How to list npm user-installed packages?

How do I list the user-installed / environment package only in npm?

When I do npm -g list, it outputs every package and their dependencies. Instead I'd like to see the packages installed in the current working project or environment.

npm list -g --depth=0

• npm: the Node.js 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
