Make Connection Pooling on Mongoose

I want to make connection pooling on MongoDB. I am on node environment and using mongoose package for interaction with MongoDB. I am able to interact with one instance of MongoDB.

How I can interact with two instance of MongoDB?

Two instances will be on different port

var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');
var MongoStore = require('connect-mongo')(session);
var mongo = require('mongodb');
var mongoose = require('mongoose');
mongoose.Promise = global.Promise;
mongoose.connect('mongodb://127.0.0.1/db1', { useMongoClient: true });
var db = mongoose.connection;

This is my Implementation of interacting with MongoDB one instance.

There is two way to connect to mongodb database using mongoose.

The one you are using

mongoose.connect('mongodb://127.0.0.1/db1', { useMongoClient: true });
var db = mongoose.connection;

The connection object is stored directly into the mongoose package.

The other

  const connection1 = mongoose.createConnection(url, opt);
  const connection2 = mongoose.createConnection(url, opt);

  connection1.once('open', () => {
      // We are connected
  });

  connection2.once('open', () => {
      // We are connected
  });

Where the connections objects are handled directly by yourself

See the Multiple connections part in mongoose documentation
