      fs.writeFileSync('./src/box.generated.d.ts', result.boxDts);
    },
  }
}

2. Add this plugin to your build tool

Vitejs

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [..., themePlugin()],
})

3. Include box-theme.generated.css in your root file

import './box-theme.generated.css';

In the project root file (main.tsx) use Theme.setup

import Theme from '@cronocode/react-box/theme';

Theme.setup({
  button: {
    styles: {
      px: 4
    },
    themes: {
      mytheme: {
        px: 8
      }
    }
  },
  ...
})

All styles will be applied to Button component

import Button from '@cronocode/react-box/components/button';

function MyComponent() {
  return <Button>Click me</Button>
}

or is possible to use Button with specific theme

import Button from '@cronocode/react-box/components/button';

function MyComponent() {
  return <Button theme="mytheme">Click me</Button>
}

In CSS file is possible to override default values for:

  --borderColor: black;
  --outlineColor: black;
  --lineHeight: 1.2;
  --fontSize: 14px;
  --transitionTime: 0.25s;
