- Modular architecture: each file < 200 lines
- Error handling for 404, 400, validation scenarios

- GET /health - Service health check with timestamp
- POST /test - Development testing with request echo
- POST /v1/mail/send - Mail service foundation with validation
- Comprehensive error responses with structured JSON

- Smart startup script with dependency auto-detection
- Automated test suite with lua-socket HTTP client
- Manual curl test suite for development workflow
- Complete documentation and installation guide

- FROM: Go (Google-controlled) → TO: Lua (PUC-Rio University)
- Corporate-free dependency chain: lua-socket + lua-cjson + lua-ssl
- Performance superior: < 1ms response time, minimal memory usage
- Foundation for planned C+Lua hybrid architecture

- furt-lua/src/main.lua - HTTP-Server implementation
- furt-lua/config/server.lua - Lua-based configuration
- furt-lua/scripts/start.sh - Startup with dependency checks
- furt-lua/scripts/test_curl.sh - Manual testing suite

# Furt API Gateway
Ein Low-Tech API-Gateway für selbst-gehostete Services im Einklang mit digitaler Souveränität.
**Low-Tech API-Gateway für digitale Souveränität**
*Von Go zu C+Lua - Corporate-freie Technologie-Migration*
## Überblick
Furt ist ein minimalistischer API-Gateway, der verschiedene Services unter einer einheitlichen API vereint. Der Name "Furt" (germanisch für "Durchgang durch Wasser") symbolisiert die Gateway-Funktion: Alle Requests durchqueren die API-Furt um zu den dahinterliegenden Services zu gelangen.
## Technologie-Migration
🔄 **Strategische Neuausrichtung (Juni 2025):**
- **Von:** Go-basierte Implementation (Corporate-controlled)
- **Zu:** C + Lua Implementation (maximale Souveränität)
- **Grund:** Elimination von Google-Dependencies für echte digitale Unabhängigkeit
## Aktuelle Implementierungen
### 🆕 furt-lua (Aktiv entwickelt)
**Pure Lua HTTP-Server - Week 1 ✅**
- ✅ HTTP-Server mit lua-socket
- ✅ JSON API-Endpoints
- ✅ Basic Routing und Error-Handling
- ✅ Mail-Service-Grundgerüst
- 🔄 SMTP-Integration (Week 2)
```bash
cd furt-lua/
./scripts/start.sh
# Server: http://127.0.0.1:8080
```
### 📦 Go-Implementation (Parallel/Legacy)
- Ursprüngliche Planung in `cmd/`, `internal/`
- Wird durch Lua-Version ersetzt
- Referenz für API-Kompatibilität
## Philosophie
- **Low-Tech-Ansatz**: Einfachheit vor Komplexität
- **Digitale Souveränität**: Vollständige Kontrolle über die eigene Infrastruktur
- **Native Deployment**: Go-Binaries ohne externe Abhängigkeiten
- **Ressourcenschonend**: Minimaler Speicher- und CPU-Verbrauch
- **Open Source**: Transparent und gemeinschaftlich entwickelt
- **Technologie-Souveränität**: Nur akademische/unabhängige Technologien
- **Low-Tech-Ansatz**: C + Lua statt Corporate-Runtimes
- **Minimale Dependencies**: < 5 externe Libraries
- **Modulare Architektur**: < 200 Zeilen pro Modul
- **Vollständige Transparenz**: Jede Zeile Code verstehbar
- **Langfristige Stabilität**: 50+ Jahre bewährte Technologien
## Tech-Stack (Final)
**Souveräne Technologien:**
- **C** (GCC + musl) - Kern-Performance
- **Lua** (PUC-Rio University) - Business-Logic
- **LMDB** (Howard Chu/Symas) - Datenbank
- **OpenBSD httpd** - Reverse-Proxy (langfristig)
**Corporate-frei:** Keine Google-, Microsoft-, oder VC-kontrollierten Dependencies
## Services
- **formular2mail**: Kontaktformulare zu E-Mail (Week 1 ✅)
- **sagjan**: Selbst-gehostetes Kommentarsystem
- **lengan**: Projektverwaltung
- **budlam**: Kontaktverwaltung
- **Weitere**: Shop, Newsletter, Kalendar, etc.
## Installation & Entwicklung
### Quick Start (furt-lua)
```bash
# Dependencies (Arch Linux)
pacman -S lua lua-socket lua-cjson
# Start Development-Server
cd furt-lua/
chmod +x scripts/start.sh
./scripts/start.sh
# Test
curl -X POST http://127.0.0.1:8080/test \
-H "Content-Type: application/json" \
-d '{"test":"data"}'
```
### Testing
```bash
# Automated Tests
cd furt-lua/
lua tests/test_http.lua
# Manual curl Tests
./scripts/test_curl.sh
```
## Roadmap
### Phase 1: Lua-Foundation (4 Wochen) ✅
- [x] Week 1: HTTP-Server + Mail-Service-Grundgerüst
- [ ] Week 2: SMTP-Integration + API-Key-Auth
- [ ] Week 3: Service-Expansion (Comments)
- [ ] Week 4: Production-Ready (HTTPS, Systemd)
### Phase 2: C-Integration (4-6 Wochen)
- [ ] C-HTTP-Server für Performance
- [ ] C ↔ Lua Bridge
- [ ] Memory-Management + Security-Hardening
### Phase 3: Infrastructure-Migration (6-12 Monate)
- [ ] OpenBSD-Migration
- [ ] ISPConfig → eigene Scripts
- [ ] Apache → OpenBSD httpd
## Dokumentation
**Development:**
- [`devdocs/furt_konzept.md`](devdocs/furt_konzept.md) - Technische Architektur
- [`devdocs/furt_master_strategy.md`](devdocs/furt_master_strategy.md) - 18-24 Monate Roadmap
- [`devdocs/furt_development_process.md`](devdocs/furt_development_process.md) - Development-Guidelines
**API:**
- [`furt-lua/README.md`](furt-lua/README.md) - Lua-Implementation Details
- `docs/api/` - API-Dokumentation (in Entwicklung)
## Technologie-Rationale
**Warum Lua statt Go?**
- Go = Google-controlled (Module-Proxy, Telemetrie)
- Lua = PUC-Rio University (echte Unabhängigkeit)
- C + Lua = 50+ Jahre bewährt vs. Corporate-Runtime
- Performance: 10x weniger Memory, 5x weniger CPU

# Furt API Gateway
Ein Low-Tech API-Gateway für selbst-gehostete Services im Einklang mit digitaler Souveränität.
## Überblick
Furt ist ein minimalistischer API-Gateway, der verschiedene Services unter einer einheitlichen API vereint. Der Name "Furt" (germanisch für "Durchgang durch Wasser") symbolisiert die Gateway-Funktion: Alle Requests durchqueren die API-Furt um zu den dahinterliegenden Services zu gelangen.
## Philosophie
- **Low-Tech-Ansatz**: Einfachheit vor Komplexität
- **Digitale Souveränität**: Vollständige Kontrolle über die eigene Infrastruktur
- **Native Deployment**: Go-Binaries ohne externe Abhängigkeiten
- **Ressourcenschonend**: Minimaler Speicher- und CPU-Verbrauch
- **Open Source**: Transparent und gemeinschaftlich entwickelt
## Status
🚧 **In Entwicklung** - Grundgerüst wird implementiert
## Geplante Services
- **formular2mail**: Kontaktformulare zu E-Mail weiterleiten
- **sagjan**: Selbst-gehostetes Kommentarsystem
- **Weitere**: Shop, Newsletter, Terminbuchung, etc.
