Animated loading skeletons that automatically adapt to your app

Create skeleton screens that automatically adapt to your app!

Make beautiful, animated loading skeletons that automatically adapt to your app.

Basic usage

Install by npm/yarn with react-loading-skeleton.

import Skeleton from 'react-loading-skeleton';

<Skeleton/> // Simple, single-line loading skeleton
<Skeleton count={5}/> // Five-line loading skeleton

Principles

Adapts to the styles you have defined

The <Skeleton> component is designed to be used directly in your components,
in place of content while it's still loading.
Unlike other libraries, rather than meticulously crafting a skeleton screen to
match the font-size, line-height or margins your content takes on,
use a <Skeleton> component to have it automatically fill the correct dimensions.

For example:

class Blogpost extends Component {
  render() {
    return (
      <div style={{ fontSize: 20, lineHeight: 2 }}>
        <h1>{this.props.title || <Skeleton />}</h1>
        {this.props.body || <Skeleton count={10} />}
      </div>
    );
  }
}

...will produce the correctly-sized skeletons for the heading and body sections
without any further configuration of the <Skeleton> component.

This ensures the loading state remains up-to-date with any changes
to your layout or typography.

Don't make dedicated skeleton screens

Instead, make components with built-in skeleton states.

In addition to keeping the styling in-sync, here are some other reasons to do this:

  1. Components represent all possible states it can be in - loading included.
  2. It allows for more flexible loading patterns - in the Blogpost example, it's possible to have the title load first, and then the body, while having both pieces of content show loading skeletons at the right time.

Theming

Using a <SkeletonTheme> component, you can easily change the colors of all
skeleton components below it in the React hierarchy:

import Skeleton, { SkeletonTheme } from "react-loading-skeleton";

<SkeletonTheme color="#202020" highlightColor="#444">
  <p>
    <Skeleton count={3} />
  </p>
</SkeletonTheme>;

Duration

<Skeleton duration={2} />

duration: Number, defaults to 1.2

Duration is how long it takes do one cycle of the skeleton animation.

Width

width: Number | String | null, defaults to null

<Skeleton width={100} />

Width of the skeleton. Useful when the skeleton is inside an inline element with
no width of its own.
