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。

契约
- isStream returns true for Node.js Stream instances and objects with a pipe method, and false for primitives and plain objects
- isStream.readable returns true for readable streams including Readable, Duplex, and Transform, and false for purely Writable streams or non-streams
- isStream.writable returns true for writable streams including Writable, Duplex, and Transform, and false for purely Readable streams or non-streams
- isStream.duplex returns true for streams that are both readable and writable such as Duplex and Transform, and false for purely Readable or Writable streams
- isStream.transform returns true for Transform and PassThrough streams, and false for standard Duplex, Readable, or Writable streams
