"Silently update the value of an Rxjs Observable without triggering notifications to subscribers

I'm currently working on updating an observable without alerting the subscribers to the next value change. In my project, I am utilizing Angular Reactive Forms and subscribing to the form control's value changes Observable in the following manner:

this.form.get('someSelection').valueChanges.susbscribe(value => this.selectionValue = value);

There are instances where I need to manually update the control's value, but when I do this, the valueChanges observable triggers and emits the new value. Is there a way for me to silently update the observable without notifying the subscribers?

Answer №1

Don't forget to utilize the emitChange parameter while assigning a fresh value :

this.updateValue(newValue, {emitChange:true});
