Merge multiple streams into a unified stream

npm install @sindresorhus/merge-streams

import mergeStreams from '@sindresorhus/merge-streams';

const stream = mergeStreams([streamA, streamB]);

for await (const chunk of stream) {
	console.log(chunk);
	//=> 'A1'
	//=> 'B1'
	//=> 'A2'
	//=> 'B2'
}

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, the stream remains open but can be manually ended.

Type: stream.Readable

A single stream combining the output of multiple streams.

Pipe a new readable stream.

Throws if MergedStream has already ended.

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

Returns false if the stream was not previously added, or if it was already removed by MergedStream.remove(stream).

The removed stream is not automatically ended.
