Ignore multiple directories in git hook

Question

I want to ignore any dist and node_modules directories in my git commit hook. I've tried this:

git diff --cached --name-only --diff-filter=ACM | find . -path ./node_modules -prune -o -path './**/dist -prune -o -name '*.js'

But it doesn't work. It doesn't seem like the find is accepting the files found from the git diff...

If I run:

git diff --cached --name-only --diff-filter=ACM

I correctly get the staged files:

./dist/some-file.js

And if I run:

find . -path ./node_modules -prune -o -path './**/dist' -prune -o -name '*.js' -print

I correctly get a list of files that don't include any that are in dist or node_modules directories.

How can I combine these do that my git hook doesn't pick up staged files in dist directories.

find doesn't process its standard input, so it can't be used after |

grep can be used instead

| grep -v '/dist/' | grep -v '/node_modules/'

or using one grep process

| grep -Ev '/dist/|/node_modules/'
