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().
