So I need to render header.ejs in the partials folder, but I need it to be rendered by each page separately. That is localhost:3000/all and here to be rendered header.ejs next to the file dedicated to the page (all.ejs)

i wont like this:

app.get("/all", function (req, res) {
  Product.find({}, (err, product) => {
    if (req.isAuthenticated()) {
      User.findById(req.user.id, (err, user) => {
        res.render("all", {
          isLogIn: true,
          name: user.name,
          product: product,
        });
      });
    } else {
      res.render("all", {
        isLogIn: false,
        product: product,
      });
    }
  });
});

Thanks!
