Overview of this book

If you are a developer looking to create mobile applications with maximized code reusability and minimized cost, React Native is what you need. With this practical guide, you’ll be able to build attractive UIs, tackle common problems in mobile development, and achieve improved performance in mobile environments. This book starts by covering the common techniques for React Native customization and helps you set up your development platforms. Over the course of the book, you’ll work through a wide variety of recipes that help you create, style, and animate your apps with built-in React Native and custom third-party components. You’ll also develop real-world browser-based authentication, build a fully functional audio player, and integrate Google Maps in your apps. This book will help you explore different strategies for working with data, including leveraging the popular Redux library and optimizing your app’s dataflow.

Setting up the Redux store

The Redux store is responsible for updating the information that is calculated on the state inside reducers. It is a single global object, which can be accessed via the store's getState method.

In this recipe, we'll tie together the actions and the reducer we created in previous recipes. We will use the existing actions to affect data that lives in the store. We will also learn how to log changes on the state by subscribing to the store changes. This recipe serves more as a proof of concept of how actions, reducers, and the store work together. We'll dive deeper into how Redux is more commonly used within apps later in this chapter.
