I'm trying to connect my NodeJs application with a mysql database but its not connecting for some reason.
I did install the mysql npm like this (typed this in commandline):
npm install mysql
After I installed the mysql npm I made an index.js file and in that file I tried to make the connection with my database.
This is the code inside my index.js file to make a connection with mysql:
const mysql = require('mysql');
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
port : '3306',
password : 'test12310',
database : 'fys'
});
connection.connect((err) => {
if(!err)
console.log('Database is geconnect!');
else
console.log('Database connectie niet gelukt! : '+ JSON.stringify(err, undefined,2));
});
Then I tried to run the code and see if the connection with mysql worked. I typed this in the command line:
node index.js
This is the error message I got in the command prompt :
Does anyone know how I can fix this error and get a connection with my mysqldatabase in nodejs ?
Any kind of help is appreciated
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
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")
I hope this will work for you!! Good Luck
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));
});

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