# pump
|
|
|
|
pump is a small node module that pipes streams together and destroys all of them if one of them closes.
|
|
|
|
```
|
|
npm install pump
|
|
```
|
|

|
|
## What problem does it solve?
|
|
|
|
When using standard `source.pipe(dest)` source will _not_ be destroyed if dest emits close or an error.
|
|
You are also not able to provide a callback to tell when then pipe has finished.
|
|
|
|
pump does these two things for you
|
|
|
|
## Usage
|
|
|
|
Simply pass the streams you want to pipe together to pump and add an optional callback
|
|
|
|
``` js
|
|
var pump = require('pump')
|
|
var fs = require('fs')
|
|
|
|
var source = fs.createReadStream('/dev/random')
|
|
var dest = fs.createWriteStream('/dev/null')
|
|
|
|
pump(source, dest, function(err) {
|
|
console.log('pipe finished', err)
|
|
})
|
|
|
|
setTimeout(function() {
|
|
dest.destroy() // when dest is closed pump will destroy source
|
|
}, 1000)
|
|
```
|
|
|
|
You can use pump to pipe more than two streams together as well
|
|
|
|
``` js
|
|
var transform = someTransformStream()
|
|
|
|
pump(source, transform, anotherTransform, dest, function(err) {
|
|
console.log('pipe finished', err)
|
|
})
|
|
```
|
|
|
|
If `source`, `transform`, `anotherTransform` or `dest` closes all of them will be destroyed.
|
|
|
|
Similarly to `stream.pipe()`, `pump()` returns the last stream passed in, so you can do:
|
|
|
|
```
|
|
return pump(s1, s2) // returns s2
|
|
```
|
|
|
|
If you want to return a stream that combines *both* s1 and s2 to a single stream use
|
|
[pumpify](https://github.com/mafintosh/pumpify) instead.
