config: 
export default defineNuxtConfig({
  imports: {
    autoImport: false
  }
})
You can also selectively import from #imports: 
import { ref, computed } from '#imports'

​
Custom Auto-imports

You can configure custom auto-imports in your nuxt.config: 
export default defineNuxtConfig({
  imports: {
    dirs: [
      // Scan top-level modules
      'composables',
      // Scan nested directories
      'composables/*/index.{ts,js,mjs,mts}',
      // Scan all modules within given directory
      'composables/**'
    ]
  }
})

​
Debugging Auto-imports

To see what Nuxt has auto-imported, check these generated files:
  • .nuxt/types/components.d.ts - Auto-imported components
  • .nuxt/types/imports.d.ts - Auto-imported composables and utilities
These files are automatically updated when you add new components or composables to your project.
