i have checked dependencies installed nodemon using npm i -D nodemon when i typed nodemon.\index.js my live server should run but it is not[

Answer 1

The reason is Powershell does not aware of nodemon. Currently nodemon is installed in your project directory.

I would suggest you to a script in package.json

"scripts": {

   "start-nodemon": "nodemon ./index.js"
}

And then run in powershell

npm run start-nodemon
