Connectivity issue for MySQL 8.0 and Node JS using Express - mysql

Question

I was trying out fetching the information from MySQL 8.0 table into Node JS using Express. But I am constantly getting the error ER_NOT_SUPPORTED_AUTH_MODE. I tried many things such as:
Changing the authentication method for an individual user (and used multiple different users) - changed it from SHA 256 to Caching 256 and to default one (mysql_native_password) neither of them works.
Changing my Node js code: instead of using the single connection which was giving me the error - PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR, I changed it to pool of connection but still getting the error ER_NOT_SUPPORTED_AUTH_METHOD.
I found out that MySQL Server uses SHA 256 password private key and public key, but I don't know how to implement it or use it in Node. js.
My database table: react_test
product_id | product_name | product_price
1 | abc | 10
Here is my Node.js code:
const express = require('express');
const cors = require('cors');
const mysql = require('mysql');
const app = express();
const SELECT_ALL_QUERY = 'SELECT * FROM project.react_test';
const connection = mysql.createConnection({
host:'localhost',
user:'avd',
password:'password',
database:'project',
insecureAuth : true
});
const pool = mysql.createPool({
host : 'localhost',
user : 'avd',
password : 'password',
authentication_string : 'root',
insecureAuth : true
});
//var pool = mysql.createPool(connection);
connection.connect(err => {
if(err) {
return err;
}
})
console.log(connection);
app.use(cors());
app.get('/', (req,res) => {
res.send('hello from product server')
});
app.get('/hola', (req,res) => {
res.send('hola')
});
app.get('/hotels_info', (req,res) => {
connection.query(SELECT_ALL_QUERY, (err, results) => {
if(err){
return res.send(err)
} else {
return res.json({
data: results
})
}
});
});
app.listen(4000, () => {
console.log('Product server listining port 4000');
});
Error when using single connection: {"code":"PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR","fatal":false}
Error when using pool of connection:
{"code":"ER_NOT_SUPPORTED_AUTH_MODE","errno":1251,"sqlMessage":"Client does not support authentication protocol requested by server; consider upgrading MySQL client","sqlState":"08004","fatal":true}
I dont know what to do further! Please guide me! Thank you in advance!
