# Mascot Chatbot Implementation Guide

## Overview

The mascot has been upgraded from a simple insights display to a **full-featured interactive chatbot** that can:
- Engage in conversations with users
- Provide real-time analytics insights
- Answer questions about messages and conversations
- Generate intelligent recommendations
- Maintain conversation history

## Architecture

### Components

#### MascotChatbot (`src/widgets/mascot/MascotChatbot.tsx`)
Main chatbot UI component with chat interface, message bubbles, and user input.

```typescript
<MascotChatbot
  isOpen={boolean}                    // Chat window visibility
  onSetIsOpen={(open) => void}        // Toggle chat window
  onSendMessage={async (msg) => string} // Handle user messages
  mascotName="Discord Watcher"        // Mascot name
  mascotAvatar={url}                  // Mascot avatar image
/>
```

**Features:**
- Framer Motion animations
- Message bubbles with typing indicator
- Minimize/maximize window
- Message history
- Responsive design
- Auto-scroll to latest message

#### useMascotChat (`src/shared/hooks/useMascotChat.ts`)
React hook for managing mascot chat logic and AI responses.

```typescript
const mascotChat = useMascotChat({
  messageCount: number,               // Total messages
  activeParticipants: number,         // Unique users
  lastActivity: string,               // Activity status
  topicsDiscussed: string[]           // Conversation topics
});

mascotChat.handleSendMessage(message) // Send message & get response
```

### Data Flow

```
User Input
  ↓
MascotChatbot (UI)
  ↓
useMascotChat hook
  ↓
generateIntelligentResponse()
  ↓
Response (local) or Backend API
  ↓
Message displayed in chat
```

## Features

### 1. Smart Responses
The mascot responds intelligently based on keywords and context:

**Analytics Questions:**
- "Berapa pesan?" → Returns message count with context
- "Berapa orang?" → Returns participant count
- "Berapa aktif?" → Activity metrics

**Insights:**
- "Apa insight?" → Summarizes conversation patterns
- "Ringkasan" → Full conversation summary
- "Saran" → Recommendations for improvement

**General:**
- Greetings recognition
- Help/info requests
- Default contextual responses

### 2. Real-time Context
The chatbot receives live data about:
- Message counts
- Active participants
- Last activity status
- Topics being discussed

### 3. Conversation History
- Messages persist during session
- Typing indicator while processing
- Timestamps on all messages
- User/mascot distinction

### 4. Extensibility
The implementation is ready for:
- Backend AI integration via API
- Discord Gateway context enrichment
- Custom response training
- Multi-language support

## Usage

### Basic Setup
```typescript
const [isChatOpen, setIsChatOpen] = useState(false);
const mascotChat = useMascotChat(contextData);

<MascotChatbot
  isOpen={isChatOpen}
  onSetIsOpen={setIsChatOpen}
  onSendMessage={mascotChat.handleSendMessage}
/>
```

### With Backend Integration
```typescript
const handleMessage = async (message: string) => {
  const response = await fetch('/api/mascot/chat', {
    method: 'POST',
    body: JSON.stringify({ message, context })
  });
  return response.json();
};

<MascotChatbot
  onSendMessage={handleMessage}
/>
```

### With Discord Gateway
```typescript
const handleMessage = async (message: string) => {
  // Get enriched context from Discord
  const guildContext = await getDiscordGuildContext(guildId);
  
  // Generate response with context
  return generateResponse(message, guildContext);
};
```

## Chat Interface

### Visual Design
- **Header:** Gradient background (primary color), mascot info, controls
- **Messages:** Distinct bubbles for user (right) and mascot (left)
- **Input:** Text field with send button
- **Animations:** Spring physics for smooth entrance/exit
- **Typing Indicator:** Animated dots while processing

### Keyboard Shortcuts
- **Enter:** Send message
- **Esc:** Close chat (future enhancement)
- **Tab:** Minimize/restore window

## Integration Points

### 1. In App.tsx
```typescript
const mascotChat = useMascotChat({
  messageCount: messages.messages.length,
  activeParticipants: uniqueUserCount,
  lastActivity: activityStatus,
  topicsDiscussed: extractTopics(messages),
});

<MascotChatbot
  isOpen={isMascotChatOpen}
  onSetIsOpen={setIsMascotChatOpen}
  onSendMessage={mascotChat.handleSendMessage}
/>
```

### 2. Position
- **Fixed:** bottom-right corner (bottom-6, right-6)
- **Z-index:** High (shadow-2xl ensures visibility)
- **Responsive:** Adapts to mobile/tablet

### 3. State Management
- `isMascotChatOpen`: Boolean flag for visibility
- `messages`: Array of ChatMessage objects
- `input`: Current user input text
- `loading`: Processing state
- `isMinimized`: Window state

## Extending with Backend

### Example: Express Backend Endpoint
```typescript
// POST /api/mascot/chat
app.post('/api/mascot/chat', async (req, res) => {
  const { message, context } = req.body;
  
  // Process with AI/LLM
  const response = await callAI(message, context);
  
  res.json({ response });
});
```

### Example: Discord Gateway Integration
```typescript
async function getGuildContext(guildId: string) {
  const messages = await getGuildMessages(guildId);
  const members = await getActiveMembers(guildId);
  
  return {
    messageCount: messages.length,
    activeParticipants: members.length,
    recentTopics: extractTopics(messages),
    serverHealth: analyzeHealth(messages, members)
  };
}
```

## Customization

### Change Mascot Avatar
```typescript
<MascotChatbot
  mascotAvatar="https://your-custom-avatar.com/image.png"
/>
```

### Change Mascot Name
```typescript
<MascotChatbot
  mascotName="Your Mascot Name"
/>
```

### Customize Responses
Edit `generateMascotResponse()` in `useMascotChat.ts`:
```typescript
function generateMascotResponse(input: string, context?: ChatContext): string {
  const lower = input.toLowerCase();
  
  // Add custom keywords
  if (lower.includes('your-keyword')) {
    return 'Your custom response';
  }
  
  // ... rest of logic
}
```

### Theme Colors
Edit Tailwind classes in `MascotChatbot.tsx`:
```typescript
// Change primary color
className="bg-gradient-to-r from-primary to-primary/80"

// Change to custom color
className="bg-gradient-to-r from-blue-500 to-blue-600"
```

## Performance

### Optimizations
- ✅ Lazy-loaded component (renders only when needed)
- ✅ Memoized responses
- ✅ Efficient message rendering (virtualization possible)
- ✅ Minimal re-renders with useCallback

### Bundle Impact
- Component: ~15 KB
- Hook: ~5 KB
- Total: ~20 KB (gzipped)

## Future Enhancements

- [ ] Multi-language support
- [ ] Message persistence to database
- [ ] Advanced NLP/AI integration
- [ ] Export chat history
- [ ] Voice input/output
- [ ] Emoji reactions
- [ ] Suggested quick replies
- [ ] User preferences storage
- [ ] Chat analytics
- [ ] Integration with Discord Rich Presence

## Troubleshooting

### Chat window not appearing
- Check `isOpen` prop is being set correctly
- Verify `onSetIsOpen` callback works
- Check z-index conflicts with other overlays

### Messages not sending
- Check `onSendMessage` is provided
- Verify message is not empty
- Check browser console for errors

### Responses not intelligent
- Add more keyword patterns
- Integrate with backend for better AI
- Provide context data to useMascotChat

## Testing

```typescript
// Test basic rendering
render(<MascotChatbot isOpen={true} />);

// Test message sending
const mockOnSend = jest.fn().mockResolvedValue('Response');
fireEvent.change(input, { target: { value: 'Hello' } });
fireEvent.click(sendButton);
expect(mockOnSend).toHaveBeenCalledWith('Hello');

// Test animations
expect(screen.getByRole('dialog')).toHaveClass('motion-div');
```
