In a fast-paced world, more teams have microservices architectures and are making the shift to Continuous Deployment and Trunk-Based Development. For one of our client’s teams, that meant no feature branches, pairs always committing to main, pushing frequently (multiple times per hour, as often as every 1–4 commits) and those changes landing in production 20–30 minutes later.
With pair programming, no feature branches, and such continuous change, code reviews would seem redundant or extremely difficult with little in the way of tooling support. How on earth would you use GitHub’s Pull Request review features in this setting when there’s no feature branch to diff?
