contro-ui

This UI library is used by Nostlan to create a UI that can be interacted with via game controllers and/or mouse and keyboard. It requires jQuery and Mousetrap. Optionally you can install gca-js as a peer dependency for Gamecube controller support.

global.cui = require("contro-ui");
cui.start();
