Summary

  • loader=.none인 파일(예: .png)이 resolve되면 require_xxx() 리라이트만 생성되고 모듈 코드가 번들에 누락되어 런타임 ReferenceError 발생하던 버그 수정
  • no_loader 에러 코드 추가로 esbuild 호환 진단 메시지 제공
  • --platform=react-native 시 Metro assetExts 호환 확장자(이미지/폰트/미디어 19개)에 file 로더 기본 할당 (사용자 --loader 오버라이드 우선)

Test plan

  • 유닛 테스트: no-loader 에러 발생 확인
  • 유닛 테스트: --loader:.png=file 시 정상 번들 확인
  • 통합 테스트: CLI no-loader 에러 메시지 확인
  • 통합 테스트: --loader:.png=file CLI 성공
  • 통합 테스트: --platform=react-native 자동 처리
  • 통합 테스트: 사용자 --loader:.png=dataurl 우선 확인
  • 기존 RN 통합 테스트 (es5-rn) 17개 통과

fix(bundler): loader 미설정 에셋 파일 silent failure → 빌드 에러 + RN 프리셋 기본 로더
6023791 
loader=.none인 파일(예: .png)이 resolve되면 require_xxx() 리라이트는 생성되지만
실제 모듈 코드가 번들에 포함되지 않아 런타임 ReferenceError가 발생하던 버그 수정.

- no_loader 에러 코드 추가 (esbuild 호환 진단)
- --platform=react-native 시 Metro assetExts 호환 확장자에 file 로더 기본 할당
  (이미지/폰트/미디어 19개, 사용자 --loader 오버라이드 우선)
- 유닛 테스트 2개 + 통합 테스트 4개 추가

fix(bundler): 플러그인 load 훅이 에셋 모듈을 오버라이드할 수 있도록 수정
ac395a2 
플러그인이 에셋 파일(.png 등)에 대해 소스를 반환해도 parseAssetModule이
덮어쓰는 버그 수정. 플러그인이 소스를 반환하면:
- module.loader를 .javascript로 변경하여 에셋 경로 스킵
- parseAssetModule은 module.source.len == 0일 때만 실행
