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.

Viewing your app on your phone

In order to view your React Native project on your device during development, we need to start the Expo development server:

  1. In the command-line terminal, make sure that you're in the project directory:
cd path/to/my-project
  1. Once you're in my-project, you can run the following command to start the development server:
npm start
  1. This will show you some information about the developer server in the terminal:
Starting project at C:\Users\adamb\React-and-React-Native---Third-Edition\Chapter13\my-project
Expo DevTools is running at http://localhost:19002
Opening DevTools in the browser... (press shift-d to disable)
Starting Metro Bundler on port 19001.
Tunnel ready.
  1. It will also open a browser tab with a UI for managing where the application is run, viewing logs, and other miscellaneous activities. Here is what the Expo app looks like:

On the right side of the screen is where you'll find logs that come from the bundler, the process that bundles...
