3. upload the folder "myapp" to your site root   4. create server.js file with below content and save it to myapp:  

const express = require('express');
const { ExpressPeerServer } = require('peer');
const app = express();

app.enable('trust proxy');

const PORT = process.env.PORT;
const server = app.listen(PORT, () => {
  console.log(`App listening on port ${PORT}`);
  console.log('Press Ctrl+C to quit.');

        <httpPlatform processPath="node" arguments="server.js" startupTimeLimit="20" startupRetryCount="2" stdoutLogEnabled="false" stdoutLogFile="./log.txt">
            <environmentVariables>
                <environmentVariable name="PORT" value="%HTTP_PLATFORM_PORT%" />
