🔄 Development Workflow

Branch Strategy

We use Git Flow with the following branch structure:

• main - Production-ready code
• develop - Integration branch for features
• feature/* - New features
• bugfix/* - Bug fixes
• hotfix/* - Production hotfixes
• release/* - Release preparation

Branch Naming Conventions

feature/user-authentication
feature/inventory-low-stock-alerts
bugfix/order-status-update
hotfix/security-jwt-validation
release/v1.0.0

Workflow Steps

1. Start New Feature

# Create feature branch from develop
git checkout develop
git pull origin develop
git checkout -b feature/your-feature-name

# Make changes and commit
git add .
git commit -m "feat: add user registration endpoint"

# Push to remote
git push origin feature/your-feature-name

2. Create Pull Request

PR Template:

## Description
Brief description of changes

## Type of Change
- [ ] New feature
- [ ] Bug fix
- [ ] Breaking change
- [ ] Documentation update

## Testing
- [ ] Unit tests added/updated
- [ ] Integration tests pass
- [ ] E2E tests pass
- [ ] Manual testing completed

## Checklist
- [ ] Code follows project coding standards
- [ ] Self-review completed
- [ ] Comments added for complex logic
- [ ] Documentation updated
- [ ] No console.log or debug code
- [ ] Dependencies are up to date

3. Code Review Requirements

• Minimum 1 approval required
• All CI checks must pass:
  • Backend tests (70%+ coverage)
  • Frontend tests (70%+ coverage)
  • Linting passes
  • Build succeeds
• No merge conflicts
• Branch up to date with base branch

4. Merge Process

# Update feature branch with latest develop
git checkout develop
git pull origin develop
git checkout feature/your-feature-name
git rebase develop

# Squash commits if needed
git rebase -i HEAD~3

# Push (force if rebased)
git push origin feature/your-feature-name --force-with-lease

After approval, use Squash and Merge to keep history clean.

📝 Commit Message Convention

We follow Conventional Commits:

<type>(<scope>): <subject>

<body>

<footer>

Types

• feat: New feature
• fix: Bug fix
• docs: Documentation changes
• style: Code style changes (formatting)
• refactor: Code refactoring
• test: Adding or updating tests
• chore: Maintenance tasks
• perf: Performance improvements
• ci: CI/CD changes

Examples

feat(auth): add JWT refresh token endpoint

Implements refresh token functionality to extend user sessions
without requiring re-authentication.

Closes #123

---

fix(inventory): correct stock calculation for concurrent updates

Use pessimistic locking to prevent race conditions when multiple
users adjust stock simultaneously.

Resolves #456

---

docs(api): add GraphQL schema documentation

Add inline documentation for all GraphQL types and queries.

🧪 Testing Requirements

Before Committing

# Backend tests
dotnet test

# Frontend tests
cd frontend && npm test

# Linting
cd frontend && npm run lint

Pre-commit Hook (recommended)

Create .git/hooks/pre-commit:

#!/bin/sh

echo "Running pre-commit checks..."

# Run backend tests
dotnet test --no-build --verbosity quiet
if [ $? -ne 0 ]; then
    echo "❌ Backend tests failed"
    exit 1
fi

# Run frontend tests
cd frontend && npm test -- --run
if [ $? -ne 0 ]; then
    echo "❌ Frontend tests failed"
    exit 1
fi

echo "✅ All checks passed"
exit 0

🔍 Code Review Guidelines

What to Look For

Architecture

• Follows microservices patterns
• Proper separation of concerns
• Appropriate use of design patterns

Code Quality

• Readable and maintainable
• No code duplication
• Proper error handling
• Appropriate logging

Security

• No hardcoded secrets
• Input validation
• Authentication/authorization checks
• SQL injection prevention

Performance

• No N+1 queries
• Proper indexing
• Caching where appropriate
• Async operations used correctly

Testing

• Adequate test coverage
• Tests are meaningful
• Edge cases covered
• Integration tests for critical paths

Providing Feedback

Good Feedback:

❌ "This code is bad"
✅ "Consider extracting this logic into a separate service to improve testability and follow SRP"

❌ "Wrong approach"
✅ "This approach might cause performance issues with large datasets. Consider pagination?"

❌ "Fix this"
✅ "This could throw NullReferenceException. Add null check or use nullable reference types"

🚀 Release Process

1. Create Release Branch

git checkout develop
git pull origin develop
git checkout -b release/v1.0.0

2. Update Version Numbers

• Update version in all csproj files
• Update version in package.json
• Update CHANGELOG.md

3. Final Testing

# Run full test suite
dotnet test
cd frontend && npm test

# Build Docker images
docker-compose build

# Test locally
docker-compose up

4. Merge to Main

git checkout main
git merge release/v1.0.0 --no-ff
git tag -a v1.0.0 -m "Release version 1.0.0"
git push origin main --tags

# Merge back to develop
git checkout develop
git merge release/v1.0.0 --no-ff
git push origin develop

5. Deploy to Production

Triggered automatically by CI/CD when pushing to main with new tag.
