Pre-render one App Router route per locale with `generateStaticParams`. Locale routing and request locale resolution use the same setup as dynamic routes.

## Keep your Next.js config [#config]

Static generation does not change your `withGTConfig` setup:

```ts title="next.config.ts"
import type { NextConfig } from 'next';
import { withGTConfig } from 'gt-next/config';

const nextConfig: NextConfig = {};

export default withGTConfig(nextConfig);
```

## Configure locale routing [#routing]

Follow the [App Router middleware guide](/docs/react/nextjs/app-router-middleware) to create `proxy.ts`, move your routes under `app/[locale]`, and define the custom `getLocale` function.

## Disable region detection [#region]

The default region resolver reads a cookie, which makes the route dynamic. Add `getRegion.ts` at your project root to disable region detection during prerendering:

```ts title="./getRegion.ts"
export default async function getRegion() {
  return undefined;
}
```

`withGTConfig` detects this file automatically.

## Generate locale routes [#generate-routes]

Return one route parameter for every configured locale:

```tsx title="app/[locale]/page.tsx"
import { getLocales, T } from 'gt-next';

export function generateStaticParams() {
  return getLocales().map((locale) => ({ locale }));
}

export default function HomePage() {
  return <T>Welcome to our site</T>;
}
```

Next.js now pre-renders `app/[locale]/page.tsx` once for each locale.
