In this chapter, we explored how we can incorporate real-time functionality into an Ionic app using socket.io. In the process of doing so, we built a simple chat application, which can be expanded later in order to learn advanced real-time features.

In the next chapter, we'll take a look at how to set up WebSocket communication through the app in order to subscribe to dynamic notifications from a server. We will elaborate on how this helps us develop truly dynamic applications such as chat apps.
