lkdoko is a simple server-/client-implementation of the popular (mainly in Germany) card game Doppelkopf.
The frontend is implemented in scala.js using Laminar (and laminext).
The backend's business logic is implemented as purely functional, immutable state machine and aims to be portable to different server libraries.
There currently are two server implementations: one using pekko-http, one using http4s.
During the spring 2020 C-19 lockdown, there was a sudden need for a solution to play this game remotely.
While there are a few commercial offerings, none of these offer the exact rules that I like to play - and none of them are free.
By now, it also serves as a personal playground for trying out new scala stuff.
The project still is a "minimal playable prototype".
The UI doesn't look pretty and there are various features that one could hope for that are not implemented (e.g.: configurable rules, supporting multiple games in parallel, ...).
Nevertheless, playing it in this state has already been fun for a few test users.
This project took inspiration from the following projects:
- jrudolph/pekko-http-scala-js-websocket-chat for the (intial) overall project structure
Svg playing cards were copied from vector-playing-cards.
