React User Authentication with Clerk
React is a popular JavaScript library for building user interfaces, and one common scenario in web development is implementing user authentication. Clerk is a powerful authentication and user management system that simplifies the process of adding authentication to your React application.
In this tutorial, we will walk through how to set up user authentication with Clerk in your React application in just 10 minutes.
Step 1: Install Clerk SDK
First, you need to install the Clerk SDK in your React application. You can do this by running the following command in your terminal:
npm install @clerk/clerk-react
Step 2: Set up Clerk Provider
Next, you need to set up the Clerk provider in your React application. Add the following code to your index.js file:
import React from 'react';
import ReactDOM from 'react-dom';
import { ClerkProvider } from '@clerk/clerk-react';
ReactDOM.render(
,
document.getElementById('root')
);
Replace YOUR_FRONTEND_API_KEY with your Clerk frontend API key, which you can find in the Clerk dashboard.
Step 3: Set up Sign-in Component
Now, you can set up a sign-in component in your React application. Here is an example of a simple sign-in component:
import React from 'react';
import { SignIn } from '@clerk/clerk-react';
function SignInPage() {
return (
Sign In
);
}
export default SignInPage;
You can then use this component in your application to allow users to sign in.
Step 4: Protect Routes
Finally, you can protect routes in your application by checking if the user is authenticated. Clerk provides a convenient way to do this using the useUser hook. Here is an example:
import React from 'react';
import { useUser } from '@clerk/clerk-react';
function PrivateRoute({ children }) {
const { user } = useUser();
if (user) {
return children;
} else {
return ;
}
}
export default PrivateRoute;
You can then use this PrivateRoute component to protect routes in your application that require authentication.
That’s it! You have now successfully set up user authentication with Clerk in your React application. With just a few simple steps, you can ensure that only authenticated users can access certain parts of your application. Happy coding!

virus detected on powershell? what the hell with that code bro
Thank You! Bro! this has really helped me, but change your name to something more search friendly because i searched and searched you after i changed computers but could not find you, i have now subscribed!
Hlo ,
it is great demo ,but they show error process is not defined
Thank you dude, help me a lot with my final paper
this is great, thank you!
i loved this demo. Congrats!!
I think it would have been even nicer if you had added a section to the video showing how to retrieve user information and sending it to a server.
i Got this error in the console
No routes matched location "/signin"
How do we customise the inside parts of the component? And also mine keeeps redirecting to a weird url whenever I logout idk whats wrong.
Great demo, and super neat tool. Should make my React projects a lot simpler. Thanks for the walkthrough.
