What are Git hooks?
Git hooks are scripts that Git executes before or after events such as: commit, push, and receive. Git hooks are a built-in feature - no need to download anything. Git hooks are run locally.
These hook scripts are only limited by a developer's imagination. Some example hook scripts include:
- pre-commit: Check the commit message for spelling errors.
- pre-receive: Enforce project coding standards.
- post-commit: Email/SMS team members of a new commit.
- post-receive: Push the code to production.
How do they work?
Every Git repository has a
.git/hooks folder with a script for each hook you can bind to. You're free to change or update these scripts as necessary, and Git will execute them when those events occur.
Here's a full list of hooks you can attach scripts to:
Why should I care?
Fair question! Git hooks can greatly increase your productivity as a developer. Being able to push to your staging or production environment without ever leaving Git is just plain awesome. Update your code, make a commit and push, and your code can be running in any environment you specify. No need to mess with ssh or ftp.
How do I implement Git hooks?
The short and easy: Overwrite one of the scripts in
.git/hooks and make it executable.
