To implement your chess bot you only need to create one class that implements the method:

  getNextMove(moves) {
      return uciMove;
  }

Where moves is a list of moves so far in uci format e.g. ["e2e4", "b8c6", "f2f4"]

See RandomPlayer for minimal implementation using chess.js

Hosting

If you register a free heroku account you can host a BOT like this one as is - just add your API_TOKEN to the environment property configuration. This code auto deploys and is live at https://test-o-a.herokuapp.com/

Hostless

You do not need to own a server to host a BOT, this code also runs in a browser. Watch how a BOT communicates with the server https://tailuge.github.io/bot-o-tron/dist/testBot.html
