Angular 6 RXJS Import Syntax? : <p>I'm migrating an Angular 5 app to the latest CLI and Angular 6 RC and all of my Observable imports are broken. I see that Angular 6 changes the way the imports work, but I can't find any definite reference as to how the syntax works.</p>

<p>I had this in 5 and it worked fine:</p>

<pre><code>import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/observable/throw';
</code></pre>

<p>Now with the new syntax I see that </p>

<pre><code>import { Observable, Subject, throwError} from 'rxjs';
import { map } from 'rxjs/operators';
</code></pre>

<p>The first two lines compile, but I can't figure out how to get catch and throw for example. .map() also throws a build error when used in code.</p>

<p>Anybody have a reference to how this is supposed to work?</p>
