Todo Gateway (BFF Pattern)

• This project demonstrates a Backend-for-Frontend (BFF) pattern using Spring Boot 6 + Spring Security 6 + Keycloak + WebFlux Gateway.
• The Gateway acts as the login entry point, handles security, and proxies requests to the Todo Service.

Features

• Gateway as Login Point (/oauth2/authorization/keycloak)
• Session-based token handling
• Routes requests to Todo Service (/todos/**)
• Simple HTML UI (index.html) for manual testing

Authentication Flow

• User clicks Login → redirected to Keycloak login page.
• After successful login → session created at Gateway.
• Requests to /todos/** are automatically forwarded with the token.
• User can Logout at /logout.

HTML Test Page

• Open http://localhost:8080/index.html

Features

• Login / Logout buttons
• Paginated Todo table (with Edit/Delete actions)
• Create new todo

Configuration

Update postgres db and oauth2 authorization server information in application.properties files of gateway and todo app.
