Answer 1

I am sending an API that is on MongoDb and Nodejs.

module.exports.fetchLoans = function(req, res, next) {
    var perPage = 5;
    var page = req.body.page || 1;
    loans
      .find({ userId: req.user._id})
      .select("-emi")
      .skip(perPage * page - perPage)
      .limit(perPage)
      .sort({ timestamp: -1 })
      .exec(function(err, loan) {
        if (loan != null) {
          loans
            .find({ userId: req.user._id})
            .count()
            .exec(function(err, count) {
              if (count != null) {
                res.json({
                  success: true,
                  loans: loan,
                  currentpage: page,
                  totalpages: Math.ceil(count / perPage)
                });
              } else {
                console.log("Milestone Error: ", err);
                res.json({ success: false, error: "Internal Server Error. Please try again." });
              }
            });
        } else {
          console.log("Milestone Error: ", err);
          res.json({ success: false, error: "Internal Server Error. Please try again." });
        }
      });
  };

In this code, you will have to provide page number on every hit.
