Summary

  • --platform=react-native에서 IIFE 자동 적용 제거 (Rollipop/Metro 호환)
  • --platform=browser만 IIFE 유지

배경

Rollipop 번들은 IIFE 없이 글로벌 스코프에서 실행. ZTS는 isBrowserLike()에 react-native가 포함되어 IIFE가 자동 적용됨. RN에서는 preamble + __esm 래핑이 스코프 격리를 담당하므로 IIFE 불필요.

Test plan

  • zig build test — 전체 통과
  • bun test tests/bundle-smoke.test.ts tests/runtime-helpers.test.ts — 111개 통과
  • --platform=browser 여전히 IIFE 적용 확인
  • --platform=react-native IIFE 미적용 확인

fix(bundler): RN 플랫폼에서 IIFE 래핑 제거
5ba7496 
react-native는 IIFE 불필요 — Metro/Rollipop도 글로벌 스코프에서 실행.
preamble과 __esm 래핑이 스코프 격리를 담당.

기존: --platform=react-native → isBrowserLike()=true → IIFE 자동 적용
수정: --platform=browser만 IIFE 자동 적용, react-native는 ESM(default)
