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.

Giving touch feedback

The React Native examples you've worked with so far in this book have used plain text to act as buttons or links. In web applications, to make text look like something that can be clicked, you just wrap it with the appropriate link. There's no such thing as mobile links, so you can style your text to look like a button.

The problem with trying to style text as links on mobile devices is that they're too hard to press. Buttons provide a bigger target for fingers, and they're easier to apply touch feedback on.

Let's style some text as a button. This is a great first step as it makes the text look touchable. But you also want to give visual feedback to the user when they start interacting with the button. React Native provides two components to help with this: TouchableOpacity and TouchableHighlight. But before diving into the code, let's take a look at what these components look like visually when users interact with them, starting with...
