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
