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.

Vibration


The Vibration API allows us to tap into the vibration motor for our user's mobile devices and send a vibration to it.

This demo will require the use of actual hardware to test, but it is worth the setup if you have one to play with. On devices that don't support vibration, including the simulator, there will be no effect.

Note

There are a couple of caveats to using the Vibration API that you should be aware of.

From a user experience standpoint, the use of vibration in your apps should be as a feedback mechanism to let your users know that some sort of interaction has occurred.

Additionally, extended use of the vibration motor on a user's phone will lead to larger stress on their device's battery performance.

It's very easy to abuse this API and include vibrations on all aspects of your app, but I would heavily recommend that this feature is reserved to acknowledge key interactions that a user may have with your app.

It also has access to two methods:

  • The first method is Vibration.vibrate...
