Option 4: Manual Setup

# 1. Clone and install dependencies
git clone <repository-url>
cd CookMate
npm install
cd backend/functions && npm install && cd ../..
cd frontend && npm install && cd ..

# 2. Setup environment file
cp backend/functions/.env.template backend/functions/.env

# 3. Add your GROQ API key (optional but recommended)
# Edit backend/functions/.env and replace 'your_groq_api_key_here' with your actual key
# Get free key: https://console.groq.com/

# 4. Start the servers

🆘 Need Help?

• Setup script not running? Use .\setup.bat (Windows) or ./setup.sh (Mac/Linux) to run local scripts
• Backend not starting? Check that Node.js is installed: node --version
• Port already in use? Kill processes using ports 5001 or 5173
• AI not responding? Add your GROQ_API_KEY to .env

🛠️ Troubleshooting

Common Issues & Solutions

1. "node: command not found" or "npm: command not found"

• Problem: Node.js is not installed
• Solution: Install Node.js from https://nodejs.org/ (LTS version recommended)
• Verify: Run node --version and npm --version to confirm installation

2. Port 5000, 5001, or 8080 already in use

• Problem: Another process is using the required ports for Firebase emulators
• Solution:

  # Windows
  netstat -ano | findstr :5000
  netstat -ano | findstr :5001
  netstat -ano | findstr :8080
  taskkill /PID <PID_NUMBER> /F
  
  # Mac/Linux  
  lsof -ti:5000 | xargs kill -9
  lsof -ti:5001 | xargs kill -9
  lsof -ti:8080 | xargs kill -9

3. "Cannot find module" errors

• Problem: Dependencies not installed properly
• Solution:

  # Clean install
  rm -rf node_modules package-lock.json
  rm -rf backend/functions/node_modules backend/functions/package-lock.json  
  rm -rf frontend/node_modules frontend/package-lock.json
  
  # Re-run setup
  ./setup.sh    # Mac/Linux
  setup.bat     # Windows

4. Backend server won't start

• Problem: Missing .env file or invalid configuration
• Solution:

  # Check if .env exists
  ls backend/functions/.env
  
  # If missing, create from template
  cp backend/functions/.env.template backend/functions/.env
  
  # Verify Node.js version (should be 16+)
  node --version

5. AI not responding or giving generic responses

• Problem: Missing or invalid GROQ API key
• Solution:
  1. Get free API key from https://console.groq.com/
  2. Edit backend/functions/.env
  3. Replace your_groq_api_key_here with your actual key
  4. Restart the backend server

6. Frontend build errors

• Problem: Node modules corrupted or version conflicts
• Solution:

  cd frontend
  rm -rf node_modules package-lock.json
  npm install
  npm run dev

7. Firebase authentication not working

• Problem: CORS issues or invalid Firebase config
• Solution:
  1. Check browser console for CORS errors
  2. Ensure Firebase project allows your domain
  3. Verify Firebase config in frontend/src/firebase.js

8. Database permission errors

• Problem: Firestore security rules blocking access
• Solution:
  • For development, ensure you're signed in
  • Check Firebase Console → Firestore → Rules
  • Test with a simple read operation first

Still Need Help?

1. Check the logs: Look at terminal output for specific error messages
2. Verify prerequisites: Node.js 16+, npm, Git
3. Fresh start: Delete node_modules folders and reinstall
4. Check versions: Ensure all dependencies are compatible

Environment Requirements

• Node.js: Version 16.0 or higher
• npm: Version 7.0 or higher
• Operating System: Windows 10+, macOS 10.14+, or Linux
• Browser: Chrome 90+, Firefox 88+, Safari 14+, or Edge 90+
