Technical Summary: Git Spark Git Spark is a comprehensive Git repository analytics and reporting tool that analyzes commit history to generate interactive HTML dashboards with visualizations of contributor activity, code change patterns, and repository health metrics. The project provides both a command-line interface and Node.js API, enabling users to extract insights from Git data in multiple formats (HTML, JSON, CSV, Markdown) with features including daily trend analysis, contributor statistics, file change tracking, and governance metrics based on conventional commit adherence and code churn patterns. Built with a modern polyglot tech stack combining PowerShell (45.3%), TypeScript (43.7%), and Shell scripting (10.0%), the tool leverages key dependencies like Commander.js for CLI orchestration, Chalk for terminal styling, Ora for progress indicators, and Boxen for formatted output presentation. The architecture emphasizes security-first design with strict Content Security Policy (CSP) implementation, SHA-256 hashing for inline assets, native SVG charting (avoiding external libraries), and self-contained report generation suitable for air-gapped environments—ensuring analytical integrity while maintaining full transparency about Git data limitations. The project targets Solutions Architects, DevOps engineers, and development teams seeking governance visibility and risk assessment through Git metadata, with distinctive features including email redaction options, timezone-aware daily trend analysis, progressive table pagination for performance, dark mode with persistent preferences, and comprehensive metric documentation explaining what Git analysis can and cannot reveal. Despite having zero stars, forks, or recent commits (classified as "stale" activity), the codebase demonstrates high technical currency (98/100) and production-readiness with Node.js ≥20.19.0 support, active npm package distribution, and a live demonstration site at markhazleton.github.io/git-spark/.
