how to solve RTCIceServer.url is deprecated! Use urls instead ?

Question

i installed nodejs with soket.io. want to test this code to the server node server.js

var static = require('node-static');
var http = require('http');
// Create a node-static server instance listening on port 8181
var file = new(static.Server)();
// We use the http module’s createServer function and
// use our instance of node-static to serve the files
var app = http.createServer(function (req, res) {
file.serve(req, res);
}).listen(8181);
// Use socket.io JavaScript library for real-time web applications
var io = require('socket.io').listen(app);
// Let's start managing connections...
io.sockets.on('connection', function (socket){
// Handle 'message' messages
socket.on('message', function (message) {
log('S --> Got message: ', message);
socket.broadcast.to(message.channel).emit('message', \
message.message);
});
// Handle 'create or join' messages
socket.on('create or join', function (channel) {
var numClients = io.sockets.clients(channel).length;
console.log('numclients = ' + numClients);
// First client joining...
if (numClients == 0){
socket.join(channel);
socket.emit('created', channel);
// Second client joining...
} else if (numClients == 1) {
// Inform initiator...
io.sockets.in(channel).emit('remotePeerJoining', channel);
// Let the new peer join channel
socket.join(channel);
socket.broadcast.to(channel).emit('broadcast: joined', 'S --> \
broadcast(): client ' + socket.id + ' joined channel ' \
+ channel);
} else { // max two clients
console.log("Channel full!");
socket.emit('full', channel);
}
});
// Handle 'response' messages
socket.on('response', function (response) {
log('S --> Got response: ', response);
// Just forward message to the other peer
socket.broadcast.to(response.channel).emit('response',
response.message);
});
// Handle 'Bye' messages
socket.on('Bye', function(channel){
// Notify other peer
socket.broadcast.to(channel).emit('Bye');
// Close socket from server's side
socket.disconnect();
});
// Handle 'Ack' messages
socket.on('Ack', function () {
console.log('Got an Ack!');
// Close socket from server's side
socket.disconnect();
});
// Utility function used for remote logging
function log(){
var array = [">>> "];
for (var i = 0; i < arguments.length; i++) {
array.push(arguments[i]);
}
socket.emit('log', array);
}
});

and client.js

<script>

var socket = io.connect();

socket.emit('create or join', channel);

but when I do node server.js to prompt I have this error

and I get firefox

RTCIceServer.url is deprecated! Use urls instead.

how to solve ?

Answer 1

(I'm answering you subject, since the rest of your question seemed unrelated).

The Firefox web console warning "RTCIceServer.url is deprecated! Use urls instead" refers to your RTCPeerConnection configuration.

Locate code similar to this:

var pc = new RTCPeerConnection({ iceServers: [{ url: 'stun:foo.com:1234' }] });

and rename it to:

var pc = new RTCPeerConnection({ iceServers: [{ urls: 'stun:foo.com:1234' }] });
                                                   ^

The name changed, because each ice server may in fact have multiple ways (URLs) in which it can be located, depending on network topology.
