Angular : how to call finally() with RXJS 6
use
throwErrorinstead ofObservable.throw, see https://github.com/ReactiveX/rxjs/blob/master/docs_app/content/guide/v6/migration.md#observable-classesfinallywas renamed tofinalizeand you'll use it insidepipe()among other operators.the same with
publish()andrefCount(). Both are operators you'll use insidepipe().
According to official document, You should change your code like this to avoid compile error: (You must throw exception in catchError method. finalize callback method has no argument.)
import { catchError, finalize } from 'rxjs/operators';return next.handle(clonedreq).pipe( catchError(error => { console.log('error occured:', error); throw error; }), finalize(() => { console.log('finalize') }));It is successfully compiled in Angular CLI: 7.1.4.
