If your deployment platform supports splitting your app into multiple functions,
you should run this in a middleware that runs before the main handler
to reroute the request to the correct function and [generate a server-side manifest](/docs/kit/@sveltejs-kit#Builder)
with the `rerouteMiddleware` option set to `true`.

```js
// @errors: 7031
import { applyReroute } from '@sveltejs/kit/adapter';
// replace __HOOKS__ with the path to the reroute hook obtained from `builder.getReroutePath()`
import { reroute } from '__HOOKS__';

export default function middleware(request) {
	return applyReroute(request.url, reroute);
}
```

<div class="ts-block">

```dts
function applyReroute(
	url: string,
	reroute: import('@sveltejs/kit').Reroute
): Promise<URL>;
```

</div>
