Modern business environments increasingly require integrated solutions that support diverse technological requirements simultaneously. From network infrastructure to security systems, professional IT structured cabling combined with reliable power protection creates the foundation for comprehensive operational capability that adapts to changing business needs.

IV. Implementation Strategies for Singapore Organizations

Successful deployment of integrated cabling and UPS solutions requires careful assessment of organizational requirements and strategic planning for both current and future needs. This includes consideration of various facility types and operational requirements, from traditional commercial spaces to specialized developments such as Faber Residence projects that demand sophisticated infrastructure integration.

Organizations must partner with experienced providers who understand the complexities of designing systems that accommodate both structured cabling and power protection requirements. Professional implementation ensures that these technologies work together effectively, creating infrastructure that provides reliable performance, scalability, and comprehensive protection for critical business operations.

The strategic investment in quality structured cabling and UPS systems represents a fundamental commitment to operational excellence and business continuity. In Singapore's competitive business environment, these technologies provide the reliable foundation necessary for sustained success, ensuring seamless connectivity and comprehensive protection that enables organizations to focus on core business objectives rather than infrastructure concerns.

try using this code do you think it will work?

Below is a minimal example of how you can add a real‐time chat box that only your authenticated users can use. It uses:

• Node.js + Express for the web server
• express‐session to track logged-in users
• Socket.io for real-time messaging

You’ll need to adapt the authentication check to however you store your users (database, JWTs, etc.), but this will give you the core of “only logged‐in folks see/use the chat.”

---

1. Install dependencies

npm init -y
npm install express express-session socket.io

---

2. server.js

const express = require('express');
const http    = require('http');
const session = require('express-session');
const SocketIO = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = new SocketIO(server);

// 1) Session middleware
const sessionMiddleware = session({
  secret: 'YOUR_SESSION_SECRET',
  resave: false,
  saveUninitialized: false,
  // store: you can add a store like connect-mongo here
});
app.use(sessionMiddleware);

// 2) Make session available in socket.handshake
io.use((socket, next) => {
  sessionMiddleware(socket.request, socket.request.res || {}, next);
});

// Serve static files (our chat page + JS)
app.use(express.static('public'));

// 3) A simple “login” route for demo purposes.
//    In real life you’d check a DB, hash passwords, etc.
app.get('/login', (req, res) => {
  // e.g. ?user=alice
  const username = req.query.user;
  if (!username) return res.sendStatus(400);
  req.session.user = { name: username };
  res.redirect('/chat.html');
});

// 4) Protect chat page
app.get('/chat.html', (req, res, next) => {
  if (!req.session.user) return res.redirect('/login.html');
  next();
});

// 5) Handle socket connections
io.on('connection', socket => {
  const req = socket.request;
  if (!req.session.user) {
    // kick out any un‐authenticated socket
    return socket.disconnect(true);
  }

  const user = req.session.user.name;
  socket.broadcast.emit('message', {
    from: 'SYSTEM',
    text: `${user} has joined the chat`
  });

  socket.on('message', msg => {
    io.emit('message', {
      from: user,
      text: msg
    });
  });

  socket.on('disconnect', () => {
    socket.broadcast.emit('message', {
      from: 'SYSTEM',
      text: `${user} has left the chat`
    });
  });
});

server.listen(3000, () => {
  console.log('Listening on http://localhost:3000/');
});

3. public/chat.html

```html

Chat Room

> Send>

> const socket = io(); > > const form = document.getElementById('form'); > const input = document.getElementById('input'); > const messages = document.getElementById('messages'); > > socket.on('message', msg => { > const li = document.createElement('li'); > li.textContent = `${msg.from}: ${msg.text}`; > messages.appendChild(li); > messages.scrollTop = messages.scrollHeight; > }); > > form.addEventListener('submit', e => { > e.preventDefault(); > if (input.value.trim()) { > socket.emit('message', input.value); > input.value = ''; > } > }); >

```

4. How It Works

1. Session setup
   We use express-session so that when a user “logs in” (e.g. via your existing form/database), we store { user: { name: '…' } } in req.session.
2. Socket authentication
   By re-using the same session middleware in Socket.io’s io.use(…), every incoming socket has access to socket.request.session. If there’s no session.user, we immediately disconnect() them.
3. Real-time chat

• On connect/disconnect we broadcast a system message.
• On client‐side, every message the user sends is emitted and broadcast to all.

1. Protecting the page
   We guard chat.html in Express so that if you go there directly, you’ll get bounced to /login.html (you’d build a real login page).

---

Next Steps

• Integrate with your real user database. Replace the demo /login route with your own logic.
• Persist chat history if you want to store messages (e.g. in MongoDB or MySQL).
• Add rooms or private messaging by namespace or room support in Socket.io.
• Style it and embed it in your existing layout (lemm.ee) CSS.
