Queue Display App

Digital Queue Display System built with:

• Svelte 5
• SvelteKit
• Tailwind CSS v4
• Socket.io client (optional backend connection)

Quick Start

npm install
npm run dev

Open:

• http://localhost:5173/display
• http://localhost:5173/operator
• http://localhost:5173/admin
• http://localhost:5173/queue/take

Demo Credentials

• Operator (per loket):
  • op-loket-1 / queue123 / PIN 1001
  • op-loket-2 / queue123 / PIN 1002
  • op-loket-3 / queue123 / PIN 1003
  • op-loket-4 / queue123 / PIN 1004
  • op-loket-5 / queue123 / PIN 1005

Optional secure operator route:

• http://localhost:5173/operator/loket-3 (locks login flow to loket 3)

Real-time Mode

By default, real-time updates work via browser BroadcastChannel (cross-tab).

If you have a backend websocket/socket.io server, set:

PUBLIC_SOCKET_URL=http://localhost:8081
PUBLIC_SOCKET_NAMESPACE=/queue
PUBLIC_SOCKET_BRANCH=main

The display will show reconnecting status and retry every 3 seconds when disconnected.

For the paired queue-socket service in this workspace, run the Go server on :8081.
