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.

Step progress

In this final example, you'll build an app that displays the user's progress through a predefined number of steps. For example, it might make sense to split a form into several logical sections and organize them in such a way that, as the user completes one section, they move to the next step. A progress bar would be helpful feedback for the user.

You'll insert a progress bar into the navigation bar, just below the title, so that the user knows how far they've gone and how far is left to go. You'll also reuse the ProgressBar component that you implemented earlier in this chapter.

Let's take a look at the result first. There are four screens in this app that the user can navigate to. Here's what the first page (scene) looks like:

The progress bar under the title reflects the fact that the user is 25% through the navigation. Let's see what the third screen looks like:

The progress is updated to reflect where the user is in the route...
