firebase.firestore() is not a function when trying to initialize Cloud Firestore

Question

When I try to initialize Firebase Cloud Firestore, I ran into the following error:

Uncaught TypeError: WEBPACK_IMPORTED_MODULE_0_firebase

If you're like me and like everything typed on typescript (it's the purpose, by the way), you can try:

import * as firebase from "nativescript-plugin-firebase";
import { User, firestore } from "nativescript-plugin-firebase";

import * as firebaseapp from "nativescript-plugin-firebase/app";

So you can do stuff like that:

firebase.getCurrentUser().then((user: User) => { /* something */ });

const mycollection : firestore.CollectionReference = firebaseapp.firestore().collection("mycollection");
