Usage and examples

The preview runs this JSX with the installed components. Import any composed primitives from your UI directory.

TypeScript

import { useState } from 'preact/hooks';
import { Button } from '@app/components/ui/button.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><div class="demo-row"><Button onClick={() => report("Changes saved")}>Save changes</Button><Button variant="outline">Cancel</Button><Button disabled>Disabled</Button></div></div><p role="status">{notice}</p></>);
}

Contract and compatibility

Accessibility pattern: WAI-ARIA guidance

Native DOM attributes pass through where the implementation accepts them.

Design contract values marked planned are not implementation props. The props above describe what ships today.
