Warning: It looks like you're using the development build of the Firebase JS SDK

Question

I\'ve integrated Firebase into my React.js app as such: https://firebase.google.com/docs/database/web/start

fire.js:

import firebase from \'firebase\'

var          


        

Answer 1

The proper way to import firebase and getting rid of the warnings is:

Always import this way

import firebase from 'firebase/app';

Then import each sub-modules (each firebase service) as needed

import 'firebase/auth';        // for authentication
import 'firebase/storage';     // for storage
import 'firebase/database';    // for realtime database
import 'firebase/firestore';   // for cloud firestore
import 'firebase/messaging';   // for cloud messaging
import 'firebase/functions';   // for cloud functions
