Question: I see eventemitter3 in the dependancies, and you do not using it anywhere

I wondered the exact same thing. Instead it looks like he is using the native node event dispatcher in https://github.com/santiq/bulletproof-nodejs/blob/master/src/decorators/eventDispatcher.ts

Yep, I'm sorry guys, I ended up using the package event-dispatch instead of eventemitter3 because it has the decorators for Typescript.

But since event-dispatch is now deprecated (see #3 ), I want to change it to eventemitter3
