Question

I\'m a beginner on node.js and socket.io. Socket.io began to support binary stream from 1.0, is there a complete example especially for image push to client and show in canv

Answer 1

thanks, @sovente, in this 1.0 introduction http://socket.io/blog/introducing-socket-io-1-0/ , this is code snippet on binary support.

var fs = require('fs');
var io = require('socket.io')(3000);
io.on('connection', function(socket){
  fs.readFile('image.png', function(err, buf){
    // it's possible to embed binary data
    // within arbitrarily-complex objects
    socket.emit('image', { image: true, buffer: buf });
  });
});

i want to know how to handle the buffer on client side, codes are like:

 socket.on("image", function(image, buffer) {
     if(image)
     {
         console.log(" image: ");
         **// code to handle buffer like drawing with canvas**
     }

 });
