Documentation: services / rssFeedService

Purpose: Generate RSS feed XML for all published blog posts.
Lifecycle Role: Triggered on `/rss.xml` requests.
Dependencies:
Upstream:
  • getAllPosts utility
  • rss XML builder library
Downstream:
  • RSS feed route handlers
Data Flow:
Inputs: Post base directory and site URL.
Outputs: RSS XML string.
Side Effects: None.
Performance and Scalability:
Bottlenecks:
  • File IO delays and XML generation cost proportional to post count.
  • No caching causes redundant regeneration.
Concurrency: Potential performance degradation under high load.
Security and Stability:
Validation: No sanitization of post content for XML compliance.
Vulnerabilities: Malformed XML risk if post data is invalid.
Architecture Assessment:
Coupling: Tied to file IO and external XML library.
Abstraction: No caching or streaming implementation.
Recommendations:
  • Implement caching and regenerate on content changes.
  • Sanitize post content for XML.
  • Stream RSS output for large feeds.
