D alternative for node.js's socket.IO?

[Fleel via Digitalmars-d]

Does anyone know of a good D alternative for the socket.IO server 
(https://socket.io)? I would like to transition my server from 
node.js to D, but I can't find any D equivalents to socket.IO. 
(I've seen http://socket.io.dub.pm, but it is dead). Are there 
any good D libraries that can do the same thing as socket.IO? 
Thanks!
