Implementing a Husky Pre-Push Hook to Ensure Stability with Build Checks

When working on a codebase, ensuring stability before pushing changes is crucial. Bugs slipping into the main branch can cause significant disruptions. Fortunately, tools like Husky help mitigate these risks by allowing you to run scripts automatically at various stages of your Git workflow. In this post, we'll take a look at how to set up a Husky pre-push hook specifically to run your build commands, giving you peace of mind that your application remains intact on push.

The Problem: Ensuring Stability Before Pushing

You want to make sure that no failing builds or broken code gets pushed to your main branches. To achieve this, you can implement a Husky pre-push hook that runs specific commands before allowing any changes to be pushed to your repository.

Setting Up Your Husky Configuration

To set up Husky so that it runs yarn build before a push, you’ll need to modify the configuration within your project's package.json file. Here's the structure you should follow:

Explanation of the Code Configuration

Pre-Commit Hook: The pre-commit hook runs before every commit, and here, it uses lint-staged to lint your staged files, ensuring that no bad code makes it into your history.

Pre-Push Hook: The pre-push hook is your focus. The command cross-env lint-staged && yarn build accomplishes two things:

It runs lint-staged just like in the pre-commit step, ensuring all changes are linted.

It then runs yarn build, checking that your application builds successfully. If there are any issues during the build, the push will be aborted, keeping your main branch stable.

Chaining Multiple Commands

You may have noticed the use of && in the pre-push command. This operator allows you to chain multiple commands together, running them sequentially. If the first command fails, the second won't run. For example:

This type of chaining can be handy for combining numerous tasks into a single script to simplify your workflow.

Final Notes

While the setup seems straightforward, ensure that you test your hooks after making modifications. Run a commit and then a push to validate that both commands behave as expected and that any issues are caught effectively. If you're using yarn, make sure it's properly installed in your project, as the command yarn build relies on it.

With Husky in place, you'll have an added layer of security in your development workflow, helping maintain the integrity of your application as you collaborate with your team.

Conclusion

Integrating checks like yarn build into your Git workflow with Husky is an excellent practice to prevent broken code from being pushed to your repository. By following the configuration steps outlined above, you can ensure that your build passes every time you attempt to push new changes. Happy coding!
