本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。 提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。 MIT-0

契约

  1. minify CSS with lightningcss on a musl image with lifecycle scripts disabled, asserting the merged margin shorthand
  2. assert transform returns code as a Buffer that equals the expected string under == and in a template string but is never === it
  3. assert targets lower CSS nesting for Chrome 90 and leave the nested rule alone for Chrome 130
  4. assert targets are packed as major << 16, so a bare 130 means Chrome 0.0.130 and lowers everything
  5. assert @custom-media needs both drafts.customMedia and targets, and lowers to queries joined with or
  6. assert an undefined custom media reference throws SyntaxError with data.type CustomMediaNotDefined and a source location
  7. assert exactly one .node was dlopened and it is the musl platform package, read from the CJS module cache
  8. assert the image is musl, that the specifier the loader builds is lightningcss-linux-x64-musl, and that detect-libc is lightningcss's only runtime dependency
  9. assert from the installed loader's own source that it calls detect-libc familySync at require time, requires the platform package by name, and only then falls back to a .node in the package root
  10. assert both linux-x64 platform packages declare libc, musl and glibc respectively
  11. assert npm ci installed BOTH linux-x64 libc variants because the lockfile records os and cpu on every optional entry but never libc
  12. assert the image ships the npm 10 whose lockfile writer drops libc, since npm 12 records it and then installs only the musl package
  13. assert the unusable glibc binary is a full second copy of the 10 MB addon on disk
  14. assert from the ELF dynamic sections that the musl build needs libc.musl-x86_64.so.1 and the glibc build needs libc.so.6 and ld-linux-x86-64.so.2
  15. assert requiring the installed glibc binary fails with ERR_DLOPEN_FAILED naming the missing glibc loader
  16. assert a platform package that was never installed fails earlier, at resolution, with MODULE_NOT_FOUND
  17. assert the classic Cannot find module lightningcss.linux-x64-musl.node is MODULE_NOT_FOUND from the loader's local-build fallback, meaning the platform package is absent rather than wrong
