How to setup lint-staged for Vue projects?

I created a new Vue3 app using the Vue CLI and selected Prettier for my linter config. I want to use commitlint, husky and lint-staged to validate commit messages and lint the code before pushing it.

What I did

Based on https://commitlint.js.org/#/guides-local-setup I setup commitlint with husky

npm install --save-dev @commitlint/{cli,config-conventional}
echo "module.exports = { extends: ['@commitlint/config-conventional'] };" > commitlint.config.js

npm install husky --save-dev
npx husky install
npx husky add .husky/commit-msg 'npx --no -- commitlint --edit $1'

Based on https://github.com/okonet/lint-staged#installation-and-setup I setup lint-staged

npx mrm@2 lint-staged

and inside the package.json I replace

"lint-staged": {
  "*.js": "eslint --cache --fix"
}

with

"lint-staged": {
  "*": "npm run lint"
}

The problem

When modifying the README.md file in the project to

# my-repo

---

new commit

and try to commit that I get the following error message

> git -c user.useConfigOnly=true commit --quiet --allow-empty-message --file -

What it should do

Only fix the files that have been modified. The linter knows about files it is able to fix (js, ts, vue, html, ...).

When having a modified markdown file I get no errors when opening the terminal and run npm run lint. But I do get errors when using lint-staged with this setup "*": "npm run lint"

What is the correct setup for lint-staged to lint "lintable" files only?
