title: How to get initial data from api before app loaded in next.js
body: <p>I want to load some data from api before application rendered. </p>
  
  <p>Yes, I know we can do it in getInitialProps method of component, but I don't want load it on each component loading,
  I need make only 1 api call and make accessible retrieved data among all components. What is the easiest way to do it?</p>
