Details
Stack
- Node.js
- TypeScript
- npm
- GitHub Actions
- Semantic Versioning
Data Flow
- Input Coordinates → Validation
- Validated Data → Distance Engine
- Distance Results → Consumer APIs
- Package Releases → npm/GitHub
Decisions
- Kept API contracts small and deterministic for broad downstream use.
- Automated publish and verification checks to keep releases reliable.
