• Designed an adaptable server creation function
• Added dynamic port selection capabilities
• Implemented a standardized health check endpoint
• Ensured clean server lifecycle management

Security Enhancements

• Rigorous path validation to prevent unauthorized file access
• Normalized and resolved file paths with built-in safety checks
• Implemented defensive programming techniques

Future Roadmap

• Expand authentication mechanisms
• Add more granular logging
• Implement advanced file serving capabilities
• Create more comprehensive error handling

Changes Made
