Server

First we need to install MongoDB on our computer.

After installation do the following things:

• We use 'Mongoose' lib:

  var mongoose = require('mongoose');

• Use Mongoose:

  //Use Mongoose mongoose.connect('mongodb://localhost/multivision'); // will create multivison databse automatically var db = mongoose.connection;

• Listen for some events:

  db.on('error', console.error.bind(console, 'connection error')); db.once('open', function callback(){ console.log('db opened'); });

RUN MongoDB

In the command line:

  mongod    // start the mongoDB
