# Nuxt Configuration file

Nuxt can be easily configured with a single `nuxt.config` file, which can have either a `.js`, `.ts` or `.mjs` extension.

```ts
import { defineNuxtConfig } from 'nuxt'

export default defineNuxtConfig({
  // My Nuxt config
})
```

To ensure your configuration is up to date, Nuxt will make a full restart when detecting changes in the main configuration file, the `.env`, `.nuxtignore` and `.nuxtrc` dotfiles.
