🏗️ Architecture Overview

Core Module (core/)

• BlogWriterService: Main orchestrator that coordinates all blog writing functionality
• Provides a unified interface for research, outline generation, and content creation
• Delegates to specialized modules for specific functionality

Research Module (research/)

• ResearchService: Orchestrates comprehensive research using Google Search grounding
• KeywordAnalyzer: AI-powered keyword analysis and extraction
• CompetitorAnalyzer: Competitor intelligence and market analysis
• ContentAngleGenerator: Strategic content angle discovery

Outline Module (outline/)

• OutlineService: Manages outline generation, refinement, and optimization
• OutlineGenerator: AI-powered outline generation from research data
• OutlineOptimizer: Optimizes outlines for flow, SEO, and engagement
• SectionEnhancer: Enhances individual sections using AI

🔄 Service Flow

1. Research Phase: ResearchService → KeywordAnalyzer + CompetitorAnalyzer + ContentAngleGenerator
2. Outline Phase: OutlineService → OutlineGenerator → OutlineOptimizer
3. Content Phase: (TODO) Content generation and optimization
4. Publishing Phase: (TODO) Platform integration and publishing

🚀 Usage

from services.blog_writer.blog_service import BlogWriterService

# Initialize the service
service = BlogWriterService()

# Research a topic
research_result = await service.research(research_request)

# Generate outline from research
outline_result = await service.generate_outline(outline_request)

# Enhance sections
enhanced_section = await service.enhance_section_with_ai(section, "SEO optimization")

🎯 Key Benefits

1. Modularity

• Each module has a single responsibility
• Easy to test, maintain, and extend
• Clear separation of concerns

2. Reusability

• Components can be used independently
• Easy to swap implementations
• Shared utilities and helpers

3. Scalability

• New features can be added as separate modules
• Existing modules can be enhanced without affecting others
• Clear interfaces between modules

4. Maintainability

• Smaller, focused files are easier to understand
• Changes are isolated to specific modules
• Clear dependency relationships

🔧 Development Guidelines

Adding New Features

1. Identify the appropriate module (research, outline, content, optimization)
2. Create new classes following the existing patterns
3. Update the module's __init__.py to export new classes
4. Add methods to the appropriate service orchestrator
5. Update the main BlogWriterService if needed

Testing

• Each module should have its own test suite
• Mock external dependencies (AI providers, APIs)
• Test both success and failure scenarios
• Maintain high test coverage

Error Handling

• Use graceful degradation with fallbacks
• Log errors appropriately
• Return meaningful error messages to users
• Don't let one module's failure break the entire flow

📈 Future Enhancements

Content Module (content/)

• Section content generation
• Content optimization and refinement
• Multi-format output (HTML, Markdown, etc.)

Optimization Module (optimization/)

• SEO analysis and recommendations
• Readability optimization
• Performance metrics and analytics

Integration Module (integration/)

• Platform-specific adapters (WordPress, Wix, etc.)
• Publishing workflows
• Content management system integration

🔍 Code Quality

• Type Hints: All methods use proper type annotations
• Documentation: Comprehensive docstrings for all public methods
• Error Handling: Graceful failure with meaningful error messages
• Logging: Structured logging with appropriate levels
• Testing: Unit tests for all major functionality
• Performance: Efficient caching and API usage

📝 Migration Notes

The original blog_service.py has been refactored into this modular structure:

• Research functionality → research/ module
• Outline generation → outline/ module
• Service orchestration → core/ module
• Main entry point → blog_service.py (now just imports from core)

All existing API endpoints continue to work without changes due to the maintained interface in BlogWriterService.
