This example uses react-transition-group to animate navigation transitions.

The location.pathname from the response is used to uniquely identify the content. The pathname is used instead of the key so that navigating to the same pathname as the current pathname does not cause a transition.

function render({ response }) {
  const { body:Body } = response;
  return (
        <Body response={response} />
