firebase configuration

import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
  apiKey: "xxxxx",
  authDomain: "xxxxx.firebaseapp.com",
  projectId: "portfolio-279ef",
  storageBucket: "xxxxx.appspot.com",
  messagingSenderId: "7xxxxx2",
  appId: "1:7xxx2:web:7xxxf"
};
const Firebaseapp = initializeApp(firebaseConfig);
export const auth=getAuth();
export default  Firebaseapp;

With new firebase functional approach, you need to include auth parameter like this:

createUserWithEmailAndPassword(auth, email, password)
