Svelte custom event on svelte typescript

I'm using clickOutside directive on my svelte-typescript project and I'm getting this error when I assign custom event to the related element

Type '{ class: string; onclick_outside: () => boolean; }' is not assignable to type 'HTMLProps<HTMLDivElement>'.
  Property 'onclick_outside' does not exist on type 'HTMLProps<HTMLDivElement>'

here's a snippet of my code

{#if profileToolbar}
<div
    transition:fly={{ y: -20, duration: 300 }}
    use:clickOutside={profileToolbarContainer}
    on:click_outside={() => (profileToolbar = !profileToolbar)}
    class="origin-top-right absolute right-0 mt-2 w-48 rounded-md
    shadow-lg z-10 shadow-md">

this is the clickOutside directive that I'm using currently https://svelte.dev/repl/0ace7a508bd843b798ae599940a91783?version=3.16.7

I'm new to typescript so I don't really know where to start with my google search, anyone knows how to tackle this issue? thanks for your help

Solution

  • Ok, so existing answers did work only partly for me. Given that the clickOutside action fires a custom event named click_outside i arrive at following solution:

    declare namespace svelte.JSX {
    interface HTMLProps<T> {
        onclick_outside?: (e: CustomEvent) => void;
    }
}
