About node.js with mysql

Question

I'm using node.js with mysql database.

I'm using the config like this:

var mysql = require('mysql');
var client = mysql.createConnection({
     host: 'localhost',
     user: 'root',
     password: 'java1234',
     port: '3306',
     database: 'sample'
});

and then I get these error messages:

Error: ER_ACCESS_DENIED_ERROR: Access denied for user 'root'@'localhost' (using password: NO) at Handshake.Sequence._packetToError (C:\node\test11_users\node_modules\mysql\lib\protocol\sequences\Sequence.js:47:14) at Handshake.ErrorPacket (C:\node\test11_users\node_modules\mysql\lib\protocol\sequences\Handshake.js:124:18) at Protocol._parsePacket (C:\node\test11_users\node_modules\mysql\lib\protocol\Protocol.js:278:23) at Parser.write (C:\node\test11_users\node_modules\mysql\lib\protocol\Parser.js:76:12) at Protocol.write (C:\node\test11_users\node_modules\mysql\lib\protocol\Protocol.js:38:16) at Socket.

but I can't solve this problem. thanks for your explain easily.

It basically means your credentials are not correct. Are you able to access mySQL outside? — Atishay Jain

Remove port from connection options and try

var mysql      = require('mysql');
var connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'root',
  password : 'java1234',
  database : 'sample'
});

connection.connect();
