Sample Mongo java client using replica set

Connect.js

const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');

// Connection URL
const user = encodeURIComponent('username');
const password = '************';

const url = `mongodb://${user}:${password}@d7mongo41.company.com:27017,d7mongo41.company.com:27018,d7mongo41.company.com:27019/?authSource=dome&replicaSet=rs0`;
//const url = `mongodb://${user}:${password}@d7mongo41.company.com:27017?authSource=admin`;

console.log(url);

const dbName = 'somedb';
const client = new MongoClient(url, {useNewUrlParser: true});
client.connect(function(err) {
  assert.equal(err, null);
  console.log("Connected successfully to server");


  const db = client.db(dbName);
  db.listCollections().toArray(function(err, collInfos) {
     console.log(collInfos);
  });
});
