Svelte Use

onClickOutside

List for clicks outside of an element. Useful for modal or dropdown.

Usage 

<script>
  import { writable, onClickOutside } from '@svelte-use/core'

  const target = writable()

  onClickOutside(target, (event) => {
    // do something
  })
</script>

<div bind:this={$target}>Hello World</div>
<div>Outside element</div>

This function uses Event.composedPath() which is NOT supported by IE 11, Edge 18 and below. If you are targeting these browsers, we recommend you to include this code snippet on your project.
