What NPM does ?

Introduction#

It allows you to easily manage different packages (modules) and keep track of which version you’ve installed.

Initialize a new NPM project

npm init

This will initialize a new NPM project for you - just press enter until it stops asking you questions.

Now you’ll notice that you have a new file called package.json. This file will, among other things, keep track of which packages or modules you’ve installed in your project.
