Git hooks
Slide 1 / 5Hooks are scripts Git runs automatically at certain moments. They live in .git/hooks/:
• pre-commit — before a commit is created: run a linter or formatter, block debug code. • commit-msg — check the message format. • pre-push — run tests before pushing.
A hook that exits with a non-zero status cancels the action. Hooks aren't shared through clones, so teams use tools like Husky or pre-commit to install them for everyone.
