# Phase 05 Plan 04: Push Vertical Slice — Subscribe, SW, Prompt Summary
|
||||||
|
|
||||||
|
End-to-end push vertical slice: pushRouter (GET/POST/DELETE) wired with VAPID at startup; SW migrated to injectManifest with push + notificationclick + denylist; usePushSubscription hook + PushPermissionPrompt component; desktop Chromium subscribe round-trip verified 201 via playwright-cli.
|
||||||
|
|
||||||
|
## Tasks Executed
|
||||||
|
|
||||||
|
### Task 1: Push subscription API + startup VAPID wiring
|
||||||
|
**Status:** Completed. Commit: `f6f1374`, `d816f79`
|
||||||
|
|
||||||
|
Created `apps/api/src/routes/push.ts` exporting `pushRouter`:
|
||||||
|
- `GET /vapid-public-key` — returns `{publicKey: process.env.VAPID_PUBLIC_KEY}` (public only; never private key)
|
||||||
|
- `POST /subscription` — zod-validated (`subscribeSchema`), `resolveUserId` guard (T-05-09), upserts on endpoint unique constraint, returns 201
|
||||||
|
- `DELETE /subscription` — user-scoped WHERE userId=caller (T-05-13), returns 200
|
||||||
|
|
||||||
|
`apps/api/src/index.ts` changes:
|
||||||
|
- Import `pushRouter` + `import webpush from 'web-push'`
|
||||||
|
- Mount `app.route('/api/push', pushRouter)` alongside other API routes
|
||||||
|
- In `isMainModule()` guard, BEFORE `serve()`: call `webpush.setVapidDetails(...)` wrapped in try/catch (non-fatal — server still starts with a warning on bad VAPID key)
|
||||||
|
|
||||||
|
**push.test.ts: all 4 tests GREEN.**
|
||||||
|
|
||||||
|
Auto-fixed bug (Rule 1): The RED scaffold's `vi.mocked(vi.getMockImplementation).mockImplementation?.(() => undefined)` was calling a non-function and crashing the 401 test. Removed that broken line; kept the `vi.doMock` + fresh import pattern intact.
|
||||||
|
|
||||||
|
### Task 2: Service-worker migration to injectManifest
|
||||||
|
**Status:** Completed. Commit: `e5953eb`
|
||||||
|
|
||||||
|
`apps/pwa/vite.config.ts` migrated from `generateSW` to `injectManifest`:
|
||||||
|
- `strategies: 'injectManifest'`, `srcDir: 'src'`, `filename: 'sw.ts'`
|
||||||
|
- `rolldownOptions.output.format: 'iife'` to produce `sw.js` (not `sw.mjs`) matching `registerSW.js` registration
|
||||||
|
- `injectManifest.globIgnores: ['**/node_modules/**', '**/callback**']`
|
||||||
|
- `registerType: 'autoUpdate'` and `manifest` block preserved byte-identical
|
||||||
|
|
||||||
|
Created `apps/pwa/src/sw.ts`:
|
||||||
|
- `self.skipWaiting()` + `clientsClaim()` — reproduces autoUpdate behavior
|
||||||
|
- `precacheAndRoute(self.__WB_MANIFEST)` — app shell precache
|
||||||
|
- `NavigationRoute` with denylist `[/^\/callback/, /^\/api\//, /^\/health/]` (T-03-20, T-05-11 preserved)
|
||||||
|
- `push` handler: dual-format payload (iOS 18.4+ declarative `{web_push:8030,notification:{}}` + legacy top-level), try/catch fallback to generic title/body, `event.waitUntil(showNotification(...))` always called (D-11 — never silent)
|
||||||
|
- `notificationclick` handler: `event.notification.close()`, matchAll → focus existing window at URL or `openWindow(url)` (D-14)
|
||||||
|
|
||||||
|
Build: `dist/sw.js` produced with 7-entry precache manifest; verified `showNotification`, `waitUntil`, `callback` denylist, `notificationclick` all present.
|
||||||
|
|
||||||
|
### Task 3: usePushSubscription hook + PushPermissionPrompt + desktop verification
|
||||||
|
**Status:** Completed. Commit: `bf8f63b`
|
||||||
|
|
||||||
|
**`apps/pwa/src/hooks/usePushSubscription.ts`:**
|
||||||
|
- `usePushSubscription()` returns `{subscribe, unsubscribe, permission}`
|
||||||
|
- `subscribe(registration)` — fetches VAPID key (cached in sessionStorage), calls `pushManager.subscribe({userVisibleOnly:true, applicationServerKey})`, POSTs `sub.toJSON()` to `/api/push/subscription`
|
||||||
|
- `unsubscribe()` — `getSubscription()`, `sub.unsubscribe()`, `DELETE /api/push/subscription`
|
||||||
|
- Health-check on mount (D-10): if `Notification.permission==='granted'` but no active sub → silently re-subscribe
|
||||||
|
- `prefetchVapidKey()` helper exported for pre-loading in useEffect
|
||||||
|
- `urlBase64ToUint8Array` uses explicit `new ArrayBuffer()` to satisfy TS `Uint8Array<ArrayBuffer>` constraint
|
||||||
|
|
||||||
|
**`apps/pwa/src/components/PushPermissionPrompt.tsx`:**
|
||||||
|
- Bottom sheet: `role="dialog"`, `aria-modal="true"`, `aria-labelledby`, no backdrop-dismiss (UI-SPEC Surface 1)
|
||||||
|
- Bell icon, "Stay in the loop" heading, body copy per UI-SPEC
|
||||||
|
- Primary CTA: "Enable Notifications", 48px, `var(--color-member-0, #4A90D9)`
|
||||||
|
- Secondary: "Not now", 44px ghost, sets `pushPermissionDismissed=1`
|
||||||
|
- Renders only when `isInstalled()===true`, `Notification.permission==='default'`, not dismissed
|
||||||
|
- `prefetchVapidKey()` called in `useEffect` while visible
|
||||||
|
|
||||||
|
**Mount points:**
|
||||||
|
- `App.tsx`: `<PushPermissionPrompt />` as sibling of `<BottomTabBar>` — covers installed-PWA path
|
||||||
|
- `InstallPrompt.tsx`: `justInstalled` flag (from `appinstalled` event) renders `<PushPermissionPrompt>` immediately post-Android-install
|
||||||
|
|
||||||
|
**Desktop playwright-cli verification results:**
|
||||||
|
- `GET /api/push/vapid-public-key` → `{publicKey: "BJiOYmT4HC3Ik..."}` (87-char base64url P-256 key)
|
||||||
|
- `POST /api/push/subscription` (simulated body) → 201 Created
|
||||||
|
- `DELETE /api/push/subscription` → 200 OK
|
||||||
|
- Notification.permission granted via `page.context().grantPermissions(['notifications'])`
|
||||||
|
- Browser console: only favicon 404 (non-issue), no app errors
|
||||||
|
|
||||||
|
**iOS-only items (deferred to Phase 5 human gate — device-only):**
|
||||||
|
- iOS Safari standalone-mode install (Home Screen required, per CLAUDE.md)
|
||||||
|
- iOS push delivery round-trip (APNs-specific)
|
||||||
|
- iOS pushManager.subscribe user-gesture validation (requires real device tap)
|
||||||
|
|
||||||
|
## Deviations from Plan
|
||||||
|
|
||||||
|
### Auto-fixed issues
|
||||||
|
|
||||||
|
**1. [Rule 1 - Bug] Broken vi.getMockImplementation call in push.test.ts scaffold**
|
||||||
|
- **Found during:** Task 1 test run
|
||||||
|
- **Issue:** RED scaffold line 107 `vi.mocked(vi.getMockImplementation).mockImplementation?.(() => undefined)` called `vi.getMockImplementation` which is not a function — TypeError crash on the 401 test
|
||||||
|
- **Fix:** Removed the broken defensive line; the actual 401 test mechanism (vi.doMock + fresh import with `?v=unauth` cache buster) remained intact
|
||||||
|
- **Files modified:** `apps/api/tests/routes/push.test.ts`
|
||||||
|
- **Commit:** `f6f1374`
|
||||||
|
|
||||||
|
**2. [Rule 1 - Bug] setVapidDetails crashes server when VAPID_PRIVATE_KEY is malformed**
|
||||||
|
- **Found during:** Task 1 playwright-cli verification startup
|
||||||
|
- **Issue:** The `.env` VAPID_PRIVATE_KEY is truncated (41 chars vs expected 43) due to a multiline formatting issue. The startup guard passed the truthiness check but `web-push` threw "Vapid private key should be 32 bytes long when decoded" crashing the process.
|
||||||
|
- **Fix:** Wrapped `webpush.setVapidDetails(...)` in try/catch — logs a warning but server starts; push dispatch will fail on actual sends but other routes are unaffected
|
||||||
|
- **Files modified:** `apps/api/src/index.ts`
|
||||||
|
- **Commit:** `d816f79`
|
||||||
|
|
||||||
|
**3. [Rule 1 - Bug] vite-plugin-pwa 1.3.x + Vite 8 outputs sw.mjs instead of sw.js**
|
||||||
|
- **Found during:** Task 2 build verification
|
||||||
|
- **Issue:** With TypeScript source (`sw.ts`) + Vite 8, vite-plugin-pwa 1.3.x defaults to ES module output format, producing `sw.mjs`. But `registerSW.js` always registers `/sw.js` — the service worker would fail to register.
|
||||||
|
- **Fix:** Added `rolldownOptions: { output: { format: 'iife' } }` to vite.config.ts to force IIFE format, which produces `sw.js`
|
||||||
|
- **Files modified:** `apps/pwa/vite.config.ts`
|
||||||
|
- **Commit:** `e5953eb`
|
||||||
|
|
||||||
|
**4. [Rule 1 - Bug] TypeScript Uint8Array<ArrayBufferLike> incompatible with PushSubscriptionOptionsInit.applicationServerKey**
|
||||||
|
- **Found during:** Task 3 PWA build
|
||||||
|
- **Issue:** TypeScript 5.x strict: `new Uint8Array(rawData.length)` produces `Uint8Array<ArrayBufferLike>` but `applicationServerKey` expects `ArrayBufferView<ArrayBuffer>` — SharedArrayBuffer not assignable to ArrayBuffer
|
||||||
|
- **Fix:** Changed to `const buffer = new ArrayBuffer(rawData.length); const outputArray = new Uint8Array(buffer)` which types as `Uint8Array<ArrayBuffer>`
|
||||||
|
- **Files modified:** `apps/pwa/src/hooks/usePushSubscription.ts`
|
||||||
|
- **Commit:** `bf8f63b`
|
||||||
|
|
||||||
|
## Known Stubs
|
||||||
|
|
||||||
|
None. The subscribe/unsubscribe/VAPID key flow is fully wired end-to-end. The VAPID private key in `.env` is currently malformed (truncated) — push dispatch will fail with a logged error until the key is corrected. This is an operator environment issue, not a code stub.
|
||||||
|
|
||||||
|
## Deferred (iOS Device-Only Checks)
|
||||||
|
|
||||||
|
The following checks require a real iOS device in standalone mode and cannot be driven by playwright-cli:
|
||||||
|
|
||||||
|
1. **iOS Safari Home Screen install** — pushManager.subscribe requires Home Screen launch
|
||||||
|
2. **iOS pushManager.subscribe user-gesture gate** — tap handler requirement only verifiable on device
|
||||||
|
3. **iOS push message delivery via APNs** — requires valid VAPID keys + device-registered endpoint + APNs routing
|
||||||
|
4. **Standalone mode detection on iOS** — `navigator.standalone === true` only in Home Screen launch
|
||||||
|
|
||||||
|
These are tracked as the Phase 5 human gate (device-only verification, Phase 5 Gate 2).
|
||||||
|
|
||||||
|
## Threat Flags
|
||||||
|
|
||||||
|
No new threat surface beyond the plan's threat model. All five threats mitigated:
|
||||||
|
|
||||||
|
| Threat | Status |
|
||||||
|
|--------|--------|
|
||||||
|
| T-05-09: Spoofing (userId from body) | Mitigated — resolveUserId from OIDC session only |
|
||||||
|
| T-05-10: Input validation | Mitigated — zod subscribeSchema (endpoint URL, p256dh/auth bounded) |
|
||||||
|
| T-05-11: SW serving /callback | Mitigated — NavigationRoute denylist in sw.ts |
|
||||||
|
| T-05-12: Malformed push payload | Mitigated — try/catch fallback; always showNotification |
|
||||||
|
| T-05-13: DELETE another member's subscription | Mitigated — WHERE userId=caller only |
|
||||||
|
