node.js MySQL connection not established - only when using XAMPP - mysql

Question

I'm trying to establish a MySQL connection with my node.js server, but when I do, I get the following error:
F:\Programmering\nodejs-server>node dbConnection.js
F:\Programmering\nodejs-server\dbConnection.js:10
if (err) throw err;
^
Error: connect ECONNREFUSED 127.0.0.1:3306

I've tried using other ports, but still same error message. When I use XAMPP, and start MySQL service, it connects fine. These are the messages when I install mysql using npm:
F:\Programmering\nodejs-server>npm install mysql
npm WARN nodejs-server#1.0.0 No repository field.
+ mysql#2.15.0
added 11 packages in 7.809s
I have been using the w3schools tutorial. This is my code:
var mysql = require('mysql');
var con = mysql.createConnection({
host: "localhost",
user: "myusername",
password: "mypassword"
});
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
What am I doing wrong? Please help! Thank you!
