The **validate‑commit‑message** package provides a Git `commit‑msg` hook that automatically checks each commit against the AngularJS commit‑message conventions. By installing the npm module and running its init script, developers get a symbolic link in `.git/hooks/commit‑msg` that runs `lib/validate‑commit‑msg.js` on every commit, ensuring consistent, properly formatted commit messages for any Node‑based project. It’s aimed at developers who want to enforce a standard commit style across their Git repositories.
