Rxjs How To Return Observable With Default Error Handling Function

In my application I have some methods returning an Observable: public myMethodReturningObs(...): Observable { return this.http.get(...); // this will return an Observable } then

Solution 1:

You can catch error in base observable, log it and propogate further

public myMethodReturningObs(...): Observable {
  return this.http.get(...)
        .catch(e => {
          // log error
          console.error('Failed', e);
          // return same error, so subscriptions also fail
          return Rx.Observable.throw(e)
        });
}
