title: NodeJS changes not reflected on server
body: <p>I'm running NodeJS application on CentOS with PM2. Everything works fine.</p>
  
  <p>But I made a query changes in one of the controller file (add new column in SQL query). And then uploaded the project files to server. And then run PM2 restart [app-id].</p>
  
  <p>It's strange that new column was not returned in the api response payload.</p>
  
  <p>Is there anyway to clear cache of PM2? or What is the issue exactly?</p>
  
  <p>Please advise!</p>
