API

mergeStreams(streams: stream.Readable[]): MergedStream

Merges an array of readable streams and returns a new readable stream that emits data from the individual streams as it arrives.

If you provide an empty array, it returns an already-ended stream.

MergedStream

Type: stream.Readable

A single stream combining the output of multiple streams.

MergedStream.add(stream: stream.Readable): void

Pipe a new readable stream.

Throws if MergedStream has already ended.

MergedStream.remove(stream: stream.Readable): void

Unpipe a stream previously added using either mergeStreams(streams) or MergedStream.add(stream).

The removed stream is not automatically ended.
