🚀 Production Deployment

Using Apache

<VirtualHost *:80>
    ServerName system.local
    DocumentRoot /var/www/project
    <Directory /var/www/project>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Using Nginx

server {
    listen 80;
    server_name system.local;
    root /var/www/project;
    
    location ~\.php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

📊 Performance

  • Page Load: < 3 seconds (on 10 Mbps connection)
  • API Response: < 500ms for most endpoints
  • Map Rendering: Real-time interactivity
  • Scoring Computation: < 1 second for 100 households

🛠️ Development Guide

Adding New Endpoint

  1. Create new file in /api/ folder: your_endpoint.php
  2. Include config.php for database access
  3. Use requireLogin() or requireRole() for access control
  4. Return JSON response

Example:

<?php
header('Content-Type: application/json');
require_once 'config.php';

requireRole(['Admin', 'Petugas']);

// Your code here

die(json_encode(['success' => true, 'data' => $result]));
?>

Modifying Frontend

  1. Edit js/app.js for logic changes
  2. Edit css/style.css for styling
  3. Edit index.html for structure/layout
  4. Refresh browser to see changes (no build required)

🐛 Troubleshooting

Login Issues

  • Verify email: admin@system.local
  • Verify password: admin123
  • Check browser cookies are enabled
  • Clear cache and try again

Map Not Loading

  • Check browser console for errors (F12)
  • Verify internet connection (for Leaflet CDN)
  • Try refreshing page

Database Issues

  • Ensure /db/ folder has write permissions
  • Check PHP error logs
  • Delete db/markers.db to reset (will lose data)

Performance Issues

  • Check browser performance (F12 > Performance tab)
  • Monitor server CPU/memory usage
  • Consider adding pagination for large datasets
