You are using HttpModule which is deprecated you should use HttpClientModule instead
Regarding the error

property map doesn't exist on type 'Observable'

RxJS v5.5.2+ has moved to Pipeable operators to improve tree shaking and make it easier to create custom operators. now operators need to be combined using the pipe method
Refer This
New Import

import { map} from 'rxjs/operators';

Example

myObservable
  .pipe(map(data => data * 2),)
  .subscribe(...);

Modified code

    getShoppingItems() { return this.http.get('localhost:3000/api/items')
    .pipe(map(res => res.json())); } }
