Thanks! Looks like some normalize-path is needed for Windows support.

You should run the linters configured in the repo to make sure ESLint is happy, and also generate the changeset file to describe your change. It can be done with npx changeset and then type in your description.

I would treat this as a patch-level fix instead of a feature. 👍

This probably needs to be wrapped in normalizePath:

Suggested change

	return fs.realpath(defaultDir);
	return normalizePath(await fs.realpath(defaultDir))

On further testing, I'm closing this PR since we already support symlinks by using the fs.realPath here:

lint-staged/lib/resolveGitRepo.js

Line 18 in 4b9fb10

const defaultDir = normalizePath(await fs.realpath(path.join(gitDir, '.git')))
