Using library from npm package #google/maps for Ionic 2 project? - node.js

Question

this could be silly question from newcomer, but I wonder about can I use Node.js library with stack that Ionic 2 (Node package system with package.json , Angular 2, Cordova) provides. I found interesting for my project library from Google ( I need geocoding for some form validation).
For this moment I added this package to package.json with
npm install #google/maps --save
npm i
I created provider for client consuming, added
import {} from '#google/maps';
and understood that I need some sort of typings for TS:) Is it really an option to use separate from Ionic and Angular libraries or am I wasting my time?
Update
Thanks to #Ivaro18, I managed how to add typings to my project:
npm install #types/google-maps --save
Now I can make something like this:
import GoogleMapsLoader = require('google-maps');
GoogleMapsLoader.URL = 'https://maps.googleapis.com/maps/api/js';
GoogleMapsLoader.KEY = 'qwertyuiopasdfghjklzxcvbnm';
GoogleMapsLoader.LIBRARIES = ['geocode()', 'places'];
GoogleMapsLoader.CLIENT = 'yourclientkey';
GoogleMapsLoader.CHANNEL = 'myChannel';
GoogleMapsLoader.LANGUAGE = 'fr';
GoogleMapsLoader.REGION = 'GB';
GoogleMapsLoader.VERSION = '3.14';
GoogleMapsLoader.WINDOW_CALLBACK_NAME = '__google_maps_api_provider_initializator__';
#Injectable()
export class GoogleMapsClientProvider {
constructor(public http: Http) {
console.log('Hello GoogleMapsClientProvider Provider');
GoogleMapsLoader.createLoader();
};
}
I found about this here but I'm not sure how to use this stuff,e.g.
GoogleMapsLoader.KEY = 'qwertyuiopasdfghjklzxcvbnm';
GoogleMapsLoader.CLIENT = 'yourclientkey';
What is what? Someone tried this lib before? My mandatory task is to use geocoding for address validation.
