How to write rxjs catch and map functions using pipe after update

since rxjs got updated, my code is not working anymore. I realised that I need to use pipe and instead of catch catchError, but still something I'm missing. See code below. Thankful for help.

  public getAllTodos(): Observable<Todo[]> {
    return this.http.get(API_URL + '/todos')
    .pipe(
      map(response => {
       const todos = response.json();
       return todos.map((todo) => new Todo(todo));
      }),
      catchError(err => {
        this.handleError(err);
      })
   );
  }



private handleError (error: Response | any) {
console.error('ApiService::handleError', error);
return Observable.throw(error);
