Getting Started

Production Deployment

For production deployment, you need to configure a reverse proxy (nginx, Caddy, etc.) to route API requests to the backend:

Example nginx configuration:

server {
    listen 80;
    server_name your-domain.com;
    
    location /api/ {
        proxy_pass http://backend:4000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
    
    location /mapPool {
        proxy_pass http://backend:4000/mapPool;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

    location / {
        proxy_pass http://frontend:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}
