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();
  }
}
