React component that uses SVG to create a collection of loaders which simulates the structure of the content that will be loaded, similar to Facebook cards loaders.
- ⚙️ Completely customizable: you can change the colors, speed and sizes;
- ✏️ Create your own loading: use the create-content-loader to create your own custom loadings easily;
- 👌 You can use right now: there are a lot of presets to use it, see the examples;
- 🚀 Performance: it uses pure SVG to work, so it works without any extra scripts, canvas, etc;
Yarn: $ yarn add react-content-loader
Npm: $ npm i react-content-loader --save
You can use it in two ways (See the options):
// import the component
import ContentLoader, { Facebook } from 'react-content-loader'
const MyLoader = () => <ContentLoader />
const MyFacebookLoader = () => <Facebook />
Or in custom mode, using the online tool
const MyLoader = () => (
<ContentLoader>
{/* Pure SVG */}
<rect x="0" y="0" rx="5" ry="5" width="70" height="70" />
<rect x="80" y="17" rx="4" ry="4" width="300" height="13" />
<rect x="80" y="40" rx="3" ry="3" width="250" height="10" />
</ContentLoader>
)

Safari / iOS
When using
rgba
as aprimaryColor
orsecondaryColor
value, Safari does not respect the alpha channel, meaning that the color will be opaque. To prevent this, instead of using anrgba
value forprimaryColor
/secondaryColor
, use thergb
equivalent and move the alpha channel value to theprimaryOpacity
/secondaryOpacity
props.{/* Opaque color in Safari and iOS */} <ContentLoader primaryColor="rgba(0,0,0,0.06)" secondaryColor="rgba(0,0,0,0.12)"> {/* Semi-transparent color in Safari and iOS */} <ContentLoader primaryColor="rgb(0,0,0)" secondaryColor="rgb(0,0,0)" primaryOpacity={0.06} secondaryOpacity={0.12}>
