Creating a login page in React involves setting up components to handle user input, managing state, and incorporating functionality for authentication.

 Below is a simple example of a React login page:

Step 1: Set Up Your React Component

Create a new React component for the login page. This example uses a functional component with the `useState` hook:

import React, { useState } from 'react';

const LoginPage = () => {

  const [username, setUsername] = useState('');

  const [password, setPassword] = useState('');

  const [isAuthenticated, setIsAuthenticated] = useState(false);

  const handleLogin = () => {

    // Implement your authentication logic here (e.g., API request)

    // For simplicity, this example considers a hardcoded check

    if (username === 'user' && password === 'password') {


      alert('Login successful!');

    } else {


      alert('Invalid credentials. Please try again.');



  return (


      <h2>Login Page</h2>




          <input type="text" value={username} onChange={(e) => setUsername(} />


        <br />



          <input type="password" value={password} onChange={(e) => setPassword(} />


        <br />

        <button type="button" onClick={handleLogin}>Login</button>


      {isAuthenticated && <p>You are logged in!</p>}




export default LoginPage;

Step 2: Integrate the Component

Integrate the `LoginPage` component into your main application or any other component where you want to display the login page:

import React from 'react';

import LoginPage from './LoginPage';

const App = () => {

  return (


      <h1>Your App</h1>

      <LoginPage />




export default App;

Step 3: Style and Enhance

Style the components according to your application's design. Additionally, you may want to enhance the login page by:

- Adding form validation.

- Connecting to a backend for actual authentication (API request).

- Redirecting users upon successful login.

Note: In a real-world scenario, you should not hardcode usernames and passwords or perform authentication logic on the client side. Authentication should be handled securely on the server. This example focuses on the client-side aspects for simplicity.
