Published on in Cool tools

Last updated on

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

npx: installed 1 in 1.085s
     172 text files.
     162 unique files.
      49 files ignored.
