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.

Collecting date/time input

In this final section of this chapter, you'll learn how to implement date/time pickers. React Native has independent date/time picker components for iOS and Android, which means that it is up to you to handle the cross-platform differences between the components.

So, let's start with a date picker component for iOS:

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

export default function DatePicker(props) {
return (
<View style={styles.datePickerContainer}>
<Text style={styles.datePickerLabel}>{props.label}</Text>
<DatePickerIOS mode="date" {...props} />

DatePicker.propTypes = {
label: PropTypes.string

There's not a lot to this component; it simply adds a label to the DatePickerIOS component. The Android version of the date picker needs...
