I tried all these scripts and this is my firebase file

import firebase from "firebase/app";
var firebaseConfig = {...};
let fireDb = firebase.initializeApp(firebaseConfig);
export default fireDb.database().ref();

and this is where I call it

import React from "react";
import UserForm from "./UserForm";
import firebaseDb from "../firebase.js";

const UserProfile = () => {
  const AddOrEdit = (obj) => {
    firebaseDb.child("contacts").push(obj, (err) => {
      if (err) {
        console.log(err);
      }
    });
  };
  return (
    <>
      <div class="container py-4">
        <div class="p-5 mb-4 bg-light rounded-3">
          <div class="container-fluid py-5">
            <h1 class="display-10 fw-bold">Profile Page</h1>
          </div>
        </div>

        <div class="row align-items-md-stretch">
          <div class="col-md-6">
            <div class="h-100 p-5 text-white bg-dark rounded-3"></div>
          </div>
          <div class="col-md-6">
            <div class="h-100 p-5 bg-light border rounded-3">
              <UserForm AddOrEdit={AddOrEdit} /> // here I send the function as props to user form
            </div>
          </div>
        </div>
      </div>
    </>
  );
};

export default UserProfile;

this is a pic for the error

You're only importing firebase/app, which means the Realtime Database is not available in your code your.

to fix that, add:

import "firebase/database";

This then makes firebase.database() available as a side-effect.
