Code review through pull requests maintains code quality, catches bugs early, shares knowledge across teams, and ensures consistent coding standards. As the creator of CoreUI, a widely used open-source UI library, I’ve reviewed thousands of pull requests in open-source projects throughout my 25 years of development experience. The most thorough approach is examining changes in GitHub’s review interface, testing locally when needed, and providing specific feedback. This method ensures code quality, identifies issues before merging, and fosters collaborative improvement through constructive discussion.
