Why the socket.IO example uses socket on the _app.js?

[theprobugmaker]

I installed the socket.IO example and I noticed that the socket instance is made in two places, on the hook and also on the _app.js the thing is that whenever I import the hook it will make a connection automatically and it will also make a connection because of _app.js (the server receives 2 connections), what is the reason to use in both places?

Anyone knows this?

The example was removed as it shows outdated practices and was generally not ideal

Thank you for the reply @timneutkens. I guess I'll have to go with another alternative then.
