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 { Carousel } from '@app/components/ui/carousel.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><Carousel label="Order attachments" slides={[{label:"Invoice",content:<p>Invoice</p>},{label:"Packing slip",content:<p>Packing slip</p>}]} /></div><p role="status">{notice}</p></>);
}

Props

Generated from native deno doc --json --private over the shipped implementation. Compound component props retain their owning interface; native attributes pass through where declared.

`CarouselProps`	`label`	`string`	No
`CarouselProps`	`slides`	`[object Object]`	No
`CarouselProps`	`orientation`	`"horizontal" \| "vertical"`	Yes

`CarouselProps`	`dots`	`boolean`	Yes
`CarouselProps`	`counter`	`boolean`	Yes
`CarouselProps`	`defaultIndex`	`number`	Yes
`CarouselProps`	`onIndexChange`	`(index: number) => void`	Yes

Contract and compatibility

Accessibility pattern: WAI-ARIA guidance

Native overflow scrolling and mandatory snap points retain touch/trackpad behavior. ResizeObserver realigns the current slide without global listeners.
No autoplay. Boundary controls use guarded aria-disabled so activation never removes focus. After hydration only the current slide is interactive; before hydration native scrolling keeps all slide content available.
defaultIndex is clamped to available slides; changing slide count or orientation keeps a valid current index.

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