Strongly-Typed Events

Lightweight, strongly-typed events, with monitored subscriptions.

Documentation: API + WiKi.
Compatible with all existing events - see Extras.

Install

1npm i sub-events

Usage

On event-provider side:

1import {SubEvent} from 'sub-events';
2
3// creating a strongly-typed event: 
4const e: SubEvent<string> = new SubEvent();
5
6// triggering the event when needed:
7e.emit('hello');

API: SubEvent, emit

On event-consumer side:

1// subscribing to the event:
2const sub = e.subscribe((data: string) => {
3  // data = 'hello'
4});
5
6// cancel the subscription when no longer needed:
7sub.cancel();

API: Subscription, subscribe, cancel

Monitoring Subscriptions

Class SubEventCount extends SubEvent with event onCount, to observe the number of subscriptions:

1import {SubEventCount, ISubCountChange} from 'sub-events';
2
3// creating a strongly-typed event:
4const e: SubEventCount<string> = new SubEventCount();
5
6e.onCount.subscribe((info: ISubCountChange) => {
7    // number of subscriptions has changed;
8    // info = {newCount, prevCount} 
9});
10
11// any subscription will trigger event onCount:
12const sub = e.subscribe(data => {});
13
14// cancelling a subscription will trigger onCount:
15sub.cancel();

API: SubEventCount, onCount

Browser

When including directly from HTML, you can access all types under subEvents namespace:

1<script src="./node_modules/sub-events/dist"></script>
2<script>
3    const e = new subEvents.SubEvent();
4    e.subscribe(data => {
5        // data received
6    });
7</script>

Note that pre-built script includes only the core library, without the Extras, which you can bundle yourself as needed.
