How To Create Login Page In React

How To Articles

In this article, I will guide you through the process of creating a login page in React. As a developer who has worked extensively with React, I can attest to its simplicity and flexibility when it comes to building user interfaces and handling user interactions.

Getting Started

The first step is to set up a new React project. If you haven’t already installed Node.js and npm, make sure to do so before proceeding. Once you have them installed, open your terminal and run the following command:

npx create-react-app login-page

This command will create a new directory called “login-page” and set up a basic React project structure inside it. Navigate to the project directory by running:

cd login-page

Next, you’ll need to install a few additional dependencies. Run the following command:

npm install react-router-dom axios

We will be using react-router-dom for routing and axios for making HTTP requests to a server. These libraries will be essential for implementing the login functionality.

Creating the Login Form

Now that we have our project set up, let’s start by creating the login form component. Inside the “src” directory, create a new file called “LoginForm.js”. Open the file and add the following code:

{`import React, { useState } from 'react';
import axios from 'axios';

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

const handleLogin = async (e) => {
try {
const response = await'/api/login', { username, password });
// Redirect to the dashboard page
// window.location.href = '/dashboard';
} catch (error) {
// Display error message to the user

return (



export default LoginForm;`}

In this code, we define a functional component called “LoginForm”, which contains two state variables: “username” and “password”. The form fields are bound to these variables and updated whenever the user types into the fields.

When the form is submitted, the “handleLogin” function is called. This function makes a POST request to a login endpoint (replace ‘/api/login’ with the actual URL of your server’s login endpoint). If the login is successful, the response is logged to the console, and the user is redirected to the dashboard page.


Now that we have our login form, we need to set up routing so that we can navigate to the login page. Inside the “src” directory, create a new file called “App.js”. Open the file and replace its contents with the following code:

{`import React from 'react';
import { BrowserRouter as Router, Switch, Route } from 'react-router-dom';
import LoginForm from './LoginForm';

const App = () => {
return (


export default App;`}

In this code, we import the necessary components from react-router-dom and define a functional component called “App”. Inside the component, we set up a router using the BrowserRouter component and define a single route for the login page.


Congratulations! You have successfully created a login page in React. This article covered the process of setting up a new React project, creating a login form component, and setting up routing for the login page. Remember to replace the placeholder URLs with actual endpoints from your server and customize the login form according to your requirements. Happy coding!
