+# Frontend Nyla - UI Dokumentation
+
+## Übersicht
+
+Das Frontend Nyla ist eine React-basierte Single-Page-Application (SPA), die mit TypeScript entwickelt wurde. Die Anwendung verwendet Vite als Build-Tool und React Router für das Routing. Die Architektur folgt einem modularen Ansatz mit klarer Trennung von Komponenten, Hooks, Seiten und Geschäftslogik.
+
+---
+
+## 1. Architektur
+
+### 1.1 Architektur-Übersicht
+
+Die Anwendung folgt einer **layered architecture** mit folgenden Ebenen:
+
+```
+┌─────────────────────────────────────────────────────────┐
+│                    Presentation Layer                   │
+│  (Pages, Components, UI Elements)                       │
+├─────────────────────────────────────────────────────────┤
+│                    Business Logic Layer                 │
+│  (Hooks, Logic Files, State Management)                 │
+├─────────────────────────────────────────────────────────┤
+│                    Data Access Layer                    │
+│  (API Client, Authentication)                           │
+├─────────────────────────────────────────────────────────┤
+│                    Infrastructure Layer                 │
+│  (Contexts, Providers, Configuration)                   │
+└─────────────────────────────────────────────────────────┘
+```
+
+### 1.2 Kern-Architektur-Prinzipien
+
+#### 1.2.1 Component-Based Architecture
+- **Komponenten** sind in Feature-Module organisiert
+- Jedes Feature-Modul enthält:
+  - UI-Komponenten (`.tsx`)
+  - Styles (`.module.css`)
+  - Geschäftslogik (`*Logic.tsx`)
+  - Type-Definitionen (`*Types.ts`, `*Interfaces.ts`)
+  - Index-Dateien für saubere Exports
+
+#### 1.2.2 Custom Hooks Pattern
+- Geschäftslogik wird in wiederverwendbare Hooks extrahiert
+- Hooks kapseln API-Aufrufe und State-Management
+- Beispiel: `useWorkflows`, `useFiles`, `useConnections`
+
+#### 1.2.3 Page Management System
+- **PageManager** verwaltet dynamisches Laden und Caching von Seiten
+- Unterstützt:
+  - Lazy Loading für bessere Performance
+  - State Preservation für bestimmte Seiten
+  - Lifecycle-Hooks (onActivate, onDeactivate, onLoad, onUnload)
+  - Animations-basierte Seitenübergänge
+
+#### 1.2.4 Context API für Global State
+- **LanguageContext**: Internationalisierung (i18n)
+- **AuthProvider**: Azure MSAL-basierte Authentifizierung
+
+### 1.3 Technologie-Stack
+
+- **Framework**: React 19.1.0
+- **Build Tool**: Vite 5.4.10
+- **Language**: TypeScript 5.8.3
+- **Routing**: React Router DOM 7.7.1
+- **State Management**: React Hooks + Context API
+- **HTTP Client**: Axios 1.8.3
+- **Authentication**: Azure MSAL (@azure/msal-browser, @azure/msal-react)
+- **Animations**: Framer Motion 12.7.3
+- **State Machine**: XState 5.20.1
+- **Styling**: CSS Modules
+- **Icons**: React Icons 5.5.0
+
+### 1.4 Authentifizierung & Sicherheit
+
+- **Azure MSAL Integration**: OAuth2/OIDC-basierte Authentifizierung
+- **Protected Routes**: Route-Guards für geschützte Bereiche
+- **Token Management**: Automatische Token-Erneuerung und -Validierung
+- **API Interceptors**: Automatisches Hinzufügen von Authorization-Headern
+
+### 1.5 Internationalisierung (i18n)
+
+- Unterstützte Sprachen: Deutsch (de), Englisch (en), Französisch (fr)
+- Dynamisches Laden von Übersetzungen
+- Browser-Sprache-Erkennung
+- Persistierung der Sprachauswahl in localStorage

+```
+
+### 2.2 Feature-Module Struktur
+
+Jedes Feature-Modul folgt einem konsistenten Muster:
+
+```
+FeatureModule/
+├── ComponentName.tsx                  # Haupt-Komponente
+├── ComponentName.module.css          # Komponenten-Styles
+├── featureLogic.tsx                  # Geschäftslogik
+├── featureTypes.ts                   # TypeScript Types
+├── featureInterfaces.ts              # TypeScript Interfaces (optional)
+└── index.ts                          # Public API Export
+```
+
+**Beispiel: Connections Module**
+```
+Connections/
+├── ConnectionsTable.tsx              # Haupt-Tabellen-Komponente
+├── ConnectionsTable.module.css      # Tabellen-Styles
+├── ConnectionEditModal.tsx          # Edit-Modal Komponente
+├── ConnectionEditModal.module.css   # Modal-Styles
+├── ConnectionsErrorDisplay.tsx      # Error-Display Komponente
+├── ConnectionsErrorDisplay.module.css
+├── connectionsLogic.tsx              # Geschäftslogik
+├── connectionsInterfaces.ts         # Type Definitions
+└── index.ts                          # Exports
+```
+
+### 2.3 Seiten-Struktur
+
+Seiten sind in `pages/Home/` organisiert und verwenden:
+- **Shared Styles**: `pages.module.css` für gemeinsame Seiten-Styles
+- **Feature Components**: Importieren entsprechende Komponenten aus `components/`
+- **Hooks**: Nutzen Custom Hooks für Daten-Fetching und State-Management
+- **Language Context**: Nutzen `useLanguage()` für i18n
+
+### 2.4 Naming Conventions
+
+- **Komponenten**: PascalCase (z.B. `DashboardChat.tsx`)
+- **Hooks**: camelCase mit "use" Prefix (z.B. `useWorkflows.ts`)
+- **Logic Files**: camelCase mit "Logic" Suffix (z.B. `connectionsLogic.tsx`)
+- **Types/Interfaces**: camelCase mit "Types"/"Interfaces" Suffix
+- **CSS Modules**: `.module.css` Suffix
+- **Internal Functions**: Prefix mit `_` (z.B. `_internalFunction()`)

+
+### 3.8 Critical Dependency Paths
+
+#### Authentication Flow
+```
+App.tsx
+  └── AuthProvider
+      └── ProtectedRoute
+          └── Home
+              └── [All Protected Pages]
+```
+
+#### Data Fetching Flow
+```
+Page Component
+  └── Feature Component
+      └── Custom Hook (useWorkflows, useFiles, etc.)
+          └── useApiRequest
+              └── api.ts (Axios)
+                  └── Backend API
+```
+
+#### Page Loading Flow
+```
+App.tsx
+  └── Router
+      └── Home
+          └── PageManager
+              └── pageConfigs
+                  └── Lazy Component
+                      └── Page Component
+```
+
+#### Internationalization Flow
+```
+App.tsx
+  └── LanguageProvider
+      └── [All Components]
+          └── useLanguage()
+              └── locales/[lang].ts

+## 4. Wichtige Architektur-Entscheidungen
+
+### 4.1 Lazy Loading
+- Seiten werden lazy geladen für bessere Initial Load Performance
+- Implementiert via `React.lazy()` in `pageConfigs.ts`
+
+### 4.2 State Preservation
+- Dashboard-Seite behält State bei Navigation
+- Implementiert via `preserveState` Flag in PageConfig
+- PageManager verwaltet preserved Instances separat
+
+### 4.3 CSS Modules
+- Scoped Styling für bessere Isolation
+- Konfiguriert in `vite.config.ts`
+
+### 4.4 Error Handling
+- Zentralisiertes Error Handling in `useApi.ts`
+- Formatierung von Backend-Errors für konsistente UX
+
+### 4.5 Theme Management
+- CSS Variables für Light/Dark Theme
+- Persistierung in localStorage
+- Automatische Browser-Präferenz-Erkennung
+
+---
+
+## 5. Entwicklung & Build
+
+### 5.1 Development Scripts
+- `npm run dev`: Development Server (Port 5176, Mode: dev)
+- `npm run dev:prod`: Development mit Production Environment
+- `npm run dev:int`: Development mit Integration Environment
+
+### 5.2 Build Scripts
+- `npm run build`: Standard Build
+- `npm run build:prod`: Production Build
+- `npm run build:int`: Integration Build
+
+### 5.3 Environment Variables
+- Präfix: `VITE_`
+- Konfiguriert in `.env.dev`, `.env.int`, `.env.prod`
+- Zugriff via `import.meta.env.VITE_*`
+
+---
+
+## 6. Best Practices & Patterns
+
+### 6.1 Component Organization
+- Feature-basierte Organisation
+- Separation of Concerns (UI, Logic, Types)
+- Index-Dateien für saubere Exports
+
+### 6.2 Hook Patterns
+- Custom Hooks für wiederverwendbare Logik
+- API-Hooks nutzen `useApiRequest` für Konsistenz
+- State Management in Hooks, nicht in Components
+
+### 6.3 Type Safety
+- TypeScript für alle Dateien
+- Zentrale Type-Definitionen in Feature-Modulen
+- Interfaces für API-Responses
+
+### 6.4 Code Style
+- camelCase für Variablen und Funktionen
+- PascalCase für Komponenten
+- `_` Prefix für interne Funktionen
+- Keine snake_case
+
+---
+
+## 7. Erweiterungen & Wartung
+
+### 7.1 Neue Seite hinzufügen
+1. Page-Komponente in `pages/Home/` erstellen
+2. Lazy Import in `pageConfigs.ts` hinzufügen
+3. PageConfig mit Metadaten erstellen
+4. Bei Bedarf Feature-Komponenten erstellen
+
+### 7.2 Neues Feature-Modul hinzufügen
+1. Verzeichnis in `components/` erstellen
+2. Komponenten, Logic, Types, Styles hinzufügen
+3. Index-Datei für Exports erstellen
+4. Custom Hook in `hooks/` erstellen (falls API-Calls benötigt)
+
+### 7.3 Neue API-Endpoints integrieren
+1. Hook in `hooks/` erstellen oder erweitern
+2. `useApiRequest` nutzen für API-Calls
+3. Types für Request/Response definieren
+4. Error Handling implementieren
+
