Create panel-dock-system.ts and navigator-panel.ts in features/
directory with proper init() implementations. Copy offline-manager
and reading-speed-tracker to features/ as well.
Fix bug where context parameter was unused in init() but referenced
throughout the file. Now properly stored as module-level variable
so all gesture handler functions can access it.
Convert view-modes.ts to init(context) pattern with:
- Paginated mode with pagination controls
- Scrolled mode for continuous reading
- Single and double column layouts
- Event-based navigation and mode switching
Complete the Feature Registration Pattern refactoring across all reader
modules. Each feature now exports an init(context) function and uses the
event-based architecture for loose coupling.

- Proper key bindings for RTL navigation
- Progress tracking adapted for RTL
8.2 Vertical Scroll Mode (Webtoon Style)

Plan now has complete coverage for all 4 media types: ebook, comic, manga, pdf
Removed 3 duplicate/incomplete sections:
- Section 5.8 (incomplete typography-engine.ts without font support)
- Section 5.12 (duplicate search.ts - kept version in section 5.9)
- Section 5.10.4 (incomplete reader.templ template - kept complete version in section 12.1)
The plan now contains only complete, implementation-ready sections:
- Complete typography-engine.ts with getFontStack() and all 8 bundled fonts
- Complete search.ts matching actual implementation with export functions
- Complete reader.templ SSR template with Alpine.js integration
This resolves confusion about which version to follow and ensures the plan
matches the actual codebase implementation.
Add 8 libre font families optimized for extended reading:
Variable fonts (continuous weight range):
- Literata: Modern book typeface for Google Books
- Crimson Pro: Screen-optimized serif
- Source Serif 4: Adobe's professional serif with optical size axis
- EB Garamond: Classic elegance with smooth italics
Static fonts (multiple weights):
- Libertinus Serif: Academic/technical with excellent math support
- Noto Serif: Maximum language coverage
- Charis SIL: Multilingual specialist with extensive Latin support
- IBM Plex Serif: IBM's corporate serif family
All fonts provided in WOFF2 format for optimal compression. Variable fonts
offer continuous weight ranges (200-900) while static fonts provide specific
weights for predictable rendering. Total footprint: ~7.5MB.
These fonts provide excellent readability for extended reading sessions
across all supported languages and scripts.
- epub-parser.ts: EPUB2/EPUB3 parsing with container, encryption, and navigation support
- fb2-parser.ts: FictionBook 2.0/XML parser with metadata and TOC extraction
- txt-parser.ts: Plain text parser with encoding detection and chapter detection
- html-parser.ts: HTML document parser with metadata and structure extraction
All parsers convert their respective formats to the Common Intermediate Format (CIF)
for universal handling. Client-side parsing provides instant access without server
processing for common ebook formats.
Phase 1 focuses on these client-side parsers. Server-side parsers for MOBI, AZW3,
DOCX, and RTF will be implemented in Phase 2.5.
- html-renderer.ts: HTML content rendering with security sanitization and font loading
- typography-engine.ts: Advanced typography with ligatures, hyphenation, and optimization
- cfi-navigator.ts: EPUB CFI navigation for precise location tracking and jumping
- search.ts: Full-text search with highlighting across ebook content
The ebook reader provides a premium reading experience with:
- Clean HTML rendering with XSS protection
- Publisher-quality typography with custom fonts
- Precise CFI-based navigation for EPUBs
- Fast full-text search with result highlighting
This handles EPUB, FB2, TXT, and HTML ebook formats client-side.
- reader-shell.ts: Main initialization, Alpine.js integration, media type detection
- progress-indicator.ts: Reading progress tracking and display components
- settings-manager.ts: User settings persistence and retrieval
- panel-dock-system.ts: Dockable panel management with drag/drop and collapse
- parser-manager.ts: Parser selection and format detection system
These core modules provide the foundation for all reader types with
shared functionality for progress tracking, settings management, and
the flexible panel docking system.
Define comprehensive TypeScript interfaces for reader functionality:
- Common Intermediate Format (CIF) for universal ebook representation
- Parser capabilities and format detection types
- Reader metadata and chapter structure interfaces
- Panel layout and dock system types
- Reading progress and settings interfaces
- Dictionary and search functionality types
These types provide the foundation for type-safe reader implementation
across all media types (ebook, comic, manga, pdf).
- Update Section 1.4 with detailed data flow diagram showing SSR skeleton approach
- Add Section 1.5 documenting SSR vs Client-Side responsibilities
- Clarify that SSR provides HTML shell with initial data, TypeScript handles UI
- Document specific examples of what SSR renders vs what TypeScript manages
- Remove confusing 'embedded JSON' terminology for clearer hybrid approach
These changes make the implementation plan more precise and implementation-ready
by clearly separating SSR (Go template) from client-side (TypeScript) concerns.
- Fix function signatures in reader.go (c echo.Context -> c *echo.Context)
- Replace non-existent UserHasLibraryAccess with GetUserVisibleLibraries pattern
- Implement SSR reader route in router/reader.go with proper access control
- Add inline library access checking following existing codebase patterns
- Fix ReadingProgress struct to use LastReadAt instead of CreatedAt/UpdatedAt
- Ensure all reader endpoints use consistent library access validation
This provides the backend foundation for the reader feature with proper
access control and SSR rendering capabilities.
- Add panel_layout to getDefaultSettings() for dockable panels
- Remove template rendering from ShowReader (router handles SSR)
- Fix pgtype.Int4 marshaling to JSON (no explicit int conversion)

- Support all media types: ebook, comic, manga, pdf
- Initialize reader shell via Alpine.js data attribute
- Add modular dockable panel architecture with:
- Panel dock system (drag, lock, snap-back, window-shade)
- TOC, Settings, Navigator, Bookmarks as dockable components
- Lock toggle to prevent accidental moves
- Snap-back to last valid position if dropped in invalid area
- Per-user layout stored in reader_settings JSONB
- Update TypeScript types with PanelLayoutSettings and PanelState
- Add panel-dock-system.ts implementation to plan
- Add navigator-panel.ts for Affinity-style page navigation
- Update reader template with dockable panels and lock buttons
- Add Section 2.4 with database/Go implementation issues and fixes
- Document schema changes (DECIMAL -> REAL)
- Document all type fixes needed in reader.go
- Changed words_per_minute, pages_per_minute, total_reading_minutes from DECIMAL(6,2) / DECIMAL(8,2) to REAL
- REAL (pgtype.Float4) is sufficient for reading statistics and simplifies Go code
- No precision loss for typical reading speed values (200-400 wpm, 0.5-3.0 pages/min)
