Trying to get user history of my app

getHistory.js

// I use passport as auth so req.user is set by it.
// Is this code feasible enough when the user has many farms with different crops, i.e when the user data grows
// As of now the code taken up to 1412 ms to complete
const { Farm } = require('../models/farm');

getHistory = function(req, res, next) {
  Farm.find().distinct('cropId', { userId: req.user._id }, (err, cropIds) => {
    if (err) return res.send({ success: false, err });
    let i = 0;
    let data = [];
    cropIds.some((entry, index) => {
      data.push(
        new Promise(function(res, rej) {
          Farm.aggregate(
            [

                $match: {

module.exports = getHistory;

Not bad but creating promises for each entry? Is it possible to create a single promise that can be used for each data
