Books Module - Desktop Implementation
Overview
The Books module has been fully implemented for desktop using Koin for dependency injection and a desktop-optimized UI.
Implementation Details
Architecture
Desktop-specific components:
BooksRepositoryDesktop- In-memory implementation (can be replaced with SQLite/file storage)BooksViewModel- Desktop ViewModel using KoinBooksScreen- Desktop-optimized UI with grid layoutBooksScreenDestination- Navigation destination composable
Key Files
Data Layer:
composeApp/src/desktopMain/.../data/BooksRepositoryDesktop.kt- Desktop repository implementation
ViewModels:
composeApp/src/desktopMain/.../viewmodels/BooksViewModel.kt- Desktop ViewModel
UI:
composeApp/src/desktopMain/.../screens/BooksScreen.kt- Main books screencomposeApp/src/desktopMain/.../composables/AddBookDialog.kt- Add book dialogcomposeApp/src/desktopMain/.../composables/BookDetailDialog.kt- Book detail dialog with stats
Navigation:

DI:
Modules.kt- Koin module providing Books dependencies
Features
✅ Desktop-optimized UI:
- Grid layout with adaptive columns
- Large clickable cards
- Search bar with instant filtering
- Status filter chips
- Modal dialogs for add/edit operations
✅ Full functionality:
- Add books (title + optional author)
- Filter by status (All, Want, Reading, Finished, Dropped)
- Search by title/author
- View book details with stats
- Log reading minutes
- Change book status
- View reading statistics
Storage
Current Implementation:
- Uses in-memory storage (
ConcurrentHashMap) - Data is lost on app restart
Future Improvements:
- Replace with SQLite for persistence
- Or use SQLDelight for multiplatform database support
- Or implement file-based JSON storage
Navigation
Access the Books screen:
navController.navigate(Screen.Books.route)Route: "books"
Usage
-
Add a Book:
- Click “Add Book” button
- Enter title (required)
- Optionally enter author
- Click “Add”
-
View Book Details:
- Click on any book card
- View stats and actions in modal dialog
-
Log Reading Time:
- Open book detail
- Click “Log Minutes”
- Enter minutes and date
- Click “Log”
-
Change Status:
- From book detail dialog:
- “Start Reading” → READING
- “Finish Book” → FINISHED
- “Drop Book” → DROPPED
- From book detail dialog:
-
Filter & Search:
- Use status chips to filter
- Use search bar for instant filtering
Dependencies
- Koin - Dependency injection
- Compose Desktop - UI framework
- Books Domain - Use cases and models
Notes
- Storage: Currently in-memory only. For production, implement persistent storage.
- Data Sharing: Desktop and mobile use separate storage (no sync in current implementation).
- UI Patterns: Follows desktop design patterns with modals, grids, and larger touch targets.
Future Enhancements
-
Persistent Storage:
- Implement SQLite or SQLDelight
- Or file-based JSON storage
-
Data Sync:
- Add server-side API
- Sync between desktop and mobile
-
Enhanced Stats:
- Charts and graphs
- Reading trends
- Goal tracking
