This project is now archived. We don't use carousels any more, and you shouldn't either.

js-standard-style CircleCI svelte-v2 svelte-v3

Svelte Carousel / Slider

This is a ground-up rewrite of the original Svelte Carousel/Slider using Svelte v3, and Siema, the goal being a fully working carousel with a tiny size.

Usage

This library is pure javascript, so can be used with any framework you like.

Demo

The simplest possible demo

npm install
npm run dev # http://localhost:12001

To use within a Svelte application:

npm i -D @beyonk/svelte-carousel

Usage

<Carousel>
  <div class="slide-content">Slide 1</div>
  <div class="slide-content">Slide 2</div>
  <div class="slide-content">Slide 3</div>
  <div class="slide-content">Slide 4</div>
</Carousel>

<script>
    import Carousel from '@beyonk/svelte-carousel'
    import { ChevronLeftIcon, ChevronRightIcon } from 'svelte-feather-icons'
</script>

Options

Controls

You can set the controls to be anything you like, though the default height and width are set to 40px. Just use the slots available to insert your own content.

npm i -D svelte-feather-icons
<Carousel>
  <span class="control" slot="left-control">
    <ChevronLeftIcon />
  </span>
  <div class="slide-content">Slide 1</div>
  ...
  <div class="slide-content">Slide n</div>
  <span class="control" slot="right-control">
    <ChevronRightIcon />
  </span>
</Carousel>

<script>
    import Carousel from './Carousel.svelte'
    import { ChevronLeftIcon, ChevronRightIcon } from 'svelte-feather-icons'
</script>

If you need to override height and width, you can use CSS:

    .control :global(svg) {
        width: 100%;
        height: 100%;
        color: #fff;
        border: 2px solid #fff;
        border-radius: 32px;
    }

Attributes

You can pass the following attributes:

Attribute Type Default Value Description
loop boolean true At the end of the carousel, loop through to the first slide again, seamlessly
perPage integer 3 Number of slides on a single page. Note that this needs to be less than or equal to the number of slides in your carousel
autoplay integer 0 Auto-change slide at an interval (in milliseconds). 0 means don't autoplay.
duration number 200 Slide transition duration in milliseconds.
easing string 'ease-out' It is like a CSS transition-timing-function — describes acceleration curve.

dots boolean true Toggles visibility of slider dots.

<Carousel perPage={{ 800: 3, 500: 2 }}>
// will show 1 slide below 500px width, 2 at 500, 3 at 800.

Events

The Carousel components emits the following events:

Name Data Description
change { currentSlide, slideCount } currentSlide: The current slide index. Can be a positive or negative integer. slideCount: The number of slides.

Actions

<Carousel bind:this={carousel} on:mouseenter={enter} on:mouseleave={leave}>
  <div class="slide-content">Slide 1</div>
  ...
  <div class="slide-content">Slide n</div>
</Carousel>

<script>
  import Carousel from './Carousel.svelte'
  let carousel;

  function enter() {
    carousel.pause();
  }

  function leave() {
    carousel.resume();

</script>
