# Configuration

## Feature Flags

You can optionally disable some features from bridge or opt-in to less stable ones. In normal circumstances, it is always best to stick with defaults!

You can check [bridge/src/module.ts](https://github.com/nuxt/bridge/blob/main/packages/bridge/src/module.ts) for latest defaults.

```ts [nuxt.config.js|ts]
import { defineNuxtConfig } from '@nuxt/bridge'
export default defineNuxtConfig({
  bridge: {

    // -- Opt-in features --

    // Use Vite as the bundler instead of webpack 4
    // vite: true,

    // Enable Nuxt 3 compatible useHead
    // meta: true,

    // -- Default features --

    // Use legacy server instead of Nitro
    // nitro: false,

    // Disable Nuxt 3 compatible `nuxtApp` interface
    // app: false,

    // Disable Composition API support
    // capi: false,

    // ... or just disable legacy Composition API support
    // capi: {
    //   legacy: false
    // },

    // Do not transpile modules
    // transpile: false,

    // Disable <script setup> support
    // scriptSetup: false,

    // Disable composables auto importing
    // imports: false,

    // Do not warn about module incompatibilities
    // constraints: false
  },

  vite: {
    // Config for Vite
  }
})
```
