'React firebase 9 how to delete current user account?
I'm doing a react base app that logs the user in with firebase auth. Everything there works fine, but now I want to allow the user to delete their account if the wish, but I'm not sure how to do it. I tried what was in the firebase documentacion but I get that I need to reauthenticate the user before as a matter of security, and I couldn't find tutorials of how to use the reauthenticateWithCredential() function.
Here is my profile code, a modal appears as a warming before the user deletes the account and then it calls a function in my firebase file. Since it appears that I need the user to write their password again there is a form in the modal that sends it to the function.
import { Fragment, useEffect, useState } from "react";
import { useRouter } from "next/router";
import { onSnapshot, query, where } from 'firebase/firestore';
import { useAuth } from "../../auth/authUserProvider";
import { usersColRef, deleteSignedUser, auth } from "../../firebase";
import styles from "../profileRender/profileRender.module.scss";
import Modal from "react-bootstrap/Modal";
const Profile = ({queryUserId}) => {
const router = useRouter();
const { authUser, loading } = useAuth();
const [userId, setUserId] = useState("");
const [showModal, setShowModal] = useState(false);
const [isUser, setIsUser] = useState(false);
const [isLoading, setIsLoading] = useState(true);
const [profileCreated, setProfileCreated] = useState(false);
const [userProfile, setUserProfile] = useState({
"userId" : "",
"username" : "",
"userDescription" : "",
"profilePicture" : ""
});
useEffect(() => {
//here i get the user profile info from firebase
}, [queryUserId ,userId, authUser, profileCreated, authUser]);
const renderEdit = () => {router.push("/profile/edit");}
const handleOpenModal = () => {setShowModal(true)};
const handleCloseModal = () => {setShowModal(false)};
const deleteUser = (e) => {
e.preventDefault();
deleteSignedUser(e.target[0].value);
}
const ProfileRender = () => {
if(profileCreated === false){
if(isLoading === true){
return (
<div className="page-background-setted-height">
<p>Loading...</p>
</div>
)
} else {
return (
<div className="page-background-setted-height">
<span className={styles.profile__title}>My profile</span>
<hr className={styles.profile__title__hr}></hr>
<div className={styles.profile__createAcount}>
<h3 className={styles.profile__createAcount__item}>Create your profile</h3>
<button onClick={renderEdit} className={`btn btn-dark ${styles.profile__createAcount__item}`}>Create</button>
</div>
</div>
)
}
} else {
if(isLoading === true){
return (
<div className="page-background-setted-height">
<p>Loading</p>
</div>
)
} else {
return(
<div className="page-background">
<div className={styles.profile}>
<span className={styles.profile__title}>My profile</span>
<hr className={styles.profile__title__hr}></hr>
<div className={styles.profile__top}>
<img className="" src={userProfile.profilePicture}/>
<div className={styles.profile__top__name}>
<div><h3>{userProfile.username}</h3></div>
</div>
</div>
<h4>About me...</h4>
<h6>{userProfile.userDescription}</h6>
{isUser &&
<div className={styles.profile__actions}>
<button onClick={renderEdit} className="btn btn-dark">Edit profile</button>
<button type="button" onClick={handleOpenModal} className="btn btn-danger">Delete profile</button>
</div>
}
</div>
///the modal element
<div>
<Modal show={showModal} onHide={handleCloseModal}>
<Modal.Header closeButton>
<Modal.Title>Are you sure?</Modal.Title>
</Modal.Header>
<Modal.Body>
<h3>Once you delete your profile, all your blogs will be deleted permanently.</h3>
<h5>In order to continue, please write your password again</h5>
<form onSubmit={deleteUser}>
<label>Password</label>
<input type="password"/>
<button type="submit" className="btn btn-danger">Delete profile</button>
</form>
</Modal.Body>
<Modal.Footer>
<button className="btn btn-primary" onClick={handleCloseModal}>
No, thanks
</button>
</Modal.Footer>
</Modal>
</div>
</div>
)
}
}
}
return (
<Fragment>
<ProfileRender />
</Fragment>
)
}
export default Profile;
And here is the function I call from firebase.
import { initializeApp } from "firebase/app";
import {
getAuth,
createUserWithEmailAndPassword,
signOut,
signInWithEmailAndPassword,
deleteUser,
EmailAuthProvider,
userProvidedPassword,
reauthenticateWithCredential
} from "firebase/auth";
import { getStorage } from "firebase/storage";
import {getFirestore, collection, addDoc, deleteDoc, doc, updateDoc } from 'firebase/firestore';
const firebaseConfig = {...};
initializeApp(firebaseConfig);
const db = getFirestore();
const auth = getAuth();
const storage = getStorage();
let user;
///AUTH FUNCTIONS
const createAccount = (values) => {
createUserWithEmailAndPassword(auth, values.email, values.password)
.then((cred) => {
user = cred.user;
localStorage.setItem("user", cred.user.uid);
})
.catch(err => {
console.log(err.message)
})
}
const signUserOut = () => {
signOut(auth)
.then(() => {
user = "";
})
.catch((err) => {
console.log(err)
})
};
const signUserIn = (values) => {
signInWithEmailAndPassword(auth, values.email, values.password)
.then((cred) => {
user = cred.user;
localStorage.setItem("user", cred.user.uid);
})
.catch((err) => {
})
};
const deleteSignedUser = async (password) => {
const = EmailAuthProvider.credential(
auth.currentUser.email,
password
)
const result = await reauthenticateWithCredential(
auth.currentUser,
credential
)
deleteUser(result).then(() => {
console.log("success in deleting")
localStorage.removeItem("user");
}).catch(err => console.log(err)); */
}
When I run this code I get this error:
TypeError: (0 , firebase_util__WEBPACK_IMPORTED_MODULE_0_.getModularInstance)(...).delete is not a function
Can someone help me with this?
