Thanks for the MR!
There is some changes needed, and some tests:

• in https://github.com/pure-fish/pure/pull/tests/_pure.test.fish (for default values) ;
• and a new tests/_pure_prompt_npmrc.test.fish (for the feature);

You can check https://github.com/pure-fish/pure/blob/master/tests/_pure_prompt_virtualenv.test.fish for example, then run the tests with

❯ make test-pure-on FISH_VERSION=3.6.1 CMD='fishtape tests/_pure_prompt_npmrc.test.fish'

readlink has no output when $HOME/.npmrc is a regular file and not a symlink. You don't need to resolve the link just to show the basename.

Suggested change

	set npmrc (readlink $HOME/.npmrc | cut -d '/' -f 5)
	set npmrc (basename $HOME/.npmrc)
