Git is an essential tool for developer collaboration, but commands like merge and rebase frequently spark debates in engineering teams. Both commands serve the same fundamental purpose—integrating commits from one branch into another—but they do so in completely different ways. Understanding their differences is key to keeping your project's commit history clean and navigable.
When you run git merge, Git creates a new commit (a "merge commit") that ties the histories of the two branches together:
git checkout main
git merge feature-login- [object Object]
Rebasing shifts the base of your branch. It takes the commits you made on a feature branch and applies them sequentially on top of the target branch's latest commit:
git checkout feature-login
git rebase main- [object Object]
To avoid disrupting your team's workflow, adhere to the golden rule of rebasing: **Never rebase a branch that is shared publicly or has been pushed to a remote repository.**
- [object Object]
Interactive rebasing (git rebase -i) is a powerful tool to tidy up your commits before submitting a pull request. It allows you to:
- [object Object]
Choosing between merge and rebase depends on your team's workflow preferences. Merging is safer and preserves historical context, while rebasing keeps histories clean and linear. Combining both methods—rebasing local branches to clean up commits, and merging them into the main branch—gives you the best of both worlds.
