📂 Folder & File Explanations

1️⃣ config/

Stores configuration files for external services or database connections.

• mongoose.js → Initializes and configures MongoDB using Mongoose.

2️⃣ controllers/

Contains route handlers that process requests and return responses.

• user.controller.js → Manages user-related logic (e.g., register, login, CRUD).

3️⃣ models/

Defines database schemas and models using Mongoose.

• user.model.js → Defines the User schema with fields like name, email, password.

4️⃣ routes/v1/

Defines API routes and maps them to controllers.

• routes.js → Centralized API routing for version 1 (v1).

5️⃣ services/user/

Contains business logic and reusable service functions.

• auth.service.js → Handles authentication logic (e.g., password hashing, token generation).
• user.service.js → Handles user-related operations (e.g., CRUD, profile updates).

6️⃣ utils/

Utility functions for handling errors, memory monitoring, and sockets.

• error.handler.js → Centralized error handling middleware.
• memory.handler.js → Monitors memory usage and prevents leaks.
• socket.handler.js → Handles WebSocket (socket.io) connections.

7️⃣ validations/user/

Handles request validations using libraries like Joi or Express Validator.

• auth.validation.js → Validates authentication-related requests (e.g., login, register).
• user.validation.js → Validates user data inputs for CRUD operations.

8️⃣ Root Files

• .env → Stores environment variables (e.g., database URL, API keys).
• .env.example → Example .env file for developers.
• .gitignore → Prevents unnecessary files from being committed.
• index.js → Entry point of the application, initializes Express server.
• package.json → Lists dependencies, scripts, and project metadata.
• README.md → Documentation for the project.

Environment Configuration Guide

This document provides instructions on how to set up and configure the environment variables for the application.

Prerequisites

• Ensure you have Node.js installed on your system.
• A .env file should be created in the root directory of the project.
• Do not expose sensitive credentials in public repositories.

Setup Instructions

1. Create a .env file in the root directory of the project if it does not already exist.

2. Copy the following template into your .env file and update the values accordingly:

# Node.js environment setting
NODE_ENV=development

# Application server port
PORT=3000

# Application name
APP_NAME="YourAppName"

# Base URL of the application
APP_URL="http://localhost:3000"

# MongoDB connection string
MONGODB_URL="mongodb://localhost:27017/mydatabase"

# Secret key for encryption/decryption
SECRET_KEY="SECRET_KEY_FOR_ENCRYPTION_AND_DECRYPTION"

# JWT secret key for authentication
JWT_SECRET="JWT_SECRET_KEY"

# Whitelisted domains for CORS (comma-separated values)
WHITE_LISTED_DOMAINS="http://localhost:4200, http://localhost:3000"

# SMTP email configurations
SMTP_HOST=smtp.zoho.com  
SMTP_PORT=465  
SMTP_USERNAME[email protected]  
SMTP_PASSWORD=appPassword  
EMAIL_FROM[email protected]  

Notes:

• Update all values as per your environment.
• Use strong and unique keys for SECRET_KEY and JWT_SECRET.
• For production, avoid hardcoding secrets; use a secure vault or environment variable manager.
• Ensure the .env file is added to .gitignore to prevent exposing sensitive information.

Security Considerations

• Never commit the .env file to version control.
• Use environment variable management tools like dotenv, AWS Secrets Manager, or Vault for production setups.
• Regularly rotate your secret keys and credentials.
