Socket.io over Node.js / Demo
socket.io over node.js for webrtc-signaling!
server.js
file
This is the file that I was running on https://webrtcweb.com:9559/
. I'll recommend to modify and use this file.
npm install socketio-over-nodejs
How to use?
In ui.js
files you can find openSocket
method; or in all libraries; you can find openSignalingChannel
method.
var SIGNALING_SERVER = 'https://socketio-over-nodejs2.herokuapp.com:443/';
connection.openSignalingChannel = function(config) {
var channel = config.channel || this.channel || 'default-namespace';
var sender = Math.round(Math.random() * 9999999999) + 9999999999;
io.connect(SIGNALING_SERVER).emit('new-channel', {
channel: channel,
sender : sender
});
var socket = io.connect(SIGNALING_SERVER + channel);
socket.channel = channel;
socket.on('connect', function () {
if (config.callback) config.callback(socket);
});
socket.send = function (message) {
socket.emit('message', {
sender: sender,
data : message
});
};
socket.on('message', config.onmessage);
};
io.connect(URL).emit('new-channel')
starts a new namespace that is used privately or publicly to transmit/exchange appropriate stuff e.g. room-details, participation-requests, SDP, ICE, etc.
openSocket
var config = {
openSocket: function (config) {
var SIGNALING_SERVER = 'https://socketio-over-nodejs2.herokuapp.com:443/';
config.channel = config.channel || location.href.replace(/\/|:|#|%|\.|\[|\]/g, '');
var sender = Math.round(Math.random() * 999999999) + 999999999;
io.connect(SIGNALING_SERVER).emit('new-channel', {
channel: config.channel,
sender: sender
});
var socket = io.connect(SIGNALING_SERVER + config.channel);
socket.channel = config.channel;
socket.on('connect', function () {
if (config.callback) config.callback(socket);
});
socket.send = function (message) {
socket.emit('message', {
sender: sender,
data: message
});
};
socket.on('message', config.onmessage);
}
};
Presence Detection
You can detect presence of a room like this:
var SIGNALING_SERVER = 'https://socketio-over-nodejs2.herokuapp.com:443/';
function testChannelPresence(channel) {
var socket = io.connect(SIGNALING_SERVER);
socket.on('presence', function (isChannelPresent) {
console.log('is channel present', isChannelPresent);
if (!isChannelPresent) startNewSession();
});
socket.emit('presence', channel);
}
// test whether default channel already created or not!
testChannelPresence('default-channel');
