auth.createUserWithEmailAndPassword is not a function, react - javascript

It's pretty much self explanatory, can you guys please help me fix this issue? I've been struggling for 2 hours.
I want createUserWithEmailAndPassword to work in Register.jsx so I can later on sign in Login.jsx with the same information. However on the website when I click the submit button in Register.jsx, auth.createUserWithEmailAndPassword is not a function pops out

You're using the v9 SDK version, which uses a modular API with top-level functions. So createUserWithEmailAndPassword is not longer a method on the auth object, but is now a top-level function that you have to import similar to what you do for getAuth and to which you then pass the auth object as its first parameter:
createUserWithEmailAndPassword(auth, "username", "password")
When you are programming this new API or getting errors otherwise, I recommend keeping the documentation handy. In this case you can see code similar to what you're trying and what I have above in the documentation on creating a user. Also have a look at the blog post introducing the modular SDK, and the upgrade guide.

React.js, How to fetch the properties in a URL pathname?

I'm trying to fetch the uid and token through the URL pathname using match in my React app. But I got error:
Uncaught TypeError: n is undefined
and this is my code snippet:
const ResetPasswordConfirm = ( {match, reset_password_confirm} ) => {
...
const onSubmit = e=> {
e.preventDefault();
const uid = match.params.uid;
const token = match.params.token;
reset_password_confirm(uid, token, new_password, re_new_password);
setRequestSent(true);
};
};
According to this thread: https://stackoverflow.com/questions/70609785/uncaught-typeerror-match-is-undefined#:~:text=react%2Drouter%2Ddom%20v5,render%20or%20children%20prop%20functions.
It says it might have something to do with the version of react router, so I tried to use useParams(), but I found it hard to implement it...
I also tried to use matchPath, but I can find few examples.
Can anybody help me with this issue please?
Update:
react-router-dom version: 6.8.0
ResetPasswordConfirm is running in my container package.
import React, { useState } from "react";
import { Navigate, useParams } from 'react-router-dom';
import { connect } from 'react-redux';

const [requestSent, setRequestSent] = useState(false);
const [formData, setFormData] = useState({
new_password: '',
re_new_password: ''
});
const { new_password, re_new_password } = formData;
const onChange = e => setFormData({ ...formData, [e.target.name]: e.target.value });
const onSubmit = e=> {
e.preventDefault();
const uid = match.params.uid;
const token = match.params.token;
reset_password_confirm(uid, token, new_password, re_new_password);
setRequestSent(true);
};
// Is the user sending the request?

Sorry for the lo-fi question. I will try to do better.
I tried to use useParams to fetch my uid
const onSubmit = e => {
...
let{uid} = useParams()
}
There are no longer route props in react-router-dom routed components, i.e. there is not any injected match prop. You'll use the useParams hook to access the route path params in RRDv6. You can't use React hooks in nested callbacks, they must be called in the function body of a React component or in custom React hooks. Use the useParams hook in the component body and destructure the uid and token path params. Since you are using hooks you may as well also import and use the useNavigate hook and issue the navigation action at the end of the form's onSubmit handler instead of enqueueing a state update.
import React, { useState } from "react";
import { useParams, useNavigate } from 'react-router-dom';
import { useDispatch } from 'react-redux';
import { reset_password_confirm } from '../actions/auth';
const ResetPasswordConfirm = () => {
const dispatch = useDispatch();
const navigate = useNavigate();
const { uid, token } = useParams();
const [formData, setFormData] = useState({
new_password: '',
re_new_password: ''
});
const onChange = e => setFormData(formData => ({
...formData,
[e.target.name]: e.target.value
}));
const onSubmit = e => {
e.preventDefault();
const { new_password, re_new_password } = formData;
dispatch(reset_password_confirm(uid, token, new_password, re_new_password));
navigate("/");
};
return (
...
);
};
export default ResetPasswordConfirm;

After registering I want to send user to Login form but I am not sure how should I do it. Here is App.js just in case:
import React, {useState} from 'react';
import './App.css';
import { Register } from './Register';
import { Login } from './Login';
import { ProfileSetUp } from './ProfileSetUp';
function App() {
const [currentForm, setCurrentForm] = useState('login');
const toggleForm = (formName) => {
setCurrentForm(formName);
}
return (
<div className="App">
{
currentForm === "login" ? <Login onFormSwitch={toggleForm} /> : <Register onFormSwitch={toggleForm} />
}
</div>
);
}
export default App;
I am not sure how React page is represented so I am not sure how to use window.open() etc.
I followed one tutorial where is shown how to make this toggle switch function, which I like but I think that will make me troubles with other pages.
You can use the react-router package to link between different pages and pass data. Here is the documentation for the package https://reactrouter.com/en/main.
If you don't want to navigate to different components using routing, you could just use state variables to show/hide components included in a single parent component.

useNavigate hook called inside useEffect causing infinite loop

i am using the useNavigate hook inside of react to direct users to a home page after successful login. everything i've read online suggests that i should use the useNavigate hook inside of a useEffect block, but when i do so, it triggers an infinite loop: Warning: Maximum update depth exceeded. This can happen when a component calls setState inside useEffect, but useEffect either doesn't have a dependency array, or one of the dependencies changes on every render.
the odd thing is, though, that the warning only seems to occur after logging in for a second time. what i mean is that it will work on the first login after starting the server & client, but logging in a second, third, etc. time results in a Maximum update depth exceeded warning.
i use the useNavigate hook in two separate files, a login for users and a login for admin, both of which are below.
for further clarification on the issue arising only on the second login and beyond, it occurs regardless of whether i log in as admin or as a user. for instance, if my first login is as an admin, the Maximum update depth exceeded warning will occur regardless of whether my next login is as a user or as an admin. the same is true if my first login is as a user.
what i've tried so far:
removing navigate as from the dependency arrays (results in same warning)
removing the useEffect blocks (results in warnings to put the useNavigate hook inside of a useEffect hook. the login functionality breaks)
removing the dependency array altogether (results in the same warning)
the error when i login as user:
react-dom.development.js:86 Warning: Maximum update depth exceeded. This can happen when a component calls setState inside useEffect, but useEffect either doesn't have a dependency array, or one of the dependencies changes on every render.

You need to listen for changes in your localStorage. Try this:
const checkAuth = () => {
if (localStorage.getItem("authToken")) {
navigate("/home");
}
}
useEffect(() => {
window.addEventListener("storage", checkAuth);
return () => {
window.removeEventListener("storage", checkAuth)
}
}, []);

How to display auth errors with p tag

how to display to user an auth error differently than with alert?
For example: User will type a bad password, and a p tag will tell him, that he typed uncorrect password.
Using Firebase v9 and React.
Some code:
import React from 'react'
import { Link, useNavigate } from "react-router-dom";
import { UserAuth } from '../context/AuthContext';
import { useState } from 'react';
const Signin = () => {
const [email, setEmail] = useState('')
const [password, setPassword] = useState('')
const [error, setError] = useState('');
const navigate = useNavigate();
const { signIn } = UserAuth();
const handleSubmit = async (e) => {
e.preventDefault();
setError('')
try{
await signIn(email, password)
navigate("/");
} catch (e) {
setError(e.message)
alert(e.message)
}
}
return (
<div className='Signin'>Signin
<form onSubmit={handleSubmit}>
<label>Email</label>
<input onChange={(e) => setEmail(e.target.value)} type="email"/>
<label>password</label>
<input onChange={(e) => setPassword(e.target.value)} type="password"/>
<button type="submit">Sign up</button>
<p className='errorp'></p>
</form>
</div>
)
}
export default Signin
Thank you!
Something like {error && <p className='errorp'>{error}</p>}
