Static Analysis Tool
Summary
Freerange is a static analysis tool for TypeScript that tracks the numeric range of variables to prevent runtime errors like division by zero, NaN, and out-of-bounds array indexing. It operates at compile time using the official TypeScript API without requiring new syntax, annotations, or language forks.
Highlights
- Detects numeric errors such as NaN, Infinity, and division by zero during the build process
- Uses the official TypeScript API to ensure compatibility without requiring a new language
- Designed for high performance with negligible impact on TypeScript analysis time
- Includes an audit mode to provide refactor suggestions that make code more analysis-friendly
- Optimized for use by AI agents to guarantee UI layouts and refactor code automatically
