Why doesn't subscription work after component activation?

Question

Angular

I have a service that provides a Subject subscription.

Somewhere in the application a message is sent and listened to in another component.

The problem is that the component is activated by the condition *ngIf

<app-data *ngIf="data"></app-data>

Where data comes from the listener Subject .

In turn, in the component itself, I once again want to listen to Subject .

Tried in `ngOnChanges(): void {}, ngOnInit(): void {}`

Such a suspicion that when creating a component according to the ngIf condition - it scores on subscriptions inside

Answer 1

How did you determine that the subscription is not working? It is possible that the component was created after the subject had a value and therefore did not have time to receive anything.
