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.

Frontend reconciliation

The only thing that was missing from the last example was the client JavaScript code. The user wants to use the application and the server needs to deliver the client's code bundle. How would this work? Routing has to work in the browser and on the server, without modifying the routes. In other words, the server handles routing in the initial request, then the browser takes over as the user starts clicking on things and moving around in the application.

Let's create the index.js module for this example:

import React from "react";
import { hydrate } from "react-dom";
import App from "./App";

hydrate(<App />, document.getElementById("root"));

This looks like most other index.js files that you've seen so far in this book. You render the <App> component in the root element in the HTML document. In this case, you're using the hydrate() function instead of the render() function. The two functions have...
