여기에 제공된 스크립트에서 영감을 받아 다음과 같은 구성 가능한 예제를 만들었습니다.
- 사용하도록 설정
yarn하거나npm
- 잠금 파일을 기반으로 사용할 명령을 결정하도록 설정할 수 있으므로 사용하도록 설정
yarn했지만 디렉토리에 해당 디렉토리에만 package-lock.json사용할 수 있습니다 npm(기본값은 true).
- 로깅 구성
- 다음을 사용하여 병렬로 설치 실행
cp.spawn
- 먼저 무엇을할지 볼 수 있도록 드라 이런을 할 수 있습니다.
- 함수로 실행하거나 env vars를 사용하여 자동 실행 가능
- 함수로 실행할 때 선택적으로 확인할 디렉토리 배열 제공
- 완료되면 해결되는 promise를 반환합니다.
- 필요한 경우 최대 깊이를 설정할 수 있습니다.
- 폴더를 찾으면 반복을 중지하는 것을 알고 있습니다.
yarn workspaces(구성 가능) 있습니다.
- 쉼표로 구분 된 env var를 사용하거나 config에 일치시킬 문자열 배열 또는 파일 이름, 파일 경로 및 fs.Dirent obj를 수신하고 부울 결과를 예상하는 함수를 전달하여 디렉토리를 건너 뛸 수 있습니다.
