Project Overview

A Dockerized ecommerce backend system built using a microservices architecture. It uses an API Gateway as the single entry point for all incoming client requests, forwarding them to independent services: Auth Service, Product Service, and Order Service. This project was created to move beyond traditional monolithic CRUD applications and understand scalable backend systems in production-style environments.

Target Audience

Developers and software engineers interested in microservices architecture, API gateways, and scalable backend design.

Business Goal

To build a robust, scalable backend system demonstrating microservices separation, JWT authentication flows, service-to-service communication, and Dockerized deployment.

Key Features

🚪

API Gateway Pattern

Central entry point for all incoming client requests, handling request forwarding, route management, and authorization header forwarding.

🔐

Advanced Authentication

Secure JWT-based authentication using Access and Refresh tokens with role-based access control (RBAC) for route protection.

📦

Product & Order Services

Independent services for handling product catalogs and order processing, demonstrating service-to-service communication using Axios.

🛡️

Robust Validation

Comprehensive request validation across all services using Zod for schemas, ensuring clean request handling and early error detection.

🐳

Dockerized Architecture

Complete system containerized using Docker Compose, including API Gateway, independent services, and MongoDB.

⚠️

Centralized Error Handling

Consistent API error responses and async error management implemented across all microservices.

📚

Interactive Documentation

Integrated Swagger/OpenAPI documentation for all APIs, enabling interactive testing and easier integration.
