Summary (AI generated)

  • Extended GET /statistics/app/:app_id/native_usage with activeDevices (period distinct counts by platform) and dailyPlatformActive (daily Android/iOS totals).
  • Added read_native_active_devices_summary RPC + Cloudflare Analytics query for period-level distinct active devices.
  • Native dashboard tab (/app/:appId/native) now shows:
    • Fixed last 30 days KPI row: Android / iOS / total active devices
    • Selected period KPI row (respects ?days= / period selector) with period-over-period evolution badges
    • Android vs iOS daily active-device trend chart above the existing native build mix chart
  • Added unit tests for frontend/backend helpers and updated statistics integration + Playwright coverage.

Motivation (AI generated)

The Native dashboard tab only showed the native build version-mix chart. App owners needed at-a-glance active-device counts by platform (Android, iOS, total) and a clearer Android vs iOS trend for the selected period.

Business Impact (AI generated)

Improves console usability for app owners monitoring native adoption and platform mix without digging into charts. Makes platform health visible earlier in the workflow, which should reduce support back-and-forth and help teams spot iOS/Android skew faster.

Active device definition (AI generated)

Active device = a distinct device_id with at least one row in device_usage during the period (same source as the existing native build chart). Daily trend values are distinct devices per day per platform; period KPI totals are distinct devices across the full window (not summed daily counts).

Test Plan (AI generated)

  • bunx vitest run tests/native-device-stats.unit.test.ts
  • bunx vitest run tests/translation-queue.unit.test.ts
  • CI: backend statistics.test.ts (native_usage summary fields)
  • CI: Playwright app-dashboard-tabs.spec.ts (KPI labels visible on Native tab)
  • Manual: open /app/<appId>/native, verify KPI cards load for 1/3/7/30-day periods and match chart scale

Visual changes (AI generated)

UI layout adds KPI card rows and a platform trend chart above the existing chart. A product screenshot should be captured before human merge.

Review Change Stack

📝 Walkthrough

Walkthrough

Added native active-device analytics across storage, backend statistics, dashboard KPIs, platform trend charts, localization, and tests. The implementation supports Android, iOS, Electron, unknown, and total activity data for selected periods and 30-day summaries.

Changes

Native active-device analytics

Layer / File(s) Summary
Active-device contracts and storage
supabase/functions/_backend/utils/types.ts, supabase/migrations/..., supabase/functions/_backend/utils/*
Added native active-device types, an authorized Supabase summary function, Cloudflare Analytics Engine queries, and backend source selection.
Native usage aggregation and response
supabase/functions/_backend/public/statistics/index.ts
Combined version usage with active-device summaries and returned platform totals plus daily platform activity.
Dashboard data and native analytics UI
src/services/nativeDeviceStats.ts, src/services/chartDataService.ts, src/components/dashboard/*, messages/en.*
Added normalization and aggregation helpers, 30-day summary loading and caching, KPI cards, Android/iOS trend charts, and localization strings.
Native analytics validation
tests/*, playwright/e2e/app-dashboard-tabs.spec.ts
Added helper, backend aggregation, response-field, count, daily-total, and dashboard visibility assertions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 93515

Native dashboard KPIs and trends can show stale, inflated, misleading, or silently zero values. These material analytics regressions should be corrected before merge.

Compare equivalent periods for the evolution badges.

Lines 580-582 compare the first and latest non-zero daily values. The cards show distinct active devices for the whole selected period, so this badge is not a period-over-period value. Fetch the preceding equivalent period and compare its period-level active-device summaries.

The PR objective specifies period-over-period badges.

Discard stale 30-day summary responses.

loadThirtyDaySummary writes this result without checking requestToken or the requested app ID. If the user changes app or period while this request is pending, an older response can overwrite rawThirtyDayChartData and show another app’s KPI values. Capture the app ID and a request token before the request, then validate both before assigning state or caching the result.

Query distinct devices by date and platform for dailyPlatformActive. readNativeVersionUsage groups device_usage by date, platform, and version_build, then buildDailyPlatformActiveTotals sums those bucket counts. If one device reports two builds on the same date and platform, the daily total counts it twice. Use COUNT(DISTINCT blob1) grouped only by date and platform for this field.

Propagate Analytics Engine failures from readNativeActiveDevicesSummaryCF.

When DEVICE_USAGE is configured and either runQueryToCFA call fails, this helper catches the error and returns []. summarizeNativeActiveDevices([]) then returns zero values for every active-device KPI, so the statistics route returns success instead of its existing cannot_get_app_statistics error response. Let the error propagate to getNativeVersionUsage and the route boundary.

Confidence score: 2/5

  • supabase/functions/_backend/utils/cloudflare.ts converts Analytics Engine failures into empty results, causing active-device KPIs to appear as zero instead of returning an error—re-throw the logged error so the statistics route preserves failure visibility.
  • supabase/functions/_backend/public/statistics/index.ts and src/services/nativeDeviceStats.ts can count one device multiple times when it reports multiple builds or native versions on a day, inflating daily active-device trends—aggregate by distinct device and platform per day and use that data in the fallback.
  • src/components/dashboard/DevicesStats.vue can let a pending request from the previous app overwrite the newly selected app’s KPI state, particularly after a primary-request failure—cancel or identify stale requests before applying responses.
  • src/components/dashboard/DevicesStats.vue presents first-to-last non-zero daily values as period evolution and may use the latest daily count as a period-distinct total, producing misleading badges—retain the preceding equal-length period and leave the KPI unavailable when no distinct period total exists.

P1: Re-throw the Analytics Engine error after logging it. Returning an empty array converts a failed active-device query into successful zero-valued KPIs and prevents the statistics route from returning its error response.

P2: When a device reports multiple native versions in one day, this fallback counts it once per version, so daily active-device KPIs and trends can be inflated. Use the API’s dailyPlatformActive distinct-device data rather than deriving platform totals from version buckets.

P3: These two interfaces are dead code in types.ts. Nothing imports NativeActiveDevicesSummary or NativeDailyPlatformActive from this file — statistics/index.ts and src/services/nativeDeviceStats.ts each declare their own identical copies. Remove them here (keep NativeActiveDevicesByPlatformRow, which stats.ts/cloudflare.ts/supabase.ts do import) to avoid a duplicate source of truth for the API shape.

P3: The new native-* keys are inserted between active_users_by_native_version and add-an-app-to-get-started, breaking local alphabetical order (native-* sorts after add-*) and splitting them off from the existing native-* key cluster (native-dependencies, native-observe-*) grouped together near the end of the file. Move these eight keys next to the other native-* entries so related keys stay together.
