REACT_APP_FIREBASE_PROJECT_ID=
REACT_APP_FIREBASE_STORAGE_BUCKET=
REACT_APP_FIREBASE_MESSAGING_SENDER_ID=
REACT_APP_FIREBASE_APP_ID=

const firebaseConfig = {
    apiKey: process.env.REACT_APP_FIREBASE_API_KEY,
    authDomain: process.env.REACT_APP_FIREBASE_AUTH_DOMAIN,
    projectId: process.env.REACT_APP_FIREBASE_PROJECT_ID,
    storageBucket: process.env.REACT_APP_FIREBASE_STORAGE_BUCKET,
    messagingSenderId: process.env.REACT_APP_FIREBASE_MESSAGING_SENDER_ID,
