Streaming video from HTML5 to node.js

Question

I have a node.js server which uses the "ws" npm package. From HTML5 I can get the users webcam stream but how do I send the webcam stream through a HTML5 websocket to my node.js server?

Currently I have this code on the server:

wss.on('connection', function(ws) {
  ws.on('message', function(data, flags) {
    console.log("Message received");
  });
});

And on the client this code:

var ws = new WebSocket('ws://localhost:8080');

ws.onopen = function() {
  ws.send(stream);
}

Where the stream is from navigator.getUserMedia with video: true.

Thanks in advance!

I would use the socket.io-stream npm package and then use something like this after configure it (works on server and client):

// send data 
ss(socket).on('file', function(stream) {
  fs.createReadStream('/path/to/file').pipe(stream);
});

// receive data 
ss(socket).emit('file', stream);
stream.pipe(fs.createWriteStream('file.txt'));
