The backend README, how to run and test it, what is easy to get wrong
with the game loop and the shared data formats, and the deployment note.
The web app was played against it in Chrome: a full game with a
spectator, a reload, a restart mid-game, the replay and a game lost on
time.
- postgres replaces keycloak-db and holds a keycloak and a mancala database,
each with its own user, created by apps/postgres/init
- valkey with an append-only file for live game state and caches
- backend gets DATABASE_URL and VALKEY_URL
- Apps and @mancala/core depend on the packages in this repo through
link: dependencies instead of the npm releases, so changes no longer
need a publish
- Root package.json gets a build:packages script that installs and
builds both packages
- Backend and frontend Docker images are built from the repo root so
they can include the packages; compose builds them that way
- Metro watches the packages folder and resolves their imports from the
app's node_modules
