Answer 1

i am sorry for the delay but i just get this problem today and fixed like this. i solve this issue like this: first import like this:

import {debounceTime} from 'rxjs/operators';
import {pipe} from 'rxjs'

Then create a const like this (i tried to do directly without duplicating pipe but didn´t work so i found this solution):

const debouncetime = pipe(debounceTime(1000));

And then use it before you subscribe for example i was doing an email validator with messages:

const emailControl = this.registerForm.get('email');
    emailControl.valueChanges
     .pipe(debouncetime)
     .subscribe(value => this.setEmailMessage(emailControl))

dont know if its the best solutions but it works perfectly. I hope it helps some one!
