|
provides: Expense JE patterns and FinancialReportService cash flow approach
|
|
provides:
|
|
- DashboardService with 6 metric aggregation methods
|
|
- GET /api/dashboard endpoint returning composite dashboard metrics
|
|
- Integration tests verifying all metric accuracy
|
|
affects: [05-02 (dashboard UI will consume this API), 05-05 (e2e tests)]

# Tech tracking

tech-stack:

added: []
|
|
patterns:
|
|
- "Dashboard metric aggregation via Prisma aggregate/groupBy"
|
|
- "Parallel Promise.all for independent metric queries"

- src/lib/__tests__/dashboard-service.test.ts
|
|
|
|
key-decisions:
|
|
- "Revenue metrics use Payment.createdAt (not paymentDate) for today/month filtering -- createdAt is when the record was created in the system"
|
|
- "Cash flow uses same approach as FinancialReportService.getIncomeStatement -- POSTED JE lines on revenue (4xxx) and expense (5xxx) accounts with normal balance logic"
|
|
- "Collector summary uses Collection.createdAt for today filter and Remittance PENDING status for unverified count (SUBMITTED maps to PENDING enum)"
|
|
- "getDashboardSummary runs all 5 metric methods in parallel via Promise.all for efficiency"
|
|
|
|
patterns-established:
|
|
- "Dashboard aggregation pattern: static class methods accepting TenantPrismaClient + tenantId, returning typed metric interfaces"

# Phase 5 Plan 1: Dashboard Metrics API Summary
|
|
|
|
**DashboardService aggregating revenue, overdue, subscriber status, cash flow, and collector metrics via Prisma aggregate/groupBy with GET /api/dashboard endpoint**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 3 min
|
|
- **Started:** 2026-03-05T09:20:10Z
|
|
- **Completed:** 2026-03-05T09:23:23Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 3
|
|
|
|
## Accomplishments
|
|
- DashboardService with 6 methods covering DASH-01 through DASH-04 plus collector summary
|
|
- GET /api/dashboard returns all metrics in a single response, with optional date range for cash flow
|
|
- 6 integration tests all passing first run, verifying metric accuracy against seeded data
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: DashboardService with metric aggregation** - `7fabb77` (feat)
|
|
2. **Task 2: Dashboard API route and integration tests** - `5b1b4ee` (feat)
|
|
|
|
## Files Created/Modified
|
|
- `src/lib/services/dashboard-service.ts` - DashboardService with getRevenueMetrics, getOverdueMetrics, getSubscriberMetrics, getCashFlowSummary, getCollectorSummary, getDashboardSummary
|
|
- `src/app/api/dashboard/route.ts` - GET endpoint with read Report permission, optional startDate/endDate params
|
|
- `src/lib/__tests__/dashboard-service.test.ts` - 6 integration tests with comprehensive seeded data and cleanup
|
|
|
|
## Decisions Made
|
|
- Revenue metrics query Payment.createdAt for today/month ranges (system timestamp, not economic paymentDate)
|
|
- Cash flow follows FinancialReportService pattern: POSTED JE lines on leaf revenue/expense accounts with normal balance direction
|
|
- Collector summary uses PENDING remittance status (the Prisma enum for unverified remittances)
|
|
- All 5 metric methods run in parallel via Promise.all in getDashboardSummary for optimal performance
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Dashboard API ready for frontend consumption in 05-02
|
|
- All metric methods are independently callable for future widget/chart endpoints
|
|
- No blockers for next plan
