can't return nothing from an event handler

[dude8604]

With the javascript socket.io, if fn is the server's callback question to the client, calling fn() will send a blank response to the client. Is there a way to do that with this library? I've tried all I can think of, but it always sends at least true, false, or null, but never just blank like the original socket.io. Is this a limitation of this library or am I doing something wrong?

It's a bug, you are right. If you don't return anything, the library will call the callback function with (null). One way to trick it into doing the right thing is, I think, to return an empty tuple:

return tuple()

Have you tried that?

In any case, I will fix this.

Thanks, that worked.
