Run npx cloc [options] <files/dirs>. E.g. npx cloc src/ or npx cloc foo.js bar.css.

The cloc npm package by Kent C. Dodds is a wrapper around the cloc command line program by Al Danial.

Example from this repo:

$ npx cloc . \
    --exclude-dir=_sample-content,_site,node_modules \
    --not-match-f=package-lock.json
