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. |

The idea behind the example
This example show how to use socket.io inside a Next.js application. It uses getInitialProps to fetch the old messages from a HTTP endpoint as if it was a Rest API. The example combine the WebSocket server with the Next server, in a production application you should split them as different services.
