React and React Native - Third Edition

By: Adam Boduch, Roy Derks

Overview of this book

React and React Native, Facebook’s innovative User Interface (UI) libraries, are designed to help you build robust cross-platform web and mobile applications. This updated third edition is improved and updated to cover the latest version of React. The book particularly focuses on the latest developments in the React ecosystem, such as modern Hook implementations, code splitting using lazy components and Suspense, user interface framework components using Material-UI, and Apollo. In terms of React Native, the book has been updated to version 0.62 and demonstrates how to apply native UI components for your existing mobile apps using NativeBase. You will begin by learning about the essential building blocks of React components. Next, you’ll progress to working with higher-level functionalities in application development, before putting this knowledge to use by developing user interface components for the web and for native platforms. In the concluding chapters, you’ll learn how to bring your application together with a robust data architecture. By the end of this book, you’ll be able to build React applications for the web and React Native applications for multiple mobile platforms.

In this chapter, we learned about the need to show mobile users important information. This sometimes involves explicit feedback from the user, even if that just means acknowledging the message. In other cases, passive notifications work better, since they're less obtrusive than confirmation modals.

There are two tools that we can use to display messages to users: modals and alerts. Modals are more flexible because they're just like regular views. Alerts are good for displaying plain text and they take care of styling concerns for us. On Android, we have the ToastAndroid interface as well. We saw that it's also possible to do this on iOS, but it just requires more work.

In the next chapter, we'll dig deeper into the gesture response system inside React Native, which makes for a better mobile experience than browsers are able to provide.
