Redux higher order components

Sometimes we need to share props and behaviour between multiple components/containers. For that we can do a higher order component. Example:

Decorator component

Higher Order Component that will decorate other component:

class Image extends Component {
  componentDidMount() {
    // if image hasn't completed loading, then let react handle error
    if (!this._image.complete) return;
    // if image has finished loading and has 'errored'(errored when naturalWidth === 0)
    // then run the onError callback
    if (this._image.naturalWidth === 0) {
      this.props.onError();
    }
  }
