Granian serves the compiled SPA assets directly in Rust: hashed js/wasm/css under /static (the release build uses --public-url /static/) and the card images under /assets, configured with the GRANIAN_STATIC_PATH_ROUTE/MOUNT/ DIR_TO_FILE env vars in the Dockerfile. The Python catch-all now only serves the SPA shell (index.html) at / and for client-side routes. Every module logs through getLogger(__name__): lifecycle and business events at INFO, per-move and store detail at DEBUG. The built-in default writes DEBUG to the console; LOGGING_CONFIG points at a YAML file in the logging.config.dictConfig schema to take over the configuration. PyYAML becomes a direct dependency.
tavolo
A platform for multiplayer card games. The first game is scopone scientifico — the four-player, fixed-partnership Italian card game:
server/— backend: Python + kaya framework, OIDC login, live games in Redis, match statistics in Postgres. See server/README.md.web/— frontend: Rust + Sycamore compiled to WebAssembly, built with Trunk. Card images are the CC0 woodcut napoletane deck traced from a 1902 Naples print (SONDLecT/woodcut-napoletane).
Run the whole stack
docker compose up --build
Postgres, Redis, a mock OIDC provider (test users alice, bob, carol,
dave), the database migrator and the app all come up together. The app —
frontend and API — listens on http://127.0.0.1:8080.
Because both the browser and the app talk to the OIDC issuer at
http://mockoauth:8180/tavolo, add a host entry once:
echo "127.0.0.1 mockoauth" | sudo tee -a /etc/hosts
Between hands
When a hand ends but the match is not decided, the game pauses on a
scoring summary screen: every player sees how each category was won
(carte, denara, settebello, primiera, scope) with the running totals and
must click "Understood" before the next hand is dealt. If someone is away
the next hand is dealt automatically after HAND_ACK_TIMEOUT_SECONDS
(default 30s). The match-ending hand is explained on the final screen.
On your turn
Every turn shows a countdown (TURN_TIMEOUT_SECONDS, default 30s). If a
player does not move — disconnected or fallen asleep — the server plays a
random legal card for them (randomizing among the legal captures when the
rules require a capture), so one absent player cannot stall the table.
Development
Backend (from server/):
cd server
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
.venv/bin/pip install -e '.[dev]'
.venv/bin/python -m unittest discover -s tests -t .
.venv/bin/mypy src
Frontend (from web/), with the backend running on :8080:
cd web
trunk serve # SPA on http://localhost:8000, /api /auth /ws proxied
Trunk proxies /api, /auth and /ws to 127.0.0.1:8080 (see
web/Trunk.toml). For the login redirect to land back on the dev server,
run the backend with:
OIDC_POST_LOGIN_REDIRECT=http://localhost:8000/ \
OIDC_POST_LOGOUT_REDIRECT=http://localhost:8000/ \
.venv/bin/granian --host 127.0.0.1 --port 8080 tavolo.app:app
Card images are committed under web/assets/cards/; web/fetch-cards.sh
re-downloads them if needed.
