# Plan 29-01 Summary: Schema + Dominant Color Extraction
|
|
|
|
## What was built
|
|
- Installed Sharp image processing library for server-side color extraction
|
|
- Added `dominant_color`, `crop_zoom`, `crop_x`, `crop_y` columns to items, global_items, and thread_candidates tables
|
|
- Created `extractDominantColor()` function that resizes image to 1x1 pixel for weighted average color
|
|
- Integrated color extraction into both image upload endpoints (direct and from-url)
|
|
- Updated Zod schemas for items, candidates, and global items to accept new fields
|
|
- Generated Drizzle migration (db:push deferred — requires running database)
|
|

## Commits

|
|
|
| Task | Commit | Description |
|
|
|------|--------|-------------|
|
|
| 1 | cee1500 | Install Sharp for image processing |
|
|
| 2 | 36363a8 | Add dominantColor and crop fields to schema |
|
|
| 3 | b637b10 | Generate migration for image presentation fields |
|
|
| 4 | e305fa7 | Add dominant color extraction via Sharp |
|
|
| 5 | 2696b78 | Extract dominant color in image upload endpoints |
|
|
| 6 | 3480473 | Add image presentation fields to Zod schemas |
|
|
| 7 | — | No changes needed (storage service already spreads fields) |
|
|
|
|
## Deviations
|
|
- Task 3 (db:push): Database not accessible in dev environment — migration generated but push deferred to deployment. This is non-blocking for frontend work.
|
|
|
|
## Self-Check: PASSED
|
|
- Sharp installed: YES
|
|
- dominant_color in 3 tables: YES (grep confirms 3 occurrences)
|
|
- Zod schemas updated: YES (3 schemas)
|
|
- Upload returns dominantColor: YES
|
|
- Lint passes: YES
