Cannot find rxjs select operator used by ngrx store.select

Cannot find select operator from rxjs library.

As I understand and explained here, ngrx store uses select operator from rxjs library when we call store.select method. The way it is currently working is if I imort the whole rxjs library:

import 'rxjs/Rx';

But this imports the whole rxjs operators, I only want to import the operators I need.

If I exclude rxjs/Rx import, get this error:

TypeError: this.store.select(...).first is not a function

I have also done a global search in npm rxjs package directory and that folder doesn't have any file with select in it. Really confusing.

If you don't want to import the entire library you can pick only the operators/Observables you want with for example:

import 'rxjs/add/operator/first';

You can see the full list here: https://github.com/ReactiveX/rxjs/tree/master/src/add/operator
