@devtea2026/temporibus-totam-a-accusantium

@devtea2026/temporibus-totam-a-accusantium is a small node module that pipes streams together and destroys all of them if one of them closes.

npm install @devtea2026/temporibus-totam-a-accusantium

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.

@devtea2026/temporibus-totam-a-accusantium does these two things for you

Usage

Simply pass the streams you want to pipe together to @devtea2026/temporibus-totam-a-accusantium and add an optional callback

var @devtea2026/temporibus-totam-a-accusantium = require('@devtea2026/temporibus-totam-a-accusantium')
var fs = require('fs')

var source = fs.createReadStream('/dev/random')
var dest = fs.createWriteStream('/dev/null')

@devtea2026/temporibus-totam-a-accusantium(source, dest, function(err) {
  console.log('pipe finished', err)
})

setTimeout(function() {
  dest.destroy() // when dest is closed @devtea2026/temporibus-totam-a-accusantium will destroy source
}, 1000)

You can use @devtea2026/temporibus-totam-a-accusantium to pipe more than two streams together as well

var transform = someTransformStream()

@devtea2026/temporibus-totam-a-accusantium(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(), @devtea2026/temporibus-totam-a-accusantium() returns the last stream passed in, so you can do:

return @devtea2026/temporibus-totam-a-accusantium(s1, s2) // returns s2

Note that @devtea2026/temporibus-totam-a-accusantium attaches error handlers to the streams to do internal error handling, so if s2 emits an error in the above scenario, it will not trigger a proccess.on('uncaughtException') if you do not listen for it.

If you want to return a stream that combines both s1 and s2 to a single stream use @devtea2026/temporibus-totam-a-accusantiumify instead.
