@svuick/virtual-list
A virtual list component for Svelte apps. Instead of rendering all your data, <VirtualList> just renders the bits that are visible, keeping your page nice and light.
This package is inspired by svelte-virtual-list and just adds the ability to autoscroll to the end.
Installation
npm i @svuick/virtual-listExample
Instead of rendering all your data, <VirtualList> just renders the bits that are
visible, keeping your page nice and light.

Usage
<script>
import VirtualList from '@sveltejs/svelte-virtual-list';
const things = [
// these can be any values you like
{ name: 'one', number: 1 },
{ name: 'two', number: 2 },
{ name: 'three', number: 3 },
// ...
{ name: 'six thousand and ninety-two', number: 6092 }
];
</>
<VirtualList items={things} let:item>
<!-- this will be rendered for each currently visible item -->
<p>{item.number}: {item.name}</p>
</VirtualList>start end end
You can track which rows are visible at any given by binding to the start and end values:
<VirtualList items={things} bind:start bind:end>
<p>{item.number}: {item.name}</p>
</VirtualList>
<p>showing {start}-{end} of {things.length} rows</p>You can rename them with e.g. bind:start={a} bind:end={b}.
height
By default, the <VirtualList> component will fill the vertical space of its container. You can specify a different height by passing any CSS length:
<VirtualList height="500px" items={things} let:item>
<p>{item.number}: {item.name}</p>
</VirtualList>itemHeight
You can optimize initial display and scrolling when the height of items is known in advance. This should be a number representing a pixel value.
<VirtualList itemHeight={48} items={things} let:item>
<p>{item.number}: {item.name}</p>
</VirtualList>
