# PauseStream
|
|
|
|
This is a `Stream` that will strictly buffer when paused.
|
|
Connect it to anything you need buffered.
|
|
|
|
``` js
|
|
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](https://github.com/dominictarr/stream-spec)
|
|
and [stream-tester](https://github.com/dominictarr/stream-tester)
