Mastering Code Reviews (There's More!)
The code review is a fundamental ritual in modern software development. It's the moment where a solitary act of coding becomes a collaborative act of engineering.
For this process to be truly effective, both the developer submitting the code and the reviewer scrutinizing it must operate with shared principles. These principles were mandatory reading for all of us at Google. (Btw if you're interested in an experienced engineer's surprise at the sheer level of tooling and infra at Google read this post!)
Unlike the previous post which was target at junior devs, this guide is for both sides of the pull request.
We will first explore how a developer can submit code that builds trust and earns respect. That's Part 1.
Then in Part 2, further below, we will look at how a reviewer can provide feedback that elevates the codebase and mentors their team.
Part I: The Developer's Playbook for Submitting Code
Your pull request (PR) is more than just a code drop; itā€™s a signal. It tells your team about your discipline, your attention to detail, and your engineering maturity. A well-crafted PR builds trust and streamlines the entire process.
1. Your Description Is Your Calling Card
Don't just say "fixed bug." Your description is your narrative. It will live on in the commit history forever.
