Git Hooks: Automate Your Workflow and Enforce Quality

Introduction

Git hooks are scripts that run automatically at specific points in your Git workflow, such as before a commit or before a push. They provide a powerful way to automate tasks, enforce coding standards, and ensure code quality before changes are shared with your team.

In this Blueprint, we utilize Husky to manage Git hooks and CommitLint to enforce consistent commit message formatting.

Husky: Simplifying Git Hooks Management

Husky is a tool that makes it easy to set up and manage Git hooks in your project. It simplifies the process of defining and executing scripts at various Git events.

How Husky Works

  • Husky leverages npm scripts defined in your package.json file to trigger actions at specific Git hooks.
  • It automatically installs and configures the necessary Git hooks in your project's .git/hooks directory.
  • Husky provides a clear and concise way to define which scripts should run at each hook.

CommitLint: Enforcing Commit Message Standards

CommitLint helps you maintain clean and informative commit messages by enforcing a set of rules and conventions. Consistent commit messages make it easier to understand the history of your project and facilitate collaboration within your team.

How CommitLint Works

  • CommitLint analyzes your commit messages against a predefined set of rules.
  • It provides feedback on any violations, helping you craft clear and meaningful commit messages.
  • CommitLint can be integrated into your Git hooks to prevent commits with non-compliant messages.

Integrating Git Hooks in Your Project

  1. Husky Setup:
    • Husky should already be installed and configured if you followed the Blueprint setup.
    • If you need to set it up manually, refer to the Husky documentation.
  2. CommitLint Configuration:
    • The commitlint.config.js file in your project root defines the rules for your commit messages.
    • You can customize these rules to match your team's preferences and conventions
  3. Git Hooks Configuration:
    • The tools/git-hooks-ddev/hooks directory contains the scripts that will be executed at specific Git events
    • The pre-commit hook is configured to run pnpm lint-staged, which, in turn, executes the scripts defined in the lint-staged section of your package.json.
    • The commit-msg hook is configured to run CommitLint to validate your commit messages

Conclusion

Git hooks, powered by Husky and CommitLint, are essential for automating your workflow and enforcing code quality and consistency. By integrating these tools into your project, you can streamline your development process, improve collaboration, and maintain a clean and organized Git history
