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.

Progress and usability

Imagine that you have a microwave oven that has no window and makes no sound. The only way to interact with it is by pressing a button labeled Cook.

One way to improve the microwave situation is to add sound. This way, the user gets feedback after pressing the Cook button. You've overcome one hurdle, but the user is still left guessing, "where's my food?". Before you go out of business, you had better add some sort of progress measurement display, such as a timer.

It's not that UI programmers don't understand the basic principles of this usability concern; it's just that we have stuff to do and this sort of thing simply slips through the cracks in terms of priority. In React Native, there are components for giving the user...
