The HookUI-Framework is reusable React code and CSS styles you can use to save a bit of time, if you want your UI to look like the built-in Game UI.

First install the project with npm, make sure you have a package.json before installing dependencies (or run npm init once first). Then run:
npm install captain-of-coit/hookui-frameworkThen you can access the built-in components with their styling by importing the right component:
