To get the most out of this book

All the projects in this book are created with React, React Native, or React 360 and require you to have prior knowledge of JavaScript. Although all the concepts of React and related technologies are described in this book, we advise you to refer to React docs if you want to find out more about a feature. In the following section, you can find some information about setting up your machine for this book and how to download the code for each chapter.

Set up your machine

For the applications that are created in this book, you'll need to have at least Node.js v10.16.3 installed on your machine so that you can run npm commands. If you haven't installed Node.js on your machine, please go to https://nodejs.org/en/download/, where you can find the download instructions for macOS, Windows, and Linux.

After installing Node.js, run the following commands in your command line to check the installed versions:

• For Node.js (should be v10.16.3 or higher):

node -v

• For npm (should be v6.9.0 or higher):

npm -v

Also, you should have installed the React Developer Tools plugin (for Chrome and Firefox) and added it to your browser. This plugin can be installed from the Chrome Web Store (https://chrome.google.com/webstore) or Firefox Addons (https://addons.mozilla.org).

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Since you're going to build a Movie List application in this chapter, name this directory movieList."

A block of code is set as follows:

{
    "name": "movieList",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1"
    },
    "keywords": [],
    "author": "",
    "license": "ISC"
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

import React from 'react';
import ReactDOM from 'react-dom';
+ import List from './containers/List';

const App = () => {
-   return <h1>movieList</h1>;
+   return <List />;
};

ReactDOM.render(<App />, document.getElementById('root'));

Any command-line input or output is written as follows:

npm init -y

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "When the user clicks the Close X button, the display styling rule of the component will be set to none."
