# Git workflow commands and patterns
# === GitHub Flow ===
# 1. Create feature branch from main
git checkout main
git pull origin main
git checkout -b feature/add-user-auth
# 2. Make commits (conventional commits)
git add -A
git commit -m "feat(auth): add JWT authentication middleware"
git commit -m "feat(auth): add login and registration endpoints"
git commit -m "test(auth): add unit tests for auth middleware"
git commit -m "docs(auth): update API documentation"
# 3. Push and create PR
git push -u origin feature/add-user-auth
# Then create PR on GitHub/GitLab
# 4. After review, merge (squash on GitHub)
git checkout main
git pull origin main
git branch -d feature/add-user-auth
# === Useful Git commands ===
# Interactive rebase (clean up last 5 commits)
git rebase -i HEAD~5
# Squash commits
# In interactive rebase, change 'pick' to 'squash' or 's'
# Amend last commit
git commit --amend -m "feat(auth): updated message"
git commit --amend --no-edit # Keep message, add staged files
# Cherry-pick a commit to another branch
git checkout main
git cherry-pick abc1234
# Stash changes
git stash push -m "WIP: auth changes"
git stash list
git stash pop
git stash apply stash@{1}
# Find bug-introducing commit
git bisect start
git bisect bad HEAD
git bisect good v1.0.0
# Test each commit, then:
git bisect good # or git bisect bad
git bisect reset
# View pretty log
git log --oneline --graph --all --decorate
# Show changes in a commit
git show abc1234
# Blame (who changed what)
git blame src/auth.js
# Search commit messages
git log --grep="auth" --oneline
# Search code changes
git log -S "authenticate" --oneline
# Undo last commit (keep changes)
git reset --soft HEAD~1
# Undo last commit (discard changes)
git reset --hard HEAD~1
# Restore a file from another branch
git checkout main -- src/config.js
# Clean untracked files
git clean -fd # Remove untracked files and dirs
git clean -fdn # Dry run
# Tags for releases
git tag -a v1.2.0 -m "Release v1.2.0: Add auth module"
git push origin v1.2.0
git push origin --tags

Explain with highlit
Effective Git workflows enable smooth team collaboration. Git Flow uses main, develop, feature/*, release/*, and hotfix/* branches. GitHub Flow simplifies to main plus short-lived feature branches with pull requests. Trunk-based development commits directly to main with feature flags. Conventional commits (feat:, fix:, chore:) standardize messages for changelog generation. Protected branches require reviews and passing CI. Squash merging keeps history clean. Interactive rebase with git rebase -i cleans up commit history before merging. git bisect finds bug-introducing commits. Cherry-pick transfers specific commits between branches. Pre-commit hooks enforce linting and formatting. Semantic versioning tags mark releases.
