This is working fine:

var options = { server: { socketOptions: { keepAlive: 1 } } };
var connectionString = 'mongodb://admin:admin1234@localhost:27017/myDB';

 mongoose.connect(connectionString, options);

//Add those events to get more info about mongoose connection:

// Connected handler
mongoose.connection.on('connected', function (err) {
  console.log("Connected to DB using chain: " + connectionString);
});

// Error handler
mongoose.connection.on('error', function (err) {
  console.log(err);
});

// Reconnect when closed
mongoose.connection.on('disconnected', function () {
   self.connectToDatabase();
});
