Wrap safe-area colors in payload in the web sender.
If PR #57’s sender is served to this app, it posts { type, bottom, top }. dispatchBridgeMessage passes only payload to parseSafeAreaColorsPayload, which rejects the missing value. The handler then does not update the safe-area colors, so WebViewScreen keeps its defaults. Send the colors inside payload before deploying the sender with this receiver.

🎯 해결하려는 문제가 무엇인가요?
앱은 웹이
postMessage로 보내는 메시지를safeAreaColors하나만 받는데, JSON 파싱·type판별·검증·반영이safeAreaColors.ts와WebViewScreen.handleMessage에 1:1로 묶여 있다. 앞으로 인증 토큰·푸시 등 여러 영역에서 값을 받아오면handleMessage에if (parseA) … else if (parseB) …가 쌓인다.❓ 왜 해결해야 하나요?
두 번째 메시지가 들어오기 전에 수신 구조를 잡아 두면, 이후 메시지마다 "정의 파일 하나 + 레지스트리 한 줄 + 화면 핸들러 한 줄"로 끝난다. 나중에 정리하면 이미 쌓인 분기를 걷어내야 한다.
⭐ 어떻게 해결했나요?
{ type, payload }로 정했다.type은 메시지 표식,payload는 메시지별 본문src/features/webview/bridge/bridge.ts—parsers레지스트리 하나에서BridgeHandlers타입을 파생하고,dispatchBridgeMessage(data, handlers)가 파싱 →type조회 → 파서 검증 → 핸들러 호출을 맡는다safeAreaColors.ts를bridge/messages/로 옮기고, 파서 입력을 원문 string에서payload: unknown으로 바꿨다. 기본값·색 검증·"왜" 주석은 그대로WebViewScreen.handleMessage는dispatchBridgeMessage(event.nativeEvent.data, { safeAreaColors: setSafeAreaColors })한 줄이 됐다🧩 이 PR의 한계 & 트레이드오프
{ type, bottom, top })를 보낸다. 이 PR만 머지되면 세이프에어리어 색이 기본값으로 고정된다. 웹 PR #57에{ type, payload: { top, bottom } }반영을 요청했고, 두 PR을 맞춰 배포해야 한다. (현재 dev 배포에는 #57이 포함돼 있지 않아 과도기 호환 코드는 넣지 않았다)id/version/응답 같은 확장은 넣지 않았다. 필요해질 때 붙인다dispatchBridgeMessage안에 캐스팅이 하나 있다. 레지스트리 키로 좁힌type과 파서 결과의 상관관계를 TS가 인덱스 접근에서 추적하지 못해서다. 외부 시그니처(BridgeHandlers)는 정확히 잡혀 있어 사용처에는 새지 않는다⛓️ 기존 기능에 미치는 영향
WebViewScreen의 나머지는 손대지 않았다🔀 Edge Case & 실패 시나리오
dispatchBridgeMessage를 node로 직접 돌려 확인했다.{ type: "safeAreaColors", payload: { top, bottom } }정상typetype: "__proto__"Object.hasOwn으로 레지스트리 자기 키만 인정)null핸들러 키를 오타 내면(
safeAreaColor) 컴파일 에러가 나는 것도 확인했다.📋 검토한 대안과 선택 이유
type을 걷어내야 한다. 웹 PR이 아직 열려 있어 지금 바꾸는 게 가장 싸다고 봤다useWebViewBridge훅: 메시지가 하나인 지금은 과하다. 함수 하나로 충분하고 훅이 더 얹는 게 없어bridge.ts하나로 뒀다💬 리뷰 포인트
[r]봉투{ type, payload }형식 — 웹 PR #57과 맞춰야 하므로 이 결정에 이견이 있으면 먼저[c]bridge.ts의 타입 파생 방식과 마지막 캐스팅 주석이 납득되는지[a]bridge.ts상단의 메시지 추가 절차 주석이 충분한지 (별도 문서는 두지 않았다)Summary by CodeRabbit
