title: How to avoid getting error 'localStorage is not defined' on server in ReactJS isomorphic app?
body: <p>I was using localStorage in my webApp to store data on client side. But when I've tried to make the app isomorphic, this causes an issue. Due to node is not browser environment, it can't define such objects as 'window', 'localStorage' etc.
  How do I solve this issue?</p>
