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')
app.set('view engine', 'ejs')
app.use(express.static('public'))
app.get('/', (req, res) => {
res.redirect(`/${uuidV4()}`)
})
app.get('/:room', (req, res) => {
res.render('room', { roomId: req.params.room })
})
io.on('connection', socket => {
socket.on('join-room', (roomId, userId) => {
console.log(roomId +"/"+ userId +"wowowowow")
socket.join(roomId)
console.log(roomId + userId)
// socket.to(roomId).broadcast.emit('user-connected', userId)
socket.broadcast.to(roomId).emit('user-connected', userId)
socket.on('disconnect', () => {
// socket.to(roomId).broadcast.emit('user-disconnected', userId)
socket.broadcast.to(roomId).emit('user-disconnected', userId)
})
})
})
server.listen(3000)
script.js
const socket = io('/')
const videoGrid = document.getElementById('video-grid')
const myPeer = new Peer(undefined, { host: "peerjs-server.herokuapp.com", secure: true, port: 443, });
const myVideo = document.createElement('video')
myVideo.muted = true
const peers = {}
navigator.mediaDevices.getUserMedia({
video: true,
audio: true
}).then(stream => {
addVideoStream(myVideo, stream)
myPeer.on('call', call => {
call.answer(stream)
const video = document.createElement('video')
call.on('stream', userVideoStream => {
addVideoStream(video, userVideoStream)
})
})
socket.on('user-connected', userId => {
connectToNewUser(userId, stream)
})
})
socket.on('user-disconnected', userId => {
if (peers[userId]) peers[userId].close()
})
myPeer.on('open', id => {
socket.emit('join-room', ROOM_ID, id)
})
function connectToNewUser(userId, stream) {
const call = myPeer.call(userId, stream)
const video = document.createElement('video')
call.on('stream', userVideoStream => {
addVideoStream(video, userVideoStream)
})
call.on('close', () => {
