Step 4: Set Up WebSocket Server

4.1 Create WebSocket Service

Create src/services/websocket.service.ts:

import { Injectable } from '@nestjs/common';
import { Server, Socket } from 'socket.io';
import { JwtService } from '@nestjs/jwt';
import { UserService } from '../modules/user/user.service';

@Injectable()
export class WebSocketService {
  private io: Server;
  private connectedUsers = new Map<string, Socket>();

  constructor(
    private jwtService: JwtService,
    private userService: UserService
  ) {}

  setServer(server: Server) {
    this.io = server;
    this.setupEventHandlers();
  }

  private setupEventHandlers() {
    this.io.use(async (socket, next) => {
      try {
        const token = socket.handshake.auth.token;
        const payload = this.jwtService.verify(token);
        const user = await this.userService.findById(payload.sub);
        
        if (!user) throw new Error('User not found');
        
        socket.data.user = user;
        next();
      } catch (error) {
        next(new Error('Authentication failed'));
      }
    });

    this.io.on('connection', (socket) => {
      this.handleConnection(socket);
    });
  }

  private async handleConnection(socket: Socket) {
    const user = socket.data.user;
    
    // Store connection
    this.connectedUsers.set(user.id, socket);
    
    // Update user status
    await this.userService.update(user.id, {
      isOnline: true,
      status: 'ONLINE',
      socketId: socket.id
    });

    // Join user to their rooms
    const userRooms = await this.getUserRooms(user.id);
    userRooms.forEach(room => {
      socket.join(`room:${room.id}`);
    });

    // Broadcast user online status
    this.broadcastUserStatus(user.id, 'ONLINE');

    // Handle events
    this.setupSocketEvents(socket);

    // Handle disconnect

    });

    socket.on('room:leave', (roomId) => {
      this.handleLeaveRoom(socket, roomId);
    });

    // Document collaboration events
    socket.on('document:edit', (data) => {
      this.handleDocumentEdit(socket, data);
    });

    socket.on('document:cursor', (data) => {
      this.handleCursorUpdate(socket, data);
    });

    // Presence events
    socket.on('status:update', (status) => {
      this.handleStatusUpdate(socket, status);
    });
  }

  private async handleDisconnect(socket: Socket) {
    const user = socket.data.user;
    
    // Remove connection
    this.connectedUsers.delete(user.id);
    
    // Update user status
    await this.userService.update(user.id, {
      isOnline: false,
      status: 'OFFLINE',
      lastSeen: new Date(),
      socketId: null
    });

    // Broadcast user offline status
    this.broadcastUserStatus(user.id, 'OFFLINE');
  }

  // Event handlers
  private async handleSendMessage(socket: Socket, data: any) {
    const user = socket.data.user;
    const { roomId, content, type = 'TEXT', replyToId } = data;

    try {
      // Create message in database
      const message = await this.messageService.create({
        content,
        type,
        senderId: user.id,
        roomId,
        replyToId
      });

      // Broadcast to room
      this.io.to(`room:${roomId}`).emit('message:new', {
        ...message,
        sender: {
          id: user.id,
          username: user.username,
          avatar: user.avatar

    }
  }

  private handleTyping(socket: Socket, data: any) {

    });
  }

  private async handleDocumentEdit(socket: Socket, data: any) {
    const user = socket.data.user;
    const { documentId, operation, version } = data;

    try {
      // Apply operation to document
      const updatedDocument = await this.documentService.applyOperation(
        documentId,
        operation,
        version,
        user.id
      );

    }
  }

  // Utility methods
  public broadcastToRoom(roomId: string, event: string, data: any) {
    this.io.to(`room:${roomId}`).emit(event, data);

    }
  }

  public broadcastUserStatus(userId: string, status: string) {
    this.io.emit('user:status', { userId, status });
  }

  public getConnectedUsers(): string[] {
    return Array.from(this.connectedUsers.keys());
  }
}

4.2 Initialize WebSocket in Main App

Update src/app.ts:

import { createServer } from 'http';
import { Server } from 'socket.io';
import { WebSocketService } from './services/websocket.service';

// After creating Express app
const server = createServer(app);

const io = new Server(server, {
  cors: {
    origin: process.env.CLIENT_URL || "http://localhost:3000",
    methods: ["GET", "POST"]
  }
});

// Initialize WebSocket service
const webSocketService = container.resolve(WebSocketService);
webSocketService.setServer(io);

// Start server
const PORT = process.env.PORT || 3000;
server.listen(PORT, () => {
  console.log(`🚀 Server running on port ${PORT}`);
  console.log(`📡 WebSocket server ready`);
});

Step 5: Implement Real-time Chat

5.1 Enhanced Message Service

Update src/modules/message/message.service.ts:

// Add these methods to MessageService

async getRecentMessages(roomId: string, limit = 50) {
  return this.messageRepository.findMany({
    where: { 
      roomId,
      deletedAt: null 
    },
    include: {
      sender: {
        select: { id: true, username: true, avatar: true }
      },
      replyTo: {
        include: {
          sender: {
            select: { username: true }
          }
        }
      }
    },
    orderBy: { createdAt: 'desc' },
    take: limit
  });
}

async markAsRead(roomId: string, userId: string) {
  // Update last read timestamp for user in room
  await this.roomMemberRepository.updateMany({
    where: { roomId, userId },
    data: { lastReadAt: new Date() }
  });
}

async getUnreadCount(roomId: string, userId: string) {
  const member = await this.roomMemberRepository.findFirst({
    where: { roomId, userId }
  });

  if (!member) return 0;

  return this.messageRepository.count({
    where: {
      roomId,
      createdAt: { gt: member.lastReadAt || member.joinedAt },
      senderId: { not: userId }
    }
  });
}

5.2 Create Chat Controller

Create src/modules/chat/chat.controller.ts:

import { Controller, Get, Post, Body, Param, Query, UseGuards } from '@nestjs/common';
import { JwtAuthGuard } from '../auth/jwt-auth.guard';
import { CurrentUser } from '../auth/current-user.decorator';
import { ChatService } from './chat.service';

@Controller('api/v1/chat')
@UseGuards(JwtAuthGuard)
export class ChatController {
  constructor(private chatService: ChatService) {}

  @Get('rooms')
  async getUserRooms(@CurrentUser() user: any) {
    return this.chatService.getUserRooms(user.id);
  }

  @Post('rooms')
  async createRoom(@CurrentUser() user: any, @Body() data: any) {
    return this.chatService.createRoom(user.id, data);
  }

  @Get('rooms/:roomId/messages')
  async getRoomMessages(
    @Param('roomId') roomId: string,
    @Query('limit') limit?: number,
    @Query('before') before?: string
  ) {
    return this.chatService.getRoomMessages(roomId, { limit, before });
  }

  @Post('rooms/:roomId/join')
  async joinRoom(@CurrentUser() user: any, @Param('roomId') roomId: string) {
    return this.chatService.joinRoom(roomId, user.id);
  }

  @Post('rooms/:roomId/read')
  async markAsRead(@CurrentUser() user: any, @Param('roomId') roomId: string) {
    return this.chatService.markAsRead(roomId, user.id);
  }
}

Step 6: Add Live Dashboard

6.1 Create Analytics Service

Create src/modules/analytics/realtime-analytics.service.ts:

import { Injectable } from '@nestjs/common';
import { WebSocketService } from '../../services/websocket.service';
import { Cron, CronExpression } from '@nestjs/schedule';

@Injectable()
export class RealtimeAnalyticsService {
  constructor(private webSocketService: WebSocketService) {}

  @Cron(CronExpression.EVERY_10_SECONDS)
  async broadcastLiveMetrics() {
    const metrics = await this.getLiveMetrics();
    this.webSocketService.io.to('dashboard').emit('metrics:update', metrics);
  }

  private async getLiveMetrics() {
    const connectedUsers = this.webSocketService.getConnectedUsers().length;
    const activeRooms = await this.getActiveRoomsCount();
    const messagesLastHour = await this.getMessagesLastHour();
    const systemLoad = await this.getSystemMetrics();

    return {
      connectedUsers,
      activeRooms,
      messagesLastHour,
      systemLoad,
      timestamp: new Date()
    };
  }

  async getActiveRoomsCount() {
    // Count rooms with recent activity
    const oneHourAgo = new Date(Date.now() - 60 * 60 * 1000);
    return this.messageRepository.count({
      where: {
        createdAt: { gte: oneHourAgo }
      },
      distinct: ['roomId']
    });
  }

  async getMessagesLastHour() {
    const oneHourAgo = new Date(Date.now() - 60 * 60 * 1000);
    return this.messageRepository.count({
      where: {
        createdAt: { gte: oneHourAgo }
      }
    });
  }

  async getSystemMetrics() {
    const memoryUsage = process.memoryUsage();
    const cpuUsage = process.cpuUsage();
    
    return {
      memory: {
        used: memoryUsage.heapUsed,
        total: memoryUsage.heapTotal,
        percentage: (memoryUsage.heapUsed / memoryUsage.heapTotal) * 100
      },
      cpu: {
        user: cpuUsage.user,
        system: cpuUsage.system
      },
      uptime: process.uptime()
    };
  }
}

6.2 Dashboard WebSocket Events

Add dashboard-specific events to your WebSocket service:

// Add to WebSocketService

private setupDashboardEvents(socket: Socket) {
  socket.on('dashboard:subscribe', () => {
    socket.join('dashboard');
    // Send initial metrics
    this.sendDashboardMetrics(socket);
  });

  socket.on('dashboard:unsubscribe', () => {
    socket.leave('dashboard');
  });
}

private async sendDashboardMetrics(socket: Socket) {
  const metrics = await this.realtimeAnalyticsService.getLiveMetrics();
  socket.emit('metrics:initial', metrics);
}

Step 7: Implement Collaborative Editing

7.1 Document Service with Operational Transform

Create src/modules/document/document-collaboration.service.ts:

import { Injectable } from '@nestjs/common';
import { DocumentService } from './document.service';
import { WebSocketService } from '../../services/websocket.service';

@Injectable()
export class DocumentCollaborationService {
  constructor(
    private documentService: DocumentService,
    private webSocketService: WebSocketService
  ) {}

  async applyOperation(documentId: string, operation: any, version: number, userId: string) {
    const document = await this.documentService.findById(documentId);
    
    if (!document) {
      throw new Error('Document not found');
    }

    if (document.version !== version) {
      // Version conflict - need to transform operation
      const transformedOperation = await this.transformOperation(
        documentId, 
        operation, 
        version, 
        document.version
      );
      operation = transformedOperation;
    }

    // Apply operation to document content
    const newContent = this.applyOperationToContent(document.content, operation);
    const newVersion = document.version + 1;

    // Update document
    const updatedDocument = await this.documentService.update(documentId, {
      content: newContent,
      version: newVersion,
      lastEditedBy: userId
    });

    // Save operation to history
    await this.documentEditService.create({
      documentId,
      userId,
      operation,
      version: newVersion
    });

    return updatedDocument;
  }

  private async transformOperation(documentId: string, operation: any, fromVersion: number, toVersion: number) {
    // Get all operations between versions
    const operations = await this.documentEditService.findMany({
      where: {
        documentId,
        version: { gt: fromVersion, lte: toVersion }
      },
      orderBy: { version: 'asc' }
    });

    // Apply operational transform
    let transformedOp = operation;
    for (const op of operations) {
      transformedOp = this.transform(transformedOp, op.operation);
    }

    return transformedOp;
  }

  private transform(op1: any, op2: any) {
    // Simplified operational transform
    // In production, use a library like ShareJS or Yjs
    
    if (op1.type === 'insert' && op2.type === 'insert') {
      if (op1.position <= op2.position) {
        return op1;
      } else {
        return {
          ...op1,
          position: op1.position + op2.text.length
        };
      }
    }

    if (op1.type === 'delete' && op2.type === 'insert') {
      if (op1.position < op2.position) {
        return op1;
      } else {
        return {
          ...op1,
          position: op1.position + op2.text.length
        };
      }
    }

    // Add more transformation rules as needed
    return op1;
  }

  private applyOperationToContent(content: string, operation: any) {
    switch (operation.type) {
      case 'insert':
        return content.slice(0, operation.position) + 
               operation.text + 
               content.slice(operation.position);
      
      case 'delete':
        return content.slice(0, operation.position) + 
               content.slice(operation.position + operation.length);
      
      case 'retain':
        return content;
      
      default:
        throw new Error(`Unknown operation type: ${operation.type}`);
    }
  }
}

Step 8: Add Push Notifications

8.1 Notification Service

Create src/modules/notification/notification.service.ts:

import { Injectable } from '@nestjs/common';
import { WebSocketService } from '../../services/websocket.service';
import { EmailService } from '../email/email.service';

@Injectable()
export class NotificationService {
  constructor(
    private webSocketService: WebSocketService,
    private emailService: EmailService,
    private notificationRepository: NotificationRepository
  ) {}

  async sendNotification(userId: string, notification: CreateNotificationDto) {
    // Save to database
    const savedNotification = await this.notificationRepository.create({
      userId,
      ...notification
    });

    // Send real-time notification if user is online
    this.webSocketService.sendToUser(userId, 'notification:new', savedNotification);

    // Send email for important notifications if user is offline
    const user = await this.userService.findById(userId);
    if (!user.isOnline && notification.type === 'IMPORTANT') {
      await this.emailService.sendNotificationEmail(user.email, notification);
    }

    return savedNotification;
  }

  async sendBulkNotification(userIds: string[], notification: CreateNotificationDto) {
    const notifications = await Promise.all(
      userIds.map(userId => this.sendNotification(userId, notification))
    );

    return notifications;
  }

  async markAsRead(notificationId: string, userId: string) {
    const notification = await this.notificationRepository.update(notificationId, {
      isRead: true,
      readAt: new Date()
    });

    // Notify client of read status change
    this.webSocketService.sendToUser(userId, 'notification:read', {
      notificationId,
      isRead: true
    });

    return notification;
  }

  async getUnreadCount(userId: string) {
    return this.notificationRepository.count({
      where: { userId, isRead: false }
    });
  }
}

Step 9: Test Real-time Features

9.1 Test Chat System

# Create a chat room
curl -X POST http://localhost:3000/api/v1/chat/rooms \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "General Chat",
    "description": "General discussion room",
    "type": "PUBLIC"
  }'

# Join the room
curl -X POST http://localhost:3000/api/v1/chat/rooms/ROOM_ID/join \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"

# Get room messages
curl http://localhost:3000/api/v1/chat/rooms/ROOM_ID/messages \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"

9.2 Test WebSocket Connection

Create a simple client test file test-websocket.js:

const io = require('socket.io-client');

const socket = io('http://localhost:3000', {
  auth: {
    token: 'YOUR_JWT_TOKEN_HERE'
  }
});

socket.on('connect', () => {
  console.log('✅ Connected to WebSocket server');
  
  // Test sending a message
  socket.emit('message:send', {
    roomId: 'ROOM_ID_HERE',
    content: 'Hello from WebSocket client!',
    type: 'TEXT'
  });
});

socket.on('message:new', (message) => {
  console.log('📨 New message:', message);
});

socket.on('user:typing', (data) => {
  console.log('⌨️ User typing:', data);
});

socket.on('notification:new', (notification) => {
  console.log('🔔 New notification:', notification);
});

socket.on('disconnect', () => {
  console.log('❌ Disconnected from server');
});

# Run the WebSocket test
node test-websocket.js

9.3 Test Document Collaboration

# Create a document
curl -X POST http://localhost:3000/api/v1/documents \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Collaborative Document",
    "content": "Initial content",
    "isPublic": true
  }'

# Test document editing via WebSocket
# (Use the WebSocket client to emit document:edit events)

Step 10: Performance Optimization

10.1 Add Redis for Scaling

# Configure Redis adapter for WebSocket scaling
npm install @socket.io/redis-adapter redis

Update WebSocket service for Redis:

import { createAdapter } from '@socket.io/redis-adapter';
import { createClient } from 'redis';

// In WebSocketService.setServer()
if (process.env.REDIS_URL) {
  const pubClient = createClient({ url: process.env.REDIS_URL });
  const subClient = pubClient.duplicate();

  await Promise.all([pubClient.connect(), subClient.connect()]);

  this.io.adapter(createAdapter(pubClient, subClient));
  console.log('📡 WebSocket Redis adapter configured');
}

10.2 Add Rate Limiting

// Add to WebSocket service
private rateLimitMap = new Map<string, number[]>();

private checkRateLimit(userId: string, maxRequests = 10, windowMs = 60000): boolean {
  const now = Date.now();
  const userRequests = this.rateLimitMap.get(userId) || [];
  
  // Remove old requests outside the window
  const validRequests = userRequests.filter(time => now - time < windowMs);
  
  if (validRequests.length >= maxRequests) {
    return false; // Rate limit exceeded
  }
  
  validRequests.push(now);
  this.rateLimitMap.set(userId, validRequests);
  return true;
}

// Use in event handlers
private async handleSendMessage(socket: Socket, data: any) {
  const user = socket.data.user;
  
  if (!this.checkRateLimit(user.id)) {
    socket.emit('error', { message: 'Rate limit exceeded' });
    return;
  }
  
  // ... rest of message handling
}

Step 11: Deploy Real-time Features

11.1 Production Configuration

Update your production environment:

# WebSocket Configuration
WEBSOCKET_CORS_ORIGIN=https://your-frontend-domain.com
WEBSOCKET_TRANSPORTS=websocket,polling

# Redis for scaling
REDIS_URL=redis://your-redis-server:6379

# Rate limiting
RATE_LIMIT_WINDOW=60000
RATE_LIMIT_MAX_REQUESTS=100

11.2 Load Balancer Configuration

For multiple server instances, configure sticky sessions:

# nginx.conf
upstream websocket_backend {
    ip_hash; # Enable sticky sessions
    server app1:3000;
    server app2:3000;
    server app3:3000;
}

server {
    location /socket.io/ {
        proxy_pass http://websocket_backend;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}
