SortableJS-vue3

Demo | npm

This is a thin wrapper around the great SortableJS library. I had many issues migrating from Vue.Draggable to vue.draggable.next, and after briefly investigating I decided that it was too complicated and a smaller solution was the answer. This wrapper attempts to keep you as close to Sortable as possible.

Why not use <other library>?

• Vue.Draggable only supports Vue 2
• vue.draggable.next uses the Options API, has multiple open (and afaict useful) pull requests, and had weird bugs/side-effects when I tried and used it
• shopify/draggable and vue-shopify-dragable seemed promising but they don't supported nested components

Usage

You can see a demo with more complete code at https://sortablejs-vue3.maxleiter.com.

1. Install the package:

yarn add sortablejs-vue3 sortablejs

or

npm install sortablejs-vue3 sortablejs

2. Import the component in your <script setup> (or <script>):

import { Sortable } from "sortablejs-vue3";

3. Use the component:

<template>
  <main>
    <Sortable
      :list="elements"
      item-key="id"
      tag="div"
      :options="options"
    >
      <-- The Header and Footer templates below are optional -->
      <template #header>
          <header>
            <h1>SortableJS Vue3 Demo</h1>
          </header>
      </template>
      <template #item="{element, index}">
        <div class="draggable" :key="element.id">
          {{ element.name }}
        </div>
      </template>
      <template #footer>
          <footer class="draggable">A footer</footer>
      </template>
    </Sortable>
</template>

4. The list and item-key props are necessary. The options prop is an object that can contain any SortableJS option. You can find a full list of them here: https://github.com/SortableJS/Sortable#options
   • The tag prop is optional and defaults to div. It's the HTML node type for the outer element of the included template/slot.

Props

• list (Array<any>, required): your data to list
• itemKey (string | (item) => (string | number | Symbol), required): The name of the key present in each item in the list that corresponds to a unique value (to use as the key)
• tag (string, optional, default = "div"): The element type to render as
• options (Object, false): the SortableJS options minus event handlers (see below)

Events

You can listen to Sortable events by adding the listeners to the Sortable component. For example:

<Sortable
  :list="elements"
  item-key="id"
  @change="(event: Sortable.SortableEvent) => void"
  @choose="(event: Sortable.SortableEvent) => void"
  @unchoose="(event: Sortable.SortableEvent) => void"
  @start="(event: Sortable.SortableEvent) => void"
  @end="(event: Sortable.SortableEvent) => void"
  @add="(event: Sortable.SortableEvent) => void"
  @update="(event: Sortable.SortableEvent) => void"
  @sort="(event: Sortable.SortableEvent) => void"
  @remove="(event: Sortable.SortableEvent) => void"
  @filter="(event: Sortable.SortableEvent) => void"
  @move="(event: Sortable.MoveEvent, event2: Event) => void"
  @move.capture="(event: Sortable.MoveEvent, event2: Event) => boolean | -1 | 1"
  @clone="(event: Sortable.SortableEvent) => void"
>

Using plugins

You need to mount any plugins you want outside of the default before importing this library. For example, the below is correct:

import SortableJs from 'sortablejs';
import { Swap } from 'sortablejs/modular/sortable.core.esm';
SortableJs.mount(new Swap());

import { Sortable } from "sortablejs-vue3";

Use with a store

No changes are necessary to work with Vuex or another store. Just pass store.state.items as your list. To modify your data you need to manually listen to the events and calculate the new position with event.oldIndex and event.newIndex with something like the following:

const moveItemInArray = <T>(array: T[], from: number, to: number) => {
  const item = array.splice(from, 1)[0];
  array.splice(to, 0, item);
};

onEnd(event) { moveItemInArray(store.state.items, event.oldIndex, event.newIndex) }
