How To Link Login Page To Homepage In React Js

Web Development Software

If you’re a React JS developer like me, you know how important it is to create a seamless user experience in your web applications. One crucial aspect of this is linking the login page to the homepage. In this article, I will guide you through the process of linking the login page to the homepage in React JS, and also provide some personal touches and commentary along the way!

Setting up the Login Page

Before we can link the login page to the homepage, we need to set up the login page itself. In React JS, we typically create separate components for each page of our application. To create the login page component, we can start by creating a new file called LoginPage.js.

Inside the LoginPage.js file, we will write the code for our login page component. This component will include a form where the user can enter their username and password, and a submit button to authenticate their credentials. You can add your personal touches to the design and layout of the login page component to make it unique to your application.

Note: It’s essential to handle form validations and submit functionality in your login page component. For the sake of simplicity, I won’t go into the details of validation and API calls in this article, but feel free to add those features to enhance the login functionality.

Creating the Homepage

Now that we have our login page set up, we can move on to creating the homepage component. In React JS, the homepage is often referred to as the main component, which is rendered when the user successfully logs in.

Create a new file called HomePage.js and define the code for your homepage component inside it. This component can include various sections and elements, depending on the requirements of your application. You can add personal touches and commentary to make the homepage visually appealing and user-friendly.

Linking the Login Page to the Homepage

Now comes the exciting part – linking the login page to the homepage! To achieve this, we need to implement a routing system in our React JS application. The most popular library for routing in React JS is react-router-dom.

If you haven’t already installed react-router-dom, you can do so by running the following command in your project’s root directory:

npm install react-router-dom

Once react-router-dom is installed, we can import the necessary components and set up the routes in the main file of our application, typically App.js.

First, import the necessary components:

{`import { BrowserRouter as Router, Route, Switch, Link, Redirect } from 'react-router-dom';`}

Next, set up the routes:

{`function App() {
return (


In the code above, we have defined two routes: one for the login page (path=”/”) and another for the homepage (path=”/home”). The exact keyword ensures that the login page component is rendered only when the URL path exactly matches “/”.

To handle the case when the user successfully logs in, we can create a higher-order component called PrivateRoute. This component checks whether the user is authenticated and redirects them to the homepage if they are, or to the login page if they’re not.

{`function PrivateRoute({ component: Component, }) {
const isAuthenticated = // Add your logic to check if the user is authenticated
return (

isAuthenticated ? (

) : (


Now, when the user enters their credentials and clicks the submit button on the login page, you can handle the authentication logic and redirect them to the homepage by using the history.push() method:

{`import { useHistory } from 'react-router-dom';

function LoginPage() {
const history = useHistory();

const handleLogin = () => {
// Add your authentication logic here

// Redirect to the homepage

// Rest of the login page component code


In this article, we’ve explored the process of linking the login page to the homepage in React JS. We started by setting up the login page component, followed by creating the homepage component. Finally, we implemented routing using react-router-dom to link the login page to the homepage.

Remember, the design and functionality of your login page and homepage can vary depending on your application’s requirements. Feel free to add your personal touches and commentary to make the user experience unique and enjoyable.

Now that you have a solid understanding of how to link the login page to the homepage in React JS, go ahead and implement this feature in your own projects. Happy coding!

Note: The code examples provided in this article are simplified for demonstration purposes. Make sure to handle form validations, API calls, and other necessary steps according to your application’s requirements.
