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.

Validating Component Properties

In this chapter, you'll learn about property validation in React components. This might seem simple at first glance, but it's an important topic because it leads to bug-free components. I'll start things off with a discussion about predictable outcomes and how this leads to components that are portable throughout the application.

Next, you'll walk through examples of some of the type-checking property validators that come with React. Then, you'll walk through some more complex property-validation scenarios. Finally, I'll wrap this chapter up with an example of how to implement your own custom validators.

The following topics will be covered in this chapter:

  • Knowing what to expect
  • Promoting portable components
  • Simple property validators
  • Type and value validators
  • Writing custom property validators
