Easy Vue Virtual Scroll List Component

Install & Download:

npm install vue-virtual-scroll-list --save

Description:

A Vue component supports big data by using virtual scroll list. Tiny, smooth, and without any dependence.

How to use it:

1. Import and register the component.

import VirtualList from 'vue-virtual-scroll-list'

export default {
  components: { 'virtual-list': VirtualList }
}

2. Add the virtual-list component to the template.

<template>
  <div>
    <virtual-list style="height: 400px; overflow-y: auto;"
      :data-key="'uid'"
      :data-sources="items"
      :data-component="itemComponent"
    />
  </div>
</template>

3. Define your list items.

<template>
  <div>{{ index }} - {{ source.text }}</div>
</template>
<script>
  export default {
    name: 'item-component',
    props: {
      index: { // number index
        type: Number
      },
      source: { // {uid: 'unique_1', text: 'abc'}
        type: Object,
        default () {
          return {}
        }
      }
    }
  }
</script>

// root component
import Item from './Item'
import VirtualList from 'vue-virtual-scroll-list'
export default {
  name: 'root',
  data () {
    return {
      itemComponent: Item,
      items: [{uid: 'unique_1', text: 'abc'}, {uid: 'unique_2', text: 'xyz'}, ...]
    }
  },
  components: { 'virtual-list': VirtualList }
}
