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
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
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.
