I work alone on my programming projects, but I still make pull requests. I also review my PRs. It feels silly hitting the Approve button in BitBucket, and BitBucket knows that. It keeps warning me that my PR doesn’t have any external reviewers.
In 2003, the first year of this blog, I wrote about using Source Control for One, where I agreed with Eric Sink that source control was useful when working alone. It’s hard to think that there was a time when that would be non-obvious advice, but it wasn’t.
Today, in 2023, I think making PRs when working alone is probably common. I think that reviewing them isn’t. I’m not sure if I can convince you, but the reason I do it is that I keep finding problems. Also, it keeps me honest and makes sure that I keep Constructing PRs to Make Reviewing Easy.
