Memposting data Formulir ke MySQL menggunakan nodejs w/ Express

Seharusnya begini,

app.post('/data', function(req, res){
    var username=req.body.name;
    connection.query("INSERT INTO `names` (name) VALUES (?)", username.toString(), function(err, result){
        if(err) throw err;
            console.log("1 record inserted");
        });
    res.send(username);
});
