React/Python + Chalice Starter App

A tutorial demonstrates how to build a React-based B2B application with PropelAuth for hosted authentication and account management, alongside a Python backend deployed through AWS Chalice. It covers configuring a PropelAuth project and branded login pages, creating test users, integrating the React AuthProvider and routing, handling login, signup, logout, protected pages, and displaying authenticated user information. The frontend sends bearer access tokens to protected backend endpoints, with a development proxy used to address local CORS concerns. On the backend, the PropelAuth Python library validates JWT access tokens and returns appropriate authorization responses, while Chalice packages and deploys the service as AWS Lambda functions. The application is extended with organization capabilities, allowing users to list their organizations, create one or accept invitations when none exist, and retrieve organization details only when membership authorization is confirmed.
