Local PeerJS Server disconnected after connected, and then connected again

[Laura Juo-Hsin Chen]

Hi, 

I succeed in using PeerJS with cloud server to make video conference thing, along with the websocket library ws. Now I tried to setup a local PeerJS Server, following the instruction from Combining with existing express app here, but things acted weirdly. Below are my codes:

-- Server --

//SET_UP

var express = require('express');

var app = express();

var ExpressPeerServer = require('peer').ExpressPeerServer;

var options = {

    debug: true

};

var http = require('http');

var server = http.createServer(app);

var port = process.env.PORT || 9000;

app.get('*', function(req, res){

res.sendFile(__dirname + req.url);

});

app.use('/peerjs', ExpressPeerServer(server, options));

server.listen(port);

//Websocket

var WebSocketServer = require('ws').Server;

var wss = new WebSocketServer( {'server': server} );

wss.on('connection', function(ws){

ws.on('message', function(data){

// ...

});

ws.on('close', function(){

// ...

});

});

-- Client --

peer = new Peer('123abc', { host: 'localhost', port: 9000, path:'/peerjs', debug:true});

// Get an ID from the PeerJS server

peer.on('open', function(id) {

console.log('My peer ID is: ' + id);

 

    // Now we can connect to the socket server

connectSocket();

});

And when I open the client side webpage http://localhost:9000/index.html, I got those information and error in console:

PeerJS:  Socket open

My peer ID is: 123abc

WebSocket connection to 'ws://localhost:9000/peerjs/peerjs?key=peerjs&id=123abc&token=i1nay3ueh3tprpb9' failed: Invalid frame header

PeerJS:  Socket closed.

PeerJS:  ERROR Error: Lost connection to server.

It seems the PeerJS socket was connected once but shortly disconnect after. Couldn't figure out why. 

Please advice with any ideas and feedback. Thanks!

Sorry about the Title, it's just Local PeerJS Server disconnected after connected. It didn't connect again. Sorry about the confused.

Solved it! Should create two servers for each websocket with different port.

My codes might not be efficient, but it works.

var express = require('express');
var app = express();

var http = require('http');
var server = http.createServer(app);

var port = process.env.PORT || 7000;

// peer_server

var ExpressPeerServer = require('peer').ExpressPeerServer;

var peerExpress = require('express');
var peerApp = peerExpress();
var peerServer = require('http').createServer(peerApp);

var options = { debug: true }

var peerPort = 9000;

app.get('*', function(req, res){
    res.sendFile(__dirname + req.url);
});

peerApp.use('/pp', ExpressPeerServer(peerServer, options));

server.listen(port);
peerServer.listen(peerPort);

Hi Laura,

thanks,

please can you help me?

in cloud9 ide i set up a new node.js application.

there i installed node npm install peer

so i added server like you suggested

//peerjs

var ExpressPeerServer = require('peer').ExpressPeerServer;

var peerExpress = require('express');

var peerApp = peerExpress();

var peerServer = require('http').createServer(peerApp);

var options = { debug: true }

var peerPort = 9000;

peerApp.use('/pp', ExpressPeerServer(peerServer, options));

peerServer.listen(peerPort);

and application is running here http://thron-collaboration-abioneperhobby.c9users.io/ so i created my peer object like this

new Peer(this.id, {host: 'thron-collaboration-abioneperhobby.c9users.io', port: 9000, secure:false, path: '/pp'});

but firefox cannot connect to the address ws://thron-collaboration-abioneperhobby.c9users.io:9000/pp/peerjs?key=peerjs&id=asd&token=kaety1y3pxd.
