Hello @kartik,
This works pretty well too: 
npm list -g --depth=0
- npm: the Node package manager command line tool
 
- list -g: display a tree of every package found in the user’s folders (without the -g option it only shows the current directory’s packages)
 
- depth 0 / — depth=0: avoid including every package’s dependencies in the tree view
 
Hope it helps!!
Thank you!!
