Product Roadmap Implementation Summary ​

This document summarizes the implementation of all roadmap features for Lager Guru.

✅ Implementation Status ​

All roadmap features have been successfully implemented and integrated into the application.

1. Barcode Scanning Module ✅ ​

Implementation Details ​

Component: src/components/ui/BarcodeScanner.tsx

  • Uses @zxing/browser library (BrowserMultiFormatReader)
  • Supports multiple camera devices
  • Automatic camera selection and switching
  • Fallback UI for unsupported browsers or denied permissions
  • Continuous or single-scan modes

Integration Points:

  1. Admin Dashboard - Create Shipment Form (src/components/admin/CreateShipmentDialog.tsx)

    • Scanner button next to "Bezeichnung" field
    • Supports JSON barcode format: {name, from_zone_id, to_zone_id, driver_id, priority}
    • Also supports plain text (fills name field)
    • Auto-fills form fields when barcode is detected

  2. Worker Dashboard - Create Pickup Request (src/components/worker/CreatePickupRequest.tsx)

    • Scanner button in form
    • Parses JSON or plain text
    • Auto-fills shipment name

  3. Admin Dashboard - Shipment Management (src/components/admin/ShipmentManagement.tsx)

    • "Barcode scannen" button in shipment list
    • Looks up existing shipments by order_number or id
    • Opens shipment detail modal when found

Features ​

  • ✅ Camera permission handling
  • ✅ Multiple device support
  • ✅ Error handling and user feedback
  • ✅ Automatic form field population
  • ✅ Shipment lookup by barcode

Usage Example ​

typescript
<BarcodeScanner
  active={isScannerOpen}
  onDetected={(value) => {
    // Handle detected barcode
    console.log("Scanned:", value);
  }}
  onClose={() => setIsScannerOpen(false)}
  continuous={false} // Stops after first scan
/>

2. GPS + Driver Location Tracking ✅ ​

Database Schema ​

Table: public.driver_locations

  • driver_id (UUID, PK, references profiles.id)
  • lat (double precision)
  • lng (double precision)
  • updated_at (timestamptz)

Migration: supabase/migrations/20250201000001_driver_locations.sql

RLS Policies:

  • Drivers can upsert their own location
  • Admins and workers can read all driver locations

Implementation ​

Driver Dashboard (src/pages/driver/DriverDashboard.tsx):

  • "Share My Location" toggle switch
  • Uses navigator.geolocation.watchPosition()
  • Updates location every position change (with maximumAge: 5000ms)
  • Stores location in driver_locations table via Supabase upsert
  • Clears location when toggle is off
  • Persists toggle state in localStorage

Admin Dashboard - Live Map (src/components/admin/DriverLiveMap.tsx):

  • Real-time map using MapLibre GL
  • Displays driver markers with status badges
  • Realtime subscription to driver_locations table
  • Shows driver name, online status, working status
  • Auto-updates when drivers move

Features ​

  • ✅ Optional location sharing (opt-in)
  • ✅ Real-time location updates
  • ✅ Privacy: drivers control their own location sharing
  • ✅ Live map visualization for admins
  • ✅ Realtime updates via Supabase

Usage ​

Drivers enable location sharing via toggle in their dashboard. Location is automatically updated and visible to admins on the live map.

3. AI-Based Suggestions ✅ ​

Implementation ​

Module: src/lib/ai.ts

Functions:

  • suggestDriver(shipments, drivers, options?) - Returns best driver suggestion
  • suggestZone(shipments, zones) - Returns best zone suggestion

Algorithm (Heuristic-based, no external API):

Driver Suggestion Factors:

  • Online status (+50 points)
  • Working status (+20 points)
  • Pause status (-20 points)
  • Active shipment count (-10 per shipment)
  • Last seen timestamp (recent activity bonus)
  • GPS location sharing bonus (+5 if enabled)
  • Distance calculation ready (Haversine formula implemented, requires zone coordinates)

Zone Suggestion Factors:

  • Utilization percentage (prefers lower utilization)
  • Inbound shipment count (avoids overloaded zones)
  • Capacity thresholds (penalty if >85% utilization)

Integration ​

Admin Create Shipment Form (src/components/admin/CreateShipmentDialog.tsx):

  • Shows suggested driver with reason (e.g., "online, im Einsatz, frei verfügbar")
  • Shows suggested zone with utilization info
  • "Übernehmen" button to apply suggestion
  • Updates dynamically when form fields change

Features ​

  • ✅ Pure heuristic logic (no external API)
  • ✅ Real-time suggestions based on current data
  • ✅ Explanatory reasons for each suggestion
  • ✅ One-click application of suggestions
  • ✅ Distance calculation ready (when zone coordinates are added)

Example Output ​

typescript
{
  id: "driver-uuid",
  score: 85,
  reason: "online, im Einsatz, frei verfügbar, Standortfreigabe aktiv"
}

4. External REST API (Supabase Edge Functions) ✅ ​

Implementation ​

Location: supabase/functions/api/index.ts

Endpoints:

  1. GET /api/shipments

    • Query parameters: ?status=pending (optional)
    • Returns: List of shipments (max 100)
    • Auth: Required (JWT)

  2. POST /api/shipments

    • Body: {name, from_zone_id, to_zone_id, driver_id?, priority?, status?}
    • Returns: Created shipment with id and order_number
    • Auth: Admin only

  3. GET /api/zones

    • Returns: List of all zones with capacity info
    • Auth: Required (JWT)

  4. GET /api/driver-status

    • Returns: Driver profiles with location data
    • Auth: Admin or Worker only

Shared Utilities:

  • _shared/auth.ts - JWT validation
  • _shared/db.ts - Supabase admin client
  • _shared/response.ts - JSON response helpers
  • _shared/rateLimit.ts - Rate limiting template

Client Library: src/lib/api.ts

  • fetchShipmentsFromEdge(status?)
  • createShipmentViaEdge(payload)
  • fetchDriverStatusViaEdge()

Features ​

  • ✅ JWT authentication
  • ✅ Rate limiting template
  • ✅ Error handling
  • ✅ TypeScript types
  • ✅ React integration examples

Usage Example ​

typescript
import { fetchShipmentsFromEdge, createShipmentViaEdge } from "@/lib/api";

// Fetch shipments
const shipments = await fetchShipmentsFromEdge("pending");

// Create shipment
const result = await createShipmentViaEdge({
  name: "Palette Elektronik",
  from_zone_id: "zone-uuid",
  to_zone_id: "zone-uuid-2",
  priority: "high"
});

5. Advanced Reporting & Analytics ✅ ​

Database Views ​

Migration: supabase/migrations/20250201000002_analytics_views.sql

Views Created:

  1. shipments_per_hour_last_24h

    • Hourly buckets with total and completed counts
    • Last 24 hours only

  2. driver_performance

    • Completed deliveries count
    • Active deliveries count
    • Average minutes to complete

  3. time_to_complete_metrics

    • Average completion time (minutes)
    • P50 (median) completion time
    • P90 completion time

Existing Views (from previous migrations):

  • zones_avg_utilization - Average zone utilization percentage

Implementation ​

Page: src/pages/admin/Analytics.tsx

Components:

  • src/components/admin/analytics/AnalyticsCards.tsx - KPI cards
  • src/components/admin/analytics/OrdersPerHourChart.tsx - Line chart (Recharts)
  • src/components/admin/analytics/StatusSplitChart.tsx - Pie chart (Recharts)
  • src/components/admin/analytics/DriverLeaderboard.tsx - Table with performance metrics

Charts:

  • Orders per hour (last 24h) - Line chart
  • Completed vs In-Transit - Pie chart
  • Driver performance leaderboard - Table
  • Average zone utilization - Card
  • Time-to-complete metrics - Cards (avg, P50, P90)

Features ​

  • ✅ Real-time data from SQL views
  • ✅ Interactive charts (Recharts)
  • ✅ Performance metrics
  • ✅ Driver leaderboard

Edge Cases Handled ​

  1. Barcode Scanner:

    • Permission denied → Error message with instructions
    • Unknown barcode format → Treated as plain text
    • Invalid JSON → Graceful fallback

  2. GPS Location:

    • Geolocation not supported → Error message
    • Permission denied → Toggle disabled
    • Location timeout → Error handling
    • Network errors → Retry logic

  3. AI Suggestions:

    • No drivers available → Null suggestion with message
    • No zones available → Null suggestion
    • All drivers offline → Still suggests best option
    • High utilization → Suggests alternative zones

  4. Edge Functions:

    • Invalid JWT → 401 response
    • Missing fields → 422 validation error
    • Rate limit exceeded → 429 response
    • Database errors → 400/500 with message

  5. Analytics:

    • No data → Empty state
    • View errors → Error message
    • Missing views → Graceful degradation

Future Enhancements ​

  1. Zone Coordinates:

    • Add lat/lng to zones table
    • Enable distance-based driver suggestions
    • Show zone locations on map

  2. Barcode Templates:

    • Predefined barcode formats
    • Custom field mapping
