# Phase 14 Plan 03: Service Layer Async Conversion Summary
|
|
|
|
**All 9 service files (30 functions) converted from synchronous SQLite to async PostgreSQL operations with PGlite smoke test validation**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 4 min
|
|
- **Started:** 2026-04-04T10:31:16Z
|
|
- **Completed:** 2026-04-04T10:35:35Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 9
|
|
|
|
## Accomplishments
|
|
- Converted 30 exported service functions across 9 files to async/await
|
|
- Removed all SQLite-only method calls (.all(), .get(), .run()) from service layer
|
|
- Converted 5 transaction callbacks to async pattern (category delete, thread resolve/reorder, setup sync)
|
|
- Fixed OAuth boolean type mismatch (used: 0/1 -> false/true)
|
|
- Server startup now awaits async seedDefaults()
|
|
- PGlite smoke test validates createItem service works end-to-end against async DB
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Convert core data services to async** - `4d705af` (feat)
|
|
2. **Task 2: Convert auth/oauth/csv services, update server index** - `75bf3e0` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `src/server/services/item.service.ts` - 6 async functions for item CRUD
|
|
- `src/server/services/category.service.ts` - 4 async functions, async transaction in deleteCategory
|
|
- `src/server/services/thread.service.ts` - 10 async functions, async transactions in resolveThread/reorderCandidates
|
|
- `src/server/services/setup.service.ts` - 8 async functions, async transaction in syncSetupItems
|
|
- `src/server/services/totals.service.ts` - 2 async functions for aggregate queries
|
|
- `src/server/services/auth.service.ts` - 10 async functions for user/session/API key management
|
|
- `src/server/services/oauth.service.ts` - 7 async functions, boolean conversion for used field
|
|
- `src/server/services/csv.service.ts` - 2 async functions for CSV export/import
|
|
- `src/server/index.ts` - seedDefaults() call now awaited
|
|
|
|
## Decisions Made
|
|
- Removed .all() calls entirely since async Drizzle returns arrays directly from queries
|
|
- Used destructured array pattern `const [row] = await ...` for all single-row queries (replaces .get())
|
|
- Converted OAuth `used` field from integer (0/1) to native boolean (false/true) to match PostgreSQL schema
|
|
- image.service.ts was already fully async (no DB calls), no changes needed
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 3 - Blocking] Installed missing @electric-sql/pglite dependency**
|
|
- **Found during:** Task 2 (PGlite smoke test)
|
|
- **Issue:** pglite package not installed, required by test helper db.ts for in-memory PostgreSQL
|
|
- **Fix:** Ran `bun add @electric-sql/pglite`
|
|
- **Files modified:** package.json (auto-updated by bun)
|
|
- **Verification:** Smoke test passes, createItem returns valid item
|
|
- **Committed in:** Part of bun lockfile (auto-managed)
|
|
|
|
---
|
|
|
|
**Total deviations:** 1 auto-fixed (1 blocking)
|
|
**Impact on plan:** Dependency installation required for smoke test. No scope creep.
|
|
|
|
## Issues Encountered
|
|
None - mechanical conversion applied consistently across all files.
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Known Stubs
|
|
None - all service functions are fully wired with real async database operations.
|
|
|
|
## Next Phase Readiness
|
|
- All service functions are async, ready for route layer conversion (Plan 04)
|
|
- Callers (route handlers) still call these functions synchronously -- they need to await the returned promises
|
|
- Test infrastructure (PGlite) confirmed working for service-level validation
