Siphon multiple event listeners to a single function.

Build Status

Installation

Works with Express 3.0.x

$ npm install siphon

Usage

Siphon will add a one time listener to each emitter in the emitter array

// require it
var siphon = require('siphon'),
    EventEmitter = require('events').EventEmitter
    emitter1 = new EventEmitter(),
    emitter2 = new EventEmitter();

// siphon an event
siphon('init', [emitter1, emitter2], function (emitter1Args, emitter2Args) {
  console.log('Both emitters have fired!');
  console.log(emitter1Args[0] === emitter1);
  console.log(emitter2Args[0] === emitter2);
});

// Fire the events
console.log('Firing emitter 1');
emitter1.emit('init', emitter1);
console.log('Firing emitter 2');
emitter2.emit('init', emitter2);
