React and React Native - Third Edition

By: Adam Boduch, Roy Derks

Overview of this book

React and React Native, Facebook’s innovative User Interface (UI) libraries, are designed to help you build robust cross-platform web and mobile applications. This updated third edition is improved and updated to cover the latest version of React. The book particularly focuses on the latest developments in the React ecosystem, such as modern Hook implementations, code splitting using lazy components and Suspense, user interface framework components using Material-UI, and Apollo. In terms of React Native, the book has been updated to version 0.62 and demonstrates how to apply native UI components for your existing mobile apps using NativeBase. You will begin by learning about the essential building blocks of React components. Next, you’ll progress to working with higher-level functionalities in application development, before putting this knowledge to use by developing user interface components for the web and for native platforms. In the concluding chapters, you’ll learn how to bring your application together with a robust data architecture. By the end of this book, you’ll be able to build React applications for the web and React Native applications for multiple mobile platforms.

Sharing data using context Hooks

React applications often have a few pieces of data that are global in nature. This means that several components, possibly every component in the app, share this data. For example, information about the currently logged-in user might be used in several places. In cases like this, it makes sense to provide a context where this data can be easily accessed by components that are rendered in this context.

In this section, you'll learn how to consume context data and how to consume it using Hooks.

Sharing fetched data

Most of our components will directly fetch the data that they and their children need. In other cases, our app has some API endpoint with data that is used by several components throughout the application. To share global data like this, you can use the React context API. As the name suggests, components that are rendered within a context are able to access the data provided by the context.

Let's build an example to help clarify what...
