  • User authentication is a crucial aspect of any web application. It ensures that only authorized users can access sensitive information or perform certain actions within the application. With the rise of single-page applications and React’s popularity as a frontend library, implementing user authentication in a React application is essential.
  • In this blog post, we’ll explore how to implement user authentication in a React application with Asgardeo, a secure, cloud-native identity and access management solution. Asgardeo provides easy-to-use components and APIs that make implementing user authentication a breeze. We’ll walk through each step of the process, from creating a new React application to protecting routes and accessing user information with the Asgardeo Auth context. So, let’s dive in and learn how to implement user authentication in your React application with Asgardeo.

Step 1 — Create React Application

  • To start, create a new React application by using create-react-app or any other tool of your choice.

Step 2 — Install Asgardeo:

  • Next, install Asgardeo and its dependencies. You can do this by running the following command in your project directory:
npm install @asgardeo/auth-react

Step 3 — Initialize Asgardeo

const authConfig = {
signInRedirectURL: "http://localhost:3000/home",
signOutRedirectURL: "http://localhost:3000/",
clientID: "<your_client_id>",
serverOrigin: "<your_server_origin>",
scopes: ["openid", "profile", "email"],
};

export default authConfig;
  • In this configuration file, you need to replace the values of clientID and serverOrigin with the values provided by Asgardeo when you registered your application.

Step 4 — Add Authentication Routes:

  • To use Asgardeo for authentication, you need to add authentication routes to your application. You can do this by adding the following code to your App.js file:
import { SignIn } from "@asgardeo/auth-react";

function App() {
return (
<div className="App">
<header className="App-header">
<SignIn />
</header>
</div>
);
}

export default App;

Step 5 — Use the Auth context:

  • To access the authentication state and user information throughout your application, you need to use the Auth context provided by Asgardeo. You can do this by adding the following code to your App.js file:
import { AuthProvider } from "@asgardeo/auth-react";
import authConfig from "./asgardeo.config";

function App() {
return (
<div className="App">
<header className="App-header">
<AuthProvider config={authConfig}>
{/* Your application code goes here */}
</AuthProvider>
</header>
</div>
);
}

export default App;

Step 6 — Protect Routes

  • To protect routes in your application, you need to use the ProtectedRoute component provided by Asgardeo. You can do this by adding the following code to your App.js file:
import { ProtectedRoute } from "@asgardeo/auth-react";

function App() {
return (
<div className="App">
<header className="App-header">
<AuthProvider config={authConfig}>
<ProtectedRoute path="/home">
{/* Your protected route code goes here */}
</ProtectedRoute>
</AuthProvider>
</header>
</div>
);
}

export default App;
  • In this example, the route /home is protected and can only be accessed by authenticated users. If a user is not authenticated, they will be redirected to the sign-in page.
  • To sum up, implementing user authentication in a React application is crucial to ensure the security and privacy of users’ sensitive information. With Asgardeo, it’s easy to implement user authentication in a React application, and it provides a cloud-native, secure identity and access management solution that’s easy to use.
  • In this blog post, we’ve covered the steps to implement user authentication in a React application with Asgardeo. We started with creating a new React application, installing Asgardeo, initializing it, adding authentication routes, using the Auth context, and protecting routes. By following these steps, you can implement user authentication in your React application with ease.
  • I hope this blog post has been helpful in guiding you through the process of implementing user authentication in a React application with Asgardeo. With Asgardeo, you can ensure the security and privacy of your users’ sensitive information, and provide a seamless and secure authentication experience.
