app.post("/register", (req, res) => {
  let id = req.body.id;
  let name = req.body.name;
  let email = req.body.email;
  cmd = "INSERT INTO emp VALUES(?, ?, ?)";
  conn.connect((err) => {
    if (err) throw err;
    let con = conn.query(cmd, [id, name, email], (err, res) => {
      if (err) throw err;
      console.log(res);
    });
  });
});

I have a post endpoint which executes a query. It takes id, name and email from user and stores in database. So, how do I tell user that their data has been saved. In other words, how to send a “Hi your data has been saved” text or even html.

I tried adding app.get inside app.post but it didn’t work.
