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.

Getting user confirmation

In this section, you'll learn how to show modal views in order to get confirmation from the user. First, you'll learn how to implement a successful scenario, where an action generates a successful outcome that you want the user to be aware of. Then, you'll learn how to implement an error scenario, where something went wrong and you don't want the user to move forward without acknowledging the issue.

Displaying a success confirmation

Let's start by implementing a modal view that's displayed as the result of the user successfully performing an action. Here's the Modal component, which is used to show the user a success confirmation:

import React from "react";
import PropTypes from "prop-types";
import { View, Text, Modal } from "react-native";
import styles from "./styles";

export default function ConfirmationModal(props) {
return (
<Modal {...props}>
<View style={styles.modalContainer...
