Running locally

No build step, just static files.

git clone https://gitea.nalakath.org/aman/conways-game-of-life.git
cd conways-game-of-life
python3 -m http.server 8080

Open http://localhost:8080.

Deploying (WIP)

Nginx / Caddy, serving the repo directly

server {
    listen 80;
    server_name life.example.com;
    root /srv/www/conway_gameoflife;
    index index.html;

    location / {
        try_files $uri $uri/ /index.html;
    }
}

life.example.com {
    root * /srv/www/conway_gameoflife
    file_server
    try_files {path} /index.html
}

Gitea Actions, copying files to a server path or object storage. There's a basic ci.yml in .gitea/workflows/ that checks required files exist and that the JS is syntactically valid. Extend it for your own deploy target.

All paths are relative (./style.css, ./js/app.js), so it works at the domain root or under a subpath like /apps/life/. Keep index.html, style.css, and js/ together.

Ideas for later

Infinite canvas with panning
Better touch controls for mobile
Rotate/mirror patterns before stamping
