🏗️ Technical Implementation

Template Architecture

• SSR (Server-Side Rendering): All pages use Go templates for initial render
• HTMX Integration: Ready for interactive enhancements
• Responsive Design: Mobile-first with TailwindCSS
• Theme Support: Dynamic theme switching via CSS variables

Handler Functions

• GetAllProgressData(): Fetch progress for SSR rendering
• GetDeviceMappingsData(): Fetch device shelf mappings
• GetUserCollectionsList(): Fetch user collections
• GetCollectionData(): Fetch single collection
• GetCollectionBooksData(): Fetch books in collection

Route Organization

• API Routes: /api/collections, /api/devices/:id/collections, /api/progress
• SSR Routes: Server-rendered pages for better SEO and performance
• Protected Routes: All require JWT authentication

📝 Known Limitations & Future Enhancements

Current Limitations

1. Rule Testing Preview: Collection rules can be created/saved but there's no "test" or "preview" button to see which books would match before activating

   • Backend rules engine exists (internal/services/collection_service.go)
   • UI for creating rules exists (templates/collection_rules.templ)
   • Missing: Preview/test function to show matching books

2. Bulk Add UI Incomplete: Backend supports adding multiple books at once (POST /api/collections/:id/books with book_ids[] array), but frontend UI is incomplete

   • ✅ Backend: AddBooks() accepts array of book IDs
   • ❌ Frontend: searchBooks() is placeholder ("Book search coming soon!")
   • ❌ Frontend: selectedBooks Set referenced but not implemented
   • Missing: Multi-select interface for adding multiple books

3. Collection-Specific Search: Global search exists (/api/media-items/search) but not integrated into collections UI

   • ✅ Backend: Filtered search exists (/api/media-items/filtered with author_filter, genre_filter, etc.)
   • ✅ Backend: Fuzzy search with word_similarity
   • ❌ Frontend: Collections UI doesn't wire up to search endpoints
   • Missing: Search/filter bar within collection detail view

4. Real-time Collection Updates: WebSocket infrastructure exists but collections don't auto-update when books are added/removed from other views

   • ✅ Backend: WebSocket manager (internal/sync/websocket.go)
   • ✅ Backend: Broadcast for progress, conflicts, sync events
   • ❌ Frontend: Collections UI doesn't use WebSocket
   • ❌ Backend: No broadcast when books added/removed from collections
   • Missing: Collection change events + WebSocket listener in UI

5. Bulk Remove: Can only remove one book at a time from collections

   • ✅ Backend: Remove single book (DELETE /api/collections/:id/books/:bookId)
   • ❌ Backend: No bulk remove endpoint
   • ❌ Frontend: No multi-select for removal
   • Missing: Batch delete functionality

✅ Already Implemented (Previous Phases)

1. OPDS Integration: ✅ Complete (Phase 5) - internal/handlers/opds.go

   • OPDS catalog feeds per device

2. Advanced Book Matching: ✅ Complete (Phase 3) - internal/handlers/book_matching.go

   • Multi-identifier matching (UUID, SHA-256, ISBN, OPF)
   • Confidence scoring algorithm
   • Manual linking interface
   • Unlinked book detection

3. Conflict Resolution: ✅ Complete (Phase 6) - internal/handlers/conflicts.go

   • Automatic conflict detection
   • Manual merge UI (templates/conflicts.templ)
   • Winner selection (Kobo, KOReader, Web, Manual)
   • WebSocket notifications

4. Real-time Updates: ✅ Complete - internal/sync/websocket.go, internal/handlers/websocket.go

   • WebSocket connection manager
   • Progress update broadcasts
   • Annotation update broadcasts
   • Conflict detection notifications

   • Route: /ws/sync

5. Advanced Search: ✅ Complete - internal/handlers/ebook.go

   • Fuzzy search with word_similarity (threshold > 0.3)
   • ILIKE pattern matching for fast results
   • Fuzzy fallback when no exact matches
   • Route: GET /api/media-items/search?q=query

Future Enhancements (Phase 10+)
