How to set up firebase responsive-native ignite "best practice"

Question

How can I set a fire base on an endless / ignited best way?

Now I'm starting and have some doubts, but I think you should add FirebaseConfig.js to / Config. Correctly? My FirebaseConfig.js file is now.

import Config from 'react-native-config'**
const firebase = require ( 'firebase');
// Initialize Firebase

import Config from 'react-native-config'

const firebase = require('firebase');

// Initialize Firebase
const firebaseConfig = {
    apiKey: Config.FIREBASE_API_KEY,
    authDomain: Config.FIREBASE_AUTH_DOMAIN,
    databaseURL: Config.FIREBASE_DATABASE_URL,
    storageBucket: Config.FIREBASE_STORAGE_BUCKET,
    messagingSenderId: Config.FIREBASE_MESSAGING_SENDER_ID
};
const firebaseApp = firebase.initializeApp(firebaseConfig);
