Svelte Dnd List
A very lightweight, dependency free and simple drag and drop library for Svelte. The library supports multiple types of lists, and moving items between lists.
It's still currently in development and as such its API is not stable and might change as development continues.
Getting Started
Install through npm with:
npm i svelte-dnd-list
Below is a very simple example that shows reordering an array of numbers in a vertical list. You can play with this example here.
<svelte:options immutable={true} />
<script lang="ts">
import DragDropList, { VerticalDropZone, reorder, type DropEvent } from 'svelte-dnd-list';
let items = [1, 2, 3, 4, 5];
function onDrop({ detail: { from, to } }: CustomEvent<DropEvent>) {
if (!to || from === to) {
return;
}
items = reorder(items, from.index, to.index);
}
</script>
