title: Pass variable from express server to react application
body: <p>So I am using 
  <a href="https://github.com/ctrlplusb/react-universally" rel="nofollow noreferrer">react universally</a> and I want to pass some variable value to the react application from the server without having to do an ajax request after it's loaded. The react application is loaded like:</p>
  
  <pre><code>const someVariable = 'some variable';
  // The React application middleware.
  app.get('*', reactApplication);
  </code></pre>
  
  <p>How can I pass it to down so that it will be available in the react application?</p>
