Tech Stack

• TypeScript - TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

• Express - Node Framweork.

• Nodemon - Use for development file reload.

• Winston - A multi-transport async logging library for node.js.

• mongoose - ODM library for mongoDB.

• Helmet - Library to increase security of node server.

Logging

• winston - a multi-transport async logging library for Node.js. It is designed to be a simple and universal logging library with support for multiple transports. A transport is essentially a storage device for your logs. Each instance of a winston logger can have multiple transports configured at different levels. For example, one may want error logs to be stored in a persistent remote location (like a database), but all logs output to the console or a local file.
• morgan - HTTP request logger middleware for Node.js. A helper that collects logs from your server, such as your request logs.

Tests

• mocha - Test Framweork for JavaScript.
• chai - Assertion library for javascript.

You can call Subtract function so that you need to pass two number which you want to Subtract

const SubtractTwoNumber = async (num1, num2) => {
  const AddNumber = await calculator.Subtract(num1, num2);
  console.log("Subtract Number: ", AddNumber);
};
SubtractTwoNumber(10, 2);

You can call Multiply function so that you need to pass two number which you want to Multiply

const MultiplyTwoNumber = async (num1, num2) => {
  const AddNumber = await calculator.Multiply(num1, num2);
  console.log("Multiply Number: ", AddNumber);
};
MultiplyTwoNumber(3, 4);

You can call Divide function so that you need to pass two number which you want to Divide

const DivideTwoNumber = async (num1, num2) => {
  const AddNumber = await calculator.Divide(num1, num2);
  console.log("Divide Number: ", AddNumber);
