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.

Event Handling - The React Way

The focus of this chapter is event handling. React has a unique approach to handling events: declaring event handlers in JSX. I'll get things going by looking at how event handlers for particular elements are declared in JSX. Then, you'll learn about binding handler context and parameter values. Next, we'll implement inline and higher-order event handler functions.

Then, you'll learn how React actually maps event handlers to DOM elements under the hood. Finally, you'll learn about the synthetic events that React passes to event handler functions, and how they're pooled for performance purposes. Once you've completed this chapter, you'll be comfortable implementing event handlers in your React components. At that point, your applications come to life for your users because they are then able to interact with...
