export default function PostPage({
  params,
}: {
  params: Promise<{ threadId: string }>;
}) {
  const { threadId } = use(params);

  const queryClient = getQueryClient();

  void queryClient.prefetchQuery(threadOptions(threadId));

  return (
    <HydrationBoundary state={dehydrate(queryClient)}>
      <Content id={threadId} />
    </HydrationBoundary>
  );
}
