Question

Error: The connection to  was interrupted while the page was loading.
Source File: localhost/socket.io/node_modules/socket.io-client/dist/socket.io.         


        

Answer 1

It happens because, you are not closing your open websocket.

This code would remove this error:

$(window).on('beforeunload', function(){
    socket.close();
});
