Adopting strong Git practices enables teams to collaborate efficiently, maintain code quality, and manage project changes with confidence.
- Define consistent workflows for branching and merging.
- Encourage regular reviews before integrating changes.
- Keep repositories organized and easy to maintain.
- Promote frequent synchronization with the shared codebase.
- Maintain clear version history for accountability and traceability.
1. Commits Should Be Small and Frequent
Frequent, small commits help maintain a clear project history, simplify code reviews, and make issues easier to track and fix.
- Commit one logical change at a time.
- Avoid large commits with extensive file or line changes.
2. Commit Messages are to Be Semantic
Clear commit messages explain the purpose of a change and make it easy to understand why code was added or modified.
- Avoid very short or vague messages (e.g., fewer than three words).
- Ensure messages provide enough detail to explain the change clearly.
3. Use of Branches
Using a Git branch helps organize related commits, supports pull requests, and keeps the main branch stable and production-ready.
- Group connected changes within a Git branch for easier review.
- Merge only finalized branch work into the main branch.
- Regularly run git pull to keep your Git branch up to date and reduce conflicts.
4. One Branch, One Feature
The feature branch strategy isolates new functionality in a dedicated branch, keeping the main branch stable and CI-ready.
- Create one Git branch per feature and integrate it using git merge.
- Keeps unfinished code out of the main branch.
- Simplifies code reviews by focusing on a single feature.
- Improves focus and readability through small, clear changes.
5. Handle Merge Properly
When multiple developers work on separate feature branches, conflicts can occur during a Git merge command if the same files are modified and require manual resolution.
- Conflicts arise when using Git commands like git merge on overlapping changes.
- Modern editors support Git commands with visual conflict resolution tools.
- Proper tooling makes resolving merge conflicts faster and more reliable.
6. Single Repository
Choosing between a single repository and multiple repositories depends on team size, product structure, and code ownership requirements.
- Small teams benefit from a single repository to keep code in sync and simplify refactoring.
- Shared internal libraries can be distributed via package managers.
- Multiple repositories are useful for separating closed-source code or client-specific work.
7. Avoid Committing Dependencies in Repo
A Git repository should track source code only, not external dependencies, to keep the project clean, lightweight, and maintainable.
- Avoid committing dependencies as they increase repository size
- Use appropriate build or dependency management tools instead of Git
- Choose tools based on the tech stack (e.g., Maven for Java, npm for Node.js)
- Helps ensure consistent dependency versions across all development environments.
8. Don't Commit Broken Code
Committing broken code can disrupt the entire team and block others from progressing, so code should always be tested before committing.
- Verify your changes locally before running git commit.
- Use git stash to temporarily save incomplete work when switching branches.
- Never commit code that breaks the build or functionality.
9. Use Tags
Git tags mark a specific snapshot of the codebase at release time, helping teams track versions and manage releases effectively.
- Tags capture a stable state of a branch without adding new commit history.
- Help track version numbers and compare changes between releases.
- Useful for documenting and maintaining clear release notes.
- Tags are immutable references to specific commits and do not behave like branches.
