How to throw an observable error manually?

javascript angular typescript rxjs

if (response.success == 0) {   throw Observable.throw(response);   }

Edit for rxjs 6:

if (response.success == 0) {   throw throwError(response);   }

javascript angular typescript rxjs

rxjs 6

import { throwError } from 'rxjs';if (response.success == 0) {  return throwError(response);  }

rxjs 5

import { ErrorObservable } from 'rxjs/observable/ErrorObservable';if (response.success == 0) {  return new ErrorObservable(response);  }

What you return with ErrorObservable is up to you

javascript angular typescript rxjs

with rxjs 6

import { throwError } from 'rxjs';throwError('hello');
