@jtjs/event

Environment: Any

@jtjs/event provides a simple but powerful object-oriented event implementation. It has no dependencies, is extremely lightweight, and is fully typed.

How to Use

Create your event:

import { Event } from '@jtjs/event';

type ThemeChangeHandler = (themeName: string) => void;

const onThemeChange = new Event<ThemeChangeHandler>();

Subscribe to your event…

Until you unsubscribe:

onThemeChange.subscribe((themeName) => {
  console.log(`Theme changed to ${themeName}!`);
});

For just one trigger:

onThemeChange.once((themeName) => {
  console.log('Just once!');
});

Trigger your event:
```
onThemeChange.trigger('light');
```

Unsubscribe from your event…

With the return from subscribe:

const unsub = onThemeChange.subscribe((themeName) => {
  console.log('beep boop');
});

unsub();

With the reference to your handler:

const handler = (themeName: string) => {
  console.log('beep boop');
};

onThemeChange.subscribe(handler);

onThemeChange.unsubscribe(handler);
