All data is stored in an SQLite3 database.
The server and game rules are implemented in Javascript. The game state is stored in the database as a JSON blob. The server runs on Node with the Express.js and Socket.io frameworks.
Redirect port 80 and 443 to 8080 and 8443:
sudo iptables -A PREROUTING -t nat -p tcp --dport 80 -j REDIRECT --to-ports 8080
sudo iptables -A PREROUTING -t nat -p tcp --dport 443 -j REDIRECT --to-ports 8443
Create SSL certificate with Let's Encrypt certbot, or self-signed with OpenSSL:
openssl req -nodes -new -x509 -keyout key.pem -out cert.pem
Configure the server using the .env file:
NODE_ENV=production
HTTP_PORT=8080
HTTPS_PORT=8443
SSL_KEY=/etc/letsencrypt/live/YOUR_DOMAIN/privkey.com
SSL_CERT=/etc/letsencrypt/live/YOUR_DOMAIN/fullchain.pem
MAIL_FROM="Your Site Name <notifications@YOUR_DOMAIN>"
MAIL_HOST=localhost
MAIL_PORT=25
If the HTTPS_PORT is missing, the server will only serve HTTP. If MAIL_HOST/PORT are not present, the server will not send notification emails.
