Branching Strategies
1. GitHub Flow (Recommended for Most Teams)
main (protected)
└── feature/add-user-auth
└── feature/payment-integration
└── fix/login-bug
Rules:
mainis always deployable- Create feature branches from
main - Open PR when ready for review
- Merge to
mainafter approval - Deploy immediately after merge
When to Use: Small teams, continuous deployment, web apps
2. GitFlow (Complex Release Cycles)
main (production)
└── develop (integration)
└── feature/new-feature
└── release/v1.2.0
└── hotfix/critical-bug
When to Use: Scheduled releases, multiple versions in production
3. Trunk-Based Development (High-Velocity Teams)
main (trunk)
└── short-lived feature branches (< 2 days)
When to Use: Experienced teams, strong CI/CD, feature flags
Branch Naming Conventions
# Feature branches
feature/user-authentication
feature/JIRA-123-payment-gateway
# Bug fixes
fix/login-redirect-loop
fix/JIRA-456-null-pointer
# Hotfixes (production emergencies)
hotfix/security-vulnerability
hotfix/v1.2.1-critical-fix
# Release branches
release/v1.2.0
release/2024-q1
# Experimental

spike/performance-testing
Commit Message Standards
Conventional Commits Format
<type>(<scope>): <subject>

Examples:
feat(auth): add OAuth2 Google login
Implement Google OAuth2 authentication flow with:
- Token refresh handling
- Profile sync on first login
- Session persistence
Closes #123

fix(api): prevent null pointer in user lookup
Check for undefined user before accessing properties.
Added defensive null checks throughout the auth flow.
Fixes #456
Common Git Operations
Rebasing vs Merging
# Rebase: Clean, linear history (use for feature branches)
git checkout feature/my-feature
git rebase main
git push --force-with-lease # Safe force push
# Merge: Preserves history (use for shared branches)
git checkout main
git merge --no-ff feature/my-feature
Interactive Rebase (Cleaning History)
# Squash last 3 commits
git rebase -i HEAD~3
# In editor:
pick abc1234 First commit
squash def5678 Second commit
squash ghi9012 Third commit
Stashing Work
# Save current changes
git stash push -m "WIP: user auth"
# List stashes
git stash list
# Apply and remove
git stash pop
# Apply specific stash
git stash apply stash@{2}
Cherry-Picking
# Apply specific commit to current branch
git cherry-pick abc1234
# Cherry-pick without committing
git cherry-pick --no-commit abc1234
Resolving Merge Conflicts
Step-by-Step Process
# 1. Start merge/rebase
git merge feature-branch
# CONFLICT message appears
# 2. Check status
git status
# Shows conflicted files
# 3. Open conflicted file, find markers:
<<<<<<< HEAD
current branch changes
=======
incoming branch changes
>>>>>>> feature-branch
# 4. Edit to resolve (remove markers, keep correct code)
# 5. Mark as resolved
git add <resolved-file>
# 6. Complete merge
git merge --continue
# or
git commit
Using Merge Tools
# Configure merge tool
git config --global merge.tool vscode
git config --global mergetool.vscode.cmd 'code --wait $MERGED'
# Launch merge tool
git mergetool
Undoing Changes
# Undo last commit, keep changes staged
git reset --soft HEAD~1
# Undo last commit, keep changes unstaged
git reset HEAD~1
# Undo last commit, discard changes (DANGEROUS)
git reset --hard HEAD~1
# Revert a commit (creates new commit)
git revert abc1234
# Discard all local changes
git checkout -- .
# Restore deleted file
git checkout HEAD~1 -- path/to/file
Pull Request Best Practices
Keep PRs Small
- Aim for < 400 lines changed
- Single responsibility
- Easier to review and revert
Write Good PR Descriptions
## Summary Brief description of changes ## Changes - Added user authentication - Updated database schema - Added unit tests ## Testing - [ ] Unit tests pass - [ ] Manual testing completed - [ ] No console errors ## Screenshots (if UI changes)Request Reviews Thoughtfully
- Tag relevant reviewers
- Provide context for complex changes
- Respond to feedback promptly
Git Aliases (Productivity)
# Add to ~/.gitconfig
[alias]
co = checkout
br = branch
ci = commit
st = status
unstage = reset HEAD --
last = log -1 HEAD
visual = !gitk
lg = log --oneline --graph --decorate
amend = commit --amend --no-edit
wip = !git add -A && git commit -m "WIP"
undo = reset HEAD~1 --mixed
Examples
User asks: "Set up Git workflow for my team"
Response approach:
- Ask about team size and release frequency
- Recommend appropriate branching strategy
- Establish branch naming conventions
- Set up commit message standards
- Configure branch protection rules
- Document PR review process
