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.

Using vector icons

In Chapter 3, Our Second Project - The Budgeting App, we mentioned that upon tapping that button, the user should be shown a modal that allows them to input details for their expenses: the name, amount, date the purchase was made on, and an icon to categorize the item.

We can import react-native-vector-icons with the following statement:

import Icon from '                        ...
