Exploring Directories in Node.js

Basic Setup and Installation

First, create a new Node.js project and ensure it supports ES modules by adding this to your package.json:

Create two files:

1. fileExplorer.js - Contains the core functionality
2. main.js - Contains usage examples

Core Implementation (fileExplorer.js)

Usage Examples (main.js)

Common Use Cases

1. List All JavaScript Files

2. Get Size of All Images

3. Find Large Files

4. Check for Empty Directories

Error Handling Examples

Best Practices

1. Always use try-catch blocks for error handling
2. Use the utility functions for consistent patterns
3. Consider memory usage with recursive operations
4. Check directory accessibility before operations
5. Use async/await for cleaner code
6. Format file sizes for better readability

Remember to handle errors appropriately and consider performance implications when dealing with large directories or deep recursive operations.
