NodeJS send string

Question

As I see Node JS can't send string to client.
When I use socket.write("string") client doesn't receive anything. socket.write(new Buffer("string")) — same situation.

var b = new Buffer(15);
b.write("string");
socket.write(b);

It looks like something works, but client receives string along with a lot of blank space.

var b = new Buffer(6); //6 - lenght of string in bytes
b.write("string");
socket.write(b);

Again nothing!

var b = new Buffer(7);
b.write("string");
socket.write(b);

Now there's less blank characters.
My head really hurts. Is it really complicated to send simple string?
Waiting for my savior :)

socket.write("string") actually works fine. Check the docs.

You forgot to end the transmission, after each write do a socket.end();

Also, if you're only sending one string you can always do a socket.end(stringToSend);

Please also refer to NodeJS documentation of the modul 'net'.

Huh? Why end? I'm developing browser MMO. So every sent message should disconnect user from server?

when you do a socket.end(), it ends the current message, doesn't disconnect the socket, it just tells the client-side that the message being sent in that section is the last one in that batch.
