| Type | Description | Example |
|---|---|---|
feat | New feature | feat(auth): add OAuth2 login |
fix | Bug fix | fix(api): handle null response |
docs | Documentation | docs(readme): update setup steps |
style | Formatting | style: fix indentation |
refactor | Code restructuring | refactor(db): simplify query builder |

BAD:
- "fix"
- "update code"
- "WIP"
- "changes"
- "asdfasdf"
GOOD:
- "fix(auth): prevent session timeout on idle"
- "feat(cart): add quantity validation"
- "refactor(api): extract common error handling"
fix(payment): prevent double charge on retry
The payment gateway timeout was causing the retry logic to submit
duplicate charges. Added idempotency key to prevent double-processing.

# Start new feature
git checkout main
git pull origin main
git checkout -b feature/AUTH-123-add-login
# Work on feature
git add -p # Stage hunks interactively
git commit -m "feat(auth): add login form"
# Keep up to date
git fetch origin
git rebase origin/main # Preferred: clean history
# OR
git merge origin/main # Alternative: preserves context
# Push and create PR
git push -u origin feature/AUTH-123-add-login
| Command | Purpose |
|---|---|
git stash | Save uncommitted changes temporarily |
git stash pop | Restore stashed changes |
git commit --amend | Modify last commit |
git rebase -i HEAD~3 | Interactive rebase (squash, reorder) |
git cherry-pick <sha> | Apply specific commit |
git bisect | Binary search for bug introduction |
git reflog | View all HEAD movements (recovery) |
# Delete merged branches locally
git branch --merged | grep -v main | xargs git branch -d
# Prune remote tracking branches
git fetch --prune
# Clean untracked files (careful!)
git clean -fd
1. Identify conflicts
git status
2. Open conflicted files
<<<<<<< HEAD
your changes
=======
their changes
>>>>>>> feature-branch
3. Resolve (keep one, combine, or rewrite)
4. Mark resolved
git add <resolved-file>
5. Continue
git rebase --continue # if rebasing
git commit # if merging

| Problem | Solution |
|---|---|
| Accidental commit to main | git reset HEAD~1 (before push) |
| Wrong branch | git stash, switch, git stash pop |
| Need to undo merge | git revert -m 1 <merge-commit> |
| Lost commits | git reflog to find, git cherry-pick |
| Large file committed | git filter-branch or BFG Repo-Cleaner |
# Undo last commit (keep changes)
git reset --soft HEAD~1
# Undo last commit (discard changes)
git reset --hard HEAD~1
# Recover deleted branch
git reflog
git checkout -b recovered-branch <sha>
# Undo a pushed commit (safe)
git revert <sha>
