    Strongly Typed Events - Signals

    Signals are the most barebone of all events. They don't contain any data. They just invoke the registered handler.

    Subscription made easy

    An example says more than a 1000 words. Imagine if you have events like this on your class:

    let clock = new Clock("Smu", 1000);
    
    //log the ticks to the console - this is a signal event
    clock.onTick.subscribe(() => console.log("Tick!"));

    Events made easy

    So let's look at the implementation from a TypeScript perspective. (Do you program NodeJs without typescript? Check this)

    import { SignalDispatcher } from "ste-signals";
    
    class Clock {
      private _onTick = new SignalDispatcher();
      private _ticks: number = 0;
    
      constructor(public name: string, timeout: number) {
        setInterval(() => {
          this._ticks += 1;
          this._onTick.dispatch();
        }, timeout);
      }
    
      public get onTick() {
        return this._onTick.asEvent();
      }
    }
