Hi, I don’t use the PWA starter, but I did have some issues myself importing firebase into Quasar when I started. I can’t say I know the best way to do this, but I currently use the following, and it works for me: import firebase from 'firebase/app'; import "firebase/auth"; import "firebase/firestore"; import "firebase/storage"; const config = { stuff }; firebase.initializeApp(config); const auth = firebase.auth(); const firestore = firebase.firestore(); const storage = firebase.storage(); export {firebase, auth, firestore, storage}; And, then I import the pieces I need like this: import { firebase, auth, firestore, storage } from './firebase.js';
