React Native Skeleton Content

React native Skeleton Content, a simple yet fully customizable component made to achieve loading animation in a Skeleton-style. Works in both iOS and Android.

main

Installation

npm install react-native-skeleton-content

Usage

  1. Import react-native-skeleton-content:
import SkeletonContent from "react-native-skeleton-content";
  1. Once you create the SkeletonContent, you have two options:
  • Child Layout : The component will figure out the layout of its bones with the dimensions of its direct children (make sure to wrap them in sized-views, with width and height properties, otherwise, shiver animation might not work).
  • Custom Layout : You provide a prop layout to the component specifying the size of the bones (see the Examples section below). Herunder is the example with a custom layout.
render () {
return (
<SkeletonContent
    containerStyle={{flex: 1, width: 300}}
    isLoading={false}
    layout={[
    { width: 220, height: 20, marginBottom: 6 },
    { width: 180, height: 20, marginBottom: 6 },
    ]}
    >

    <Text style={styles.normalText}>
        Your content
    </Text>

    <Text style={styles.bigText}>
        Other content
    </Text>

</SkeletonContent>
)
}
  1. Then simply sync the prop isLoading to your state to show/hide the SkeletonContent when the assets/data are available to the user.
render () {
    const { isLoading } = this.state;
    return (
    <SkeletonContent
        containerStyle={{flex: 1, width: 300}}
        isLoading={isLoading}>
        ...
    />
)
}

Props

Name Type Default Description
isLoading bool required Shows the Skeleton bones when true
layout array of objects [] A custom layout for the Skeleton bones
duration number 1200 ms Duration of one cycle of animation
containerStyle object flex: 1 The style applied to the View containing the bones
easing Easing bezier(0.5, 0, 0.25, 1) Easing of the bones animation
animationType string "shiver" The animation to be used for animating the bones (see demos below)
animationDirection string "horizontalRight" Used only for shiver animation, describes the direction and end-point (ex: horizontalRight goes on the x-axis from left to right)
boneColor string "#E1E9EE" Color of the bones
highlightColor string "#F2F8FC" Color of the highlight of the bones

Examples

See the playground section to experiment :
1 - Changing the direction of the animation (animationDirection prop) :

direction_change

render () {
    return (
    <SkeletonContent
        containerStyle={{flex: 1, width: 300}}
        animationDirection="horizontalLeft"
        isLoading={true}>
        ...
    />
    )
}

2 - Changing the colors and switching to "pulse" animation (boneColor, highlightColor and animationType prop) :

color_change

render () {
    return (
    <SkeletonContent
        containerStyle={{flex: 1, width: 300}}
        boneColor="#121212"
        highlightColor="#333333"
        animationType="pulse"
        isLoading={true}>
        ...
    />
    )
}

3 - Customizing the layout of the bones (layout prop) :

layout_change

render () {
    return (
    <SkeletonContent
        containerStyle={{flex: 1, width: 300}}
        animationDirection="horizontalLeft"
        layout={[
        // long line
        { width: 220, height: 20, marginBottom: 6 },
        // short line
        { width: 180, height: 20, marginBottom: 6 },
        ...
        ]}
        isLoading={true}>
        ...
    />
    )
}
