# Story 3.3: Summary History Management ## Status Ready for Implementation ## Story **As an** authenticated user **I want** to view and manage my summary history **So that** I can reference previous summaries, search through them, and organize my video insights ## Acceptance Criteria 1. **History Display**: Summary history displays in reverse chronological order with pagination 2. **Search Functionality**: Filter summaries by video title, content, date range, or AI model used 3. **Favorites System**: Users can star/favorite summaries for quick access 4. **Bulk Operations**: Support bulk delete and export with confirmation dialogs 5. **Summary Sharing**: Generate shareable links (public or private) for individual summaries 6. **Export Options**: Export entire history or filtered results as JSON, CSV, or ZIP archive 7. **Summary Management**: Edit summary titles, add notes, and organize with tags 8. **Usage Statistics**: Display summary count, total videos processed, and cost tracking ## Technical Requirements ### Backend Implementation #### Database Schema Updates ```python # Add to Summary model (backend/models/summary.py) is_starred = Column(Boolean, default=False, index=True) notes = Column(Text) # User's personal notes tags = Column(JSON) # Array of user tags shared_token = Column(String(64), unique=True, nullable=True) # For sharing is_public = Column(Boolean, default=False) view_count = Column(Integer, default=0) # Add indexes for performance Index('idx_user_starred', 'user_id', 'is_starred') Index('idx_user_created', 'user_id', 'created_at') ``` #### API Endpoints (backend/api/summaries.py) ```python router = APIRouter(prefix="/api/summaries", tags=["summaries"]) # GET /api/summaries - List user's summaries with filters # GET /api/summaries/{id} - Get single summary # PUT /api/summaries/{id} - Update summary (star, notes, tags) # DELETE /api/summaries/{id} - Delete single summary # POST /api/summaries/bulk-delete - Delete multiple summaries # GET /api/summaries/search - Advanced search # GET /api/summaries/starred - Get starred summaries # POST /api/summaries/{id}/share - Generate share link # GET /api/summaries/shared/{token} - Access shared summary # GET /api/summaries/export - Export summaries # GET /api/summaries/stats - User statistics ``` ### Frontend Implementation #### Components Structure ``` frontend/src/ ├── pages/ │ └── history/ │ ├── SummaryHistoryPage.tsx # Main history page │ └── SharedSummaryPage.tsx # Public share view ├── components/ │ └── summaries/ │ ├── SummaryList.tsx # List with pagination │ ├── SummaryCard.tsx # Individual summary card │ ├── SummarySearch.tsx # Search and filters │ ├── SummaryDetails.tsx # Full summary view │ ├── SummaryActions.tsx # Star, share, delete actions │ ├── BulkActions.tsx # Bulk operations toolbar │ ├── ExportDialog.tsx # Export configuration │ └── UsageStats.tsx # Statistics display └── hooks/ ├── useSummaryHistory.ts # History data fetching ├── useSummarySearch.ts # Search functionality └── useSummaryActions.ts # CRUD operations ``` ## Tasks / Subtasks ### Task 1: Database Schema Updates (4 hours) -

[ ] Create frontend component tests - [ ] Update API documentation - [ ] Add user documentation ## Dependencies ### Technical Dependencies - Story 3.1: User Authentication (✅ Complete) - Story 3.2: Frontend Auth Integration (✅ Complete) - Database models with user relationships - Authentication middleware - Export service from Epic 2 ### External Dependencies - React Query for data fetching - Tanstack Table for data grid - date-fns for date handling - Chart.js for statistics visualization ## Definition of Done - [ ] All database migrations applied successfully - [ ] API endpoints return correct data with proper pagination - [ ] Search functionality works across title, content, and tags - [ ] Starring system persists and filters correctly - [ ] Bulk operations handle edge cases gracefully - [ ] Share links work for both authenticated and public access - [ ] Export generates valid files in all formats - [ ] Frontend displays history with smooth scrolling - [ ] All actions show appropriate loading states - [ ] Mobile responsive design works correctly - [ ] Unit tests pass with >80% coverage - [ ] Integration tests verify complete flows - [ ] Performance: Page loads in <2 seconds with 100+ summaries - [ ] Accessibility: WCAG 2.1 AA compliance - [ ] Documentation updated ## Notes ### Implementation Considerations 1. **Performance**: Use cursor-based pagination for large datasets 2. **Caching**: Implement Redis caching for frequently accessed summaries 3. **Search**: Consider full-text search with PostgreSQL or Elasticsearch 4. **Export**: Stream large exports to prevent memory issues 5. **Sharing**: Use signed URLs with expiration for security 6. **Mobile**: Implement swipe gestures for mobile actions ### Future Enhancements - Collaborative folders for team sharing - Summary collections/playlists - Advanced analytics dashboard - Integration with note-taking apps - Automated summary recommendations - Version history for edited summaries ### Design Mockup Structure ``` ┌─────────────────────────────────────────────┐ │ 🎬 Summary History [Stats] │ ├─────────────────────────────────────────────┤ │ [Search...] [Date] [Tags] [Model] [Export] │ ├─────────────────────────────────────────────┤ │ [✓] Select All [★ Star] [🗑 Delete] [↗ Share]│ ├─────────────────────────────────────────────┤ │ ┌──────────────┐ ┌──────────────┐ │ │ │ Video Title │ │ Video Title │ │ │ │ ★ 2 days ago │ │ 5 days ago │ │ │ │ Summary... │ │ Summary... │ │ │ │ [View] [···] │ │ [View] [···] │ │ │ └──────────────┘ └──────────────┘ │ │ │ │ [Load More] │ └─────────────────────────────────────────────┘ ``` ## Estimated Time: 36 hours **Priority**: High -
