1. Overview Diagram

2. Phase 1: Foundation

Goal: Set up development environment and base project.

Verification Command

# Start Docker environment
docker-compose up -d

# Check containers are running
docker-compose ps

# Expected: php, nginx, mysql, redis all "Up"

3. Phase 2: Attribute Routing

Goal: Enable declarative routing with PHP 8 Attributes.

Verification Command

# List all registered routes
docker-compose exec php php spark routes

# Should show routes from #[Route] attributes

4. Phase 3: Domain Layer

Goal: Create pure business logic with no framework dependencies.

Verification Command

# Test EmailValue Object
docker-compose exec php php spark tinker
> $email = new \App\Domain\Shared\ValueObjects\Email('TEST@EXAMPLE.COM');
> echo $email->getValue();  // "test@example.com"

5. Phase 4: Infrastructure

Goal: Implement interfaces defined in Domain.

Verification Command

# Test Redis connection
docker-compose exec redis redis-cli PING
# Output: PONG

6. Phase 5: Modules

Goal: Create self-contained feature packages.

Verification Command

# List modules
docker-compose exec php ls /var/www/html/app/Modules/
# Output: Admin  Api  Member  Web

7. Phase 6: View Components

Goal: Create reusable UI building blocks.

Verification Command

# Check component files exist
docker-compose exec php ls /var/www/html/app/Modules/Admin/Shared/Components/

8. Phase 7: Monitoring & Observability

Goal: Built-in performance tracking and tracing.

Verification Commands

# Fetch Prometheus metrics
curl http://localhost:81/metrics

# Analyze performance
docker-compose exec php php spark monitor:analyze

# Check Redis keys
docker-compose exec redis redis-cli KEYS "perf:*"

9. Phase 8: Documentation

Goal: Self-documenting application with web-based guide.

Verification Command

# Access documentation
curl http://localhost:81/docs

# Check all doc pages exist
docker-compose exec php ls /var/www/html/app/Modules/Web/Docs/Views/

10. Phase 9: Optimizations & Fixes

Goal: Improve performance and stability.

11. Phase 10: Security & Auth

Goal: Secure the application and environment.

12. Phase 11: Feature Expansion

Goal: Enhance UI/UX and Documentation.

13. Docker Verification

Complete System Check

# 1. Check all containers running
docker-compose ps

# 2. Check PHP extensions
docker-compose exec php php -m | grep -E "(redis|pdo_mysql)"

# 3. Check routes registered
docker-compose exec php php spark routes | wc -l

# 4. Check database connection
docker-compose exec php php spark db:table users

# 5. Check Redis connection
docker-compose exec redis redis-cli PING

# 6. Check metrics endpoint
curl -s http://localhost:81/metrics | head -20

# 7. Check documentation
curl -s http://localhost:81/docs | grep -o "<h1>.*</h1>"

File Count Summary

# Count files in each major area
docker-compose exec php bash -c "
echo 'Attributes: ' && find /var/www/html/app/Attributes -name '*.php' | wc -l
echo 'Core: ' && find /var/www/html/app/Core -name '*.php' | wc -l
