We’re diving deep into the world of Git pre-commit hooks. Learn how these powerful tools can help streamline your development process by enforcing code quality and preventing mistakes right before you commit your changes.

We'll start with an overview of what pre-commit hooks are and how they can drastically improve the workflow for developers. You'll learn practical examples of implementing a pre-commit hook to prevent accidental commits to crucial branches such as ‘master’ or ‘main,’ making sure you only push your code to safe branches.

We’ll walk through the installation of the pre-commit package, creating a configuration file, and setting up a Python script to check which branch you’re currently on. We'll also explore an additional example that integrates GitHub repositories with tools like Black and Flake8 for automatic formatting and linting.

By the end of this video, you’ll have the knowledge to implement pre-commit hooks and countless other ways to improve your coding practices. Don’t forget to subscribe for more programming tips and tricks!
