Hi how does this work?

and what apps do l need ....

What are the commands to run for it to work/ run.

I got the project up. But in no way could I bind another person. It always shows this error :
peerjs.min.js:64 GET http://localhost:443/peerjs/peerjs/id?ts=15988980531990.30612093669879203 net::ERR_CONNECTION_REFUSED

Could anyone help? @Nazariy995 @CleverProgrammer @ykhedher

For me it did worked while I opened the same link in two tabs which means it works perfectly while attendees are in same network. But once I shared this to my friend who stays around 1km distance which is WAN I guess, we do get connected (I can see the black blank box for video ) but audio and video is not connected. Also, we can send text messages in real-time in the app but audio/video connection is not successful. I do get a black window when the new user enters but its completely black and I am sure that it's not an internet problem (audio / video both feature not working but text messaging working if both the parties belongs to different network). I tried to look for audio/video constraints in console and it shows empty which means the connection isn't successful, while for google meet session , google meet's audio and video constraints are visible. Please help me with this and thanks for your time.

Hi,

Hi, I tried running this on my server <video.example.com> and created an nginx reverse proxy.

However, I am getting this error in the console.

Firefox can't establish a connection to the server at wss://video.example.com/socket.io/?EIO=3&transport=websocket&sid=CqM_U7hMStz1Qw3gAAAA.
Firefox can't establish a connection to the server at wss://video.example.com/peerjs/peerjs?key=peerjs&id=8c4cc4ef-5843-4407-98f6-ebc75ff699b9&token=qmq9ep06q9j.

The nginx config looks like this:

server {
  server_name video.example.com;

  location / {
    proxy_pass http://localhost:3030;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

Any idea how this can be fixed?

The project runs completely well. My only issue is trying to do screenshare using peer js . I tried changing the media stream of the webcam video stream to my screen share video stream. But then the video just freezes in the peer connected to my room. It would be of great help if someone could manage to do swap the video mediaStream while our video stream is being transmitted to all the peers connected to us. Thanks again.

What do I need to do in order to run it locally on my machine? Also, what is needed for me to be able to connect to it using another device? I tried running the server and typing my IP address:3030, but there was still just one video frame on the screen.
I'd be grateful if someone could help me.

i am following their tutorial at this point https://youtu.be/ZVznzY7EjuY?t=6023

Before that, everything worked perfectly, but i can not answer the call when new user join room and their is no new video tag appended in the video grid.

This is my server.js

const express = require('express')
const app = express()
const server = require('http').Server(app)
const io = require('socket.io')(server)
const { v4: uuidv4 } = require('uuid')
const { ExpressPeerServer } = require('peer')
const peerServer = ExpressPeerServer(server, {
  debug: true
})

app.set('view engine', 'ejs')
app.use(express.static('public'))

app.use("/peerjs", peerServer)
app.get('/', (req, res) => {
  res.redirect(`/${uuidv4()}`)
})

app.get('/:room', (req, res) => {
  res.render('room', { roomId: req.params.roomId })
})

io.on('connection', socket => {
  socket.on('join-room', (roomId, userId) => {
    socket.join(roomId)
    socket.to(roomId).broadcast.emit('user-connected', userId)
  })
})

server.listen(3030)

this is my script.js

const socket = io('/')
const videoGrid = document.getElementById('video-grid')
const myVideo = document.createElement('video')
myVideo.muted = true

var peer = new Peer(undefined, {
  path: '/peerjs',
  host: '/',
  port: '3030'
})

let myVideoStream

navigator.mediaDevices
  .getUserMedia({
    video: true,
    audio: true
  })
  .then(stream => {
    myVideoStream = stream
    addVideoStream(myVideo, stream)

    socket.on('user-connected', userId => {
      connectToNewUser(userId, stream)
    })

    peer.on('call', call => {
      call.answer(stream)
      const video = document.createElement('video')
      call.on('stream', userVideoStream => {
        addVideoStream(video, userVideoStream)
      })
    })
  })

peer.on('open', id => {
  socket.emit('join-room', ROOM_ID, id)
})

function connectToNewUser (userId, stream) {
  const call = peer.call(userId, stream)
  const video = document.createElement('video')
  call.on('stream', userVideoStream => {
    addVideoStream(video, userVideoStream)
  })
}

function addVideoStream (video, stream) {
  video.srcObject = stream
  video.addEventListener('loadedmetadata', () => {
    video.play()
  })
  videoGrid.append(video)
}

as i tried to console.log(userMediaStream) it returned nothing in this code block

   peer.on('call', call => {
      call.answer(stream)
      const video = document.createElement('video')
      call.on('stream', userVideoStream => {
        addVideoStream(video, userVideoStream)
      })
    })

i dont know how to deal with it, please tell me why, thank you so much 👍

i am trying to add screen share in present code .. but it shows on my screen clearly but unable to see on other user screen
code :-

       navigator.mediaDevices.getDisplayMedia({
           video: true, 
           audio:true
       }).then(stream => {
           const video1 = document.createElement('video');
           video1.controls = true;
           addVideoStream(video1,stream)

           
       socket.on('user-connected', userId =>{
           const call = peer.call(userId, stream)
           stream.getVideoTracks()[0].addEventListener('ended', () => {
               video1.remove()
             });
           call.on('close', () => {

           })  
       })
           stream.getVideoTracks()[0].addEventListener('ended', () => {
             video1.remove()
           });
         });
       }catch(err) {
           console.log("Error: " + err);
       }
