My implementation of the board game Splendor using boardgame.io and React. You can play Gembalaya as well as some other games at https://lhog.herokuapp.com/.
Run npm install to install the necessary packages. Run the server using npm run dev-server and the client using npm run dev. This will instantiate two game boards in a single window for easy testing.
Alternatively, you can run npm run dev-lobby (with the server running) to use the basic lobby provided by boardgame.io.
This is currently setup for deployment to Heroku with the server and client running at a single port. Run npm start to deploy.
However, this deployment only has a simple lobby implementation and no persistence. Check out Lewis' House of Games for a more robust lobby implementation meant to host many boardgame.io games.
To publish the package to npm, run npm run publish:npm to compile files for publication, followed by npm publish.
