I am new to node.js and currently working on a tcp server. I want all the 
messages to be sent to client in a compressed format.I am using zlib for 
this purpose.

The following sample is a code on server side:

    zlib.deflate(response.toString(), function(err, buffer) {
              if (!err) {
                session.xmlSocket.writeString(buffer);
                }
              }); 

This function basically compresses the data and writes it to the socket.The 
code on client side that decompress that data is:

    this.socket.on("data", function(chunk){
         zlib.unzip(chunk, function(err, buffer) {
         if (!err) {
                self.parser.write(buffer.toString());
            console.log(buffer.toString());
          }
        });

Now this code works fine when I run both client and server on the same 
pc.But is it correct to directly write the Buffer object returned by the 
zlib.deflate function and write it on the socket and then use it on the 
client side?
