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.

Knowing what to expect

Property validation in React components is like field validation in HTML forms. The basic premise of validating form fields is letting the user know that they've provided a value that's not acceptable. Ideally, the validation error message is clear enough that the user can easily fix the situation. With React component property validation, you're doing the same thing making it easy to fix a situation where an unexpected value was provided. Property validation enhances the developer experience, rather than the user experience.

The key aspect of property validation is knowing what's passed into the component as a property value. For example, if you're expecting an array and a Boolean is passed instead, something will probably go wrong. If you validate the property values using the prop-types React validation package, then you know that something unexpected was passed. If the component is expecting an array so that it can call the...
