Technical Implementation

Mobile App (React Native)

// Real-time order tracking component
import React, { useEffect, useState } from 'react';
import { View, Text } from 'react-native';
import MapView, { Marker } from 'react-native-maps';
import io from 'socket.io-client';

const OrderTracking = ({ orderId }) => {
  const [driverLocation, setDriverLocation] = useState(null);
  const [orderStatus, setOrderStatus] = useState('preparing');

  useEffect(() => {
    const socket = io('https://api.fooddelivery.com');
    
    socket.emit('trackOrder', orderId);
    
    socket.on('locationUpdate', (location) => {
      setDriverLocation(location);
    });
    
    socket.on('statusUpdate', (status) => {
      setOrderStatus(status);
    });
    
    return () => socket.disconnect();
  }, [orderId]);

  return (
    <View style={{ flex: 1 }}>
      <MapView
        style={{ flex: 1 }}
        region={{
          latitude: driverLocation?.latitude || 0,
          longitude: driverLocation?.longitude || 0,
          latitudeDelta: 0.01,
          longitudeDelta: 0.01,
        }}
      >
        {driverLocation && (
          <Marker
            coordinate={driverLocation}
            title="Delivery Driver"
          />
        )}
      </MapView>
      <Text>Order Status: {orderStatus}</Text>
    </View>
  );
};

Backend API (Node.js + Express)

// Real-time order management
const express = require('express');
const http = require('http');
const socketIo = require('socket.io');
const Order = require('./models/Order');

const app = express();
const server = http.createServer(app);
const io = socketIo(server);

// Order status update endpoint
app.put('/api/orders/:id/status', async (req, res) => {
  try {
    const { id } = req.params;
    const { status, driverLocation } = req.body;
    
    const order = await Order.findByIdAndUpdate(
      id,
      { status, driverLocation },
      { new: true }
    );
    
    // Emit real-time update to customer
    io.to(`order_${id}`).emit('statusUpdate', status);
    
    if (driverLocation) {
      io.to(`order_${id}`).emit('locationUpdate', driverLocation);
    }
    
    res.json(order);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

// Socket connection handling
io.on('connection', (socket) => {
  socket.on('trackOrder', (orderId) => {
    socket.join(`order_${orderId}`);
  });
});

Database Schema (MongoDB)

// Order model
const orderSchema = new mongoose.Schema({
  customer: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
  restaurant: { type: mongoose.Schema.Types.ObjectId, ref: 'Restaurant' },
  driver: { type: mongoose.Schema.Types.ObjectId, ref: 'Driver' },
  items: [{
    menuItem: { type: mongoose.Schema.Types.ObjectId, ref: 'MenuItem' },
    quantity: Number,
    customizations: [String],
    price: Number
  }],
  totalAmount: Number,
  status: {
    type: String,
    enum: ['placed', 'confirmed', 'preparing', 'ready', 'picked_up', 'delivered'],
    default: 'placed'
  },
  deliveryAddress: {
    street: String,
    city: String,
    coordinates: {
      latitude: Number,
      longitude: Number
    }
  },
  paymentMethod: String,
  estimatedDeliveryTime: Date,
  actualDeliveryTime: Date
}, { timestamps: true });
