Clean up, format, lint and document entire codebase
Major cleanup and documentation effort:
Code Cleanup:
- Remove 668+ lines of dead code from legacy SBS-1 implementation
- Delete unused packages: internal/config, internal/parser, internal/client/dump1090
- Remove broken test file internal/server/server_test.go
- Remove unused struct fields and imports
Code Quality:
- Format all Go code with gofmt
- Fix all go vet issues
- Fix staticcheck linting issues (error capitalization, unused fields)
- Clean up module dependencies with go mod tidy
Documentation:
- Add comprehensive godoc documentation to all packages
- Document CPR position decoding algorithm with mathematical details
- Document multi-source data fusion strategies
- Add function/method documentation with parameters and return values
- Document error handling and recovery strategies
- Add performance considerations and architectural decisions
README Updates:
- Update project structure to reflect assets/ organization
- Add new features: smart origin, Reset Map button, map controls
- Document origin configuration in config examples
- Add /api/origin endpoint to API documentation
- Update REST endpoints with /api/aircraft/{icao}
Analysis:
- Analyzed adsb-tools and go-adsb for potential improvements
- Confirmed current Beast implementation is production-ready
- Identified optional enhancements for future consideration
The codebase is now clean, well-documented, and follows Go best practices
with zero linting issues and comprehensive documentation throughout.
