# FitPub - Phase 1 (MVP) Complete! 🎉
|
|
|
|
**Date Completed:** November 29, 2025
|
|
**Status:** ✅ All MVP features implemented and functional
|
|
|

|
|
|
|
## Overview
|
|
|
|
FitPub is a **federated fitness tracking platform** that integrates with the Fediverse through ActivityPub. Users can upload FIT files from GPS-enabled fitness devices, visualize their activities on interactive maps, and share workouts with followers across Mastodon, Pleroma, and other federated platforms.
|
|

|
|
|
|
✅ **Complete user journey:**

|
1. Register account
|
|
2. Login with JWT
|
|
3. Upload FIT file
|
|
4. View activity on map
|
|
5. Edit activity details
|
|
6. Set visibility (public/followers/private)
|
|
7. View activities on timeline
|
|
8. Click on user to see their profile
|
|
9. View user's public activities
|
|
10. Edit own profile
|
|
11. Follow/be followed (federation ready)
|
|
|
|
✅ **Federation tested:**
|
|
- ActivityPub actor profiles
|
|
- WebFinger discovery
|
|
- Follow requests (inbound)
|
|
- Accept activities
|
|
- Undo/unfollow
|
|
- Remote actor caching
|
|
|
|
✅ **All CRUD operations working:**
|
|
- Users (Create, Read, Update)
|
|
- Activities (Create, Read, Update, Delete)
|
|

## Known Limitations (By Design for MVP)
|
|
|
|
1. **Follower/following counts** - UI displays 0 (real counts in Phase 2)
|
|
2. **Follow button** - Placeholder on public profiles (Phase 2)
|
|
3. **Likes & comments** - Not implemented (Phase 2)
|
|
4. **Notifications** - Not implemented (Phase 2)
|
|
5. **Avatar upload** - URL-based only (file upload in Phase 5)
|
|
6. **Outbound federation** - Structure ready, not sending Create activities yet (Phase 2)
|
|
7. **Settings page** - Placeholder with links (Phase 2)
|
|
8. **Email/password change** - Not implemented (Phase 2)
|
|
9. **Advanced charts** - HR/pace over time (Phase 2)
|
|
10. **Error pages** - Using defaults (custom 404/403 in Phase 2)
|

## How to Use
|
|
|
|
**Prerequisites:**
|
|
- Java 17+
|
|
- Maven 3.8+
|
|
- PostgreSQL 13+ with PostGIS
|
|
- FIT files from GPS device
|
|
|
|
**Quick Start:**
|
|
1. Configure database in `application-dev.yml`
|
|
2. Run: `mvn spring-boot:run`
|
|
3. Navigate to: `http://localhost:8080`
|
|
4. Register account
|
|
5. Upload FIT file
|
|
6. Explore!
|
|
|
|
**Test with Federation:**
|
|
1. Add user in WebFinger format: `user@localhost:8080`
|
|
2. From Mastodon, search for local user
|
|
3. Follow the user
|
|
4. Check followers count (coming in Phase 2)
|
|
|

|
|
|
|
## Next Steps (Phase 2)
|
|
|
|
The MVP is **complete and functional**. Moving forward:
|
|
|
|
**Phase 2 priorities:**
|
|
- Implement likes and comments
|
|
- Populate follower/following counts with real data
|
|
- Add follow/unfollow buttons on profiles
|
|
- Send Create activities to followers when posting
|
|
- Build notifications system
|
|
- Enhanced charts (HR/pace over time)
|
|
- Custom error pages
|
|
- More complete settings page
