# ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
# TEMPLATE OVERVIEW & USAGE NOTES
# ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
# • TEMPLATE TYPE: COMPREHENSIVE FRAMEWORK TEMPLATE
# • PURPOSE: Production-ready SolidJS application with reactive programming model
# • DESIGN PHILOSOPHY: Self-contained with multi-stage builds and security hardening
# • COMBINATION GUIDANCE: Use standalone for complete SolidJS applications
# • SECURITY CONSIDERATIONS: Non-root user, Alpine base, health monitoring
# • BEST PRACTICES: Layer caching, dependency optimization, production defaults
# • OFFICIAL SOURCES: SolidJS documentation and Docker security guidelines

# ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
# USAGE EXAMPLES & BEST PRACTICES
# ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
# USAGE EXAMPLES
# ==============
# 1. Build production image:
#    docker build --target production -t solidjs-app .
#
# 2. Build development image:
#    docker build --target development -t solidjs-app-dev .
#
# 3. Run production container:
#    docker run -p 3000:3000 solidjs-app
#
# 4. Run development container with hot reload:
#    docker run -p 3000:3000 -v $(pwd):/app solidjs-app-dev
#
# 5. Build with custom build arguments:
#    docker build --target production --build-arg BUILD_ID=1.0.0 -t solidjs-app .
#
# 6. Multi-stage build for CI/CD:
#    docker build --target builder --build-arg NODE_ENV=production .
#
# 7. Health check verification:
#    docker run -d --name solidjs-test -p 3000:3000 solidjs-app
#    docker inspect --format='{{.State.Health.Status}}' solidjs-test
#
# 8. Resource limits for production:
#    docker run -p 3000:3000 --memory=512m --cpus=1 solidjs-app

# BEST PRACTICES
# ==============
# Security:
# • Always run as non-root user (nodejs user created in template)
# • Use specific Node.js version (node:18-alpine) not 'latest'
# • Regularly update base images for security patches
# • Scan images for vulnerabilities: docker scan solidjs-app

# Performance:
# • Multi-stage builds reduce final image size
# • Layer caching optimized with package.json copy first
# • Alpine Linux base image for minimal footprint
# • Production dependencies only in final stage

# Development:
# • Use development stage for local development with hot reload
# • Mount source code as volume for live updates
# • Development stage includes all dependencies for testing
# • Separate build arguments for development vs production

# Operations:
# • Health checks enable proper container orchestration
# • Resource limits prevent memory exhaustion
# • Logging configured for production monitoring
# • Environment-specific configurations via build args

# Maintenance:
# • Regular dependency updates with security scanning
# • Monitor Node.js version compatibility
# • Test with different SolidJS versions
# • Update template with new SolidJS features

# Combination Patterns:
# • Combine with patterns/security-hardened.Dockerfile for enhanced security
# • Combine with patterns/alpine.Dockerfile for further size optimization
# • Combine with tools/nginx.Dockerfile for reverse proxy configuration
# • Combine with patterns/monitoring.Dockerfile for observability

# SolidJS-Specific Considerations:
# • SolidJS uses fine-grained reactivity - optimize build for production
# • SSR (Server-Side Rendering) support available in SolidStart
# • Bundle size optimization critical for performance
# • Consider SolidStart for full-stack applications
