- "Cascade delete on entry deletion"

patterns-established:

- "Image storage: data/uploads/originals/{id}.{ext}, data/uploads/thumbnails/{id}.jpg"

# Phase 03 Plan 01: Image Infrastructure Summary
|
||||
|
||||
**Sharp-based image storage with thumbnails, EXIF auto-rotation, and API endpoints for serving images**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 4 min
|
||||
- **Started:** 2026-01-29T14:21:57Z
|
||||
- **Completed:** 2026-01-29T14:26:00Z
|
||||
- **Tasks:** 3
|
||||
- **Files modified:** 6
|
||||
|
||||
## Accomplishments
|
||||
- Images table with entryId foreign key and cascade delete
|
||||
- ImageRepository with full CRUD (create, getById, getByEntryId, delete, deleteByEntryId)
|
||||
- File storage utilities with directory management
|
||||
- Thumbnail generation with EXIF auto-rotation for mobile photos
|
||||
- GET endpoints for original images and thumbnails with proper caching
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 1: Database schema and repository for images** - `f5b5034` (feat)
|
||||
2. **Task 2: File storage and thumbnail generation utilities** - `0987d16` (feat)
|
||||
3. **Task 3: API endpoints for serving images** - `b3640e7` (feat)
|
||||
|
||||
## Files Created/Modified
|
||||
- `src/lib/server/db/schema.ts` - Added images table with entryId FK
|
||||
- `src/lib/server/db/repository.ts` - Added imageRepository singleton
|
||||
- `src/lib/server/images/storage.ts` - File I/O utilities for originals/thumbnails
|
||||
- `src/lib/server/images/thumbnails.ts` - Sharp thumbnail generation with EXIF rotation
|
||||
- `src/routes/api/images/[id]/+server.ts` - GET endpoint for original images
|
||||
- `src/routes/api/images/[id]/thumbnail/+server.ts` - GET endpoint for thumbnails
|
||||
|
||||
## Decisions Made
|
||||
- **Thumbnails always JPEG:** Regardless of original format, thumbnails saved as .jpg for consistency and size optimization
|
||||
- **EXIF rotation first:** Call sharp.rotate() before resize to handle mobile photo orientation
|
||||
- **Immutable caching:** Cache-Control: public, max-age=31536000, immutable since image content never changes by ID
|
||||
- **Cascade delete:** ON DELETE CASCADE on entryId so deleting entry removes images from DB (files handled separately)
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None - plan executed exactly as written.
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
None.
|
||||
|
||||
## User Setup Required
|
||||
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- Image infrastructure ready for upload API (03-02)
|
||||
- Repository and storage utilities available for upload processing
|
||||
- API endpoints ready to serve uploaded images
