Form user redirectnow catch error error alert username

Firstly, We would need to set up the backend using ExpressJs and Mongodb. You can create a MongoDB database to store user information and their respective roles. You can then set up an ExpressJs server to handle HTTP requests from the client.

Once the backend is set up, you can create the front end of the application using Reactjs and Tailwind CSS. You can create a registration page where the user can enter their name, email id, phone number, and password. The registration page can then send a POST request to the ExpressJs server, which can store the user information in the MongoDB database.

User details are stored in the MongoDB database via the ExpressJs server
User logs in using their credentials

Backend:

Set up the MongoDB database connection using a package like a mongoose.
Create a schema for the user and todo models.

Frontend:

Create a login page that sends a POST request to the ExpressJs /login endpoint and saves the JWT token in local storage.
Create a Todo list page that fetches all todos from the ExpressJs /todos endpoint and displays them in a table.

Set up React web application:

npm -v

Create the React app:

npx create-react-app expengo -y

Add required dependencies:

Create a React Context for user:

export const UserContext = createContext(); export const UserProvider = ({ children }) => { const [user, setUser] = useState(null);

const emailPasswordLogin = async (email, password) => {

await app.emailPasswordAuth.registerUser(email, password); return emailPasswordLogin(email, password);

} catch (error) { throw error;

return app.currentUser;

} catch (error) { throw error;

return true;

} catch (error) { throw error

</UserContext.Provider>;

}

Create a PrivateRoute page:

const location = useLocation();

const redirectLoginUrl = `/login?redirectTo=${encodeURI(location.pathname)}`; return !user ? <Navigate to={redirectLoginUrl} /> : <Outlet /> ;

const Login = () => {

const navigate = useNavigate(); const location = useLocation();

};

const redirectNow = () => {

const fetchedUser = await fetchUser(); if (fetchedUser) {

redirectNow();

loadUser(); // eslint-disable-next-line react-hooks/exhaustive-deps

}, []);

} catch (error) {

if (error.statusCode === 401) {

};

return <form style={{ display: "flex", flexDirection: "column", maxWidth: "300px", margin: "auto" }}>

<TextField label="Password" type="password" variant="outlined" name="password" value={form.password}

onChange={onFormInputChange} style={{ marginBottom: "1rem" }}

<p>Don't have an account? <Link to="/signup">Signup</Link></p>

</form>

import { Link, useLocation, useNavigate } from "react-router-dom"; import { UserContext } from "../contexts/user.context";

const Signup = () => {

const onFormInputChange = (event) => { const { name, value } = event.target; setForm({ ...form, [name]: value });

};

const user = await emailPasswordSignup(form.email, form.password); if (user) {

redirectNow();

return <form style={{ display: "flex", flexDirection: "column", maxWidth: "300px", margin: "auto" }}>

<h1>Signup</h1>

onInput={onFormInputChange} style={{ marginBottom: "1rem" }}

}

export default Signup;

Create a homepage:

const loggedOut = await logOutUser(); if (loggedOut) { window.location.reload(true);

}

<h1>Welcome to Expengo</h1>

Putting it all together in App.js:

import { BrowserRouter, Route, Routes } from "react-router-dom"; import { UserProvider } from "./contexts/user.context";

import Home from "./pages/Home.page"; import Login from "./pages/Login.page";

</Routes>

</UserProvider>

Launch your React app

npm start
