Don’t make the return type of useRouteLoaderData nullable if its argument is "root"

[lensbart]

If I’m not mistaken, the root route loader data is always available, because this route encapsulates all other routes.

It would be nice if useRouteLoaderData would be overloaded and would return SerializeFrom<typeof rootLoader> if its argument is "root", and SerializeFrom<typeof rootLoader> | undefined (as it currently does) otherwise.

I recommend creating a custom hook that you export from root

// root.tsx

export function useRootLoaderData() {
  return useLoaderData<typeof loader>()
}

Is this no different from

export const useRootLoaderData = () => {
  const [root] = useMatches();
  return root?.data as SerializeFrom<typeof loader>;
};
