How to change DB connection in node js dynamically?

Question

I have two enterprises, and both have separate DBs. And when I select these enterprises through the drop-down, I want to change my DB connection with that option.

Answer 1

const conn = require('./connection.js'); // your path

 conn.changeUser({database : 'databasename'}, function(err) { 
     if (err) throw err; 
   });
