description: Opt-out specific dependencies from the Server Components bundling and use native Node.js `require`.
---

Dependencies used inside [Server Components](/docs/app/getting-started/server-and-client-components) and [Route Handlers](/docs/app/api-reference/file-conventions/route) will automatically be bundled by Next.js.

If a dependency is using Node.js specific features, you can choose to opt-out specific dependencies from the Server Components bundling and use native Node.js `require`.

```js filename="next.config.js"
/** @type {import('next').NextConfig} */
const nextConfig = {
  serverExternalPackages: ['@acme/ui'],
}

module.exports = nextConfig
```

Next.js includes a [short list of popular packages](https://github.com/vercel/next.js/blob/canary/packages/next/src/lib/server-external-packages.json) that currently are working on compatibility and automatically opt-ed out:
