작업 요약
매치가 넘어갈 때마다 상품 이미지가 깜빡이던 문제 수정 — 기록 대기 중 스켈레톤 분기 제거 및 상품 이미지 프리로드 추가
원인
처음엔 이미지 로딩 지연으로 판단해 프리로드를 먼저 적용했습니다. 그러나 프리로드가 적용되어 전환 시점에
/_next/image요청이 0건인 상태에서도 깜빡임이 그대로 재현되었습니다. 이미지를 미리 모두 받아둬도 깜빡이므로 네트워크는 원인이 아니었습니다.실제 원인은 매치 기록 요청(
POST matches)이 66~197ms 만에 끝나는 그 짧은 대기 동안VsSection을MatchSkeleton으로 갈아끼우는 분기였습니다.작업 내용
1. 깜빡임 제거
isRecordingMatch·isNavigatingToResult도 함께 제거VsSection이 remount되지 않아 발생하지 않음MatchSkeleton은currentMatch가 없는 경우에 계속 사용2. 상품 이미지 프리로드
깜빡임의 원인은 아니었지만, 딥링크·새로고침으로 매치 화면에 바로 들어오는 경우를 위해 남겼습니다. 다음 대진은 기록 응답(
nextMatch)으로만 알 수 있어 미리 조회할 수 없지만, 후보 목록(remainingItems)은 이미 알고 있어서 그 이미지를 먼저 캐시에 올려둡니다.['tournament', id]를 읽기만 해 추가 API 요청 없음3. 캐시 키 맞춤
next/image는src를 그대로 쓰지 않고sizes·DPR로srcset후보를 골라/_next/image?url=...&w=640&q=75를 요청합니다. > 원본 URL로 프리로드하면 키가 어긋나 캐시 미스가 되고 트래픽만 두 배가 됨getImageProps로 렌더와 동일한srcSet/sizes를 뽑아 브라우저가 같은 후보를 고르게 처리sizes문자열은PRODUCT_CARD_IMAGE_SIZES상수로ProductCard와 공유해 값이 어긋날 수 없게 함loading·match두 라우트가 공유하므로tournament/[id]/_common/으로 이동스크린샷
