Connecting to Azure Database for MySQL in npm/mysql - mysql

I am getting an error when connecting to Azure Database for MySQL with the mysql npm module (version 2.13.0):

Connecting to the database via MySQL Workbench works fine.

This is a known issue as our engineers have a disscusion at https://social.msdn.microsoft.com/Forums/en-US/c8fedbcc-909d-41ce-8c72-0374f76fdf82/cannot-connect-from-nodejs?forum=AzureDatabaseforMySQL.
And currently, I have test the solution provided by #Bradley Grainger at Cannot connect Azure Web App - NodeJS to Azure Mysql. We also can see the gist at https://github.com/mysqljs/mysql/commit/e3e123e9af7c0829a6c1417d911572a75b4a5f95.
Currently, please modify the package.json as:
"dependencies": {
"mysql": "git://github.com/mysqljs/mysql#e3e123e9af7c0829a6c1417d911572a75b4a5f95"
},
then, run npm install to install this version.
It should work as expected.
Additionally, please wait for the maintainer merges this PR.

Having issues with Node JS MySQL connection

I'm creating a discord bot that pulls from a pre-established database of patch note news I have, it's my first time dealing with NodeJS and MySQL. I've got the default connection code in the file right now to test the connection and it looks like this:
require('dotenv').config();
const { Client, Intents } = require('discord.js');
const { token } = require('./config.json');
const mysql = require('mysql');
const client = new Client({ intents: [Intents.FLAGS.GUILDS] });
const con = mysql.createConnection({
host: process.env.HOST,
port: process.env.PORT,
user: process.env.MYSQLUSER,
db: process.env.DATABSE,
password: process.env.MYSQLPASSWORD,
});
con.connect((err) => {
if (err) throw err;
console.log("Connected");
})
I've tried hosting the application local on my machine with a remote connection to the SQL database and on the actual server that it lives on, so far this is all I'm getting:
/home/niemer5/news-bot/node_modules/mysql/lib/protocol/Parser.js:437
throw err; // Rethrow non-MySQL errors

The user exists, it has ALL privileges, I set everything up in cPanel and also tried granting privs in SQL CLI and so far no luck it just errors out with a 1045 access denied error and I have no clue what is happening. Looking for a little guidance here!

I cannot connect to mysql database using node.js

I am total beginner to database.
I am using localhost(127.0.0.1) with port 9090.
I successfully created mysql database, ran/used it in windows 10 command prompt and MySQL Workbench.
But when I try to run it with node.js, I fail to connect to server.
Below is index.js file I tried to run in windows command line.
var mysql = require('mysql');
var client = mysql.createConnection({
user:'root',
password:'password',
});
client.query('USE mydb');
client.query('SELECT * FROM PRODUCTS',function(error, result, fields){
if(error){
console.log(error);
} else{
console.log(result);
}
});
And it results in this error.

I am at the stage not knowing what I am not knowing.
I tried to change port in createConnection() function like this
var client = mysql.createConnection({
user:'root',
password:'password',
port: '9090'
});
Then I get this error.

1.Open your windows terminal and login :
mysql -uroot -p
( then type you password )
use mysql;
update user set authentication_string=password(''), plugin='mysql_native_password' where user='root';
4 Restart you mysql db : sudo service mysql restart
Doing this in MySQL Workbench solved the problem.
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password
BY 'YourRootPassword';
FLUSH PRIVILEGES;

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

I'm trying to establish a MySQL connection with my node.js server, but when I do, I get the following error:

+ mysql#2.15.0

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!

Why is node script failing a localhost connect to MySQL

I can't figure out why a script to is failing to connect to the MySQL instance.
I can connect to the database from the mysql client on the command line, with the exact same credentials.
I can connect to the database from a remote client, using the same credentials.
The database connect script works fine if I set the parameters to a remote database.
Neither host or socket parameters works through the script.
I make dumb mistakes at times but if this is another one, I can't see it.
An outside observer would help me here.

I'm not sure if the error from the socket is a permissions issue or not and if that is relevant.
As it turns out, a check of the my.conf shows that the bind-addresss was set to the IP of the server and not to localhost.
Setting host: '<ip-address>' fixed the issue.

Connecting to wordpress MySQL database with Node.js

At the minute I'm just trying to connect to the database but I am getting a connection refused error.The database is from a wordpress site that was set up and I am trying to connect to that through Node using the node mysql driver - https://www.npmjs.org/package/mysql
The way the user's have looked at the database before was through phpmyadmin and im not sure what to use as the hostname for a database like this. i have tried using the server name given to me - cust-mysql-123-14 but that just gives me a address not found error obviously. The only other information i have about the server is this address;
linweb14.atlas.pipex.net
When i connect with that it then throws up this error;
error connecting: Error: connect ECONNREFUSED

var mysql = require('mysql');
var connection = mysql.createConnection(
{
host : 'hidden',
user : 'hidden',
password : 'hiddden',
database : 'hidden',
port : 3000
}
);
connection.connect(function(err) {
if (err) {
console.error('error connecting: ' + err.stack);
return;
}
console.log('connected as id ' + connection.threadId);
});
Any ideas or advice on where I'm going wrong?
