Localhost says upgrade required

Question

I am working on a web rtc project. I have create four files: index.html, server.js, client.js and package.json. My server is node.js. When I input node server.js, it produces nothing. Then, when i write on my web browser localhost:8080, it says upgrade required. Any solution? Please. Thanks in advance.

Answer 1

This means that you have a http server listening on 8080 without websocket capabilities. Your webrtc client needs websocket to be able to talk with the server. You need also socket.io. Example:

// Require HTTP module (to start server) and Socket.IO
var http = require('http'), io = require('socket.io');

// Start the server at port 8080
var server = http.createServer(function(req, res){ 

    // Send HTML headers and message
    res.writeHead(200,{ 'Content-Type': 'text/html' }); 
    res.end('<h1>Hello Socket Lover!</h1>');
});
server.listen(8080);

// Create a Socket.IO instance, passing it our server
var socket = io.listen(server);

// Add a connect listener
socket.on('connection', function(client){ 

    // Success!  Now listen to messages to be received
    client.on('message',function(event){ 
        console.log('Received message from client!',event);
    });
    client.on('disconnect',function(){
        clearInterval(interval);
        console.log('Server has disconnected');
    });

});
