React Image Fallback

React Image Fallback exists for those times that you're just not sure an image will be there. See a simple demo here

Install

npm install react-image-fallback

Required Props

src

A string represent the url to your primary image.

fallbackImage

A string representing the image you want to fallback to if your primary image is not there. Optionally this can also be passed in as a react element. This can also be passed in as an array of string srcs or react elements, the component will attempt to keep trying srcs until a loadable src is found. It should be noted that a react element will always be treated as a loadable src.

Optional Props

initialImage

The image to show before your src or fallbackImage load. Can optionally be passed in as a react element.

initialTimeout

timeout in millisecond before to show initialImage. Default is null which should initialImage immediately

onLoad

A callback called if initial image loads successfully, will be called with successful image url.

onError

A callback called if initial image load fails, will be called with failing image url.

spread props

This component also utilizes jsx spread attributes to pass along custom image attributes such as alt tags and className. Only valid dom props will be spread to the image tag.

Use

import React From "react";
import ReactImageFallback from "react-image-fallback";
export default class ShowImage extends React.Component {
	render() {
		return (
			<div>
				<ReactImageFallback
					src="my-image.png"
					fallbackImage="my-backup.png"
					initialImage="loader.gif"
					alt="cool image should be here"
					className="my-image" />
			</div>
		);
	}
}
