WebSocket over Node.js / Demo

npm downloads

Install

npm install websocket-over-nodejs
cd node_modules/websocket-over-nodejs
node server.js

Now open https://localhost:9449/ or use this wss://localhost.com:9449/.

How to use?

openSocket is used in all standalone WebRTC Experiments. You can define this method in your ui.js file or in your HTML page.

var SIGNALING_SERVER = 'wss://localhost.com:9449/';
var config = {
    openSocket = function (config) {
        config.channel = config.channel || 'main-public-channel';
 
        var websocket = new WebSocket(SIGNALING_SERVER);
        websocket.channel = config.channel;
        websocket.onopen = function () {
            websocket.push(JSON.stringify({
                open: true,
                channel: config.channel
            }));
            if (config.callback)
                config.callback(websocket);
        };
 
        websocket.onmessage = function (event) {
            config.onmessage(JSON.parse(event.data));
        };
 
        websocket.push = websocket.send;
        websocket.send = function (data) {
            websocket.push(JSON.stringify({
                data: data,
                channel: config.channel
            }));
        };
    }
};

Presence Detection

You can detect presence of any channel/room; and invoke open/join methods accordingly!

// use "channel" as sessionid or use custom sessionid!
var roomid = connection.channel;
 
var SIGNALING_SERVER = 'wss://localhost.com:9449/';
var websocket = new WebSocket(SIGNALING_SERVER);
 
websocket.onmessage = function (event) {
    var data = JSON.parse(event.data);
  
    if (data.isChannelPresent == false) {
        connection.open();
    } else {
        connection.join(roomid);
    }
};
 
websocket.onopen = function () {
    websocket.send(JSON.stringify({
        checkPresence: true,
        channel: roomid
    }));
};
