What is Nodemon?

Nodemon is a tool that supports hot reload in Node.js backend applications. It means you don't need to close and restart your application for changes to take effect. The server automatically restarts and applies changes when a file is modified.

Install Nodemon globally using npm:
npm i nodemon -g

Node.js 18.11+ introduces a built-in --watch feature for hot reloading.
You can use the following command instead of Nodemon:
node --watch fileName

Nodemon simplifies development by automatically restarting the server on file changes. In Node.js 18.11 and later, you can use the built-in --watch flag as an alternative to achieve hot reload.

console.log("Nodemon simulation...");
console.log("In a real environment, saving this file would restart the process.");
