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 was all about code splitting and bundling, which are important concepts for larger React applications. We started by looking at how code is split into bundles in your React applications, by using the import() function. Then, we looked at the lazy() React API and how it helps to simplify loading bundles when components are rendered for the first time. Next, we looked more deeply at the Suspense component, which is used to manage content while component bundles are being fetched. The fallback property is how we specify the content to be shown while bundles are being loaded. You typically don't need more than one Suspense component in your app, as long as you follow a consistent pattern for bundling pages of your app.

In the next chapter, you'll learn how to use the Next.js framework to handle rendering React components on the server. The Next.js framework allows you to create pages that act as React components and can be rendered on the server and in the browser...
