通过调用Readable streams的.pipe()方法可以把Readable streams的数据写入一个Writable , Transform, 或者Duplex stream。 readableStream.pipe( dst ) 1. 1>、创建 readable stream 这里我们创建一个readable stream! var Readable = require('stream').Readable; var rs = new Readable; rs.push('beep '); rs....

Interactive API reference for the JavaScript ReadableStream Object. Represents a readable stream of data. The stream can be read using the ReadableStreamReader or by piping to a WritableStream.

The ReadableStreamDefaultReader object, obtained from Response.body.getReader(), is used to read the stream incrementally; The TextDecoder.decode() method is called on the value property of the chunk to decode it into a string, and the resulting chunk is pushed into the "chunks" array; The re...

提案的API是基于Promise的,并尽可能的复用了现有的标准。例如ReadableStream和WritableStream用于socket的读写端。这使得我们可以很轻松地将数据从TCP Socket传输到接受ReadableStream作为输入的任何其他库或现有代码,或者通过WritableStream写入TCP Socket。 API的入口点是connect函数,它接受一个包含主机名和端口(以冒号分隔)的...
