Manual disconnect and reconnect to same URL

[moehlone]

I want to disconnect manually from a socket and to a later time make a new connection to the same URL. At the moment it is not possible with sails.js - reconnection always fails.

Is there any possibility to solve this with sails.io.js?
See: socketio/socket.io-client#251

socket.io implemented in 1.0 a param called 'forceNew' for io.connect()

Best regards,
Phil

@moehlone I was just about to ask this same question. In my case I want to unsubscribe from all models on log out, so I was hoping to just disconnect then reconnect the sails.io client. I got it to disconnect using io.socket.disconnect, but I can't figure out how to reconnect.

I'm having the same issue as well.

@eulercodex I used location.reload to accomplish this. If you are doing a SPA and don't want the flicker of a refresh, pass false for forceReload. The reload will happen from cache, but Sails.io will still reinitialize. Personally, I was wanting to reset all of the subscriptions to the pubsub system on logout; this seemed to do it.

@mattblang I don't particularly use sails. The issue was with socket.io but after looking at the doc online 1.2 release note, I was able to solve my problem this way

// on initialization
socket = io.connect({forceNew: true});
// for disconnection
socket.io.disconnect();
// for reconnection
socket = io.connect({forceNew: true});

io.connect({forceNew: true});

works just fine

if you are using sails you need to edit sails.io.js SailsSocket function:

   function SailsSocket (opts){
      var self = this;
      opts = opts||{};

      // Absorb opts
      self.useCORSRouteToGetCookie = opts.useCORSRouteToGetCookie;
      self.url = opts.url;
      self.multiplex = opts.multiplex;
      self.transports = opts.transports;

      // Absorb forceNew opts to force a new websocket connection every time
      self.forceNew = opts.forceNew;

      .
      .
      .

@ghost @eulercodex I had the similar problem here, and seems this forceNew option does the job well...

The following way for power saving or reducing network traffic works fine in my case for platform browser or android. Also, it is not necessary to redefine the event handler for 'connect' setup in app config.

# power saving or reduce network traffic
document.addEventListener 'pause', ->
    io.socket._raw.disconnect()

document.addEventListener 'resume', ->
    io.socket._raw.connect()
