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.

Providing and consuming context

As your React application grows, it will use more components. Not only will it have more components, but the structure of your application will change so that the components are nested more deeply. The components that are nested at the deepest level still need to have data passed to them. Passing data from a parent component to a child component isn't a big deal. The challenge is when you have to start using components as indirection for passing data around your app.

For data that needs to make its way to any component in your app, you can create and use a context. There are two key concepts to remember when using contexts in React—providers and consumers. A context provider creates data and makes sure that it's available to any React components. A context consumer is a component that uses this data within the context.

You might be wondering whether or not context is just another way of saying global data in a React application. Essentially...
