What is the best method for transferring data from Firestore into a Vue CLI project?

I am currently facing a challenge in importing data from a Firestore Database into my Vue CLI project. Despite following multiple tutorials, I have not been successful in making it work correctly. It appears that I am encountering difficulties in retrieving the data each time I attempt to do so, as my console.log output does not display anything.

Within a JS file named index.js located in a folder called db (I have omitted the content within quotations for security reasons on Stackoverflow), I have the following code snippet;

import firebase from "firebase";
import "firebase/firestore";

var config = {
  apiKey: "",
  authDomain: "",
  databaseURL: "",
  projectId: "",
  storageBucket: "",
  messagingSenderId: "",
  appId: "",
  measurementId: ""
};
firebase.initializeApp(config);
const db = firebase.firestore();
db.settings({ timestampsInSnapshotps: true });

Subsequently, in my component script, I include the following lines of code;

import db from '@/db'

export default {
  name: 'HelloWorld',
  data () {
    return {
        cafes: []
    }
  },
  created () {
      db.collection('cafes').get().then((snapshot) => {
        console.log(snapshot.docs);
      });
  }
}

I have come across information indicating that

db.settings({ timestampsInSnapshotps: true });
is no longer necessary. However, upon removal, it results in errors being displayed both in the terminal and browser.

The template structure is as follows;

<template>
  <div class="cafes">

    <h1>Here are some cafés</h1>

    <div for="cafe in cafes" v-bind:key="cafe.name">
        <div>
            {{cafe.name}}
        </div>
    </div>

  </div>
</template>

Any assistance or guidance would be greatly appreciated as I have been grappling with this issue for several days.

Here are the steps to follow:

Modify your Firebase db/index.js like so:

import firebase from 'firebase'
import 'firebase/firestore'

// Initialize firebase here
const config = {
    apiKey: "",
    authDomain: "",
    databaseURL: "",
    projectId: "",
    storageBucket: "",
    messagingSenderId: ""
}
firebase.initializeApp(config)

const db = firebase.firestore()

// Define firebase collections
const cafesCollection = db.collection('cafes')

export {
    db,
    cafesCollection
}

Update your Component as shown below:

const firebase = require("../db/index.js");  // Modify the path accordingly

export default {
  name: 'HelloWorld',
  data () {
    return {
        cafes: []
    }
  },
  created () {
      firebase.cafesCollection.get().then((snapshot) => {
        console.log(snapshot.docs);
        let cafesArray = [];
        snapshot.forEach(doc => {
          cafesArray.push({id: doc.id, ...doc.data()});
        });
        this.cafes = cafesArray;
      })
      .catch(error => {
         console.log(error);
      })
  }
}
