JS -

var mysql = require('mysql');
var con = mysql.createConnection({
    host: 'localhost', 
    user: 'root', 
    password: '*****', 
    database: 'mydb'
    });

con.connect(function(err) {
    if (err) throw err;
    console.log("Connected!");
});

Answer 1

There is no prolem in your node.js

node.js require only mysql installation

-> go to installation of nodejs in the command prompt and enter

 npm install mysql 

in Eclipse: 1) install the nodejs plugin 2) open package.json in the nodejs project and enter

       "author": "Krish",
       "dependencies": {
                "mysql": "2.x.x"
      },

3) right click on the project run -> node install

it will install the mysql and you are ready to connect the Database

ER_ACCESS_DENIED_ERROR

1) go to mysql command prompt

   mysql> create user 'root'@localhost IDENTIFIED BY 'password';

2) give permission

   mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT 
        OPTION;

or

   mysql>SHOW GRANTS FOR 'root'@'localhost';

now you can run you JS . it will be conneced

Answer 2

If you hosting SQL in xampp then the root user in localhost does not have any password, so remove the password.

It worked for me.
