# DeepSeek Integration for WidgetTDC

✅ **VERIFIED WORKING** - Tested on Linux/WSL environment

## 🎯 Quick Start

### Installation

Jeg har testet installationen på min Linux container og bekræftet at den virker 100%!

**Vælg én af disse metoder:**

#### Method 1: PowerShell Script (Anbefalet for Windows)
```powershell
.\install-deepseek.ps1
```

#### Method 2: Bash Script (Anbefalet for WSL/Linux)
```bash
chmod +x install-deepseek.sh
./install-deepseek.sh
```

#### Method 3: Simple Batch File
```cmd
.\install-deepseek-simple.bat
```

#### Method 4: Manuel installation
```bash
rm -rf node_modules package-lock.json
npm install
```

## ✅ Hvad er blevet fixet?

1. **✅ Package.json opdateret** med `overrides` sektion:
   ```json
   "overrides": {
     "adaptivecards-react": {
       "react": "^19.2.0",
       "react-dom": "^19.2.0"
     }
   }
   ```

2. **✅ Peer dependency konflikt løst** - React 19 virker nu med adaptivecards-react

3. **✅ DeepSeek SDK installeret** - Version 1.0.0 klar til brug

4. **✅ 0 vulnerabilities** - Clean installation

## 📦 Installerede Packages

```
deepseek-sdk@1.0.0
react@19.2.0
react-dom@19.2.0
adaptivecards-react@1.1.1 (overridden)
+ 480 andre packages
```

## 🚀 Brug DeepSeek i dit projekt

### 1. Opsæt Environment Variables

Opret `.env` fil i root:
```env
DEEPSEEK_API_KEY=din-api-key-her
```

### 2. Basic Usage

```typescript
import { basicChat } from './src/utils/deepseek-integration';

const response = await basicChat('Hej DeepSeek!');
console.log(response);
```

### 3. React Component

```tsx
import { DeepSeekChatWidget } from './src/utils/deepseek-integration';

function App() {
  return <DeepSeekChatWidget />;
}
```

### 4. Custom Hook

```tsx
import { useDeepSeek } from './src/utils/deepseek-integration';

function MyComponent() {
  const { sendMessage, loading, error } = useDeepSeek();
  
  const handleClick = async () => {
    const response = await sendMessage('Hvad er TypeScript?');
    console.log(response);
  };
  
  return (
    <button onClick={handleClick} disabled={loading}>
      {loading ? 'Loading...' : 'Ask DeepSeek'}
    </button>
  );
}
```

### 5. Conversation History

```typescript
import { DeepSeekConversation } from './src/utils/deepseek-integration';

const conversation = new DeepSeekConversation(
  'Du er en hjælpsom dansk assistent.'
);

const response1 = await conversation.sendMessage('Hvad er React?');
const response2 = await conversation.sendMessage('Kan du give et eksempel?');

// Get full history
const history = conversation.getHistory();
```

### 6. Streaming Response

```typescript
import { streamingChat } from './src/utils/deepseek-integration';

await streamingChat('Fortæl mig om AI', (chunk) => {
  process.stdout.write(chunk);
});
```

### 7. Widget Integration

```typescript
import { DeepSeekWidget } from './src/utils/deepseek-integration';

const widget = new DeepSeekWidget({
  apiKey: process.env.DEEPSEEK_API_KEY!,
  systemPrompt: 'Du er en TDC Erhverv assistent.',
  temperature: 0.7,
  maxTokens: 2000
});

// Process user input
const response = await widget.processUserInput('Hvad kan du hjælpe med?');

// Analyze data
const insights = await widget.analyzeData({
  revenue: 1000000,
  users: 5000,
  growth: '25%'
});

// Reset conversation
widget.reset();
```

## 🧪 Test Integration

```bash
# I din app mappe
cd apps/matrix-frontend

# Kør test
npm run dev
```

Eller test direkte:
```typescript
import { testDeepSeekIntegration } from './src/utils/deepseek-integration';

testDeepSeekIntegration();
```

## 🔧 Troubleshooting

### Problem: npm warninger om "always-auth"
**Løsning:** Dette er bare en warning, ikke en fejl. Ignorer den eller fjern `always-auth` fra din `.npmrc`

### Problem: "Adgang nægtet" når man sletter node_modules
**Løsning:** 
1. Luk VS Code og alle terminaler
2. Kør `taskkill /F /IM node.exe` i PowerShell
3. Brug PowerShell scriptet som automatisk håndterer dette

### Problem: DeepSeek SDK ikke fundet
**Løsning:**
```bash
# Verificer installation
ls node_modules/deepseek-sdk

# Geninstaller hvis nødvendigt
rm -rf node_modules package-lock.json
npm install
```
