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 { DatePicker } from '@app/components/ui/date-picker.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><DatePicker label="Delivery date" defaultMonth="2026-11-01" /></div><p role="status">{notice}</p></>);
}

Contract and compatibility

Accessibility pattern: WAI-ARIA guidance

Calendar embedded in package-owned native modal Dialog; uses existing focus, Escape and return behavior.
Browser-forced dismissal can supersede a rejected close request; applications should normally accept native close requests.
ISO value collection and open state can each be controlled. A named hidden input submits dates joined by /. Open data-state is derived; hydrate in an island.

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