Shipr 🚢

Shipr is a personal project aimed at helping folks understand distributed microservice architecture. It’s a simple, lightweight system designed to manage products, process orders, and handle payments.

Shipr inventory service 📦

The Inventory Service is the backbone of Shipr's infrastructure, responsible for tracking product availability and stock management.

• Main Application (main.py): The core of the inventory service, powered by FastAPI. It exposes RESTful APIs for CRUD oeprations.

• Consumer (consumer.py): In conjunction with the main service, the consumer listens to Redis streams for updates on completed orders. When an order is processed, it adjusts inventory levels in real-time, ensuring that stock data is always accurate. In the event of an error, it triggers a refund process to maintain data integrity and customer satisfaction.
