+```
+
+### **Component Integration**
+
+The ChatBoxComponent is already integrated into Lowcoder. To use it:
+
+1. **In Lowcoder Editor**: Drag "ChatBox" component from the component panel
+2. **Configure Properties**:
+   - **Mode**: `local`, `collaborative`, or `hybrid`
+   - **User ID**: Unique identifier for the user
+   - **User Name**: Display name for the user
+   - **Room ID**: Chat room identifier
+   - **Server URL**: WebSocket server URL (for collaborative mode)
+
+---
+
+## 🧪 **Testing & Debugging**
+
+### **🚀 Quick Testing Guide**
+
+#### **Step 1: Start the WebSocket Server**
+
+Choose either ES modules (.js) or CommonJS (.cjs) version:
+
+```bash
+# Method 1: ES modules (recommended)
+cd client/packages/lowcoder
+node yjs-websocket-server.js
+
+# Method 2: CommonJS (alternative)
+cd client/packages/lowcoder  
+node yjs-websocket-server.cjs
+```
+
+**Expected Output:**
+```
+🚀 Starting Yjs WebSocket Server...
+📡 Server will run on: ws://localhost:3001
+🔌 WebSocket server created
+✅ Yjs WebSocket Server is running!
+📡 WebSocket endpoint: ws://localhost:3001
+🏥 Health check: http://localhost:3001/health
+```
+
+#### **🔥 Step 2: Test Real-time Multi-Browser Synchronization**
+
+1. **First Browser Tab/Window:**
+   ```
+   - Add ChatBox component
+   - Set Mode: "Collaborative (Real-time)"
+   - Set User ID: "alice_123"
+   - Set User Name: "Alice"
+   - Set Room ID: "test_room"
+   ```
+
+2. **Second Browser Tab/Window (or different browser):**
+   ```
+   - Add ChatBox component  
+   - Set Mode: "Collaborative (Real-time)"
+   - Set User ID: "bob_456"
+   - Set User Name: "Bob"
+   - Set Room ID: "test_room" (SAME!)
+   ```
+
+3. **Send Messages:**
+   ```
+   - Alice sends: "Hello from Alice!"
+   - Bob sends: "Hi Alice, this is Bob!"
+   - Messages should appear INSTANTLY in both browsers
+   ```
+
+#### **✅ Expected Console Logs (Success Indicators):**
+
+**YjsPluvProvider Logs:**
+```
+[YjsPluvProvider] 🚀 CONNECT called with config: {mode: "collaborative", ...}
+[YjsPluvProvider] 📄 Creating new Y.Doc for room: test_room
+[YjsPluvProvider] 🔗 Creating WebSocket connection...
+[YjsPluvProvider]   📡 URL: ws://localhost:3001
+[YjsPluvProvider]   🏠 Room: test_room
+[YjsPluvProvider] ✅ Created new Y.Doc and WebSocket provider
+[YjsPluvProvider] 📡 WebSocket status changed: connected
+[YjsPluvProvider] ✅ WebSocket connected - real-time sync enabled!
+[YjsPluvProvider] 🔄 Document sync status: synced
+```
+
+**Message Synchronization Logs:**
+```
+[YjsPluvProvider] 📤 SENDING MESSAGE:
+[YjsPluvProvider]   💬 Text: Hello from Alice!
+[YjsPluvProvider]   👤 Author: Alice (alice_123)
+[YjsPluvProvider]   🏠 Room: test_room
+[YjsPluvProvider] ✅ MESSAGE STORED in Yjs map
+[YjsPluvProvider] 🔔 MESSAGES MAP CHANGED!
+[YjsPluvProvider] 🆕 NEW MESSAGE DETECTED:
+[YjsPluvProvider] ✅ Notified subscribers for room: test_room
+```
+
+#### **🧪 Advanced Testing Scenarios**
+
+**Test 1: Multiple Devices/Browsers**
+1. Open the app in **Chrome, Firefox, and Safari**
+2. Use the **same Room ID** in all browsers
+3. Send messages from each browser
+4. Verify **instant synchronization** across ALL browsers
+
+**Test 2: Network Resilience**
+1. **Disconnect WiFi** while chatting
+2. **Send messages** (should queue locally)
+3. **Reconnect WiFi**
+4. Verify **messages sync** when connection restored
+
+**Test 3: Server Restart**
+1. **Stop WebSocket server** (Ctrl+C)
+2. **Send messages** (should work locally)
+3. **Restart server** (`node yjs-websocket-server.js`)
+4. Verify **automatic reconnection** and sync
+
+**Test 4: Multiple Rooms**
+1. Open **4 browser tabs**
+2. Tabs 1-2 use Room ID: "room_alpha"
+3. Tabs 3-4 use Room ID: "room_beta"
+4. Send messages in both rooms
+5. Verify **room isolation** (messages only sync within same room)
+
+### **🔍 Debug Mode & Logging**
+
+```javascript
+// Enable detailed logging by checking browser console
+// All operations are logged with prefixes:
+
+// 🟢 YjsPluvProvider logs
+[YjsPluvProvider] 🚀 CONNECT called...
+[YjsPluvProvider] 📄 Creating new Y.Doc for room...
+[YjsPluvProvider] 🔗 Creating WebSocket connection...
+[YjsPluvProvider] ✅ WebSocket connected...
+
+// 🟡 HybridChatManager logs  
+[HybridChatManager] 🏠 Creating room from request...
+[HybridChatManager] 🔍 Getting available rooms...
+[HybridChatManager] 🚪 User joining room...
+
+// 🔵 ALASqlProvider logs (fallback)
+[ALASqlProvider] 📦 Local storage operations...
+```
+
+### **🔧 Development Commands**
+
+```bash
+# Navigate to working directory
+cd client/packages/lowcoder
+
+# Start WebSocket server (choose one)
+node yjs-websocket-server.js     # ES modules
+node yjs-websocket-server.cjs    # CommonJS
+
+# Start development server (in separate terminal)
+yarn start
+
+# Build for production
+yarn build
+
+# Health check WebSocket server
+curl http://localhost:3001/health
+```
+
+### **🐛 Common Issues & Solutions**
+
+**Problem: "Failed to setup Yjs connection"**
+- **Solution**: Ensure WebSocket server is running on port 3001
+- Check firewall/antivirus settings
+- Try using `.cjs` version if `.js` fails
+
+**Problem: Messages not syncing between tabs**
+- **Solution**: Verify both tabs use **exactly the same Room ID**
+- Check browser console for connection logs
+- Ensure mode is set to "Collaborative"
+- Restart WebSocket server
+
+**Problem: WebSocket connection fails**
+- **Solution**: Check if port 3001 is available
+- Try different port: `PORT=3002 node yjs-websocket-server.js`
+- Update serverUrl in chat config to match
+
+**Problem: Import/Export errors**
+- **Solution**: Ensure `y-websocket` package is installed: `yarn add y-websocket`
+- Check Node.js version (requires Node 16+)
+- Try deleting `node_modules` and running `yarn install`
+
+### **🚑 Health Checks**
+
+```bash
+# Check WebSocket server health
+curl http://localhost:3001/health
+
+# Expected response:
+{
+  "status": "healthy",
+  "uptime": "00:05:32",
+  "connections": 2,
+  "rooms": ["test_room", "general"]
+}
+```

+  
+  // Optional settings
+  description?: string;         // Room description
+  maxParticipants?: number;     // Participant limit
+}
+```
+
+### **⚙️ Provider Architecture**
+
+#### **ChatDataProvider Interface**
+The `ChatDataProvider` interface ensures consistent API across different storage backends:
+
+```typescript
+interface ChatDataProvider {
+  // Connection management
+  connect(config: ConnectionConfig): Promise<OperationResult<void>>;
+  disconnect(): Promise<OperationResult<void>>;
+  getConnectionState(): ConnectionState;
+  isConnected(): boolean;
+  
+  // Core operations
+  sendMessage(message: Omit<UnifiedMessage, 'id' | 'timestamp'>): Promise<OperationResult<UnifiedMessage>>;
+  getMessages(roomId: string, limit?: number): Promise<OperationResult<UnifiedMessage[]>>;
+  createRoom(room: Omit<UnifiedRoom, 'id' | 'createdAt'>): Promise<OperationResult<UnifiedRoom>>;
+  getRooms(userId?: string): Promise<OperationResult<UnifiedRoom[]>>;
+  
+  // Real-time subscriptions
+  subscribeToRoom(roomId: string, callback: (event: ChatEvent) => void): UnsubscribeFunction;
+  subscribeToPresence(roomId: string, callback: (users: UserPresence[]) => void): UnsubscribeFunction;
+  subscribeToTyping(roomId: string, callback: (typingUsers: TypingState[]) => void): UnsubscribeFunction;
+}
+```
+

+Main React hook for chat functionality:
+
+```typescript
+const {
+  // Connection state
+  isConnected,
+  connectionState,
+  
+  // Core chat operations
+  sendMessage,
+  messages,
+  
+  // Room management
+  currentRoom,
+  joinedRooms,
+  createRoom,
+  joinRoom,
+  leaveRoom,
+  
+  // Real-time features
+  onlineUsers,
+  typingUsers,
+  startTyping,
+  stopTyping,
+  
+  // Lifecycle
+  connect,
+  disconnect
+} = useChatManager({
+  userId: 'user_123',
+  userName: 'John Doe',
+  applicationId: 'my_app',
+  roomId: 'general',
+  mode: 'collaborative', // 'local' | 'collaborative' | 'hybrid'
+  autoConnect: true
+});
+```
+
+### **Component Properties**
+
+```typescript
+interface ChatBoxProps {
+  // User configuration
+  userId: string;                // Unique user identifier

+  applicationId: string;         // App identifier for data isolation
+  
+  // Room configuration
+  roomId: string;                // Initial room to join
+  mode: 'local' | 'collaborative' | 'hybrid';
+  
+  // Server configuration (for collaborative mode)
+  serverUrl?: string;            // WebSocket server URL
+  
+  // UI configuration
+  autoHeight: boolean;           // Adjust height automatically
+  showTypingIndicators: boolean; // Display typing indicators
+  showOnlineUsers: boolean;      // Display online user list
+  
+  // Room management

+  maxRoomsDisplay: number;       // Limit room list size
+  
+  // Event handlers
+  onEvent: (event: EventType) => void;
+}
+```
+
+### **Error Handling**
+
+```typescript
+// All operations return OperationResult
+interface OperationResult<T = any> {
+  success: boolean;
+  data?: T;
+  error?: string;
+  timestamp: number;
+}
+
+// Usage example
+const result = await sendMessage('Hello world!');
+if (!result.success) {
+  console.error('Failed to send message:', result.error);
+  // Handle error appropriately
+}
+```
+
+### **Usage Examples**
+
+#### **Basic Local Chat**
+```typescript
+// Simple local chat setup
+<ChatBoxComponent
+  userId="user_123"
+  userName="John Doe"
+  applicationId="my_app"
+  roomId="general"
+  mode="local"
+  autoHeight={true}
+  showTypingIndicators={true}
+/>
+```
+
+#### **Real-time Collaborative Chat**
+```typescript
+// Real-time collaborative chat with room management
+<ChatBoxComponent
+  userId="alice_456"
+  userName="Alice Smith"

+
+## ⚠️ **Known Issues & Limitations**
+
+### **Current Limitations**
+
+1. **File Attachments**: Not yet implemented - text messages only
+2. **Message History**: Limited to 1000 messages per room (configurable)
+3. **User Presence**: Basic online/offline - no rich presence status
+4. **Mobile Support**: Optimized for desktop, mobile experience needs improvement
+5. **Scalability**: WebSocket server not production-ready (single instance)
+
+### **Browser Compatibility**
+
+| Browser | Status | Notes |
+|---------|--------| ----- |
+| Chrome 90+ | ✅ Full Support | Recommended browser |
+| Firefox 85+ | ✅ Full Support | All features working |
+| Safari 14+ | ✅ Full Support | WebSocket limitations on iOS |
+| Edge 90+ | ✅ Full Support | Chromium-based versions |
+| IE 11 | ❌ Not Supported | Missing WebSocket and ES6 features |
+
+### **Production Considerations**
+
+1. **WebSocket Server**: Current server is for development only
+   - **Solution**: Deploy production-grade WebSocket infrastructure
+   - **Alternatives**: Consider Socket.io, Pusher, or Ably for production
+
+2. **Data Persistence**: Yjs server doesn't persist data between restarts
+   - **Solution**: Implement Redis or database backend for persistence
+
+3. **Authentication**: No built-in authentication mechanism
+   - **Solution**: Integrate with your app's authentication system
+
+4. **Rate Limiting**: No protection against message spam
+   - **Solution**: Implement server-side rate limiting
+
+---
+
+## 🤝 **Contributing Guidelines**
+
+### **Development Workflow**
+
+```bash
+# 1. Create feature branch
+git checkout -b feature/message-reactions
+
+# 2. Make incremental changes
+# - Follow small, testable implementations
+# - Update types in chatDataTypes.ts first
+# - Implement in providers
+# - Update HybridChatManager
+# - Add UI components
+# - Update tests
+
+# 3. Test thoroughly
+yarn test
+yarn build
+
+# 4. Test real-time features
+node yjs-websocket-server.js
+# Test in multiple browsers
+
+# 5. Update documentation
+# - Update this README.md
+# - Add inline code comments
+# - Update API documentation
+```
+
+### **Code Standards**
+
+#### **TypeScript Guidelines**
+- **Strict Types**: Always use proper TypeScript types, avoid `any`
+- **Interface First**: Define interfaces before implementation
+- **Error Handling**: Use `OperationResult<T>` for all async operations
+- **Null Safety**: Handle null/undefined cases explicitly
+
+#### **React Best Practices**
+- **Hooks**: Prefer hooks over class components
+- **Memoization**: Use `useMemo`/`useCallback` for expensive operations
+- **State Management**: Keep state as local as possible
+- **Error Boundaries**: Implement error boundaries for chat components
+
+#### **Testing Requirements**
+- **Unit Tests**: Test individual functions and providers
+- **Integration Tests**: Test provider interactions and data flow
+- **E2E Tests**: Test real-time synchronization across browsers
+- **Performance Tests**: Measure memory usage and WebSocket efficiency
+
+### **Architecture Decisions**
+
+#### **Provider Pattern**
+The provider pattern allows easy switching between storage backends:
+- **Benefits**: Clean abstraction, testability, extensibility
+- **Trade-offs**: Additional complexity, potential over-engineering
+- **Alternatives**: Direct implementation without abstraction
+
+#### **Yjs for Real-time Sync**
+Yjs provides conflict-free replicated data types (CRDTs):
+- **Benefits**: Automatic conflict resolution, offline support, mature library
+- **Trade-offs**: Learning curve, bundle size, WebSocket dependency
+- **Alternatives**: Socket.io with manual conflict resolution, OT algorithms
+
+#### **Hybrid Manager Approach**
+HybridChatManager coordinates multiple providers:
+- **Benefits**: Graceful degradation, mode switching, unified API
+- **Trade-offs**: Additional complexity, potential sync issues
+- **Alternatives**: Single provider with mode configuration
+
+### **Performance Guidelines**
+
+1. **Memory Management**: Always clean up subscriptions and observers
+2. **Network Efficiency**: Batch operations when possible
+3. **UI Responsiveness**: Use virtualization for large message lists
+4. **Error Recovery**: Implement reconnection and retry logic
+
+### **How Things Are Connected**
+
+#### **Data Flow Overview**
+```
+User Action (Send Message)
+    ↓
+ChatBoxComponent (React UI)
+    ↓
+useChatManager Hook
+    ↓
+HybridChatManager
+    ↓
+Active Provider (ALASql OR YjsPluvProvider)

+Storage Layer (IndexedDB OR WebSocket + Yjs)
+    ↓
+Real-time Updates
+    ↓
+Observer Callbacks
+    ↓
+React State Updates
+    ↓
+UI Re-render with New Message
+```
+
+#### **Component Integration Points**
+1. **Component Registration**: `src/comps/uiCompRegistry.ts` and `src/comps/index.tsx`
+2. **Event System**: Uses Lowcoder's event handling system for user interactions
+3. **Styling**: Integrates with Lowcoder's design system and theming
+4. **State Management**: Uses React hooks with proper cleanup
+
+#### **Real-time Synchronization Chain**
+1. **Message Sent**: User types and sends message
+2. **Local Update**: Immediate UI update (optimistic)
+3. **Provider Storage**: Message stored in active provider
+4. **WebSocket Broadcast**: If collaborative mode, sent to server
+5. **Remote Updates**: Other clients receive via WebSocket
+6. **Yjs Integration**: CRDT merge resolution if conflicts
+7. **Observer Triggers**: Yjs observers fire for remote changes
+8. **State Sync**: React state updated with remote messages
+9. **UI Update**: New messages appear in other browsers
