Carousel

About

The carousel component is built using the Embla Carousel library.

Installation

npx nyxb@latest add carousel

Usage

import {
  Carousel,
  CarouselContent,
  CarouselItem,
  CarouselNext,
  CarouselPrevious,
} from "~/components/ui/carousel"

<Carousel>
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
  </CarouselContent>
  <CarouselPrevious />
  <CarouselNext />
</Carousel>

Examples

Sizes

To set the size of the items, you can use the basis utility class on the <CarouselItem />.

Example

// 33% of the carousel width.
<Carousel>
  <CarouselContent>
    <CarouselItem className="basis-1/3">...</CarouselItem>
    <CarouselItem className="basis-1/3">...</CarouselItem>
    <CarouselItem className="basis-1/3">...</CarouselItem>
  </CarouselContent>
</Carousel>

Responsive

// 50% on small screens and 33% on larger screens.
<Carousel>
  <CarouselContent>
    <CarouselItem className="md:basis-1/2 lg:basis-1/3">...</CarouselItem>
    <CarouselItem className="md:basis-1/2 lg:basis-1/3">...</CarouselItem>
    <CarouselItem className="md:basis-1/2 lg:basis-1/3">...</CarouselItem>
  </CarouselContent>
</Carousel>

Spacing

To set the spacing between the items, we use a pl-[VALUE] utility on the <CarouselItem /> and a negative -ml-[VALUE] on the <CarouselContent />.

Why: I tried to use the gap property or a grid layout on the <CarouselContent /> but it required a lot of math and mental effort to get the spacing right. I found pl-[VALUE] and -ml-[VALUE] utilities much easier to use.

You can always adjust this in your own project if you need to.

Example

<Carousel>
  <CarouselContent className="-ml-4">
    <CarouselItem className="pl-4">...</CarouselItem>
    <CarouselItem className="pl-4">...</CarouselItem>
    <CarouselItem className="pl-4">...</CarouselItem>
  </CarouselContent>
</Carousel>

Responsive

<Carousel>
  <CarouselContent className="-ml-2 md:-ml-4">
    <CarouselItem className="pl-2 md:pl-4">...</CarouselItem>
    <CarouselItem className="pl-2 md:pl-4">...</CarouselItem>
    <CarouselItem className="pl-2 md:pl-4">...</CarouselItem>
  </CarouselContent>
</Carousel>

Orientation

Use the orientation prop to set the orientation of the carousel.

<Carousel orientation="vertical | horizontal">
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
  </CarouselContent>
</Carousel>

Dots

Enhance carousel navigation with the CarouselDots component, which presents interactive indicators for each slide.

Usage

Embed within the Carousel, connecting automatically to its context for slide information and active index.

dotsPosition: Dots placement - "top", "bottom", "left", or "right".
size: Size of Dot - "default", "sm", "md", "lg".
gap: Space between dots - "default", "sm", "md", "lg".

<Carousel
  orientation="vertical | horizontal"
  dotsPosition="top | bottom | left | right"
>
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    ...
  </CarouselContent>
  <CarouselDots size="sm | md | lg" gap="sm | md | lg" />
  ...
</Carousel>

Options

You can pass options to the carousel using the opts prop. See the Embla Carousel docs for more information.

<Carousel
  opts={{
    align: "start",
    loop: true,
  }}
>
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
  </CarouselContent>
</Carousel>

API

Use a state and the setApi props to get an instance of the carousel API.

Slide 0 of0

import { type CarouselApi } from "~/components/ui/carousel"
 
export function Example() {
  const [api, setApi] = React.useState<CarouselApi>()
  const [current, setCurrent] = React.useState(0)
  const [count, setCount] = React.useState(0)
 
  React.useEffect(() => {
    if (!api) {
      return
    }
 
    setCount(api.scrollSnapList().length)
    setCurrent(api.selectedScrollSnap() + 1)
 
    api.on("select", () => {
      setCurrent(api.selectedScrollSnap() + 1)
    })
  }, [api])
 
  return (
    <Carousel setApi={setApi}>
      <CarouselContent>
        <CarouselItem>...</CarouselItem>
        <CarouselItem>...</CarouselItem>
        <CarouselItem>...</CarouselItem>
      </CarouselContent>
    </Carousel>
  )
}

Events

You can listen to events using the api instance from setApi.

import { type CarouselApi } from "~/components/ui/carousel"
 
export function Example() {
  const [api, setApi] = React.useState<CarouselApi>()
 
  React.useEffect(() => {
    if (!api) {
      return
    }
 
    api.on("select", () => {
      // Do something on select.
    })
  }, [api])
 
  return (
    <Carousel setApi={setApi}>
      <CarouselContent>
        <CarouselItem>...</CarouselItem>
        <CarouselItem>...</CarouselItem>
        <CarouselItem>...</CarouselItem>
      </CarouselContent>
    </Carousel>
  )
}

See the Embla Carousel docs for more information on using events.

Plugins

You can use the plugins prop to add plugins to the carousel.

import Autoplay from "embla-carousel-autoplay"
 
export function Example() {
  return (
    <Carousel
      plugins={[
        Autoplay({
          delay: 2000,
        }),
      ]}
    >
      // ...
    </Carousel>
  )
}

See the Embla Carousel docs for more information on using plugins.
