- Remove Go artifacts (cmd/, internal/, pkg/, go.mod)
- Move furt-lua/* content to repository root
- Restructure as clean src/, config/, scripts/, tests/ layout
- Rewrite README.md as practical tool documentation
- Remove timeline references and marketing language
- Clean .gitignore from Go-era artifacts
- Update config/server.lua with example.org defaults
- Add .env.production to .gitignore for security
Repository now ready for open source distribution with minimal,
focused structure and generic configuration templates.
close issue DAW/furt#86
- Add comprehensive API-key authentication system with X-API-Key header validation
- Implement permission-based access control (mail:send, * for admin)
- Add rate-limiting system (60 req/hour per API key, 100 req/hour per IP)
- Refactor monolithic 590-line main.lua into 6 modular components (<200 lines each)
- Add IP-restriction support with CIDR notation (127.0.0.1, 10.0.0.0/8)
- Implement Hugo integration with CORS support for localhost:1313
- Add production-ready configuration with environment variable support
- Create comprehensive testing suite (auth, rate-limiting, stress tests)
- Add production deployment checklist and cleanup scripts
This refactoring transforms the API gateway from a single-file monolith into a
biocodie-compliant modular architecture while adding enterprise-grade security
features. Performance testing shows 79 RPS concurrent throughput with <100ms
latency. Hugo contact form integration tested and working. System is now
production-ready for deployment to walter/aitvaras.
Resolves#47
- Add CORS headers to all API responses in main.lua
- Implement OPTIONS preflight request handling
- Add environment-variable based CORS origin configuration
- Create production.env.example for deployment documentation
- Update .env.example with CORS_ALLOWED_ORIGINS setting
Resolves cross-origin request blocking for Hugo dev server integration.
CORS origins now configurable via CORS_ALLOWED_ORIGINS environment variable
for production deployments while maintaining dev-friendly defaults.
Related to #49
- Add native Lua SMTP client with SSL/TLS support for mail.dragons-at-work.de:465
- Implement POST /v1/mail/send endpoint with real email delivery functionality
- Add environment variable integration (SMTP_*) for secure credential management
- Add comprehensive input validation and error handling for mail requests
- Add health check endpoint with SMTP configuration status reporting
- Add multi-line SMTP response handling for robust server communication
- Add request ID tracking system for debugging and monitoring
- Update start.sh script for automatic .env loading and dependency checking
- Add complete testing suite for SMTP functionality verification
This completes the Week 2 Challenge migration from Go to pure Lua HTTP server
with full production-ready SMTP capabilities. The implementation eliminates all
Google/corporate dependencies while achieving superior performance (18ms response
time) and maintaining digital sovereignty principles.
Real mail delivery confirmed: test email successfully sent to admin@dragons-at-work.de
Ready for Hugo website integration and production deployment with security layer.
