# Node.js Core Modules Practice

Welcome to the **Node.js Core Modules** repository! This project serves as a practical hands-on demonstration of Node.js built-in modules. It is intended for beginners, students, and developers who want to understand how to work with the most commonly used core modules in Node.js without external dependencies.

## 🧠 Project Objective

This project aims to provide a clear and concise understanding of:

- What Node.js core modules are
- How to use them in real applications
- Practical examples using each module in a simple and straightforward manner

## 🚀 Getting Started

### 1. Clone the Repository

```npm
git clone https://github.com/officialTechBro/nodejs_core.git
cd nodejs_core

2. Run a Module

Each module can be executed independently using Node.js:

node fsModule.js

To run the HTTP server:

node server.js

📚 Core Modules Demonstrated

Module	Description
fs	File system interactions (read/write files)
os	System-level information (CPU, memory, uptime)
path	File and directory path handling
crypto	Hashing and encryption operations
events	Event-driven architecture with custom emitters
url	URL parsing and formatting
process	Access and control of the current process
http	Building a simple web server

---

🌐 Server Details

The server.js script spins up a basic HTTP server and routes incoming requests to different handlers based on the URL and HTTP method. The postController.js handles logic for POST requests specifically.

---

🛠️ Requirements

• Node.js v14+ recommended
• No external dependencies are required

---

✅ Future Improvements

• Add Express.js examples alongside core HTTP module
• Add a frontend interface to interact with the server
• Unit tests for each module demonstration
• Add comments and documentation in code
