Integrating Azure AD B2C with React using msal-react

The msal-react library provides a convenient way to integrate Azure AD B2C with React applications. Here’s a step-by-step guide to get you started:

Step 1: Register Your Application

First, register your React application with Azure AD B2C:

az b2c app create --resource-group <resource-group> --name <app-name> --reply-urls <reply-url>

Step 2: Install msal-react

Next, install the msal-react library using npm or yarn:

npm install @azure/msal-react

Step 3: Configure msal-react

Configure msal-react by creating a new instance of the PublicClientApplication class:

import { PublicClientApplication } from '@azure/msal-react';

const clientApp = new PublicClientApplication(
  '',
  '',
  ''
);

Step 4: Add Authentication to Your React App

Finally, add authentication to your React app by wrapping your components with the AuthProvider component:

import { AuthProvider } from '@azure/msal-react';

function App() {
  return (
    <AuthProvider clientApp={clientApp}>
      <YourAppComponents />
    </AuthProvider>
  );
}

That’s it! With these steps, you’ve successfully integrated Azure AD B2C with your React application using msal-react.

Conclusion

Azure AD B2C provides a robust and scalable platform for managing user identities, and integrating it with React using msal-react is a straightforward process. By following this guide, you can ensure secure and seamless authentication for your users.
