🧠 Context / Focus for Today

Implement Garmin workout export/sync with Training API and activity matching. Add automatic Garmin sync with auto-export, cron jobs, and webhook support. Fix day-of-week calculation for workout creation. Improve auto-sync reliability.

✔️ Things I Got Done Today

Garmin Workout Export/Sync

Training API Integration

  • Implement Garmin workout export/sync with Training API and activity matching:
    • Full workout export capability
    • Activity matching for imports
    • Training API integration
    • Professional sync functionality

Automatic Garmin Sync

Auto-Export & Sync

  • Add automatic Garmin sync: auto-export on workout create/update, cron job for imports, and webhook support:

    • Automatic export on workout creation
    • Automatic export on workout updates
    • Cron job for periodic imports
    • Webhook support for real-time sync
    • Seamless synchronization

  • Improve auto-sync reliability: add Garmin connection check, delay for DB write, and better error logging:

    • Connection validation before sync
    • Delay for database write completion
    • Better error logging
    • Improved reliability

  • Fix auto-sync: call export API directly instead of sync route for better reliability:

    • Direct API calls
    • Better reliability
    • Improved performance

  • Add automatic deletion sync: remove workouts from Garmin when deleted from calendar:

    • Automatic deletion sync
    • Bidirectional sync
    • Better data consistency

Workout Creation Fixes

Day-of-Week Calculation

  • Fix day-of-week calculation for workout creation:
    • Add explicit day-of-week instructions to AI system prompt
    • Add post-processing to verify and correct dates when user requests specific days
    • Fixes issue where 'Saturday' requests created workouts for Sunday
    • Better date accuracy
    • Improved reliability

Dependencies

Drag and Drop

  • Update package.json and package-lock.json with @dnd-kit dependencies:

    • Drag and drop library
    • Better workout management
    • Improved UX

  • Add missing DragAndDropWorkoutBuilder component:

    • Complete component implementation
    • Better functionality

Code Fixes

Error Handling & Migration

  • Add better error handling for missing migration and migration instructions:

    • Better error messages
    • User guidance
    • Improved reliability

  • Make export work without migration - gracefully handle missing Garmin columns:

    • Backward compatibility
    • Graceful degradation
    • Better error handling

  • Fix: use refreshWorkouts instead of loadWorkouts:

    • Proper function usage
    • Better data refresh

  • Fix TypeScript error: remove duplicate insertError check:

    • Code cleanup
    • Better code quality

🚧 In Progress

  • Garmin sync (auto-sync complete, additional refinements planned)
  • Workout creation (day-of-week fixes complete, additional improvements planned)

🎯 Targets for Tomorrow

  1. Continue Garmin sync improvements — additional reliability enhancements
  2. Enhance workout creation — additional date handling improvements
  3. Test auto-sync — verify reliability in production
