Repository for Study Purposes

This repository is created for studying and practicing Layered Architecture with Node.js and TypeScript.

Layered Architecture: Concepts and Detailed Explanation

A Layered Architecture separates an application into distinct layers, each with a specific responsibility. This modular design simplifies maintenance, testing, and scaling of the codebase.

Common Layers in a Node.js + TypeScript Application

1. Presentation Layer

   • Handles user input and interactions (e.g., REST APIs, UI components).

2. Service Layer

   • Contains business logic and orchestrates operations.

3. Repository Layer

   • Interacts with the database for fetching and storing data.

4. Model Layer

   • Defines the structure of the data (schemas and types).

Benefits of a Layered Architecture

1. Separation of Concerns
   Each layer has a clear and specific role, leading to better organization.

2. Reusability
   Business logic in the Service Layer can be reused across multiple interfaces (e.g., APIs, CLI tools).

3. Testability
   Each layer can be tested in isolation (e.g., unit testing services or repositories).

4. Scalability
   Adding new features or interfaces becomes easier due to the decoupled nature of the layers.

Learning Goals

• Practice building applications using Node.js and TypeScript.
• Understand the principles and benefits of Layered Architecture.
• Gain hands-on experience in structuring code for maintainability and scalability.

---

Each folder has a specific role in implementing the Layered Architecture:

• app.ts: Entry point of the application. Initializes and configures the app.
• models/: Contains data models and schemas for defining data structure.
• repositories/: Manages data access logic, interacting with the database.
• services/: Implements the core business logic of the application.
• controllers/: Handles incoming API requests and responses.
• routes/: Defines API routes and maps them to corresponding controllers.
• utils/: Holds reusable utility functions.
