This tutorial demonstrates how to integrate Descope authentication into a web application featuring a React frontend and a Flask backend. It guides users through setting up a multi-page app with home, login, and profile pages, along with protected routes, by using Descope's authentication services. The React part involves wrapping the app with an AuthProvider and configuring routes, while the login page checks authentication status using Descope's libraries. The profile page fetches roles and secret messages from the Flask backend, which includes setting up a Descope client and creating a token_required decorator to secure endpoints. By validating user roles, the app displays different dashboards based on user roles like teacher or student. This hands-on approach with code snippets and step-by-step instructions aims to help developers implement robust authentication in their applications, encouraging them to explore further customization and join the AuthTown community for additional support.
