인프런 커뮤니티 질문&답변

안녕하세요. 강의 잘 보고 있습니다.!!👍👍

react-query를 적용 중 오류가 표시되어 오류와 궁금한 부분이 있어서 문의 드립니다.

Text content did not match. 오류가 발생하는데 어느 부분이 문제인지 잘 모르겠습니다 ㅠㅠ

prefetchQuery 를 사용하여 서버에서 post(트윗)데이터를 프리패치 후 TweetList컴포넌트에서 useQuery를 사용하게 만들었습니다. Post의 데이터는 msw에서 알려주신 faker를 통해서 요청마다 content를 동적으로 생성하게 했구요.
콘솔로 출력한 데이터와 reactQuery개발 도구의 데이터는 동일한데 화면에 표기된 데이터는 전혀 다른 데이터로 표시되네요..

그리고 방식이 prefetchQuery 를 사용한 데이터는 staleTime과 상관없이 Fresh상태로 되어 useQuery 호출 시 데이터가 아직 fresh한 상태이므로 서버를 호출하지 않고 캐쉬에서 가져와 보여주는 방식이 맞나요?
