React Router Login Page

I’ve been working with React for a while now, and one of the most common challenges I’ve faced is implementing a login page using React Router. In this article, I’ll share my experiences and insights on how to create a login page with React Router. So, grab a cup of coffee and let’s dive into the world of routing and authentication in React!

The Power of React Router

If you’re new to React, you might be wondering what React Router is and why it’s so important. Well, React Router is a popular routing library for React applications. It allows us to define different routes and navigate between them without refreshing the page.

One of the key features of React Router is its ability to handle authentication and protected routes. With React Router, we can easily create a login page and ensure that only authenticated users can access certain routes. This is a crucial aspect of any modern web application that deals with user authentication and authorization.

Creating the Login Page

Let’s start by creating the login page itself. We’ll need a form with input fields for the user’s email and password, as well as a submit button. Here’s an example:

<label htmlFor="email">Email:</label>
<input type="email" id="email" />
<br />
<label htmlFor="password">Password:</label>
<input type="password" id="password" />
<br />
<button type="submit">Login</button>

Once the user submits the login form, we’ll need to handle the form submission and authenticate the user. This is where React Router comes into play. We can define a route for the login page and specify a callback function that handles the form submission. Here’s an example:

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

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

const handleFormSubmit = (event) => {
// Perform authentication logic here

// Redirect the user to a protected route

return (
<form onSubmit={handleFormSubmit}>
{/* Form fields */}

As you can see, we’re using the useHistory hook from React Router to get access to the history object. We then use the history.push() method to redirect the user to the dashboard route, assuming the authentication is successful.

Protecting Routes

Now that we have a login page, we need to make sure that only authenticated users can access certain routes. To accomplish this, we can use a combination of React Router and a higher-order component (HOC) called privateRoute.

The privateRoute HOC is responsible for checking if the user is authenticated. If the user is authenticated, it renders the requested component. Otherwise, it redirects the user to the login page. Here’s an example implementation:

import { Redirect, Route } from 'react-router-dom';

function privateRoute({ component: Component, }) {
const isAuthenticated = // Check if user is authenticated

return (
render={props =>
isAuthenticated ? (
<Component {...props} />
) : (
<Redirect to="/login" />

// Usage:
<privateRoute path="/dashboard" component={Dashboard} />

With the privateRoute HOC in place, we can easily protect any route by wrapping it with the privateRoute component. If the user is not authenticated, they will be redirected to the login page.


Implementing a login page with React Router is a crucial step in any web application that requires user authentication. By leveraging the power of React Router, we can easily create a login page, handle form submissions, and protect routes from unauthorized access.

In this article, we explored the basics of creating a login page using React Router. We discussed how to handle form submissions, redirect users to protected routes, and protect routes using the privateRoute HOC. I hope you found this article helpful and that it provides a solid foundation for implementing a login page with React Router in your own projects.

Now, it’s time to take what you’ve learned and start building your own login page using React Router. Happy coding!
