react-load-image

This is a fork of https://github.com/hzdg/react-imageloader, however many design changes were made and deprecations fixed so it warranted its own repo/package.

This React component allows you to display content while waiting for the image to load, as well as by showing alternate content if the image fails to load.

Installing

npm i react-load-image

Usage

importReactfrom'react';importImageLoaderfrom'react-load-image';functionPreloader(props){return<imgsrc="spinner.gif"/>;}React.render((<ImageLoadersrc="/path/to/image.jpg"><img/><div>Error!</div><Preloader/></ImageLoader>),document.body);

Props

Name	Type	Description
onError	function	An optional handler for the [error] event.
onLoad	function	An optional handler for the [load] event.
src	string	The URL of the image to be loaded, will be passed as the src prop to your first child provided. If you want to use it as a background image, make your first child a react component like Name = (props) => <div style={{backgroundImage: props.src}}/> and do
srcSet	string	An optional value for the srcset attribute of the img

Children

The first child of ImageLoader will be rendered when the image is successfully loaded. The src prop will be passed to it.

The second child of ImageLoader will be rendered when the image load fails.

The third child of ImageLoader will be rendered when the image is in the process of loading

Avoiding duplication Example

importReactfrom'react';importImageLoaderfrom'react-load-image';importImageErrorfrom'./ImageError';importImageLoadingfrom'./ImageLoading';constImage=(props)=><ImageLoader{...props}>{this.props.children[0]}<ImageError/><ImageLoader/></ImageLoader>exportdefaultImage;

---

importImagefrom'./Image';
...
<Imagestyle={{width: '50px'}}><imgstyle={{border: none}}/></Image>...

Using it as a backgroundImage

importReactfrom'react';constBackgroundImage=({src, style ={}, ...props}={})=><divstyle={Object.assign({backgroundImage: `url(${src})`},style)}{...props}/>exportdefaultBackgroundImage;

<Imagestyle={{width: '50px'}}><BackgroundImage/></Image>
