"use strict";
const MongoClient = require('mongodb').MongoClient;

const dbUrl = 'mongodb://127.0.0.1:27017/cs602';

MongoClient.connect(dbUrl,  (err, db) => {
    if (err)
    {throw err}else {
        console.log('Successfully connected to',
            db.s.databaseName);
    }
    // Do database operations
    db.close();
});

This error could be caused by the MongoDB's bind IP setting. You can check MongoDB's config file. But the truth is i don't know is located in Windows systems.

In my case, the bind IP is set to localhost address, just as following:

# /usr/local/etc/mongod.conf
net:
  bindIp: 127.0.0.1
