# stream-exhaust
|
||
|
|
|
||
|
|
Ensure that the provided stream is flowing data, even if the stream hasn't been
|
||
|
|
piped to another stream.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var exhaustively = require('stream-exhaust');
|
||
|
|
|
||
|
|
exhaustively(fs.createReadStream(__filename))
|
||
|
|
.on('close', () => { console.log('all done, despite being streams{1+N}!') });
|
||
|
|
```
|
||
|
|
|
||
|
|
## Prior Art
|
||
|
|
|
||
|
|
This is based on [stream-consume](https://github.com/aroneous/stream-consume)
|
||
|
|
by [aroneous](https://github.com/aroneous). It is a separate package because it has
|
||
|
|
different semantics:
|
||
|
|
|
||
|
|
1. It does not call `.resume()` on streams2+ streams. streams2 streams monkeypatch `.pipe`
|
||
|
|
when entering flowing mode; avoiding `resume()` avoids that fate.
|
||
|
|
2. It does not examine `._readableState`; instead it checks for the presence of `._read`.
|
||
|
|
|
||

## API
|
||
|
|
|
||
|
|
### exhaust(Stream s) -> Stream s
|
||
|
|
|
||
|
|
Takes a stream, `s`, and returns it. Ensures that the stream is flowing, either by calling
|
||
|
|
`.resume()` if the stream is a streams1 stream, or by piping it to a "black hole" stream that
|
||
|
|
continually asks for more data.
