API by an example

The component to print

We want to draw this Component (Component.jsx):

import React from 'react'

export default ({ onError, src }) => {
  return (
    <div className="my-component">
      <img
        src={src}
        onError={onError}
      />
    </div>  
  )
}

• onError is injected by hoc-react-img-fallback
• src is injected by our parent component

The fallback component, printed when the first component has an error

If there is an error, we draw this fallback Component (Fallback.jsx):

import React from 'react'

export default ({ src }) => {
  return (
    <div className="my-error">
      {'Sadly we can\'t print this image :'} {src}
    </div>  
  )
}

• src is injected by our parent component

The mixed component

Image.jsx

import fallback from 'hoc-react-img-fallback'
import Component from './Component'
import FallbackComponent from './Fallback'

export default fallback(Component, FallbackComponent)

• First argument is the Component we try to print
• Second argument is the FallbackComponent if the first one is on error

The parent component

Parent.jsx

import React from 'react'
import Image from './Image.jsx'

export default () => {
  return (
    <div className="my-parent">
      {/* This image is on error and prints the Fallback Component */}
      <Image src="http://unknonwn.link/oups" />

      {/* This image is printed because there is no error */}
      <Image src="https://www.google.fr/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png" />
    </div>
  )
}
