title: CRUD operations using DynamoDB with expressjs (node js)
body: <p>I am trying to create a route which will perform some CRUD operations on DynamoDB.
  At high level , it can be understood as :</p>
  
  <ol>
  <li>The node js server application is running .(i.e. command 'node server.js' is being triggered)</li>
  <li>The user uses POSTMAN of chrome browser to do route requests.</li>
  <li>The user does a GET request for '<a href="http://localhost:8080/listtablesofdynamodb" rel="noreferrer">http://localhost:8080/listtablesofdynamodb</a>'.</li>
  <li>The specific route connected with this url gets hit which should do dynamodb specific activity. (like connecting to dynamodb ,fetching table names and showing it in callback method.)</li>
  </ol>
  
  <p>the reason I am asking this question is because I could not find any relevant tutorial of how to do dynamodb activity by using express js of node. All I could find is console applications on aws website which seems not useful for me.
  Any kind of help is highly appreciated. </p>
