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. You’ll also learn how to write native device functionality for new and existing React Native projects and how app deployment works.

Defining actions

An action is a payload of information that sends data to the store. Using these actions is the only way components can request or send data to the Redux store, which serves as the global state object for the entire app. An action is just a plain JavaScript object. We'll be defining functions that return these actions. A function that returns an action is called an action creator.

In this recipe, we'll create the actions to load the initial images for the gallery. During this recipe, we'll be adding hardcoded data, but later on, we'll request this data from an API to create a more realistic scenario.

Getting ready

Let's continue working on the code from the previous recipe. Make sure...
