Node.js File Processor

A practical Node.js file processing application built using Node.js built-in modules.

The project focuses on working with files, directories, streams, buffers, cryptographic operations, and operating system functionality without relying heavily on external packages.

🎯 Project Goals

The main goals of this project are to:

• Practice Node.js core modules
• Work with synchronous and asynchronous file operations
• Process files efficiently using streams
• Work with buffers and binary data
• Perform cryptographic operations
• Manipulate file and directory paths
• Access operating system information
• Understand how Node.js handles file processing internally

🛠️ Technologies

• Node.js
• JavaScript
• Node.js Core Modules
• npm
• Git & GitHub

Core Modules

The project uses modules such as:

• fs
• fs/promises
• path
• crypto
• os
• http
• stream

🚀 Getting Started

Clone the repository:

git clone https://github.com/MIhajloS07/nodejs-file-processor.git

Navigate to the project directory:

cd nodejs-file-processor

Install dependencies:

npm install

Run the application:

node server.js

🔍 What the Project Demonstrates

File System Operations

Using Node.js fs and fs/promises to:

• Read files
• Write files
• Create and manage files
• Work with asynchronous file operations

Path Handling

Using the path module to work with:

• File extensions
• File names
• Directory paths
• Absolute and relative paths

Streams

Using streams to process data in chunks instead of loading an entire file into memory at once.

This makes streams useful when working with large files.

Buffers

Using Buffer to work with binary data and understand how Node.js handles data at a lower level.

Cryptography

Using Node.js crypto functionality for operations such as:

• Hashing
• HMAC
• Encryption
• Decryption

Operating System Information

Using the os module to retrieve information about the environment in which the application is running.

📚 Learning Focus

This project is part of my practical exploration of the Node.js runtime and its built-in APIs.

Instead of relying entirely on external npm packages, the project intentionally uses Node.js core modules to understand the functionality provided directly by the runtime.

🔄 Project Status

🚧 In development

The project is continuously being expanded with additional file-processing functionality and deeper exploration of Node.js APIs.
