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.

Refactoring component structures

You have a monolithic feature component—now what? Let's make it better.

In this section, you'll learn how to take the feature component that you just implemented in the preceding section and split it into more maintainable components. You'll start with the JSX, as this is probably the best refactor starting point. Then, you'll implement new components for the feature.

Next, you'll make these new components functional, instead of class-based. Finally, you'll learn how to use render props to reduce the number of direct component dependencies in your application and how to remove classes entirely by using Hooks to manage state within functional components.

Starting with the JSX

The JSX of any monolithic component is the best starting point for figuring out how to refactor it into smaller components. Let's visualize the structure of the component that we're currently refactoring:

The top part of the JSX is the...
