hitman

It's all about fulfilling contracts.

Happy path (works just like an event emitter):

  var Hitman = require('hitman').Hitman;

  var emitter = new Hitman(['1', '2']);

  emitter.on('1', function() {
    console.log('hello world');
  });

  emitter.emit('1');

Wrapping an external EventEmitter:

  var Hitman       = require('hitman').Hitman,
      EventEmitter = require('events').EventEmitter;

  var ext_emitter = new EventEmitter(),
      emitter = new Hitman(['1', '2'], { emitter: ext_emitter });

  emitter.on('1', function() {
    console.log('hello world');
  });

  emitter.emit('1');

Both of the following examples will throw an error:

  var Hitman = require('hitman').Hitman;

  var emitter = new Hitman(['1', '2']);

  emitter.on('3', function() {
    console.log('hello world');
  });

  var Hitman = require('hitman').Hitman;

  var emitter = new Hitman(['1', '2']);

  emitter.emit('3');
