Next page links with pagination

I've implemented pagination into my controller file

exports.products = async (req, res) => {
  const pagination = req.query.pagination ? parseInt(req.query.pagination) : 5;
  const page = req.query.page ? parseInt(req.query.page) : 1;
  const prod = await Product.find({})
    .skip((page - 1) * pagination)
    .limit(pagination);
  res.render("products", {
    productsList: prod,
  });
};

The code above works, I can access 5 results per page by changing the URL from /products?page=1 to /products?page=2 etc. but I haven't been able to find any information/tutorials that include how to implement the 'next page' links. What I mean is if I have 20 products and want to display 5 products per page, how can I make sure there won't be more than 4 'next page' links at the bottom. Do I have to calculate the number of pages inside my controller and pass that as a variable to my ejs and display the correct amount of links?

I'm just trying to make sure I take the correct approach to this with scaling in mind since I'm relatively new to this! Any help is appreciated

it is good you alreade return the product inside some object. you can use it to also return a count:

  res.render("products", {
    productsList: prod,
    count: await Product.count({})
  });

devided by 'pagination' is the page count.
