Observable.of is not a function

Question

I am having issue with importing Observable.of function in my project. My Intellij sees everything. In my code I have:

import {Observable} from

Upgraded from Angular 5 / Rxjs 5 to Angular 6 / Rxjs 6?

You must change your imports and your instantiation. Check out Damien's blog post

Tl;dr:

import { Observable, fromEvent, of } from 'rxjs';

const yourResult = Observable
    .create(of(yourObservable))
    .startWith(null)
    .map(x => x.someStringProperty.toLowerCase());

//subscribe to keyup event on input element
Observable
    .create(fromEvent(yourInputElement, 'keyup'))
    .debounceTime(5000)
    .distinctUntilChanged()
    .subscribe((event) => {
        yourEventHandler(event);
    });
