How to connect azure mysql server with nodeJS - mysql

Question

I am trying to connect to a remote mysql server with nodejs
So far I am able to connect with mysql workbench 8.0, so no problem with mysql server. And I can easily connect to my local mysql-server (with "mysql2" module).
Here is something I've been trying to connect with remote mysql server provided by Azure. I followed the guides that is provided.
const mysql = require("mysql");
const fs = require("fs")
var connection = mysql.createConnection({
host: process.env.MYSQL_SERVER_HOST,
user: process.env.MYSQL_SERVER_USER,
password: process.env.MYSQL_SERVER_PASSWORD,
database: process.env.MYSQL_SERVER_DATABASE,
port:3306,
ssl: { ca: fs.readFileSync("./certificates/DigiCertGlobalRootCA.crt.pem")}
});
// This is how I am connecting to my local mysql-server which is working fine
// // const connection = mysql.createConnection({
// host: 'localhost',
// user: 'root',
// password: process.env.LOCAL_MYSQL_SERVER_PASSWORD,
// database: 'db',
// port: '3306'
// });
connection.connect((error) => {
if (error) {
console.log("mysql error")
console.log(error)
}
else {
console.log("Mysql Ready")
}
});
module.exports = connection;
Here I am using mysql package because many articles on web suggested it but I even used mysql2 and nothing happened. I even changed the networking setting and allowed my IP address for access(this wasn't necessary though).
Error logs:
mysql error
