将文件管道传输到不同的流

不确定这是否是最佳解决方案,但这对我很有效:

var GrowingFile = require('growing-file')
var unpipe = require('unpipe');
var audio = GrowingFile.open('test.wav')
audio.pipe(<some writable stream>);

//later in code
unpipe(audio);
audio.pipe(<some new writable stream>);

看见 readable.unpipe([destination])

var GrowingFile = require('growing-file')
var audio = GrowingFile.open('test.wav')
var writeableStream = <some writable stream>
audio.pipe(writeableStream);

setTimeout(() => {
  audio.unpipe(writeableStream)
  writeableStream = <some other writable stream>
  audio.pipe(writeableStream)
}, 60000)
