Project Overview

Purpose

This project consists of three microservices (user-service, product-service, and order-service) that manage user registration, product inventory, and order placement. The services communicate asynchronously using RabbitMQ for event-driven architecture and use PostgreSQL for data persistence.

Key Features

• Microservices: Independent services for users, products, and orders.
• Asynchronous Communication: RabbitMQ for event-driven message passing.
• Data Persistence: PostgreSQL with migrations handled via Golang's sqlx.
• Caching: Redis is used for caching to improve read performance.
• Authentication: JWT-based authentication in the user-service.

Technologies

• Golang (Fiber Framework)
• PostgreSQL
• RabbitMQ
• Redis
• Docker (for containerization)
• gqlgen (for the GraphQL API gateway)
