One-to-one communication is the main use for mobile phones although, text messaging has been quickly replaced by direct messaging apps. In this chapter, we will build a messaging app in React Native with the support of Firebase, a mobile backend as a service that will free us from having to build a whole backend for our app. Instead, we will focus on handling the state of our app fully from the frontend.
