🕵️ NodeSnitch

A simple Java tool to find and analyze node_modules directories in your system, demonstrating modern Java features for scripting.

🎯 Purpose

NodeSnitch helps developers identify and manage disk space usage by node_modules directories across their system. It's also a showcase for modern Java features that make the language more accessible for scripting and quick tools.

✨ Featured Java Improvements

📜 Unnamed Classes (JEP 445)

This tool demonstrates the use of JEP 445: Unnamed Classes and Instance Main Methods, which allows for simpler, script-like Java code without the traditional class boilerplate. This makes Java more approachable for beginners and better suited for small utilities.

🚀 Shebang Files (JEP 330)

JEP 330: Launch Single-File Source-Code Programs introduced support for running Java source files directly using a shebang (#!) line. This allows Java files to be executed like shell scripts, making it more convenient for command-line tools.

🛠️ Requirements

  • Java 23 or later
  • Unix-like operating system (Linux, macOS)
  • Read access to your home directory

🏃 Usage

Simply run the script from your terminal:

  1. Clone the project
  2. Make it executable: 
    cd nodesnitch
chmod +x ./nodesnitch
./nodesnitch

The tool will:

  1. Search your home directory for node_modules folders
  2. Calculate the size of each directory
  3. Display results sorted by size (largest first)

📊 Output Example

Scanning for node_modules directories...

Found node_modules:
/Users/dev/project1/node_modules (1.2 GB)
/Users/dev/project2/node_modules (856 MB)
/Users/dev/test/node_modules (234 MB)

Total space used: 2.29 GB
