# Phase 1 Plan 02: Backend API Summary
**Item/category CRUD with Zod-validated Hono routes, computed totals via SQL aggregates, image upload, and 30 passing tests via TDD**
## Performance
- **Duration:** 3 min
- **Started:** 2026-03-14T21:37:37Z
- **Completed:** 2026-03-14T21:40:54Z
- **Tasks:** 2
- **Files modified:** 13
## Accomplishments
- Complete item CRUD service layer with category join queries
- Category CRUD with Uncategorized reassignment on delete (transaction-safe)
- Per-category and global weight/cost/count totals via SQL SUM/COUNT aggregates
- Hono API routes with Zod request validation for all endpoints
- Image upload endpoint with file type and size validation
- 30 tests passing (20 unit + 10 integration) built via TDD
## Task Commits
Each task was committed atomically:
1. **Task 1: Service layer with tests (RED)** - `f906779` (test)
2. **Task 1: Service layer implementation (GREEN)** - `22757a8` (feat)
3. **Task 2: API routes, image upload, integration tests** - `029adf4` (feat)
## Files Created/Modified
- `src/server/services/item.service.ts` - Item CRUD business logic with category join
- `src/server/services/category.service.ts` - Category CRUD with reassignment on delete
- `src/server/services/totals.service.ts` - Per-category and global totals aggregation
- `src/server/routes/items.ts` - Hono routes for /api/items with Zod validation
- `src/server/routes/categories.ts` - Hono routes for /api/categories with delete protection
- `src/server/routes/totals.ts` - Hono route for /api/totals
- `src/server/routes/images.ts` - Image upload with type/size validation
- `src/server/index.ts` - Registered all API routes
- `tests/services/item.service.test.ts` - 7 unit tests for item CRUD
- `tests/services/category.service.test.ts` - 7 unit tests for category CRUD
- `tests/services/totals.test.ts` - 4 unit tests for totals aggregation
- `tests/routes/items.test.ts` - 6 integration tests for item API
- `tests/routes/categories.test.ts` - 4 integration tests for category API
## Decisions Made
- Service functions accept `db` as first parameter with production default for dependency injection and testability
- Routes use Hono context variables (`c.get("db")`) for DB injection, enabling integration tests with in-memory SQLite without mocking
- Totals computed via SQL aggregates on every read per RESEARCH.md recommendation (never cached)
- `updateItemSchema.omit({ id: true })` used for PUT routes since id comes from URL params
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None.
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- All backend API endpoints ready for frontend consumption (Plan 01-03)
- Service layer provides clean interface for TanStack Query hooks
- Test infrastructure supports both unit and integration testing patterns
## Self-Check: PASSED
All 12 created files verified present. All 3 task commits verified in git log.
