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.

These are displayed in a less obtrusive way than modals and don't require any user action to dismiss them.

In this section, you'll create a Notification component that uses the Toast API for Android and creates a custom modal for iOS. It's called the Toast API because the information that's displayed looks like a piece of toast popping up. Here's what the Android component looks like:

import React from "react";
import PropTypes from "prop-types";
import { ToastAndroid } from "react-native";

export default function Notification({ message, duration }) {
