The container ran as the unprivileged "node" user, but bind-mounted host
directories (e.g. ./data:/app/data in docker-compose or an Unraid appdata
folder) are mounted with root ownership. The node user therefore could not
create trxtd.db in /app/data, failing at startup with:
Error: unable to open database file
at file:///app/server/db.mjs:12
Fix:
- Add docker-entrypoint.sh that mkdir/chown /app/data to node:node on
container start, then drops privileges back to node via su-exec
- Install su-exec in the runtime stage (apk add --no-cache su-exec)
- Remove USER node so the entrypoint runs as root and can fix ownership,
with privilege dropping handled inside the entrypoint instead
- Wire the script up as ENTRYPOINT, keeping CMD as the app itself
The mount path itself is unchanged (/app/data, host ./data). Verified with
a real bind mount: /health responds ok and trxtd.db/-shm/-wal are created
in the mounted directory.
- Add a toggle on the picture-in-picture window to swap the big board
with the mini view of the opponent's field
- Color-coded frame and badge identify whose board is currently shown
(blue = player 1, orange = player 2)
- Block building and rushing while spectating the opponent's board;
the PiP then shows your own field instead
- Clarify duel-mode descriptions in lobby and start screen, add hints
in the multiplayer bar
- Replace previous announcement banners so only one shows at a time
- Add CSP, frame and referrer headers for served static files
- Enforce WebSocket origin check to prevent cross-site hijacking
- Trust X-Forwarded-For only when the peer is from a private proxy network
- Limit concurrent connections (500 total / 20 per IP) and rooms (300)
- Add ALLOWED_ORIGINS env var for additional WebSocket origins
- Document reverse proxy setup (NPM/NPMplus) in README
- Add scripts/security-test.mjs to verify origin and limit behavior
- Add Dockerfile (multi-stage build, unprivileged user, healthcheck),
docker-compose.yml and .dockerignore
- Server now serves static dist/ frontend and WebSocket relay on a
single port (PORT, default 3001) with path-traversal protection,
immutable asset caching and SPA fallback
- Client connects via same origin in production; dedicated ws port is
only used for vite dev/preview
- Document Docker usage, env vars and manual production mode in README
