QEmitter
Node.js event emitter with promises support.
Node.js builtin EventEmmiter
class executes all handlers synchronously without
waiting for completion of any async operations that may happen inside.
QEmitter
is the subclass of EventEmmiter
which adds ability to return a
promise from event handler and wait until it resolved. Just use emitAndWait
instead of emit
:
var emitter = new QEmitter();
emitter.on('event', function() {
return Q.delay(1000);
});
emmiter.emitAndWait('event')
.then(function() {
console.log('All handlers finished');
});
emitAndWait
returns Q
promise.
