feat(config): .ts/.js config self-compile loader#2113
Merged
Conversation
Closes #2100. Phase 1-1 of #2099. zts.config.{ts,mts,cts,mjs,js,cjs,json} 7종 확장자 로드 지원. - `.ts/.mts/.cts` 는 NAPI `transpile()` 로 self-compile 후 dynamic import - `.mjs/.js/.cjs` 는 직접 dynamic import (Bun/Node 표준) - `.json` 은 readFileSync + JSON.parse - tmp 파일은 config 옆에 작성해 user 의 node_modules resolution 보존 (esbuild `*.bundled-*.mjs` 패턴) - `.cts` 는 ZTS 가 CJS-only 로 취급해 ESM 구문을 거부하므로 파싱 단계에서만 `.ts` 로 가장 (에러 메시지에는 실제 경로 사용) 비범위: 자동 탐색 (#2102), BuildOptions 머지 (#2101), 함수형 config (#2103).

- existsSync precheck 제거 (TOCTOU 회피 + syscall 절감) — readFileSync /
import() 의 ENOENT 를 catch 해 동일 메시지 throw.
- 죽은 cache-bust query (`?t=${Date.now()}`) 제거 — Phase 1 scope 에서 같은
프로세스 다중 reload 가 없음. watch reload 는 #2107 에서 별도 처리.
- unlinkSync 실패 시 console.warn — silent swallow 방지.
- `.cts` parser 우회 주석에 `parser.zig` 위치 + `transpile()` follow-up
FIXME 추가.
- 테스트의 `resolveImportPath()` 헬퍼를 단일 호출 지점에 inline.
Part of #2099 / #2100.

zts.config.{ts,mts,cts,mjs,js,cjs,json}7종 확장자 로드..ts/.mts/.cts는 NAPItranspile()로 self-compile 후 dynamic import.node_modulesresolution 을 보존 (esbuild*.bundled-*.mjs패턴)..cts는 ZTS 가 CJS-only 로 취급하므로 파싱 단계에서만.ts로 가장 (에러 메시지에는 실제 경로 유지).비범위
