Node JS and mysql not connecting (client does not support authentication protocol requested by server consider upgrading mysql client)










1















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:



//Gebruik mysql npm module voor de mysql database
const mysql = require('mysql');

//Geef connectie details aan
var connection = mysql.createConnection(
host : 'localhost',
user : 'root',
port : '3306',
password : 'tombal10',
database : 'fys'
);


connection.connect((err) =>
//Als er geen error is print dan 'Database is geconnect!'
if(!err)
console.log('Database is geconnect!');
//Als er wel een error is print dan 'Database connectie niet gelukt!'
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 :



error image



Does anyone know how I can fix this error and get a connection with my mysqldatabase in nodejs ?



Any kind of help is appreciated
