Today was my first session in Lint-School, we talked about Git and why it is so important in the life of developers.

We talked about how important Gitflow is and why it could save you countless hours of solving merge conflicts, as well as making your Pull Requests short

if you want to know more about GitFlow, I'd recommend this tutorial.

we also learned that PRs (pull requests) are not just for show, they help maintain trust between team members, another eye for catching bugs, forcing discussions and set coding guidelines.

But that's not enough. when a PR is long, people tend to skim it over and give you an "over-the-surface" review

So a golden rule of thumb is to make sure your PR is a work of a day or less if it takes more than a day, u should break it down to a couple of PRs.

This starts from the way you start working on a certain feature, you need to read the feature, make sure you understand it correctly and start breaking it down to smaller features, each feature with their own branch and their respective PR

this way we get better code reviews, and less "looks fine."

We also talked about the importance of CI/CD workflow in your work with Git CI/CD is a productivity beast that takes too little time to deploy and its gains are tremendous

Coming from an iOS background, when deploying builds to testers and to the store, we go through a process called archiving, it's a long process and usually produces a big file which you have to upload, with a bad internet, this process becomes tedious, also the fact that you have to constantly produce a build to testers so they can test is a pain.

By setting up CI/CD you solve such problems by setting configurations to each pipeline, for example in Git-flow we have 5 pipelines, Master-Develop-Feature-Release-Hotfix

each pipeline should do something when an event happens from the perspective of CI/CD an event is on push, merge, pull request

for example, when a pull request is opened to the develop from a feature branch, build the project and make sure tests run, if not, deny merge if a merge occurs on the release, push a build to testers

Conclusion

Git is an essential tool that any developer has to learn, but learning it alone is not enough for big teams, Git-Flow helps in enhancing the process of version control, even better is applying the CI/CD to your workflow, those are the three levels of any git user
