Applying CRUD operations with the low-level mongodb driver

Again, I won't cover installation of the server software. Please refer to the official installation instructions(https://docs.mongodb.com/manual/installation/) in order to get a MongoDB server up and running on your machine.

Note

If you have Docker installed on your machine, the quickest way to get a MongoDB server up and running is this one-liner:

docker run --rm --name mongo -p 27017:27017 -d mongo:3.4  

See https://hub.docker.com/_/mongo/ for more details.

Once this is done, create a new project folder called mongodb-test, and in there create an initial package.json as follows:

{ 
   "name": "mongodb-test", 
   "version": "0.0.1",
   "description": "", 
   "dependencies": { 
     "mongodb": "^2.2.22" 
   }, 
   "devDependencies": {} 
 }

As always, we pull in the dependencies with

npm install

Now we can create a first program in file index.js:

'use strict';

var MongoClient = require('mongodb').MongoClient;

MongoClient.connect(
    'mongodb...
