react login page in javascript

To create a login page in React, you can follow these steps:

First, create a new React component for your login page. You can name it "Login" or any other relevant name.


import React, { useState } from "react";

function Login() {
  // Use state to store user input
  const [username, setUsername] = useState("");
  const [password, setPassword] = useState("");

  // Handle form submission
  const handleSubmit = (event) => {
    event.preventDefault(); // Prevent the page from reloading
    // TODO: Implement authentication logic
  };

  // Render form with input fields and submit button
  return (
    <form onSubmit={handleSubmit}>
      <input type="text" placeholder="Username" value={username} onChange={(event) => setUsername(event.target.value)} />
      <input type="password" placeholder="Password" value={password} onChange={(event) => setPassword(event.target.value)} />
      <button type="submit">Login</button>
    </form>
  );
}

export default Login;

Use the useState hook to store user input, username and password, in the component's state.
Create a function to handle form submission. This function should prevent the default behavior of submitting the form (i.e., reloading the page), and implement your authentication logic.
Render a form with input fields for the username and password, and a submit button. Use the onChange event to update the component's state with the user input.

This is a basic implementation of a login page in React. You can add more features, such as validation and error handling, to make your login page more robust.
