Is it possible to strongly type the events in much the same way as nest-emitter?
I am having issues using nest-event. I have NestEventModule imported in app.module
imports: [ NestEventModule, ... ]
Then I am injecting it in my service:
constructor(private nestEvent: NestEventEmitter)
And finally I emit an event:
this.nestEvent.emit('TESTEMIT');
This emit is triggered when I do a GET request to my API.
But all I get is this error:
error: ┏ Cannot read property 'has' of undefined: +6ms
error: ┃ [1] TypeError: Cannot read property 'has' of undefined
error: ┃ [2] at NestEventEmitter.emitter (/home/user/code/core/node_modules/nest-event/nest-event-emitter.js:42:42)
error: ┃ [3] at NestEventEmitter.emit (/home/user/code/core/node_modules/nest-event/nest-event-emitter.js:24:35)

error: ┗ [7] at processTicksAndRejections (internal/process/task_queues.js:93:5)
It happens right here: if (!this.nestEvent.getEmitters().has(emitter)) {
I tried creating different emitter classes with @emitter() decorator but it doesn't help.
I also tried executing configure() method manually as I've seen in the code it is used for setting emitters in a Map, also doesn't help.
Any suggestions? Thanks in advance
