NodeJS + MongoDB. How to properly "close" client.close?

Question

JavaScript

Actually there is a node, there is a mongodb module, there is a construction https://jsfiddle.net/x4f513gj/1/
In which part of the code is it more correct to use client.close() ? Thanks in advance for your reply.

Answer 1

Why close it at all? Connect once and that's it.

Answer 2

You do db.open() at startup and don't close the connection at all. This is the right approach
