I can’t connect to my local MySQL Server through Javascript.

I tried to connect to my mySQL instance with following code:

const mysql = require("mysql2");
// create a new MySQL connection
const connection = mysql.createConnection({
    host: "localhost",
    user: "js",
    password: "js_sql",
});
// connect to the MySQL database
connection.connect((error) => {
    if (error) {
        console.error("Error connecting to MySQL database:", error);
    } else {
        console.log("Connected to MySQL database!");
    }
});
// close the MySQL connection
connection.end();

Output:

Error connecting to MySQL database: Error: connect ECONNREFUSED 127.0.0.1:3306
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1595:16) {
  errno: -111,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 3306,
  fatal: true

If i try to connect with the same credentials in my workbench, it works.

PS: My project folder is in my WSL!
