流的类型

¥Types of streams

Node.js 中有四种基本的流类型：

¥There are four fundamental stream types within Node.js:

• Writable：可以写入数据的流（例如，fs.createWriteStream()）。

  ¥Writable: streams to which data can be written (for example, fs.createWriteStream()).

• Readable：可以从中读取数据的流（例如，fs.createReadStream()）。

  ¥Readable: streams from which data can be read (for example, fs.createReadStream()).

• Duplex：Readable 和 Writable 的流（例如，net.Socket）。

  ¥Duplex: streams that are both Readable and Writable (for example, net.Socket).

• Transform：可以在写入和读取数据时修改或转换数据的 Duplex 流（例如，zlib.createDeflate()）。

  ¥Transform: Duplex streams that can modify or transform the data as it is written and read (for example, zlib.createDeflate()).

此外，此模块还包括实用函数 stream.duplexPair()、stream.pipeline()、stream.finished() stream.Readable.from() 和 stream.addAbortSignal()。

¥Additionally, this module includes the utility functions stream.duplexPair(), stream.pipeline(), stream.finished() stream.Readable.from(), and stream.addAbortSignal().
