Git Branching Strategies Part 2: Best Practices and Implementation

Hello there!👋🧔‍♂️ Welcome back to Part 2 of our Git Branching Strategies series! In Part 1, we explored the five popular branching strategies: Git Flow, GitHub Flow, GitLab Flow, Trunk-Based Development, and Feature Branch Workflow.

Now that you understand the different strategies, let's dive into best practices and implementation details. Whether you've chosen a strategy or are still deciding, these practices will help you implement any workflow effectively.

Overview

In this part, we'll explore:

1. Best Practices for Any Strategy - Universal guidelines that apply to all workflows
2. Using Ticket IDs for Traceability - Linking code to requirements and discussions
3. Commit Message Best Practices - Writing clear, meaningful commit messages
4. Branch Naming Conventions - Consistent naming standards
5. Anti-Patterns to Avoid - Common mistakes and how to prevent them
6. Real-World Examples - Practical implementations
7. Migrating Between Strategies - How to evolve your workflow

Let's start with best practices that work regardless of which strategy you choose!

Best Practices for Any Strategy

General Best Practices

✅ Use descriptive branch names - feature/user-authentication not feature/branch1
✅ Include ticket IDs - Link branches and commits to tickets (e.g., feature/PROJ-123-user-auth)
✅ Keep branches small - One feature or fix per branch
✅ Commit often - Small, frequent commits with clear messages
✅ Write good commit messages - Explain what and why, include ticket ID if applicable
✅ Use Pull/Merge Requests - Always review code before merging
✅ Keep main stable - Main should always be deployable
✅ Delete merged branches - Clean up after merging
✅ Use tags for releases - Tag important releases
✅ Document your strategy - Make sure team understands the workflow

Using Ticket IDs for Traceability

Why use Ticket IDs?

Linking your code to tickets (JIRA, GitHub Issues, Azure DevOps, etc.) provides:

• Traceability - Link code changes to requirements and discussions
• Context - Quick access to ticket details, acceptance criteria, and related conversations
• Reporting - Track which tickets are completed, code coverage per ticket
• Code Review - Reviewers can quickly understand the business context
• Documentation - Self-documenting code history

Best Practices:

• Include ticket ID in branch names
• Include ticket ID in commit messages
• Use consistent ticket ID format (e.g., PROJ-123, GH-456, #789)
• Make ticket IDs clickable in your Git hosting platform

Ticket ID Formats by Platform

JIRA:

• Format: PROJ-123
• Example: feature/PROJ-123-user-authentication

GitHub Issues:

• Format: GH-456 or #456
• Example: feature/GH-456-add-dark-mode

Azure DevOps:

• Format: AB#123 or 123
• Example: feature/AB-123-payment-integration

Linear:

• Format: LIN-789
• Example: bugfix/LIN-789-login-error

Commit Message Best Practices

Good commit messages are essential for understanding code history. They should explain what changed and why it changed.

Commit Message Structure

# Format: [Ticket ID]: [Type] [Description]

# Examples with ticket IDs
git commit -m "PROJ-123: Add user authentication with JWT tokens"
git commit -m "PROJ-456: Fix memory leak in image processing service"
git commit -m "PROJ-789: Refactor payment service to use dependency injection"

# Examples without ticket IDs (if not using tickets)
git commit -m "Add user authentication with JWT tokens"
git commit -m "Fix memory leak in image processing service"
git commit -m "Refactor payment service to use dependency injection"

Multi-Line Commit Messages

For complex changes, use multi-line commit messages:

git commit -m "PROJ-123: Add user authentication with JWT tokens

- Implement JWT token generation
- Add token validation middleware
- Update user model with authentication fields
- Add unit tests for authentication flow

Closes PROJ-123"

Commit Message Types

Use conventional commit types for consistency:

• feat: - New feature
• fix: - Bug fix
• docs: - Documentation changes
• style: - Code style changes (formatting, etc.)
• refactor: - Code refactoring
• test: - Adding or updating tests
• chore: - Maintenance tasks

Examples:

git commit -m "PROJ-123: feat: Add user authentication"
git commit -m "PROJ-456: fix: Resolve memory leak in image processing"
git commit -m "PROJ-789: refactor: Extract payment logic to service"

Bad Commit Messages

❌ Avoid vague messages:

git commit -m "fix"
git commit -m "update"
git commit -m "changes"
git commit -m "WIP"

✅ Use descriptive messages:

git commit -m "PROJ-456: Fix memory leak in image processing service"
git commit -m "PROJ-789: Update payment gateway integration"
git commit -m "PROJ-123: Add user authentication feature"

Branch Naming Conventions

Consistent branch naming makes it easy to understand what each branch contains and how it relates to your workflow.

Branch Naming Format

With Ticket IDs:

• Format: {type}/{ticket-id}-{short-description}
• Examples: feature/PROJ-123-user-auth, bugfix/GH-456-login-fix

Without Ticket IDs:

• Format: {type}/{short-description}
• Examples: feature/user-authentication, bugfix/login-error

Branch Types

# Feature branches (with ticket IDs)
feature/PROJ-123-user-authentication
feature/PROJ-456-payment-integration
feature/GH-789-add-dark-mode

# Feature branches (without ticket IDs)
feature/user-authentication
feature/payment-integration
feature/add-dark-mode

# Bug fixes (with ticket IDs)
bugfix/PROJ-234-login-error
bugfix/PROJ-567-memory-leak
fix/PROJ-890-payment-gateway-timeout

# Bug fixes (without ticket IDs)
bugfix/login-error
bugfix/memory-leak
fix/payment-gateway-timeout

# Hotfixes (with ticket IDs)
hotfix/PROJ-111-critical-security-fix
hotfix/PROJ-222-database-connection-issue

# Hotfixes (without ticket IDs)
hotfix/critical-security-fix
hotfix/database-connection-issue

# Releases
release/1.2.0
release/v2.0.0

Branch Naming Guidelines

• Keep descriptions short - 2-4 words maximum
• Use hyphens - Separate words with hyphens, not underscores
• Use lowercase - Keep branch names lowercase for consistency
• Be descriptive - Name should clearly indicate what the branch contains
• Include ticket ID - If using tickets, always include the ticket ID

Examples:

# ✅ Good
feature/PROJ-123-user-auth
bugfix/PROJ-456-login-error
hotfix/PROJ-789-security-patch

# ❌ Bad
feature/branch1
bugfix/fix
hotfix/urgent
feature/user_authentication  # Use hyphens, not underscores
feature/UserAuthentication   # Use lowercase

Anti-Patterns to Avoid

Common Mistakes

❌ Long-lived feature branches - Merge quickly, don't let branches live for weeks
❌ Merging broken code - Never merge code that breaks tests
❌ Skipping code review - Always review before merging
❌ Committing directly to main - Use branches for all changes
❌ Ignoring conflicts - Resolve merge conflicts properly
❌ Forgetting to pull - Always pull latest changes before starting work
❌ Large commits - Break work into smaller commits
❌ Vague commit messages - Be specific about what changed
❌ Missing ticket IDs - If using tickets, always include ticket ID in branch names and commits
❌ Inconsistent ticket ID format - Use consistent format across the team (e.g., always PROJ-123 not proj-123 or PROJ123)

How to Avoid These Mistakes

1. Keep Branches Short-Lived

# ✅ Good: Merge within days
git checkout -b feature/PROJ-123-small-feature
# ... work for 1-2 days ...
git merge feature/PROJ-123-small-feature

# ❌ Bad: Branch lives for weeks
git checkout -b feature/PROJ-123-large-feature
# ... work for 3 weeks ...
git merge feature/PROJ-123-large-feature

2. Always Test Before Merging

# ✅ Good: Run tests before merging
npm test
git push origin feature/PROJ-123-feature

# ❌ Bad: Merge broken code
git push origin feature/PROJ-123-feature  # Tests failing!

3. Use Pull Requests

# ✅ Good: Create PR for review
git push origin feature/PROJ-123-feature
# Create Pull Request, get approval, then merge

# ❌ Bad: Merge directly without review
git checkout main
git merge feature/PROJ-123-feature  # No review!

Real-World Example: E-Commerce Project

Let's see how a team might use GitHub Flow for an e-commerce project with ticket IDs:

# Developer starts new feature (ticket PROJ-123)
git checkout main
git pull origin main
git checkout -b feature/PROJ-123-shopping-cart

# Work on feature (each commit references the ticket)
git add .
git commit -m "PROJ-123: Add add-to-cart functionality"
git commit -m "PROJ-123: Add remove-from-cart functionality"
git commit -m "PROJ-123: Add cart persistence to localStorage"
git push origin feature/PROJ-123-shopping-cart

# Create Pull Request on GitHub
# PR title: "PROJ-123: Implement shopping cart functionality"
# PR description: "Implements shopping cart feature as per PROJ-123 requirements..."
# Team reviews, approves, merges
# Auto-deploys to production

# After merge
git checkout main
git pull origin main
git branch -d feature/PROJ-123-shopping-cart

Benefits of using ticket IDs:

• Pull Request automatically links to ticket PROJ-123
• Commit history shows all changes related to the ticket
• Easy to find all code changes for a specific requirement
• Ticket can reference the PR and commits for full traceability

Example: Multiple Commits for One Feature

# Feature branch with multiple commits
git checkout -b feature/PROJ-123-user-profile

# Commit 1: Database schema
git add db/migrations/
git commit -m "PROJ-123: Add user profile database schema"

# Commit 2: API endpoint
git add api/users/
git commit -m "PROJ-123: Add user profile API endpoint"

# Commit 3: Frontend component
git add components/UserProfile/
git commit -m "PROJ-123: Add user profile frontend component"

# Commit 4: Tests
git add tests/
git commit -m "PROJ-123: Add user profile tests"

# Push and create PR
git push origin feature/PROJ-123-user-profile

Migrating Between Strategies

Sometimes your needs change, and you need to evolve your branching strategy. Here's how to migrate between strategies:

From Git Flow to GitHub Flow

If you want to simplify:

1. Stop creating release branches - Merge directly to main
2. Merge develop into main - Consolidate branches
3. Update CI/CD - Deploy from main
4. Train team - Update documentation and workflows

Migration Steps:

# 1. Finish all release branches
git checkout release/1.2.0
# Complete release, merge to main

# 2. Merge develop into main
git checkout main
git merge develop
git push origin main

# 3. Update CI/CD to deploy from main
# Update deployment scripts/config

# 4. Update team documentation
# Document new workflow

From Feature Branch to Trunk-Based

If you want faster integration:

1. Start committing small changes directly - Build confidence
2. Use feature flags - For incomplete features
3. Shorten branch lifetimes - Merge within days
4. Strengthen tests - Ensure main stays stable

Migration Steps:

# 1. Start with small, safe changes
git checkout main
git pull origin main
# Make small change
git commit -m "Fix typo in README"
git push origin main

# 2. Gradually increase direct commits
# As team gains confidence, commit more directly

# 3. Use feature flags for incomplete features
# Wrap incomplete features in feature flags

# 4. Strengthen CI/CD pipeline
# Ensure all tests pass before merge

From GitHub Flow to Git Flow

If you need more structure:

1. Create develop branch - New integration branch
2. Update workflows - Features merge to develop first
3. Add release branches - For release preparation
4. Train team - Update documentation

Migration Steps:

# 1. Create develop branch
git checkout main
git checkout -b develop
git push origin develop

# 2. Update workflows
# Features now merge to develop first
# Releases branch from develop

# 3. Update CI/CD
# Deploy develop to staging
# Deploy main to production

# 4. Update team documentation
# Document new workflow
