CDN: UNPKG | jsDelivr (available as window.ContentLoader)

Usage

<ContentLoader/>

<script>
import ContentLoader from 'svelte-content-loader';
</script>

Built-in loaders

import {
  FacebookLoader,
  CodeLoader,
  BulletListLoader,
  InstagramLoader,
  ListLoader
} from 'svelte-content-loader'

ContentLoader is a meta loader while other loaders are just higher-order components of it. By default ContentLoader only displays a simple rectangle, here's how you can use it to create custom loaders:

<ContentLoader>
  <rect x="0" y="0" rx="3" ry="3" width="250" height="10" />
  <rect x="20" y="20" rx="3" ry="3" width="220" height="10" />
  <rect x="20" y="40" rx="3" ry="3" width="170" height="10" />
  <rect x="0" y="60" rx="3" ry="3" width="250" height="10" />
  <rect x="20" y="80" rx="3" ry="3" width="200" height="10" />
  <rect x="20" y="100" rx="3" ry="3" width="80" height="10" />
</ContentLoader>

This is also how ListLoader is created.

If you are not using using es6, instead of importing add

<script src="/path/to/svelte-content-loader/index.js"></script>

just before closing body tag.
