react-query ssr설정

react-query ssr 설정하기인데 어느 부분이 ssr 설정인지 잘모르겠습니다 어느부분인가요??

export async function getPostRecommends({ pageParam }: Props) {
  const res = await fetch(
    `http://localhost:9090/api/postRecommends?cursor=${pageParam}`,
    {
      next: {
        tags: ["posts", "recommends"],
      },
    }
  );
  // The return value is *not* serialized
  // You can return Date, Map, Set, etc.

  if (!res.ok) {
    // This will activate the closest `error.js` Error Boundary
    throw new Error("Failed to fetch data");
  }

  return res.json();
}
