Network Library with Websockets

[Thorium]

Would be cool to have a network library which works with Websockets.

I have to write my own because I can't wait.. It sucks..

to do it from the editor you have to basically wrap everything in functions with all the class and callback stuff escaped, then set states with the callbacks which you monitor with timers. A lot of time wasted..

Any news on WEBSOCKETS ?

does anyone have it implemented already ?
(like http://www.purebasic.fr/english/viewtop ... =Websocket)

Perhaps this is a starting point for you:

Code: Select all

Procedure doSend(message.s)
  Debug "Sending: " + message
  ! websocket.send(v_message);
  Debug "-------"
EndProcedure

Procedure onOpen(evt) 
  Debug "onOpen()"
  ; Debug evt
  Debug "-------"
  doSend("WebSocket rocks")
EndProcedure

Procedure onClose(evt)
  Debug "onClose"
  ; Debug evt
  Debug "-------"
EndProcedure

Procedure onMessage(evt)
  Debug "onMessage()"
  Protected MessageFromWs.s
  ! v_messagefromws = v_evt.data;
  Debug "MessageFromWs: " + MessageFromWs
  Debug "-------"
  ! websocket.close();
EndProcedure

Procedure onError(evt)
  Debug "onError()"
  ; Debug evt
  Debug "-------"
EndProcedure

Procedure Dummy()
  onOpen(0)
  onClose(0)
  onMessage(0)
  onError(0)
EndProcedure

Procedure initWebSocket(wsUri.s)
  ! websocket = new WebSocket(v_wsuri);
  ! websocket.onopen = function(evt) { f_onopen(evt) };
  ! websocket.onclose = function(evt) { f_onclose(evt) };
  ! websocket.onmessage = function(evt) { f_onmessage(evt) };
  ! websocket.onerror = function(evt) { f_onerror(evt) };
EndProcedure


initWebSocket("ws://echo.websocket.org/")

Thanks Peter, very useful code.

I'm currently working on modules on github. I'll be creating a module for WebSockets too.

It's not yet ready but it can be found here once it is: https://github.com/sworteu/XJS

@sworteu Great modules, thanks for sharing. Local and session storage should be 'built-in' imho, so @fred should take a look at your code...

They are not yet completed. Code may be build-in but that's up to fred.
I'd make spiderbasic same as purebasic if i where fred.

Just to add: use wss:// for HTTPS/TLS enabled domains and only when the certificate is signed by a CA. Modern browsers need modified to support self-signed or revoked certificates anywhere including websocket implementations.

I'd imagine Fred&Team will add this at some point considering most browser stuff uses push type notifications(server sends to clients instead of clients polling/timed-requesting and stressing the server) these days and most web hosts don't support long-polling HTTP connections even if over ajax.

Now that SB supports memory operations i am reevaluating if it fits a project i plan to start soon.
Only thing missing for me is websocket support.
Anyone has allready done a module for binary websockets?
