🔥 Firebase Setup

Firebase Setup

npm install firebase react-firebase-hooks

• Firebase JS works in both the browser and Node.js
• react-firebase-hooks abstracts realtime Firebase streams to React hooks

Firebase Lib

Export common Firebase SDKs and utilities.

import firebase from 'firebase/app'
import 'firebase/auth';
import 'firebase/firestore';
import 'firebase/storage';

const firebaseConfig = {
    // your config
};
  
if (!firebase.apps.length) {
    firebase.initializeApp(firebaseConfig)
}

export const auth = firebase.auth();
export const firestore = firebase.firestore();
export const storage = firebase.storage();

Update September 2021

If you are using Firebase Version 9 you may end up with this error:

TypeError: Cannot read property 'apps' of undefined

Option 1 Downgrade to firebase version 8, by running:

npm install firebase@8.2.1

Option 2 Alternatively, if you wish to continue using firebase version 9, change your imports as follows:

import firebase from 'firebase/compat/app'
import 'firebase/compat/auth';
import 'firebase/compat/firestore';
import 'firebase/compat/storage';

Check out the Firebase Version 9 Migration guide for additional details on the new Firebase SDKs.

To see the fully updated v9 source code, check out the v9 branch on Github

Optional

Consider setting up the Firestore emulator to work with mock data on your local machine.
