Creating a Node.js calculator application

Project structure

Project Setup

Create directory and cd to the directory

mkdir my_module
cd my_module

Initialize and install third-party module

npm init -y
npm i chalk

Update the package.json file

{
  "name": "ameh-calculator",
  "version": "1.0.0",
  "main": "app.js",
  "type": "module",
  "scripts": {
    "dev": "node app.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "chalk": "^5.4.1"
  }
}

Create the calculator.js file in the custom module to implement basic arithmetic calculation and export

Create app.js file in the root directory to import the functions

Run the app based on the scripts added in package.json file

npm run dev

Initialize git, add and commit the project to GitHub

git init
git add .
git commit -m "message"

And then push to repo

git remote add origin https://github.com/ameh0429/techcrush assignment.git
git branch -M main
git push -u origin main
