QvA Hub LAN - DEMO

This demo illustrates functionality of Qva Hub LAN, Monitor and Core client operations

Overview

QvA Hub LAN is a Node.js server application that manages local network connections between QvA applications. Over HTTP the monitor app is ran, and can only be requested on the server LAN IP. Over WebSocket interaction communication the Hub does WebRTC signalling for the establishment of Peer to Peer connections between devices and apps. A demo is created using the core client code simulating devices and P2P connecting them, the demo can also only be ran on the actual server.

Features

• WebSocket server for client connections
• WebRTC signaling server
• Built-in monitoring dashboard
• Multi-client support
• Automatic LAN discovery
• Port management (default: 52330)
• Monitor connections in your LAN

Installation

You need the QvA Hub LAN server running for the demo simulating connections can work :

git clone https://github.com/QueasovanAlles/qva-hub-lan.git
cd qva-hub-lan
node server --port 52330

and in another terminal :

git clone https://github.com/QueasovanAlles/qva-hub-lan-demo.git
cd qva-hub-lan-demo
ng serve --port 52401

then browse to : localhost:52404

Dependencies

• Node.js 18+
• ws: ^8.0.0
• express: ^4.18.0
• qva-hub-lan-monitor: ^1.0.0 (included)

Usage

# Start the hub
npm start

# Access monitor interface
http://<server LAN IPv4>:52330

Configuration

Just running the server and watching the monitor which will show nothing happening :

node server --port 52330

This is configuration of QvATPC terminals for full test, demonstrating all aspects as seperated apps :
