Propagate events from one event emitter into another
$ npm install propagate
var ee1 = new EventEmitter();
var ee2 = new EventEmitter();
propagate(ee1, ee2);
ee2.on('event', function(a, b) {
console.log('got propagated event', a, b);
});
ee1.emit('event', 'a', 'b');
You can unpropagate by ending the propagation like this:
var ee1 = new EventEmitter();
var ee2 = new EventEmitter();
var p = propagate(ee1, ee2);
// ...
p.end();
var ee1 = new EventEmitter();
var ee2 = new EventEmitter();
var p = propagate(['event1', 'event2'], ee1, ee2);
