이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다. 통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다. MIT-0

컨트랙트

  1. assert browserslistToTargets encodes Safari 12 as the packed target value 12 shifted by 16 bits
  2. assert transformStyleAttribute returns a Buffer containing declarations without selector braces
  3. assert minification merges four margin declarations, reduces rgb red to its keyword, and adds the Safari webkit user-select prefix while retaining the standard declaration
