title: How can I use Firebase Functions to send FCM to user?
body: <p>Firebase currently rolled out <strong>Firebase Functions</strong> to add server side code</p>
  
  <p><a href="https://firebase.google.com/docs/functions/" rel="noreferrer">Firebase Functions</a></p>
  
  <p>I was wondering if there could be a way to call FCM notifications through those functions when there is some change in database.</p>
