This is a Stream that will strictly buffer when paused.
Connect it to anything you need buffered.
var ps = require('pause-stream')();
badlyBehavedStream.pipe(ps.pause())
aLittleLater(function (err, data) {
ps.pipe(createAnotherStream(data))
ps.resume()
})PauseStream will buffer whenever paused.
it will buffer when yau have called pause manually.
but also when it's downstream dest.write()===false.
it will attempt to drain the buffer when you call resume
or the downstream emits 'drain'
PauseStream is tested using stream-spec
and stream-tester
This is now the default case of through
