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.

Building Flexbox layouts

In this section, you'll learn about several potential layouts that you can use in your React Native applications. I want to stay away from the idea that one layout is better than another. Instead, I'll show you how powerful the Flexbox layout model is for mobile screens so that you can design the layout that best suits your application.

Simple three-column layout

To start things off, let's implement a simple layout with three sections that flex in the direction of the column (top to bottom). Let's start by taking a look at the resulting screen:

The idea, in this example, is that you've styled and labeled the three screen sections so that they stand out. In other words, these components wouldn't necessarily have any styling in a real application since they're used to arrange other components on the screen.

Let's take a look at the components used to create this screen layout:

import React from "react";
import {...
