As suggested in #11

Thanks @hlolli this looks great!

Just about to head to a family get together for the weekend but will review this when I'm back next week.

I did take a quick peek, this is great as-is, but bonus points for checking globally installed binaries too.

I was mostly having problems with falling back to default completions on a new argument field, already stopped the completions on arguments after the 2nd one (the executable), but then I just get no completions at all, would like to get the filesystem completions. Going to look at this when I have time, busy days atm.. The bonus point should be easy to earn, tough generally, it's a bad practice to npx something which isn't declared in a package (and I think package-local executeables have precedence). I guess people use it when they don't add the global npm .bin directory to their path (which also sounds like a bad practice, but I tend to do that).

Since apparently this isn't maintained anymore, I have simply started using @hlolli 's fork. Instructions for anyone else:

As an Oh My ZSH! custom plugin

Clone zsh-better-npm-completion into your custom plugins repo

git clone https://github.com/hlolli/zsh-better-npm-completion ~/.oh-my-zsh/custom/plugins/zsh-better-npm-completion

Then load as a plugin in your .zshrc

plugins+=(zsh-better-npm-completion)
