Public Events

The library exposes several events which are happening during the runtime. You can subscribe to those events by using the PublicEventsService.

Currently the following events are supported:

export enum EventTypes {
/**
* This only works in the AppModule Constructor
*/
ConfigLoaded,
CheckingAuth,
CheckingAuthFinished,
CheckingAuthFinishedWithError,
ConfigLoadingFailed,
CheckSessionReceived,
UserDataChanged,
NewAuthenticationResult,
TokenExpired,
IdTokenExpired,
SilentRenewStarted,
SilentRenewFailed,
}

Notice that the ConfigLoaded event only runs inside the constructor of the AppModule as the config is loaded with the APP_INITIALIZER of Angular inside of the lib.

You can inject the service and use the events like this. Using the filter operator from RxJS you can decide which events you are interested in and subscribe to them.

import { PublicEventsService } from 'angular-auth-oidc-client';
constructor(private eventService: PublicEventsService) {
this.eventService
.registerForEvents()
.pipe(filter((notification) => notification.type === EventTypes.CheckSessionReceived))
.subscribe((value) => console.log('CheckSessionChanged with value', value));
}

The Notification being sent out comes with a type and a value.

export interface OidcClientNotification<T> {
type: EventTypes;
value?: T;
}
