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.

This chapter introduced you to the new React Hooks API. You started out by using the useState() Hook, which is fundamental for using state in functional React components. Then, you learned about useEffect(), which enables life cycle management in functional React components, such as fetching API data when the component is mounted and cleaning up any pending async operations when it is removed. Then, you learned how to use the useContext() Hook in order to access global application data. Lastly, you learned about the useReducer() Hook: an effective replacement for useState() when your component state grows too big or too complex for useState().

In the following chapter, you'll learn about event handling in React components.
