Atomic Commits

Atomic Commits

Organize multiple git changes into clean, atomic commits that maintain a proper git history.

Workflow

1. Analyze Changes

git status
git diff --stat
git diff

2. Group Changes Logically

Categorize by type:

• feat: New features
• fix: Bug fixes
• refactor: Code improvements
• docs: Documentation
• test: Test changes
• chore: Maintenance

3. Commit Incrementally

Stage specific files for each logical commit:

git add path/to/related/files
git commit -m "feat: add user authentication"

git add path/to/other/files
git commit -m "fix: correct null check in validator"

4. Push

git log --oneline -10  # Verify commits
git push origin <branch>

Commit Order

1. Documentation (lowest risk)
2. Tests (verification setup)
3. Bug fixes (independent corrections)
4. Features (main changes)
5. Refactoring (improvements)

Commit Message Format

<type>(<scope>): <description>

[optional body]

Types: feat, fix, docs, style, refactor, test, chore

Example

Given changes to login page, avatar fix, README update, and new tests:

git add README.md
git commit -m "docs: update README with login instructions"

git add tests/login.test.ts
git commit -m "test: add login component tests"

git add src/components/Avatar.tsx
git commit -m "fix: correct avatar display on retina screens"

git add src/pages/Login.tsx src/components/LoginForm.tsx
git commit -m "feat: add login page with validation"

git push origin feature/login

Tips

• Each commit should be independently reviewable
• Each commit should leave codebase in working state
• When in doubt, prefer more commits over fewer
• Use git add -p for interactive staging of partial files
