A visual breakdown of how modern git hook managers intercept your commits — and how I built one in pure Dart.
How Git Hook Managers Work — An Eagle's View
Every git repository ships with a hidden superpower: .git/hooks/. Drop an executable shell script in there, and Git runs it automatically before commits, pushes, and merges.
The problem? That folder isn't version controlled. Your teammates get nothing.
That's the only problem a git hook manager solves.
Tools like husky, lefthook, and dart_husky all follow the same architecture:
A config file (YAML) defines what to run and when. A parser reads it and a model turns it into typed objects. The CLI wires it together — the installer writes tiny delegation scripts into .git/hooks/, and the runner executes the actual commands when Git fires. For commit messages, a validator checks against the conventional commits spec.
When you run git commit, Git finds the script, calls the runner, commands execute, and any failure blocks the commit. That's the whole thing.
No daemons. No background processes. Just a shell script and a Dart binary.
dart_husky is open source and available on pub.dev. If you're building Dart or Flutter apps, give it a try — and if you find it useful, a ⭐ on GitHub goes a long way.
