Vue: Firebase: Error in mounted hook: "FirebaseError: No Firebase App '[DEFAULT]' has been created

I am building Vue SPA and have checked many posts before posting this.

I am not sure what I am doing wrong.

Below is my App.Vue: 

<template>
    <div id="app">
        <Navigation />
        <router-view class="container" :user="user" />
    </div>
</template>

<script>
import Navigation from '@/components/Navigation.vue';
// import db from './db.js';
import Firebase from 'firebase';
export default {
    name: 'App',
    data: function() {
        return {
            user: null,
        };
    },
    mounted() {

        Firebase.auth().onAuthStateChanged(user => {
            if (user) {
                this.user = user.email;
            }
        });
    },
    components: {
        Navigation,
    },
};
</script>

<style lang="scss">
$primary: #37c6cf;
@import '../node_modules/bootstrap/scss/bootstrap';
</style>

Note: I have commmented the import from db.js which can be find after the first import. If I enable it Vue CLI is throwing different error.

in db.js: 

import firebase from 'firebase';
const firebaseConfig = {
    apiKey: 'yourkey',
    authDomain: 'domainnew.firebaseapp.com',
    databaseURL: 'yourdomain.com',
    projectId: 'yourproject',
    storageBucket: 'test',
    messagingSenderId: '454545',
    appId: '1:444d96:web:d78df',
    measurementId: 'G-69599595',
};

// Initialize firebase
const firebaseApp = firebase.initializeApp(firebaseConfig);
firebase.analytics();
export default firebaseApp.firestore();

In the console I am keep getting below two errors and my Vue is not retrieving my email address from Firebase.

enter image description here

Can any one pleas help on this.

The following should do the trick:

db.js file

import firebase from 'firebase/app';
import "firebase/analytics";
import 'firebase/firestore';
import 'firebase/auth';

const firebaseConfig = {
    apiKey: 'yourkey',
    authDomain: 'domainnew.firebaseapp.com',
    databaseURL: 'yourdomain.com',
    projectId: 'yourproject',
    storageBucket: 'test',
    messagingSenderId: '454545',
    appId: '1:444d96:web:d78df',
    measurementId: 'G-69599595',
};

firebase.initializeApp(firebaseConfig);



const db = firebase.firestore();
const auth = firebase.auth();
const analytics = firebase.analytics();

export { db, auth, analytics };

App.js file

<template>
    <div id="app">
        <Navigation />
        <router-view class="container" :user="user" />
    </div>
</template>

<script>
import Navigation from '@/components/Navigation.vue';
const fb = require('./db.js');

export default {
    name: 'App',
    data: function() {
        return {
            user: null,
        };
    },
    mounted() {

        fb.auth.onAuthStateChanged(user => {
            if (user) {
                this.user = user.email;
            }
        });
    },
    components: {
        Navigation,
    },
};
</script>

<style lang="scss">
$primary: #37c6cf;
@import '../node_modules/bootstrap/scss/bootstrap';
</style>
