React Native By Example

By: Richard Kho

Overview of this book

React Native's ability to build performant mobile applications with JavaScript has resulted in its popularity amongst developers. Developers now have the luxury to create incredible mobile experiences that look and feel native to their platforms with the comfort of a well-known language and the popular React.js library. This book will show you how to build your own native mobile applications for the iOS and Android platforms while leveraging the finesse and simplicity of JavaScript and React. Throughout the book you will build three projects, each of increasing complexity. You will also link up with the third-party Facebook SDK, convert an app to support the Redux architecture, and learn the process involved in making your apps available for sale on the iOS App Store and Google Play. At the end of this book, you will have learned and implemented a wide breadth of core APIs and components found in the React Native framework that are necessary in creating great mobile experiences.

Initializing a new project

With the React Native SDK already installed, initializing a new React Native project is as simple as using the following command line:

react-native init Tasks

 

 

Let the React Native command line interface do its work for a few moments, then open the directory titled Tasks once it is completed.

From there, running your app in iOS Simulator is as easy as typing the following command:

react-native run-ios

This will start a process to build and compile your React Native app, launch the iOS Simulator, import your app to the Simulator, and start it. Whenever you make a change to the app, you will be able to reload and see those changes immediately.
