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 icons

In the final section of this chapter, you'll learn how to render icons in React Native components. Using icons to indicate meaning makes web applications more usable. So, why should native mobile applications be any different?

You'll want to use the react-native-vector-icons package to pull in various vector font packages into your React Native project, as follows:

npm install --save @expo/vector-icons

Now, you can import the Icon components and render them. Let's implement an example that renders several FontAwesome icons based on a selected icon category:

import React, { useState, useEffect } from "react";
import { View, Picker, FlatList, Text } from "react-native";
import Icon from "react-native-vector-icons/FontAwesome";
import styles from "./styles";
import iconNames from "./icon-names.json";

export default function RenderingIcons() {
const [selected, setSelected] = useState("Web Application Icons&quot...
