This project demonstrates a simple microservices architecture with Golang, FastAPI, Flask, and Node.js.
Each service handles different aspects of an e-commerce system and communicates via REST APIs.
The entire system runs with Docker Compose.
| Service | Technology | Port | Description |
|---|---|---|---|
| API Gateway | Golang (Gin) | 5000 |
Routes requests & aggregates data |
| User Service | Golang (Gin) | 5001 |
Handles user details |
| Order Service | FastAPI | 5002 |
Handles order details |
| Payment Service | Flask | 5003 |
Handles payment details |
| Product Service | Node.js (Express) | 5004 |
