I am creating a MERN Stack Application which gives 'Points' to a User based on how many Posts, Comments and Likes they do.

I need to generate a LEADERBOARD from this, that Ranks all the Users (User with the most Posts, Comments & Likes) and also shows the sum count of Post, Comments & Likes.

Currently I have a userSchema as per below:

import mongoose from 'mongoose'
const { Schema } = mongoose

const userSchema = new Schema(
  {
    name: {
      type: String,
      trim: true,
      required: true,
    },
    email: {
      type: String,
      trim: true,
      required: true,
      unique: true,
    },
 
const postSchema = new mongoose.Schema(
  {
    user: {
      type: mongoose.Schema.Types.ObjectId,
      ref: 'User',
    },
    title: {
      type: String,
      required: true,
    },
    comments: [
      {
        content: 'String', 
        user: {
          type: mongoose.Schema.Types.ObjectId,
          ref: 'User',
        },
      },
    ],
    likes: [
          {
            user: {
              type: mongoose.Schema.Types.ObjectId,
              ref: 'User',
            },
          },
        ],

      }
    );

How do I list out in a LEADERBOARD all the Users and Rank them based on their TOTAL POINTS (sum of number of posts, comments & likes)?
