Possible to unpipe highland.js streams? #471

Hi,

Just curious, is it possible to .unpipe a highland.js stream? If yes, how should I do it? Thanks.

For example..

h().unpipe(stream)

I have two different streams, and I want to unpipe the writable from the readable stream without affecting the other streams still piped to the readable streams..

There is no unpipe method. You should transform the Highland stream into a node stream (by piping to PassThrough if you want to use node stream features that Highland doesn't provide.

// You may need to specify objectMode and/or highWaterMark depending on your use case.
var stream = h(...).pipe(new PassThrough());
stream.pipe(....);

// Later on.
stream.unpipe(...);
