Question

I'm trying to connect my database with node js but it is giving me this error. here is my code

 //to connect to sql var mysql=require('mysql'); var conn=mysql.createConnection({ host:"localhost", user:"root", password:"", database:"bns" }); conn.connect(function (err) { if (err) { console.log(err); return; } console.log("connected"); conn.query("SELECT * FROM employee", function (err, recordset) { if (err) { console.log(err); } else { console.log(recordset); } conn.close(); }); });

and I'm getting this error

Answer 1

var conn=mysql.createConnection({
   
    host:"localhost",
    user:"root",
    password:"",
    port: 3306,
    database:"bns"
    
});

I've had an exactly same issue.

var conn=mysql.createConnection({

host:"127.0.0.1",
user:"root",
password:"",
database:"bns"
});
