Svelte Carousel

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;
	}

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 greater 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.

// will show 1 slide below 500px width, 2 at 500, 3 at 800.
