E-Commerce Backend (Node.js)

Production-oriented backend architecture designed for scalability, security, and maintainability.

Usage

Install

npx @amt9x/backend-generator project-name

or

npm i @amt9x/backend-generator

Project Goal

This project demonstrates how a modern backend system is structured in real-world production environments.

Focus areas:

• Clean Architecture principles
• Modular monolith design
• Security-first backend mindset
• Scalability & reliability foundations
• Interview-ready System Design showcase

Design Principles

• Modular Monolith
• Domain-driven folder structure
• Dependency direction: Interface → Core → Infrastructure
• Separation of concerns

Tech Stack

• Node.js
• TypeScript
• Docker-ready
• CLI scaffolding automation

Modules

Module	    Responsibility
---------------------------------------------
auth        authentication & authorization
---------------------------------------------
user        user management
---------------------------------------------
product     product catalog
---------------------------------------------
order       order lifecycle
---------------------------------------------
payment     payment processing

Security Mindset

• Centralized error handling
• Security layer isolation
• Middleware-based protection
• OWASP-aware design

Scalability Strategy

• Stateless API design
• Queue-ready architecture
• Cache layer abstraction
• Worker-based async processing

Project Bootstrap

Backend structure can be generated via CLI:

npx create-backend

Testing Strategy

• Unit tests
• Integration tests
• Future E2E support

Docker Support

Container-ready structure prepared for production deployment.

Future Improvements

• Redis caching
• Message queue integration
• Observability (metrics + tracing)
• CI/CD pipeline
