Create Connection

Create a folder named “DBexample”. In that folder create a js file named “connection.js” having the following code:

var mysql = require('mysql');  

var con = mysql.createConnection({  

  host: "localhost",  

  user: "root",  

  password: "12345"  

});  

con.connect(function(err) {  

  if (err) throw err;  

  console.log("Connected!");  

});

Now open the command terminal and use the following command:

Node connection.js

Now Node.js is connected with MySQL.
