Git hooks are scripts that Git runs before or after certain events like committing, pushing, or merging code. They can be used to enforce rules and automate tasks, making sure code quality, security, and backup processes are maintained consistently across the team.
Pre-commit hooks run before a commit is finalized, allowing us to inspect the code and abort the commit if necessary. This ensures that sensitive information is not accidentally included in the commit.
Why manually write these hooks instead of using tools like GitLeaks or GitGuardian? While tools provide advanced secret-scanning, manually writing hooks gives us complete control over our logic and scope, tailored specifically to our team's workflows.
Let us go over requirements that we would try to meet. Recently I was working on a project where I was going to check into GitHub and it had sensitive database connections and other settings, necessitating careful validation prior to committing.
