🚀 Getting Started

Prerequisites

Before you begin, ensure you have the following installed:

• Node.js (v18 or higher) - Download
• npm or yarn package manager
• Git - Download
• Expo CLI - npm install -g expo-cli
• EAS CLI - npm install -g eas-cli (for building APK)
• Physical Android/iOS device (for testing push notifications)

1️⃣ Clone the Repository

git clone https://github.com/mayurnaik32/SMR.git
cd SMR/ShareMyRide

2️⃣ Install Dependencies

Frontend (Mobile App)

# Navigate to ShareMyRide folder
cd ShareMyRide

# Install mobile app dependencies
npm install

Backend (API Server)

cd backend
npm install
cd ..

3️⃣ Setup Supabase Database

1. Create Supabase Project:

   • Go to https://supabase.com
   • Click "New Project"
   • Fill in project details
   • Wait for database provisioning (~2 minutes)

2. Run Database Migration:

   • Open Supabase Dashboard → SQL Editor
   • Copy ALL content from database/complete_schema_migration.sql
   • Paste into SQL Editor
   • Click "Run" button (or press Ctrl+Enter)
   • Wait for success message: ✅ Schema migration completed successfully!

3. Get Your Credentials:

   • Go to Settings → API
   • Copy Project URL and anon/public key
   • For backend, also copy service_role key (keep secret!)

4️⃣ Configure Environment Variables

Frontend Configuration

Update config/supabase.js:

import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_PROJECT_URL';
const supabaseAnonKey = 'YOUR_SUPABASE_ANON_KEY';

export const supabase = createClient(supabaseUrl, supabaseAnonKey);

Backend Configuration

Create backend/.env:

# Supabase Configuration
SUPABASE_URL=YOUR_SUPABASE_PROJECT_URL
SUPABASE_SERVICE_KEY=YOUR_SUPABASE_SERVICE_ROLE_KEY

# Server Configuration
PORT=3000
NODE_ENV=development

5️⃣ Update Backend URL for Device Testing

Update utils/notificationHelper.js (around line 5):

// For local testing on same machine:
const BACKEND_URL = 'http://localhost:3000';

// For testing on physical device (replace with your computer's IP):
// const BACKEND_URL = 'http://192.168.1.100:3000';

// Find your IP:
// Windows: Run 'ipconfig' in CMD, look for IPv4 Address
// Mac/Linux: Run 'ifconfig', look for inet address

6️⃣ Start the Application

Terminal 1: Start Backend Server

cd backend
node server.js

# Expected Output:
# ✅ Server running on http://localhost:3000

Keep this terminal running!

Terminal 2: Start Mobile App

Option A: Expo Go (Quick Testing - No Notifications)

npx expo start

# Scan QR code with Expo Go app
# ⚠️ Note: Push notifications won't work in Expo Go

Option B: Development Build (For Testing Notifications) ✅

# Connect Android device via USB with USB debugging enabled
npx expo run:android

# This will:
# 1. Build a development APK (5-10 minutes first time)
# 2. Install on connected device
# 3. Start Metro bundler
# ✅ Notifications WILL work!

---

📦 Building APK

Method 1: Local Build (Fastest) ⚡

Requirements:

• Android device connected via USB
• USB debugging enabled

Steps:

# 1. Enable USB debugging on Android:
#    Settings → About Phone → Tap "Build Number" 7 times
#    Settings → Developer Options → Enable "USB Debugging"

# 2. Connect device to computer via USB

# 3. Build and install:
npx expo run:android

# APK will be installed automatically

---

Method 2: EAS Build (Cloud Build) ☁️

Step 1: Setup EAS

# Install EAS CLI globally
npm install -g eas-cli

# Login to Expo account
eas login

# Initialize EAS
eas init

Step 2: Create EAS Configuration

Create eas.json:

{
  "build": {
    "development": {
      "developmentClient": true,
      "distribution": "internal",
      "android": {
        "buildType": "apk"
      }
    },
    "preview": {
      "distribution": "internal",
      "android": {
        "buildType": "apk"
      }
    },
    "production": {
      "android": {
        "buildType": "app-bundle"
      }
    }
  }
}

Step 3: Build APK

# Development build
eas build --profile development --platform android

# Preview build (for testing)
eas build --profile preview --platform android

# Production build (for Play Store)
eas build --profile production --platform android

---

🧪 Testing

Test Push Notifications

1. Build development APK (see above)
2. Install on physical device
3. Login to app
4. Go to: Profile → Notification Settings
5. Tap: "Send Test Notification"
6. Result: Notification should appear! 🎉

Test Backend API

# Health check
curl http://localhost:3000/health

# Expected: {"status":"ok"}

🐛 Troubleshooting

Push Notifications Not Working

Solutions:

• ✅ Use development build, NOT Expo Go
• ✅ Test on physical device, NOT emulator
• ✅ Check notification permissions are granted
• ✅ Verify backend server is running
• ✅ Check push token is saved in database

Backend Connection Failed

Solutions:

• ✅ Check backend is running: node backend/server.js
• ✅ Update backend URL in utils/notificationHelper.js
• ✅ Use your computer's IP address (not localhost) for device testing
• ✅ Ensure device and computer are on same WiFi network

Database Errors

Solutions:

• ✅ Re-run migration script in Supabase SQL Editor
• ✅ Check Supabase logs: Dashboard → Database → Logs
• ✅ Verify credentials in config files
