Usage

Event publish

To publish an event you must specify an eventId and an optional payload that will be collected by subscriber.

const payload = { foo: 'bar' };
publish('EVENT-ID', payload);

Event subscription

In order to subscribe to an event you must specify an eventId and a callback function that will be called when that event is received.

const callback = (payload: any): void => {};
subscribe('EVENT-ID', callback);

Event subscription (only once)

In order to subscribe to an event, only once, you must specify an eventId and a callback function that will be called when that event is received. For the next publishes of that event, this subscriber will not receive that event.

const callback = (payload: any): void => {};
subscribeOnce('EVENT-ID', callback);
