Login form in React JS 2025

Login Form in React JS 2025

📘 What is it?

A login form in React helps you capture and handle user credentials like email and password. It is commonly implemented using the useState hook to manage form input and basic validation.

🧠 Key Concepts:

  • Using useState for controlled inputs
  • Handling form submission with onSubmit
  • Simple validation before submission

⚙️ Example Code:


import React, { useState } from 'react';

function LoginForm() {
  const [form, setForm] = useState({ email: '', password: '' });

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

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log('Login submitted:', form);
    // Add real auth logic here
  };

  return (
    

      

        
        
      


      

        
        
      


      
    

  );
}

export default LoginForm;

🎯 Tips:

  • Always validate inputs before submitting.
  • Use backend API to verify credentials.
  • Don't forget to handle error messages and loading states.
