I'm trying to get the server or port of heroku;this works fine on the localhost, but the socket.io feature doesn't work on heroku.

this is the error i get on heroku.

websocket.js:120 WebSocket connection to
'wss://localhost:5000/socket.io/?EIO=3&transport=websocket' failed:
Error in connection establishment: net::ERR_CONNECTION_REFUSED
p.doOpen @ websocket.js:120

App.js

const express = require('express');

const bodyParser = require('body-parser');

const  app = express();

var http = require('http').Server(app);

var io = require('socket.io')(http);

var PORT = process.env.PORT || 5000;



if (process.env.NODE_ENV === 'production') {



  app.use(express.static('client/build'));



  app.get('*', (req, res) => {

    res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'));

  });

}



io.on('connection', (socket)=>{

    console.log(socket.id);



    socket.on('SEND_MESSAGE', (data)=>{

        io.emit('RECEIVE_MESSAGE', data);



    })





});



http.listen(PORT,function(){

  console.log('listening on port %s',PORT);

});

Chat.js

// this has to be something other than localhost, it needs to work vice versa.



this.socket = socketIOClient('localhost:5000');



this.socket.on('RECEIVE_MESSAGE', function(data){

    addMessage(data);

});

This is a hardcoded workaround

app.js

  this.socket = socketIOClient.connect(HEROKU_PATH_HERE, {secure: true});



   if(!this.socket){

        this.socket = socketIOClient('localhost:5000');

   }
