Go-GarminConnect Porting Project - Progress and Roadmap

Current Progress

Authentication System:

• OAuth1/OAuth2 token flow implemented
• Token auto-refresh mechanism
• MFA handling with console prompts
• Session persistence to JSON file
• Comprehensive authentication tests

CLI Implementation:

• Command structure with Cobra
• Basic login command skeleton
• Session save/restore integration
• Status command implementation
• Logout functionality

API Implementation:

• Sleep data retrieval
• Stress tracking API
• Body composition models

1. CLI Completion (2 days)

• Complete login command with session handling
• Implement status command to verify authentication
• Add logout functionality with session cleanup

2. API Enhancement (3 days)

• Implement retry logic with exponential backoff
• Add structured request/response logging
• Develop sleep/stress endpoints
• Create body composition models

3. FIT File Support (2 days)

• Complete weight composition encoding
• Implement all-day stress FIT encoding
• Add HRV data to FIT export
• Validate FIT compatibility

Testing & Quality Assurance

• CLI end-to-end tests
• API integration tests
• FIT validation tests
• Performance benchmarks

Documentation & Examples

• CLI usage guide
• API reference documentation
• FIT file specification

Quality Gates

Before Release:

• 100% test coverage for core features
• Security audit of authentication flow
• Performance benchmarks met

Success Metrics

• Authentication success rate > 99%
• API response time < 1s
• FIT file compatibility 100%
