Build A Login Page With React

How To Articles

Welcome to my new blog post about building a login page with React! As a developer, I often find myself working on user authentication and login functionality. In this article, I will guide you through the process of creating a login page using React, a popular JavaScript library for building user interfaces.

Why React?

React is widely known for its simplicity and efficiency in building interactive web applications. It provides a component-based architecture, which allows us to break down our UI into reusable and modular pieces. This makes it easy to manage the login page and other components throughout the application.

Setting Up the Project

Before we start coding, let’s make sure we have a React project set up. If you haven’t done so already, you can create a new React project using create-react-app:

npx create-react-app login-page

Once the project is set up, navigate to the project directory:

cd login-page

Now we are ready to start building our login page!

Creating the Login Component

The first step is to create a new component for our login page. In the src directory, create a new file called Login.js and add the following code:

import React, { useState } from 'react';

const Login = () => {
const [username, setUsername] = useState('');
const [password, setPassword] = useState('');

const handleLogin = () => {
// Add login logic here

return (





export default Login;

In the code above, we are using the useState hook to manage the state of the username and password fields. When the user enters their credentials and clicks the login button, the handleLogin function will be called, and you can add your own login logic there.

Using the Login Component

Now that we have our login component ready, we can use it in our main App component. Open the App.js file in the src directory and replace its contents with the following code:

import React from 'react';
import Login from './Login';

const App = () => {
return (

Welcome to My Login Page


export default App;

Save the file and start the development server using the following command:

npm start

Now you can open your browser and navigate to http://localhost:3000 to see your login page in action!


In this article, we learned how to build a login page with React. React’s component-based approach allows us to easily create modular and reusable UI components, making it a great choice for building user interfaces.

Remember, this login page is just a starting point. You can add more features like form validation, authentication, and error handling to make it more robust and secure. Happy coding!
