Socket.io is not working after packing by using "yarn electron: builld".

Come from nkkayman's github. I don't know whether you can help me about my question below.

=================Original Issue===========================
Socket.io is not working after packing by using "yarn electron: builld".

However, the function is normal in development mode "yarn electron: serve". And normal for yarn server or yarn build.

I found the reason is socket client cannot be connected to server since the Invaild namespace.
The invaild namespace is "//app://.". I found the value by adding console for socket instance.
The normal namespace is "/" as default main namespace based on socket.io online document.

My question is that why the socket.io default namespace is changed to "//app://."? Any configuration file should be modified?

I am really not sure, but the only thing that seems relevant to me is https://matthijsburgh.github.io/vue-cli-plugin-electron-builder/guide/configuration.html#changing-the-file-loading-protocol.

Have a try with it.

No matter what. Thanks for your reply. I'll check the protocol.
