🛠️ Architecture

Diagram

Description

The application follows a modern and decoupled architecture:

1. Client App:
   • Web interface built with Next.js.
2. Backend:
   • Gateway for orchestration and security.
   • BFF (Backend for Frontend):
     • Built using Server Side Actions of Next.js to handle server-side data processing and streamline client interactions.
   • Specialized, independent services:
     • Identity-svc: User management and authentication.
     • Auction-svc: Auction control.
     • Search-svc: Catalog searches.
     • Bidding-svc: Bid management.
     • Notification-svc: Real-time notifications.
3. Event Bus:
   • Implemented with RabbitMQ and orchestrated using MassTransit to enable Publish/Subscribe messaging for asynchronous communication between services.
4. Databases:
   • PostgreSQL: For transactional services.
   • MongoDB: For flexible data and fast queries.
