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.

Rendering imperative components

Everything you've rendered so far in this book has been straightforward declarative HTML. Life is never so simple: sometimes, your React components need to implement some imperative code under the covers.

This is the key hiding the imperative operations so that the code that renders your component doesn't have to touch it. In this section, you'll implement a simple jQuery UI button React component so that you can see how the relevant life cycle methods help you to encapsulate the imperative code.

Rendering jQuery UI widgets

The jQuery UI widget library implements several widgets on top of standard HTML. It uses a progressive enhancement technique whereby the basic HTML is enhanced in browsers that support newer features. To make these widgets work, you first need to render HTML into the DOM somehow; then, you need to make imperative function calls to create and interact with the widgets.

In this example, you'll create a React...
