GET /games/popular?kind=finished returns the most watched finished
games even when games are being played, so the web app can show live
and popular games together.
- Banner for the user's game in progress with a Continue button
- Live games as cards with the real board, updated over WebSocket; the
most watched finished games when nothing is live
- The user's last 3 games, from their side of the board, with the result
as they would say it
- The lobby offers to continue the game in progress when a new one is
refused
- Spectators register once connected and identified, and again after a
reconnect, so they are counted
- The backend includes games that ended but are not saved yet in /game/:id
and the lists
- GET /games/me/active and /games/me (Bearer token), /games/popular (live
games, or the most spectated finished ones), and /game/:id now also
returns saved records of finished games
- Lists are cached in Valkey for 10 seconds, cleared when a game is saved,
and empty instead of failing while the database is down
- Live game previews over WebSocket: subscribers get the top 5 on
subscribe and on change, at most once per second, without counting as
spectators; ids are public ids
- RTMT supports several connection listeners
