Hi Jonas,
I'm not sure I can follow exactly what you are doing, but it seems you want
some kind of eventbus to communicate between some parts of your app that
don't have a direct parent-child relation. Did i get that right?
If so, create a service, and inject it in the places where you need it.
something along those lines:
interface Message {
channel: string;
payload: any;
}
@Injectable()
export class EventBus {
private message$ = new Subject<Message>();
/**
* Push a 'event' into the observable
* @param {channel, payload} Makes sure the Message interface is applied
*/
publish({ channel, payload }: Message): void {
this.message$.next({ channel, payload });
}
/**
* Return an observable that listens to a specific 'channel'
* the observable will contain the payload that is published
* @param channelName -- a string to identify the channel
*/
of(channel: string): Observable<any> {
return this.message$.filter(m => m.channel === channel).map(m => m.payload);
}
}
will take care of most of your issue.
Regards
Sander
