THEN Move notification timers from server creation to start only after a client connects to the SSE endpoint. In the server setup, use an event listener for the 'connect' event to begin sending periodic messages, ensuring that the server does not attempt to send notifications before any client is connected.

// Instead of starting intervals immediately:
// server.setInterval(...);
// Use this pattern:
const notificationIntervals = [];
app.on('connect', () => {
  notificationIntervals.push(setInterval(() => { sendNotification(); }, 5000));
});
app.on('disconnect', () => {
  notificationIntervals.forEach(clearInterval);
});
