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.

The focus of this chapter has been React component property validation. When you implement property validation, you know what to expect; this promotes portability. The component doesn't care how the property values are passed to it, just as long as they're valid.

Then, you worked on several examples that used the basic React validators to check primitive JavaScript types. You also learned that if a property is required, it must be made explicit. Next, you learned how to validate more complex property values by combining the built-in validators that come with React.

Finally, you implemented your own custom validator functions to perform validation that goes beyond what's possible with the prop-types validators. In the next chapter, you'll learn how to handle navigation using React routes.
