SvelteKit support

There are several things to keep in mind when svelte-carousel is used with SvelteKit. This is because svelte-carousel is a client-side library and depends on document and window. See more in SvelteKit FAQ.

  1. Install svelte-carousel as a dev dependency. Why as a dev dependency?
yarn add svelte-carousel -D
npm install svelte-carousel -D
  1. Extend kit in svelte.config.js to include the vite property
const config = {
  // existing props
  kit: {
    // existing props
    vite: {
      optimizeDeps: {
        include: ['lodash.get', 'lodash.isequal', 'lodash.clonedeep']
      }
      // plugins: []
    }
  }
}
  1. Import and use it:
<script>
  import Carousel from 'svelte-carousel';
  import { browser } from '$app/environment';

  let carousel; // for calling methods of the carousel instance
  
  const handleNextClick = () => {
    carousel.goToNext()
  }
</script>

{#if browser}
  <Carousel
    bind:this={carousel}
  >
    <div>1</div>
    <div>2</div>
    <div>3</div>
  </Carousel>
{/if}

<button on:click={handleNextClick}>Next</button>

Vite support

  1. Extend optimizeDeps.include in vite.config.js
export default defineConfig({
  optimizeDeps: {
    include: ['lodash.get', 'lodash.isequal', 'lodash.clonedeep']
  }
})
  1. Import and use it:
<script>
  import Carousel from 'svelte-carousel'

  let carousel; // for calling methods of the carousel instance
  const handleNextClick = () => {
    carousel.goToNext()
  }
</script>

<Carousel
