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.

Code Splitting Using Lazy Components and Suspense

Code splitting has been happening in React applications for some time now, long before there was any official support in the React API. With the latest version of React, there are new APIs that we can use that directly support code-splitting scenarios. Code splitting is necessary when you have larger applications with a lot of JavaScript code that must be delivered to the browser.

Big monolithic JavaScript bundles that house the entire application can create usability issues on initial page loads due to longer load times. With code splitting, we have more fine-grained control over how code makes its way from the server to the browser. This means more opportunities for us to properly handle load-time User Experience (UX). You'll learn how to do this in your React applications by using the lazy() API and the Suspense components...
