Insert A Record Into MySQL Database from Server POST Request (Node + MySQL)

There are 2 ways to insert data from the req.body of a route:

Method #1

router.post('/', (req, res) => {
    const userInfo = req.body;

    const sql = "INSERT INTO users SET ?";

    mysqlConnection.query(sql, userInfo, (err, rows, fields) => {
        if (!err) {
            res.send(rows);
        } else {
            console.log(err.message);
            res.send(err);
        }
    })
});

Method #2

router.post('/', (req, res) => {
    const { name, username } = req.body;

    const sql = "INSERT INTO users (name, username) VALUES ('${name}', '${username}')";

    mysqlConnection.query(sql, (err, rows, fields) => {
        if (!err) {
            res.send(rows);
        } else {
            console.log(err.message);
            res.send(err);
        }
    })
});
