I think it's better to use router.post

For example:

router.post("/update/:id", (req, res) => {
  conn.query(
    "select * from mahasiswa where ? ",
    { no_induk: req.params.id },
    function (err, rows, field) {
      if (rows.length) {
          let html = view.compileFile("./tamplate/form_update.html")();
          res.writeHead(200, { "Contact-Type": "text/html" });
          res.end(html);
        }
      }
});
