next.js/examples/with-socket.io/server.js
Bünyamin Benny Genel 6ed2da4575 with-socket.io Example updated with _app.js (#4644)
with-socket.io example was using a single index file and was managing connection in there. This would lead handling connection (disconnecting and reconnecting) in each added page.

I updated example with addition of `_app.js` and handled connection in there. This helped only subscribing to event in page and maintaining connection throughout example.
