If you are only interested in the packages installed globally without the full TREE then   npm -g ls --depth 0  or locally  omit -g     npm ls --depth 0

Generally  there are two ways to list out installed packages - through the Command Line Interface  CLI  or in your application using the API   Both commands will print to stdout all the versions of packages that are installed  as well as their dependencies  in a tree-structure     CLI  npm list   Use the -g  global  flag to list out all globally-installed packages  Use the --depth 0 flag to list out only the top packages and not their dependencies     API  In your case  you want to run this within your script  so you d need to use the API  From the docs   npm commands ls args   silent   callback    In addition to printing to stdout  the data will also be passed into the callback

Why not grab them from dependencies in package json   Of course  this will only give you the ones you actually saved  but you should be doing that anyway   console log Object keys require    package json   dependencies
