📌 Project Summary – Node.js Layered Monorepo Architecture

This project demonstrates a scalable Node.js + TypeScript monorepo setup following a layered architecture pattern. It is designed to help developers build large, maintainable, and testable backend systems.

🔑 Key Highlights
🔧 Monorepo Structure – Organizes multiple applications (e.g., orders, users, etc.) in one repository with isolated domains.
- Layered Architecture – Each application is divided into three layers:
1. API (entry-points): Express routes, controllers, middleware.
2. Domain: Core business logic, entities, DTOs, validation.
3. Data Access: Database repositories (MongoDB/Mongoose).

🔧 Shared Libraries – Common functionality like logging, error handling, authentication, and validation.

🔧 TypeScript Best Practices – Strong typing, strict mode, and maintainable code structure.

🔧 Security & Stability – Includes JWT authentication, Helmet, rate-limiting, and centralized logging with Pino.

🔧 Environment Validation – Uses Zod to ensure reliable configuration management.

🎯 Purpose
The goal of this project is to provide a blueprint for building enterprise-grade Node.js applications with clear separation of concerns, high scalability, and maintainability.

🚀 Get Started
Clone the repo, explore the codebase, and use it as a reference for your own projects or as a learning resource for understanding modern backend architecture.

🚀 What is REST (Representational State Transfer)?

If you’re getting into APIs, REST is probably the first architecture you’ll hear about. It’s the most widely used approach to building web APIs today. Here’s why:
🔹 Style: Resource-based
🔹 Data Format: Usually JSON or XML
🔹 Characteristics:

Stateless communication (each request is independent)

Uses standard HTTP methods like GET, POST, PUT, DELETE, PATCH

Easy to implement and widely adopted

💡 Use cases: REST is perfect for web apps, mobile apps, and CRUD operations where you need simple, reliable communication between client and server.
Think of it as the “universal language” of APIs easy to learn, easy to use, and flexible enough for most projects.

💡 What is SOAP (Simple Object Access Protocol)?

SOAP is one of the oldest but still powerful API architectures. Unlike REST, it’s more rigid, but it brings strong standards and security to the table.

🔹 Style: Protocol-based
🔹 Data Format: XML
🔹 Characteristics

Highly standardized with WSDL (Web Services Description Language)
Strong security with WS-Security
Heavier compared to REST, but ensures strict contracts

💼 Use cases: SOAP is still widely used in banking, enterprise systems, and legacy integrations, where strict rules and high security are a must.
Think of SOAP as the “formal suit and tie” of APIs strict, secure, and serious about business. 👔
