How to implement object mapper in node.js

I have MongoDb as my db . data in this instance is populated on a daily basis through a csv file import.

a document in this collection/csv looks as

    {
    "_id": {
        "$oid": "611e455ddd7c222661065037"
    },
     "country": "India",
     "country_code": 91,
     "country_iso": "IND",
     "origination_prefix": "",
     "voice_rate_in_usd": 0.3148,
     "voice_unit_in_seconds": 60
    }

This data is fetched via node.js api as below

    //some code emitted for brevity
    import { connect, Schema, model } from "mongoose";
    import express from "express";

    const router = express.Router();

    const schema = new Schema<Pricing>({
    country: { type: String, required: true },
    countryCode: { type: String, required: false },
    countryIso: { type: String, required: true },
    destinationPrefix: { type: [Number] },
    voiceRate: { type: Number },
    voiceUnit: { type: Number },
    });

    const pricesModel = model<Pricing>("call_rate", schema);

    router.get("", async (req, res) => {
     const prices = await pricesModel.find().limit(10);
     res.send(prices);
    });

    export default router;

Being a newbie to node.js on googling I get a number of packages

now I am not sure which is the most common/popular/recommended package & how do I use it

How can I map my DB object to the app object?

Thanks!

Since you are using MongoDB and Mongoose, you don't have to do anything. Mongoose will automatically return objects or array of objects for each query.
