Practical Git: Run scripts on git events with git hooks


Git lets us run scripts on git events like pre-commit, pre-rebase, post-commit, post-merge, post-checkout, etc. You can do this by adding an executable file to the ./git/hooks directory which has a name matching the git hook name. In this lesson, we walk through this process by setting up a pre-commit hook which runs our npm test and npm run lint npm scripts to ensure we don't have any failing tests or lint errors before committing.
