Cannot use "Observable.Of(value)"

Question

I'm migrating my app from Angular 5.2.9 to Angular 6.0.4

I ve upgraded from rxjs v5 to v6 And I've uninstalled : rxjs-compat (as I was told that it's no more needed)

So in the old syntax, I was used to return custom observable like this:

  public myObservable() {
    return Observable.of(true);
  }

It seems that this syntax is no more usefull as there is no more the operator "of"

the error is the following:

error TS2339: Property 'of' does not exist on type 'typeof Observable'.

So what is the alternative? Suggestions?

Answer 1

You just need to directly import it from rxjs.

import { of } from 'rxjs';

Answer 2

You should import of operator separately, like this:

import 'rxjs/add/observable/of';
