# Strongly Typed Events - Signals
Signals are the most barebone of all <a href="https://www.npmjs.com/package/strongly-typed-events">events</a>. They don't contain
any data. They just invoke the registered handler. 

Version 4.0.0 requires Node.js 22.22.2 or newer.

[![npm version](https://badge.fury.io/js/ste-signals.svg)](https://badge.fury.io/js/ste-signals)

### Subscription made easy
An example says more than a 1000 words. Imagine if you have events like this on your class:
```typescript
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? <a href="https://github.com/KeesCBakker/Strongly-Typed-Events-for-TypeScript/blob/master/documentation/HowToUseInNodeJs.md">Check this</a>)

```typescript
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();
  }
}
```
