Establishing a connection between Node.js and MySQL - mysql

Question

I'm a complete newbie to Node.js, but I do have some experience with mysql and some other languages.
I am trying to establish a database connection between Node.js and MySQL, however, my terminal keeps on giving me errors. It failed, so I tried to debug it by using "error.stack" as stated from the documentation, that failed also so I'm totally lost now. Can someone please help me to figure out the bug.
Also, can anyone also tell me how to tell Node.js to print out the reason of why it failed to connect to the database like the function "mysql_error()" from PHP.
My original Node.js code:
var MySQL = require('mysql');
var DatabaseConnection = MySQL.createConnection({
host: '10.0.0.25',
user: 'Admin',
password: 'Password'
});
DatabaseConnection.connect(function(error) {
if(!error) {
console.log("Database is connected");
return;
} else {
console.log("Database is not connected: ");
console.log(error.stack);
}
});
My result:
Database is not connected:
Error: connect ECONNREFUSED 10.0.0.25:3306
