Socket.io server on .lp file

[buuuudzik]

Why two websockets? There's one localbus socket which is local UDP broadcast, another one is server-client TCP connection.

This was only theoretically question. I don't understand where in attached code there is the websocket assignment to some port. Because in a few examples which I read always there was some address + port 8080 (probably default for websocket);

Like below:

Code:

local ev = require'ev'

-- create a copas webserver and start listening
local server = require'websocket'.server.ev.listen
{
 -- listen on port 8080
 port = 8080,
 -- the protocols field holds
 --   key: protocol name
 --   value: callback on new connection
 protocols = {
   -- this callback is called, whenever a new client connects.
   -- ws is a new websocket instance
   echo = function(ws)
     ws:on_message(function(ws,message)
         ws:send(message)
       end)

     -- this is optional
     ws:on_close(function()
         ws:close()
       end)
   end
 }
}

-- use the lua-ev loop
ev.Loop.default:loop()
