connection.connect(function(err) {

if (err) { return console.error('error: ' + err.message); }

console.log('Connected to the data_base server.');

});

The connect() method accepts a callback function that has the err argument which provides the detailed error if any error occurred.

If the program shows the following result, the program is successful:

> node connect.js

Connected to the data_base server
