title: preferredRegion Deprecated
---

## Why This Warning Occurred

One or more routes in your application use `export const preferredRegion`, which is deprecated.

## How to Migrate

Remove the `preferredRegion` export from your route files:

```diff
- export const preferredRegion = 'home'
```

This applies to all route files that support the `preferredRegion` segment config: `page.ts`, `layout.ts`, and `route.ts`.
