Lobby Frontend Updates for Global Chat

Overview

The lobby frontend components have been updated to support global chat functionality alongside the existing room-based chat. This allows for seamless integration of global chat features while maintaining backward compatibility with existing room chat implementations.

Updated Components

1. EnhancedChatLobby Component

Location: src/components/game/enhanced-chat-lobby.tsx

New Props:

isGlobalChat?: boolean - Enables global chat mode when set to true

Key Changes:

Dynamic WebSocket URL: Automatically switches between global chat and room chat endpoints
Message Type Handling: Supports both global_message and regular chat_message types
Join Message Types: Uses player_join_global for global chat, join for room chat
Connection Messages: Different success messages for global vs room chat

Usage Example:

// Room chat (existing behavior)
<EnhancedChatLobby 
  lobbyId="room-123" 
  player={player} 
  isGlobalChat={false} 
/>

// Global chat (new functionality)
<EnhancedChatLobby 
  lobbyId="global-chat" 
  player={player} 
  isGlobalChat={true} 
/>

2. ChatLobby Component

Location: src/components/game/chat-lobby.tsx

New Props:

isGlobalChat?: boolean - Enables global chat mode when set to true

Key Changes:

WebSocket Endpoint: Routes to /api/global-chat when isGlobalChat is true
Message Handling: Supports global chat message types
NPC Interactions: Maintains NPC functionality for both modes

Usage Example:

// Room chat
<ChatLobby 
  lobbyId="room-123" 
  player={player} 
  isGlobalChat={false} 
/>

// Global chat
<ChatLobby 
  lobbyId="global-chat" 
  player={player} 
  isGlobalChat={true} 
/>

3. GlobalChatLobby Component (New)

Location: src/components/game/global-chat-lobby.tsx

Features:

Dedicated Global Chat UI: Specialized interface for global chat
Minimizable Interface: Can be minimized or fully collapsed
Global Statistics: Displays platform-wide statistics
Responsive Design: Works on both desktop and mobile

Props:

player: PlayerInfo - Player information
autoConnect?: boolean - Auto-connect to global chat
isModal?: boolean - Display as modal overlay
hideHeader?: boolean - Hide the header section

Usage Example:

<GlobalChatLobby 
  player={player}
  autoConnect={true}
  isModal={false}
  hideHeader={false}
/>

Implementation Examples

1. Adding Global Chat to Existing Pages

Before (Room-only chat):

<EnhancedChatLobby 
  lobbyId={roomId} 
  player={player} 
/>

After (With global chat option):

<EnhancedChatLobby 
  lobbyId={isGlobalChat ? "global-chat" : roomId} 
  player={player} 
  isGlobalChat={isGlobalChat}
/>

2. Creating a Global Chat Only Page

import { GlobalChatLobby } from '@/components/game/global-chat-lobby';

export default function GlobalChatPage() {
  return (
    <div className="min-h-screen bg-background">
      <GlobalChatLobby 
        player={player}
        autoConnect={true}
        isModal={false}
      />
    </div>
  );
}

3. Toggle Between Room and Global Chat

import { useState } from 'react';
import { EnhancedChatLobby } from '@/components/game/enhanced-chat-lobby';

export function ChatToggle() {
  const [isGlobalChat, setIsGlobalChat] = useState(false);
  const [roomId, setRoomId] = useState('room-123');

  return (
    <div>
      <div className="flex gap-2 mb-4">
        <Button 
          onClick={() => setIsGlobalChat(false)}
          variant={!isGlobalChat ? "default" : "outline"}
        >
          Room Chat
        </Button>
        <Button 
          onClick={() => setIsGlobalChat(true)}
          variant={isGlobalChat ? "default" : "outline"}
        >
          Global Chat
        </Button>
      </div>

      <EnhancedChatLobby 
        lobbyId={isGlobalChat ? "global-chat" : roomId}
        player={player}
        isGlobalChat={isGlobalChat}
      />
    </div>
  );
}

WebSocket Connection Logic

Global Chat Connection

// When isGlobalChat = true
const wsUrl = `${protocol}//${window.location.host}/api/global-chat`;

// Join message
ws.send(JSON.stringify({
  type: 'player_join_global',
  player: player
}));

// Send message
ws.send(JSON.stringify({
  type: 'global_message',
  message: message,
  player: player
}));

Room Chat Connection

// When isGlobalChat = false
const wsUrl = `${protocol}//${window.location.host}/api/lobby/${lobbyId}/websocket`;

// Join message
ws.send(JSON.stringify({
  type: 'join',
  player: player
}));

// Send message
ws.send(JSON.stringify({
  type: 'message',
  message: message,
  player: player
}));

Styling and UI Considerations

Global Chat Visual Indicators

GlobalChatLobby Component:

Globe icon (🌐) to distinguish from room chat
Blue color scheme for global chat elements
Online player count badge
Platform statistics display

EnhancedChatLobby/ChatLobby Components:

Dynamic connection messages
Context-aware join notifications
Message type handling for both modes

Responsive Design

Desktop:

Global chat can be displayed as sidebar or overlay
Minimizable interface for non-intrusive experience
Statistics panel for detailed information

Mobile:

Full-width or modal display options
Collapsible interface for space efficiency
Touch-friendly controls

Migration Guide

For Existing Implementations

No Breaking Changes: Existing room chat functionality remains unchanged
Optional Global Chat: Add isGlobalChat prop only when needed
Backward Compatibility: All existing props and functionality preserved

Adding Global Chat Support

Import Updated Components:

import { EnhancedChatLobby } from '@/components/game/enhanced-chat-lobby';
import { GlobalChatLobby } from '@/components/game/global-chat-lobby';

Add Global Chat Option:

<EnhancedChatLobby 
  lobbyId="global-chat"
  player={player}
  isGlobalChat={true}
/>

Handle Global Message Types:

// Message handling is already included in updated components
// No additional code needed for basic functionality

Best Practices

1. User Experience

Provide clear visual distinction between global and room chat
Use appropriate icons and colors for each chat type
Implement smooth transitions between chat modes

2. Performance

Lazy load global chat components when needed
Implement proper cleanup for WebSocket connections
Use efficient message handling for high-volume global chat

3. Accessibility

Maintain keyboard navigation support
Provide screen reader descriptions for chat types
Ensure proper focus management

4. Error Handling

Graceful fallback for connection failures
Clear error messages for users
Automatic reconnection for global chat

Future Enhancements

Conclusion

The lobby frontend updates provide a seamless integration of global chat functionality while maintaining full backward compatibility with existing room chat implementations. The modular approach allows developers to choose the appropriate component and configuration for their specific use case.

The updated components handle all the complexity of WebSocket connections, message routing, and UI state management, making it easy to add global chat support to any existing application.
