A backend for chess positions, games and collections. Please notice that by itself, this backend does nothing. You need a client to interact with this backend.
The easiest way is to just run docker-compose up.
Resker by default listens on port 8001, but you can change this by passing the envvar HTTP_PORT when running docker-compose: HTTP_PORT=8080 docker-compose up
Resker exposes an api, and to help towards security Resker requires an API Key to validate requests, every client connecting to Resker needs to send the header x-api-key, the default api-key is 894hmt3x489ht89p3x, but you can change this with the envvar X_API_KEY when doing docker-compose up
