MallChat is an enterprise-grade e-commerce system that integrates instant messaging (IM) capabilities, allowing users to shop and chat simultaneously. It aims to provide a best-practice example for internet-scale development, covering essential e-commerce features like shopping carts, orders, payments, recommendations, search, and customer service, alongside robust IM functionalities.

How It Works

The backend utilizes Netty for WebSocket connections, enabling real-time communication with the frontend. It incorporates features like WeChat scanning for login, member and message lists, message interactions, and rich message types. Utility components include AOP logging, distributed locks, rate limiting annotations, and IP-based geolocation. The architecture emphasizes enterprise-level development standards.
