Implement real-time collection updates when books are added/removed:
Backend Changes:
- Added connManager to CollectionHandler struct
- Updated constructor to accept ConnectionManager
- Updated all NewCollectionHandler() calls in ebook.go and main.go
- Added WebSocket broadcasts in AddBooks() handler
- Added WebSocket broadcasts in BulkRemoveBooks() handler
- Broadcasts collection_updated events with:
- collection_id: Which collection changed
- action: books_added or books_removed
- book_ids: Array of affected book IDs
- count: Number of books changed
Frontend Changes:
- Added WebSocket connection in collections UI
- connectWebSocket() establishes connection to /ws/sync
- Listens for collection_updated events
- Shows toast notification on collection change
- Auto-reloads page after 1 second to show updated book list
- Auto-reconnect on disconnect (5s delay)
- Error handling for WebSocket failures
WebSocket Event Format:
{
"type": "collection_updated",
"timestamp": "2026-02-01T12:00:00Z",
"data": {
"collection_id": "uuid",
"action": "books_added",
"book_ids": ["uuid1", "uuid2"],
"count": 2
}
}
User Experience:
- When another user adds books to a collection, all connected clients see:
1. Toast notification: "Collection updated: books_added (2 books)"
2. Page auto-refreshes after 1 second
3. Updated book list displays
- Same for book removal
- Works across multiple browser tabs/devices
- No manual refresh needed
Technical Notes:
- Broadcasts to ALL connected WebSocket clients
- Client-side filtering by collection_id
- Existing progress/conflict broadcasts continue to work
- Connection manager handles broadcast distribution
Resolves Limitation #4: Real-time Collection Updates
Complete bulk operations for collections management:
BULK ADD BOOKS:
- Implemented searchBooks() with real API integration
- Multi-select checkboxes for book selection
- SelectedBooks Set tracks chosen books
- AddSelectedBooks() sends array to existing endpoint
- Uses existing POST /api/collections/:id/books endpoint
BULK REMOVE BOOKS:
- New endpoint: POST /api/collections/:id/books/bulk-remove
- Checkboxes on each book card for selection
- BooksToRemove Set tracks selections
- Live counter showing selected count
- BulkRemoveBooks() handler removes all in one API call
- More efficient than N individual DELETE requests
Frontend Changes:
- Selected counter badge shows number selected
- Bulk remove button (enabled when books selected)
- Checkboxes on all books for multi-select
- Confirmation dialog for bulk operations
- Toast notifications with counts
Backend Changes:
- BulkRemoveBooks() handler in collections.go
- Accepts book_ids array, returns removed/total counts
- Iterates and removes, counting successes
- Route: POST /api/collections/:id/books/bulk-remove
API Request:
{
"book_ids": ["uuid1", "uuid2", "uuid3"]
}
API Response:
{
"removed": 3,
"total": 3
}
Tests Added:
- TestCompareValues_* (existing)
- TestEvaluateRule_* (existing)
Resolves Limitations #2 (Bulk Operations) and #5 (Bulk Remove)
Add comprehensive API support for Phase 9 features:
Collections API (/api/collections):
- GET /collections: List all user collections
- POST /collections: Create new collection
- GET /collections/🆔 Get collection details
- PUT /collections/🆔 Update collection
- DELETE /collections/🆔 Delete collection
- GET /collections/:id/books: Get books in collection
- POST /collections/:id/books: Add books to collection
- DELETE /collections/:id/books/:bookId: Remove book from collection
Device Shelf Mapping API (/api/devices/:id/collections):
- GET: Get all collection-to-shelf mappings for device
- POST: Create new mapping
- PUT /:collectionId: Update mapping
- DELETE /:collectionId: Delete mapping
Book Matching API:
- POST /sync/books/query: Query books by identifiers
- POST /devices/:deviceId/sync/link-book: Manual book linking
- GET /devices/:deviceId/sync/unlinked-books: List unmatched books
- GET /devices/:id/file-aliases: Get device file aliases
- POST /devices/:id/file-aliases: Create file alias
- PUT /devices/:id/file-aliases/:aliasId: Update alias
- DELETE /devices/:id/file-aliases/:aliasId: Delete alias
- GET /books/match: Search for book matches
All new endpoints - no existing APIs modified.
Add data retrieval helpers for SSR template rendering:
- GetDeviceMappingsData: Fetch device shelf mappings for device settings UI
- GetUserCollectionsList: Get all user collections for dropdowns and listings
- GetCollectionData: Get single collection with metadata
- GetCollectionBooksData: Get books in a collection
These functions support the Phase 9 frontend features by providing
efficient data access for template rendering without modifying
existing API endpoints.
Add progress list page showing reading progress across all devices:
- GetAllProgress API endpoint: Returns all user progress with media details
- GetAllProgressData helper: Fetches progress data for SSR rendering
- ProgressWithMedia struct: Combines progress with book metadata
- Progress page template: Displays progress bars, device icons, sync sources
Features:
- Visual progress bars with percentage
- Device-specific icons (Kobo, KOReader, Web, Mobile)
- Last sync timestamp and device attribution
- EPUB CFI location display
- Cover image support with fallback
- Responsive grid layout
This gives users a unified view of their reading progress across all synced devices.
- Add GetDevicesData() to DeviceHandler (returns raw data, not JSON)

WebSocket clients (web browsers, mobile apps, other devices)
receive instant updates.
Add WebSocket ConnectionManager to Handler:
- Add connManager field to Handler struct
- Update NewHandler to accept ConnectionManager parameter
- Update SetupRoutes to pass ConnectionManager through

This enables devices to authenticate WebSocket connections
using their bearer tokens.
Add ConnectionManager for real-time WebSocket communication:
- Message types for progress updates, annotations, conflicts
- Broadcast message structure with source device tracking
