- #Pre-Commit Hook
- Git pre-commit hook is a tool for automated quality assurance in software projects.
- Prevents commits if the script fails, stopping sensitive information from being tracked.
- Setting up requires placing a script in .git/hooks, but isn't version controlled by Git.
- Tools like Pre-Commit, Prek, and Husky simplify setup with dependency management.
- Pre-Commit supports common QA tools (Gitleaks, ESLint, Nixfmt) via manifests.
- Husky is npm-based, more suited for JavaScript/TypeScript projects.
- Symlinks can track hooks in Git, but setup is manual post-clone.
- Prevents secret leaks (API tokens, SSH keys) via tools like Gitleaks.
- Auto-formatting, linting, and testing can be integrated but may slow workflows.
- Reduces mental load by automating QA checks before code review.
- Can disrupt workflow if tests fail, leading developers to disable hooks.
- Requires setup post-clone, adding to onboarding complexity.
- Slow hooks annoy developers, especially with frequent small commits.
- Preventing secret leaks is the biggest benefit, worth the setup.
- Recommendation: Keep hooks fast and minimally disruptive.
- Devenv integrates Pre-Commit, simplifying setup and management.
- Alternatives include manual QA scripts, but they require user discipline.
