Shows db is not defined while inserting data to mongoDB

I am learning node js and mongoDb. I am trying to insert data using mongoose but while inserting it show error db is not defined. i am not able to figure out mistake. I have tried all my solution as i could try as a beginner.

var mongoose = require("mongoose"); // require mongoose

mongoose.connect('mongodb://localhost:27017/mydatabase', {useNewUrlParser: true});

const myConnection = mongoose.connection;

// Create Schema
var employeeSchema = new mongoose.Schema({
name: String,
email: String,
eType: String,
hourRate: Number,
totalHour: Number,
});


employeeSchema.methods.totalSalary = function () {
var total = employee.hourRate * employee.totalHour;
console.log(`total Salary is = ${total}`);
};

var employeeModel = mongoose.model("Employee", employeeSchema);

var employee = new employeeModel({
name: "Akash Jangra",
email: "[email protected]",
eType: "Hourly",
hourRate: 500,
totalHour: 70,
});

// console.log(employee)
employee.totalSalary();

 myConnection.on('Connect', function(){
console.log('Connected Successfully')
 });

  myConnection.on('disconnect', function(){
console.log('Disconnected')
 })

  myConnection.on('error', console.error.bind(console, 'connection error:'));

  db.once('open', function() {
  // we're connected!
   employee.save(function(err, res) {
    if (err) throw error
    console.log(res)
    myConnection.close()
   })

I think you're referring to the wrong variable here.

myConnection.once should work. You have not declared db anywhere in your code.
