title: How to implement service(concept in AngularJS) -like component in React
body: <p>All:</p>
  
  <p>I am pretty new to React from AngularJS.  In AngularJS, there is service dependency inject which can provide a service instance to do data fetching, processing, etc., other than UI operation. I wonder how to do this(or implement that injection) in React component?</p>
  
  <p>Thanks</p>
