[ann] pump - pipe streams together and destroy all them if one of the closes / emits an error

[Mathias Buus Madsen]

Usually when I pipe streams I want to destroy the source if the destination closes.

Since pipe does not do that I kept repeating this

source

.on('close', dest.destroy.bind(dest))

.on('error', dest.destroy.bind(dest))

.pipe(dest)

.on('close', source.destroy.bind(source))

.on('error', source.destroy.bind(source))

I decided to do a small module that does this for me. It is called pump

Using pump you can do the above like so

var pump = require('pump');

pump(source, transform1, transform2, ..., dest, function(err) {

console.log('pipe finished', err);

});

It works with both 0.8 and 0.10 streams.

Why do you have to bind it?
