Installing MongoDB on Windows.

Download MongoDB from its download page, and install it. I chose to install in C:\opt\MongoDB\Server\3.2.

Create a folder for database and a folder for logs. Then create a mongod.cfg to represent this data.

In my case, I put all under a new C:\data\ directory.

c:/data/
  db/
  logs/
  mongod.cfg

And this is the content of mongod.cfg

systemLog:
    destination: file
    path: c:\data\log\mongod.log
storage:
    dbPath: c:\data\db

Install MongoDB as service

Open the command prompt with administrative privileges, and type:

"C:\opt\MongoDB\Server\3.2\bin\mongod.exe" --config "C:\data\mongod.cfg" --install

Verify mongodb is installed. Open command prompt with Win + R, then type services.msc

If you see MongoDB in the list, it is installed as service

Start and Stop and Admin DB

If you installed MongoDB as a service, to start and stop, you need to open the command prompt as admin:

net start MongoDB

net stop MongoDB

Otherwise, you start MongoDB via command line.

"C:\opt\MongoDB\Server\3.2\bin\mongod.exe" --config "C:\data\mongod.cfg"

In this case, to stop, you need to launch the mongo shell

>"C:\opt\MongoDB\Server\3.2\bin\mongo.exe"

And stop the server with the below commands:

MongoDB shell version: 3.2.10
> use admin
> db.shutdownServer()

Admin MongoDB

When MongoDB is running, you can manage it using the mongo Shell. Go to the mongodb install dir, in my case C:\opt\MongoDB\Server\3.2\, and type:

.\bin\mongo

From the shell, you can manage your dbs. Now, we create a new database and insert new data.

> use myNewDatabase
switched to db myNewDatabase
> db.myCollection.insert({myData:1});
WriteResult({ "nInserted" : 1 })

Test NodeJS app with MongoDB

Now we use mongodb in a test NodeJS application.

to run the application, you need to install mongodb and assert modules, either via npm install <module> or via package.json addition and installation .

//lets require/import the mongodb native drivers.
var mongodb = require('mongodb');
var assert = require('assert');

//We need to work with "MongoClient" interface in order to connect to a mongodb server.
var MongoClient = mongodb.MongoClient;

// Connection URL. This is where your mongodb server is running.
var url = 'mongodb://localhost:27017/myNewDatabase';

// Use connect method to connect to the Server
MongoClient.connect(url, function (err, db) {
  if (err) {
    console.log('Unable to connect to the mongoDB server. Error:', err);
  } else {
    //HURRAY!! We are connected. :)
    console.log('Connection established to', url);

    // do some work here with the database.☺

    //Close connection
    db.close();
  }
});

Congratulations, you just connected to your new MongoDB database.
