description: Opt-out specific dependencies from the dependency bundling enabled by `bundlePagesRouterDependencies`.
---

Opt-out specific dependencies from being included in the automatic bundling of the [`bundlePagesRouterDependencies`](/docs/pages/api-reference/config/next-config-js/bundlePagesRouterDependencies) option.

These pages will then use native Node.js `require` to resolve the dependency.

```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.jsonc) that currently are working on compatibility and automatically opt-ed out:
