$eventBusProvider

$eventBusProvider creates the injectable $eventBus singleton and exposes the same instance through the global Angular service for integrations outside dependency injection.

Exact signatures live in TypeDoc:

• PubSubProvider
• PubSub

Replace The Bus

angular.module("demo", []).config(($eventBusProvider) => {
  $eventBusProvider.eventBus = new MyCustomPubSub();
});

Most applications should use the default PubSub instance. Replace it only when you need custom dispatch, instrumentation, or compatibility with another event system.

For service usage, see $eventBus.
