What is @tanstack/vue-virtual?
@tanstack/vue-virtual is a Vue.js package that provides utilities for efficiently rendering large lists and grids by virtualizing the DOM. This means it only renders the visible items in the viewport, which can significantly improve performance for applications dealing with large datasets.
What are @tanstack/vue-virtual's main functionalities?
Virtualized List
This feature allows you to create a virtualized list where only the items visible in the viewport are rendered. This can greatly improve performance when dealing with large lists.
<template>
<VirtualList :items="items" :itemSize="50">
<template #default="{ item, index }">
<div :key="index" class="item">
{{ item }}
</div>
</template>
</VirtualList>
</template>
<script>
import { VirtualList } from '@tanstack/vue-virtual';
export default {
components: { VirtualList },
data() {
return {
items: Array.from({ length: 10000 }, (_, i) => `Item ${i}`)
};
}
};
</script>
Virtualized Grid
This feature allows you to create a virtualized grid where only the cells visible in the viewport are rendered. This is useful for applications that need to display large grids of data.
<template>
<VirtualGrid :items="items" :columnCount="3" :rowHeight="100" :columnWidth="100">
<template #default="{ item, rowIndex, columnIndex }">
<div :key="`${rowIndex}-${columnIndex}`" class="grid-item">
{{ item }}
</div>
</template>
</VirtualGrid>
</template>
<script>
import { VirtualGrid } from '@tanstack/vue-virtual';
export default {
components: { VirtualGrid },
data() {
return {
items: Array.from({ length: 10000 }, (_, i) => `Item ${i}`)
};
}
};
</script>
