fix(flow): component ref → React.forwardRef 래핑 by ohah · Pull Request #773 · ohah/zntc

ohah · 2026-04-05T18:32:37Z

Summary

Flow component View(ref?, ...props) 문법에서 ref를 props 안에 넣어서 React가 ref를 받지 못하는 버그 수정
hermes-parser와 동일하게 React.forwardRef + 2번째 인자로 ref 분리
RN View/Text 등 모든 component with ref 컴포넌트에 영향

변환 결과

// Before (잘못됨)
function View({ref, ...props}) { ... }  // ref가 props 안에 → React가 ref 전달 불가

// After (hermes-parser 호환)
function View_withRef({...props}, ref) { ... }  // ref가 2번째 인자
const View = React.forwardRef(View_withRef);

Flow의 `component View(ref?, ...props)` 문법에서 ref를 props의 일부로 취급하여 React가 View(props, ref)로 호출할 때 ref가 undefined가 되는 버그. hermes-parser와 동일하게 변환: - ref 있으면: function Name_withRef({...props}, ref) + const Name = React.forwardRef(Name_withRef) - ref 없으면: function Name({...props}) (기존 동작) - rest만 있으면: function Name(props) (destructuring 없이 단일 param) - 파서: ref 감지 시 flow_component_wrapper AST 노드 생성 - transformer: pending_nodes 패턴으로 1→2 statement 확장 - 테스트 3개 추가 (forwardRef, plain function, rest-only) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
