Answer 1

Use the new mysql2 library instead of mysql in order to use the new authentication method of MySQL 8.0

~ Tested in node version 13.6.0 and MySQL 8.0.21

Answer 2

Instead of

mysqlConnection.connect((err) => {

use

connection.connect((err) => {

if(!err)
    console.log('Database is connected!');
else
    console.log('Database not connected! : '+ JSON.stringify(err, undefined,2));
});

[Here the is tutorials reference for the code]1

For your mysql error:

Execute the following query in MYSQL Workbench:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password'

Try connecting using node after you do so.

Answer 3

I was having the same problem with mysql library and I fixed that error by changing to mysql2 Library I recommend you to install mysql2

Run

npm install mysql2

Then

import mysql from "mysql2";

OR

const mysql = require("mysql2")

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YourRootPassword';
-- or
CREATE USER 'foo'@'%' IDENTIFIED WITH mysql_native_password BY 'bar';
