title: How to create schema for neo4j graph database in nodejs?
body: <p>I was thinking, How we can prevent user/developer from adding unwanted nodes/relationships/properties? </p>
  
  <p>What I read was - we should impose those schema's at application level. So, how can we do that in Node.js?</p>
  
  <p>Is there any example on this? Or can someone post some code here?</p>
