const firebaseConfig = {
apiKey: "AIzaSyBEDYLiNmyEg41MQ6aSKZl-jKgnHeU4xEk",
authDomain: "fir-9-rush.firebaseapp.com",
projectId: "fir-9-rush",
storageBucket: "fir-9-rush.appspot.com",
messagingSenderId: "322306232885",
appId: "1:322306232885:web:04f99272f4dfa124ec177c"
};create instances of firebase services
import { initializeApp } from 'firebase/app'
import { getFirestore } from 'firebase/firestore'
import { getAuth } from 'firebase/auth'
import { getStorage } from 'firebase/storage'
function initialize() {
// init firebase app
const firebaseApp = initializeApp(firebaseConfig)
// init services
// pass `firebaseApp` instance is optional, we can call following functions without it and from any place
const firestore = getFirestore(firebaseApp)
const auth = getAuth(firebaseApp)
const storage = getStorage(firebaseApp)
return { firebaseApp, firestore, auth, storage }
}
export const { firebaseApp, firestore: db, auth, storage } = initialize()
