PR DESCRIPTION TEMPLATE + +```markdown +## GitHub Issue #20: Add QR Code Endpoint for Delivery Handoff Verification + +### Summary +Implemented `GET /api/v1/deliveries/:id/qrcode` endpoint that generates a secure QR code for physical delivery handoff verification. The QR code encodes a delivery ID alongside a cryptographically secure, time-limited verification token. + +### Security Design + +**Token Generation & Validity:** +- **Generation:** Cryptographically secure via `crypto.randomBytes(32).toString('hex')` — 256 bits of entropy, unpredictable +- **Scope:** Token only valid while delivery is in `ASSIGNED` or `IN_PROGRESS` status +- **Expiry:** Token expires 24 hours after generation +- **Persistence:** Token stored on Delivery record; enables server-side verification later +- **Security Property:** Single-handoff-use via status transition invalidation + time-based expiry + +**Verification Strategy (design for future `POST /api/v1/deliveries/:id/confirmHandoff`):** +- Recipient scans QR → sends token to confirmation endpoint +- Server verifies: token matches stored value, not expired, delivery still valid status +- Server marks delivery as `COMPLETED`, invalidates token +- Prevents QR code reuse; token invalid after handoff confirmed or 24h elapsed + +### Response Format + +**Chosen:** Base64-encoded PNG in JSON (not binary image) + +**Reasoning:** +- Consistent with existing API's JSON response format +- All existing endpoints return `{ status, data }` JSON +- Client can use in ``, save, share +- No special content-type negotiation required +- Aligns with API's JSON-first design + +**Example:** +```json +{ + "status": "success", + "data": { + "qrCode": "data:image/png;base64,iVBORw0KGgoAAAANSU..." + } +} +``` + +### Implementation Details + +**Architecture:** +- **Controller:** Thin — extracts `:id` param, calls service, returns JSON +- **Service:** Full business logic — validation, token generation, persistence, QR encoding +- **Model:** Schema additions — `verificationToken`, `tokenExpiresAt`, `handoffVerifiedAt` +- **Routing:** Follows existing pattern — `GET /api/v1/deliveries/:id/qrcode` + +**Dependencies Added:** +- `qrcode` (v1.5.3+) — popular, stable Node QR library +- `@types/qrcode` — TypeScript types + +**Error Handling:** +- 400 (BAD_REQUEST): Invalid delivery ID format +- 404 (NOT_FOUND): Delivery not found +- 409 (CONFLICT): Delivery not in valid state (not ASSIGNED/IN_PROGRESS) +- 500: Unexpected server error (token generation, QR encoding failure) + +### Testing + +**Unit Tests:** Service layer validation, token generation, persistence +**Integration

comprehensive end-to-end integration tests for the real-time driver location tracking feature via Socket.io WebSockets. + +**Key Characteristics:** +- **Real MongoDB:** Uses MongoMemoryServer for actual database operations (no mocks) +- **Typed Socket.io:** Full TypeScript support with strict event typing +- **Full Architecture Stack:** Tests Controller → Service → Model layers +- **Deduplication:** Validates Redis-based duplicate detection +- **Multi-client:** Tests room broadcasting and isolation +- **Error Handling:** Comprehensive payload validation tests +- **Concurrent Updates:** Tests race conditions and ordering + +--- + +## Test Architecture + +### Fixtures Created at Suite Start + +1. **Test Driver User** + - Email: `driver@test.local` + - Role: `driver` + -

`{ success, locationId?, error?, isDuplicate?, isStale? }` | Acknowledge receipt | + +### Room Structure + +- **Room Pattern:** `delivery:{deliveryId}` +- **Join Event:** `join_room` +- **Leave Event:** `leave_room` +- **Isolation:** Broadcasts only reach clients in the specific delivery room + +--- + +## Test Suites Breakdown + +### Suite 1: Socket Connection (4 tests) + +Verifies basic Socket.io connectivity and health checks. + +- ✅ Driver connects with userId in auth +- ✅ Recipient connects with userId in auth +- ✅ Each client gets unique socket ID +- ✅ Ping/pong health checks work + +### Suite 2: Delivery Room Joining (3 tests) + +Tests room subscription mechanics. + +- ✅ Client joins delivery room via `join_room` event +- ✅ Multiple clients can join same room +- ✅ Client can leave room via `leave_room` event + +### Suite 3: Driver Location Update Event (6 tests) + +Core broadcast functionality. + +- ✅ Broadcasts to all clients in delivery room +- ✅ Broadcast includes `receivedAt` ISO timestamp +- ✅ Driver gets `location_update_ack` with `locationId` +- ✅ Does NOT broadcast to clients outside room +- ✅ Persists to MongoDB with `isOfflineSync=false` +- ✅ Broadcasts exact coordinates sent by driver + +### Suite 4: Deduplication & Race Conditions (3 tests) + +Validates race condition prevention. + +- ✅ Rejects duplicate updates (same coords within TTL) +- ✅ Rejects stale updates (older than last processed) +- ✅ Accepts newer updates (later timestamp) + +**Mechanism:** +- Redis dedup key: `location:dedup:{driverId}:{deliveryId}:{timestamp}:{lat}:{lng}` +- Redis last update: `location:last:{driverId}:{deliveryId}` +- TTL: 60 seconds (configurable via `LOCATION_DEDUP_TTL_SECONDS`) + +### Suite 5: Payload Validation (12 tests) + +Comprehensive input validation. + +**Invalid Cases:** +- ❌ Missing `deliveryId` +- ❌ Invalid `deliveryId` (not ObjectId) +- ❌ Missing latitude +- ❌ Latitude > 90 or < -90 +- ❌ Missing longitude +- ❌ Longitude > 180 or < -180 +- ❌ `capturedAt = 0` +- ❌ `capturedAt` too far in future (>30s) +- ❌ `capturedAt` too old (>5 minutes) + +**Valid Cases:** +- ✅ Boundary coords: lat=90, lng=180 +- ✅ Boundary coords: lat=-90, lng=-180 +- ✅ High precision coords: 6 decimal places + +### Suite 6: Authentication & Authorization (2 tests) + +Verifies auth guards. + +- ✅ Rejects unauthenticated sockets +- ✅ Uses correct userId from socket.data for driverId + +### Suite 7: Offline Sync Integration (1 test) + +Tests offline sync batch processing. + +- ✅ `location_sync` event processes batch of offline updates + +### Suite 8: Multiple Deliveries (1 test) + +Verifies room isolation across deliveries. + +- ✅ Broadcasts are isolated per delivery room + +### Suite 9: Concurrent Connections (2 tests) + +Tests concurrent operations. + +- ✅ Handles rapid successive location updates +- ✅ Persists multiple updates with correct delivery association + +--- + +## MongoDB Persistence + +Each location update creates a `LocationUpdate` document: + +```typescript +{ + _id: ObjectId, + driverId: ObjectId, + deliveryId: ObjectId, + coordinates: { + lat: number, + lng: number + }, + capturedAt: Date, + isOfflineSync: false, // Live updates always false + status: 'pending', // Initial status + createdAt: Date, + updatedAt: Date +} +``` + +**Indexes Used:** +- `{ driverId: 1, status: 1, capturedAt: 1 }` +- `{

+### "Can't connect to MongoDB" +- MongoMemoryServer is auto-started in `beforeAll` +- Check that port 27017 is available +- Check disk space (first run downloads ~40MB binary) + +### "Timeout: Promise never resolved" +- Check that Socket.io server started on TEST_PORT +- Verify auth configuration on client +- Check for listener naming typos + +### "Dedup test fails intermittently" +- Redis connection may not be available +- Test uses fail-open behavior (allows duplicates if Redis down) +- Set `REDIS_URL` to mock or skip Redis tests + +### "Location not persisting" +- Check MongoDB connection in logs +- Verify `LocationUpdate` model can be imported +- Ensure service layer `processLiveUpdate` completes + +### "Room broadcast not received" +- Verify client joined room before broadcast +- Check room name matches: `delivery:{deliveryId}` format +- Ensure client registered listener BEFORE emitting + +--- + +## Architecture Alignment + +This test suite validates the following architecture: + +``` +Controller (locationHandler) + ↓ + ├→ Auth guard (socket.data.userId) + ├→ Payload validation + └→ Delegate to service + +Service (LocationService) + ↓ + ├→ Validate payload + timestamp + ├→ Redis dedup check + ├→ Redis stale check + ├→ Persist (Model layer) + └→ Broadcast via Socket.io + +Model (LocationUpdate) + ↓ + └→ MongoDB persistence with indexes +``` + +All three
