npm list only top level modules.

nl.sh

alias ng="npm list -g --depth=0 2>/dev/null"
alias nl="npm list --depth=0 2>/dev/null"

Thanks for this one, may I ask, what does the "/dev/null" do?

@Nilegfx that redirects stderr to /dev/null. See http://askubuntu.com/questions/350208/what-does-2-dev-null-mean

perfect nl is exactly the alias I had in mind

Just be careful, nl is also a "line numbering filter" utility. Not sure if you have it on your system, but it could cause problems if another script needs it. I'm using nlg nll.

These aliases are awesome but I just warn about possible conflict that may arise with https://github.com/angular/angular-cli [ng]((https://cli.angular.io/reference.pdf) and the ng alias.

This is awesome, exactly what I was looking for!

Thanks, based on this info I wrote a small bash script, usage can be
npl , npl 0 , npl 1 , npl 2 g, npl g , npl -h etc.
where 0,1,.. is the level and g is global, of course. Hope it helps someone.

(Don't forget to put it in a folder in your path and to chmod +x it.)

Note that options like --depth 0 can be set in npm's config as well.

So to make npm ls work more like *nix ls -l i.e. show only the top-level modules, you can run:

npm config set depth 0

Of course, you can always override this config setting from the command line, so to restore the original behaviour, i.e. make npm ls work more like *nix ls -lR, you can run:

npm ls -g --depth 9999

Note that setting depth in config also applies to npm la, npm ll, npm ls --long, etc., so no need to define shell aliases for any of those either.

Check this out npm ls -ps

This doesn't seem to work for node installed by nvm. I have to use --depth=1 to see the installed packages. Does anyone have a solution that works for both (or an easy way to detect whether the running npm is from nvm or not?

Why does the --depth option not appear in npm -h nor npm list -h ? Is this an hidden option?

Why does the --depth option not appear in npm -h nor npm list -h ? Is this an hidden option?

I tried looking for it too. I think it's just undocumented.
