Step-1

type npm init in terminal for package.json

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help init` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Step -2

Press Enter

package name: (crud-rest-api-using-node)

version: (1.0.0)
description:
entry point: (index.js) app.js
test command:
git repository:

Step - 3

do npm i express

or npm install express

we got a dependencies express

Step - 4

npm install mongodb

Step - 5

npm install mongoose

Step - 6

install nodemon

for restarting the server automatically whenever we do changes in code and save it

so that we don't need to start the server again and again

type npm install nodemon

but it will install in dependencies

but we don't want to install in dependencies because jb hm project ko deploy krenge toh saari dependencies production server me jate hai

server me all dependencies download ho jayengi

but hm nodemon ko nhi bhejna chahte production server pe because iski need only development ke time hai

TO OVERCOME THIS PROBLEM

nodemon ko different dependencies me install krenge

so type

npm install nodemon --save-dev

dev means development environment

NOW NODEMON INSTALLED IN SEPARATE DEPENDENCIES

THAT IS =>

 "devDependencies": {
    "nodemon": "^2.0.20"
  }

Step - 7

package.json me scripts me "start": "nodemon app.js" likho

Earlier

 "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

After editing scripts

"scripts": {
 "start": "nodemon app.js"
},

Last Step

create app.js and do coding in it
