Node.js Fundamentals

Description

This repository contains solutions for Node.js Fundamentals assignment. The assignment covers various Node.js core APIs including File System, CLI, Modules, Hash, Streams, Zlib, Worker Threads, and Child Processes.

Getting Started

1. Fork this repository

   Click the "Fork" button at the top right of this page: https://github.com/AlreadyBored/node-nodejs-fundamentals

2. Clone your fork

   git clone https://github.com/YOUR_USERNAME/node-nodejs-fundamentals.git
   cd node-nodejs-fundamentals

3. Install dependencies (if any added in the future)

   npm install

4. Start implementing the tasks

   Each file in the src/ directory contains a function template with comments describing what needs to be implemented.

Requirements

• Node.js version: >=24.10.0
• npm version: >=10.9.2
• No external libraries allowed

Usage

File System (src/fs)

• npm run fs:snapshot - Create snapshot of workspace directory
• npm run fs:restore - Restore directory structure from snapshot
• npm run fs:findByExt - Find files by extension in workspace
• npm run fs:merge - Merge .txt files from workspace/parts
• npm run fs:merge -- --files a.txt,b.txt,c.txt - Merge specific files from workspace/parts in provided order

Snapshot format reminder:

{
  "rootPath": "/absolute/path/to/workspace",
  "entries": [
    { "path": "file1.txt", "type": "file", "size": 1024, "content": "base64" },
    { "path": "nested", "type": "directory" }
  ]
}

entries[].path values must be relative to workspace.

CLI (src/cli)

• npm run cli:interactive - Interactive command-line interface
• npm run cli:progress - Display progress bar

Modules (src/modules)

• npm run modules:dynamic - Dynamic plugin loading

Hash (src/hash)

• npm run hash:verify - Verify file checksums using SHA256

Streams (src/streams)

• npm run streams:lineNumberer - Add line numbers to stdin input
• npm run streams:filter - Filter stdin lines by pattern
• npm run streams:split - Split file into chunks

Zlib (src/zip)

• npm run zip:compressDir - Compress directory to .br archive
• npm run zip:decompressDir - Decompress .br archive

Worker Threads (src/wt)

• npm run wt:main - Parallel sorting with worker threads

Child Processes (src/cp)

• npm run cp:execCommand - Execute command in child process
