voltrevo-event-emitter

My utopian vision for simple eventing.

An event emitter that probably does everything you actually need in only 70 lines of code.

Install

$ npm install --save voltrevo-event-emitter

Usage

'use strict';

var EventEmitter = require('voltrevo-event-emitter');

var ee = EventEmitter();

// events are asynchronous

ee.emit('foo', 'bar');

ee.on('foo', function(value) {
  console.log(value); // bar
});

// .once works as usual

ee.emit('boom');
ee.emit('boom');

ee.once('boom', function() {
  console.log('boom'); // only one boom
});

// .on and .once return Collection handles, which have .remove

ee.emit('unicorn');

var listener = ee.on('unicorn', function() {
  console.log('A wild unicorn appeared!'); // this never happens
});

listener.remove();
