Command-Line Developer Utility (File Inspector / Code Stats)
Build a terminal utility that analyzes a directory, counts code lines, calculates comment ratios, detects large files, and outputs formatted summary tables.
Prerequisites:Basic Python, Node.js, or Go syntaxFile system paths and loops
Recommended Tech Stack
Python or Node.jsBuilt-in file system libraries (os, path, fs)
Key Skills You Demonstrate
- ✓Recursive directory traversal and file path normalization
- ✓Command-line argument parsing (flags, options, help text)
- ✓Error handling for missing directories and permission errors
- ✓Publishing code to GitHub with a clean, professional README
Core Features to Implement
1.Filter files by extension (e.g. `--ext=.js,.py`)
2.Exclude directories like `.git` and `node_modules`
3.Colored terminal output with execution time benchmarks
4.Export results to JSON or CSV format
💡 Architecture Tip
Structure your code into small, single-responsibility functions: `parseArgs()`, `scanDirectory()`, `computeStats()`, `formatOutput()`.
Seniority Extension Ideas (To Stand Out in Interviews)
- →Package as an installable CLI tool using pip or npm
