Virtual Scroll Grid For Vue.js

A reusable virtual scroller for Vue 3 that supports big amount grid items with high scroll performance.

How to use it:

1. Import the component.

import Grid from "../Grid.vue";

2. Create a basic virtual scroll grid.

<Grid
  :length="length"
  :pageSize="pageSize"
  :pageProvider="pageProvider"
  :class="$style.grid"
>
  <template v-slot:probe>
    <ProductItem sizes="(min-width: 768px) 360px, 290px" />
  </template>
  <template v-slot:placeholder="{ style }">
    <ProductItem :style="style" sizes="(min-width: 768px) 360px, 290px" />
  </template>
  <template v-slot:default="{ item, style }">
    <ProductItem
      :handle="item.handle"
      :price="item.price * 100"
      :compare-at-price="item.compare_at_price * 100"
      :published-at="new Date(item.published_at)"
      :style="style"
      :master-src="item.product_image"
      :initial-alt-master-src="true"
      :alt="item.title"
      sizes="(min-width: 768px) 360px, 290px"
      :tags="item.tags"
      :vendor="item.vendor"
      :title="item.title"
    />
  </template>
</Grid>

3. All default props.

// The number of items in the list.
length: {
  type: Number as PropType<number>,
  required: true,
  validator: (value: number) => Number.isInteger(value) && value >= 0,
},
// The callback that returns a page of items as a promise.
pageProvider: {
  type: Function as PropType<PageProvider>,
  required: true,
},
// Debounce window in milliseconds on the calls to `pageProvider`,
// which is useful for avoiding network requests of skimmed pages.
pageProviderDebounceTime: {
  type: Number as PropType<number>,
  required: false,
  default: 0,
  validator: (value: number) => Number.isInteger(value) && value >= 0,
},
// The number of items in a page from the item provider (e.g. a backend API).
pageSize: {
  type: Number as PropType<number>,
  required: true,
  validator: (value: number) => Number.isInteger(value) && value >= 1,
},
// Scroll to a specific item by index, must be less than the length prop
scrollTo: {
  type: Number as PropType<number>,
  required: false,
  validator: (value: number) => Number.isInteger(value) && value >= 0,
},
// Snap to `scrollTo` when the grid container is resized
respectScrollToOnResize: {
  type: Boolean as PropType<boolean>,
  required: false,
  default: true,
},
scrollBehavior: {
  type: String as PropType<"smooth" | "auto">,
  required: false,
  default: "smooth",
  validator: (value: string) => ["smooth", "auto"].includes(value),
},
tag: {
  type: String as PropType<string>,
  required: false,
  default: "div",
},
probeTag: {
  type: String as PropType<string>,
  required: false,
  default: "div",
},
getKey: {
  type: Function as PropType<(internalItem: InternalItem) => number | string>,
  required: false,
  default: undefined,
},
