Solution

To connect to MySQL server, we will create a connection with mysql module. So, first include the mysql module, then call the create connection method. Here is the sample code to connect to database.

var mysql = require("mysql");
var con = mysql.createConnection({
    host: "hostname",
    user: "username",
    password: "password",
    database: "database"
});
con.connect(function(err){
    if(err) {
        console.log('Error connecting to Db');
        return;
    }
    console.log('Connection Established');
})
con.end(function(err) { 
});
