```bash
|
|
npx create-next-app --example with-socket.io with-socket.io-app

## The idea behind the example
|
|
|
|
This example show how to use [socket.io](https://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.
