First install the mongoose module by doing

npm i mongoose

in the project directory. Let us check it by example:

"use strict";
/*
 * include more sophisticated mongodb functionality
 * mongoose enforces schemas, mongodb doesn't
 */
const mongoose = require("mongoose");

/*
 * create schema for database object
 * build corresponding model as an object
 * Wex19, lesson 14
 */
const carSchema = mongoose.Schema ({
    carType: String,
    notes: String,
    range: Number,
    created: {type: Date, default: Date.now}
});
const Car = mongoose.model("Car", carSchema, 'car');

/*
 * connect to mongodb server
 */
const dbname = "test111";
const constr = `mongodb://localhost:27017/${dbname}`;
const conparam = { useNewUrlParser: true, useUnifiedTopology: true };
mongoose.connect(constr, conparam);
const db = mongoose.connection;
db.once("open", function() {
    console.log("Connected to server by mongoose")
});
/*
 * create concrete object
 */
var car1 = new Car({
    carType: "SUV",
    notes: "my Suzuki",
    range: Math.random() * 600
});

/*
 * Utility function to reformat mongdb dates which are in ISO8601 fmt
 * totally unrelated to mongoose :)
 */
const dateConverter = function(dato) {
    let dstr = "";
    if (dato.getDate() < 10) {
        dstr += "0" + dato.getDate();
    } else {
        dstr += dato.getDate();
    }
    dstr += "/";
    if (dato.getMonth() < 9) {
        dstr += "0" + (dato.getMonth() + 1);
    } else {
        dstr += (dato.getDate() + 1);
    }
    dstr += "/" + dato.getFullYear();
    return dstr;
}

/*
 * insert car1 object into database, the C of CRUD
 * save is a mongoose method
 */
car1.save(function(error, savedDocument) {
    if (error) console.log(error);
    console.log(savedDocument);
    var dato = savedDocument.created;

    // checking the date utility
    var dato1 = dateConverter(dato);
    console.log(dato1);
});

/*
 * alternative way of inserting, the C of CRUD
 * create below includes the save functionality
 */
Car.create(
    {
        carType: "Sedan",
        notes: "boring",
        range: Math.random() * 600
    },
    function(error, savedDocument) {
        if (error) console.log(error);
        console.log(savedDocument);

        db.close();     // if forgotten batch job doesn't stop by itself

    }
);

console.log("Asynchronous? If I come first, yes!");

Again first install the mongoose module by doing

npm i mongoose

in the project directory. This example has the useful extra benefit that it exemplifies.

"use strict";
// https://thecodebarbarian.com/how-find-works-in-mongoose

/*
 * include more sophisticated mongodb functionality
 * mongoose enforces schemas, mongodb doesn't
 */
const mongoose = require("mongoose");
const constr = "mongodb://localhost:27017";
const conparam = { useNewUrlParser: true, useUnifiedTopology: true };

const tester = async function (dbname) {
    /*
     * create schema for database object
     * build corresponding model as an object
     * Wex19, lesson 14
     */
    const carSchema = mongoose.Schema ({
        carType: String,
        notes: String,
        range: Number,
        created: {type: Date, default: Date.now}
    });
    const Car = mongoose.model("Car", carSchema, 'car');

    /*
     * connect to mongodb server
     */
    await mongoose.connect(constr + "/" + dbname, conparam);
    const db = mongoose.connection;
    db.once("open", function() {
        console.log("Connected to server by mongoose")
    });


    const arr = await Car.find({}, null, {sort: {range: 1, created: -1}});
    console.log(arr)
    db.close();
}
console.log("Asynchronous? If I come first, yes!");
tester("test111").catch(error => console.log(error.stack));
