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.

Declarative data fetching

As mentioned before, GraphQL is a query language that lets you define what the response of an API looks like by how you structure your query. Not only is it a query language, but it also provides a runtime to fulfill those queries based on your existing data. Not only can you use GraphQL to fetch data with queries, but you can also send mutate data by using mutations.

When you want to use GraphQL, the API that you're using for data fetching should support GraphQL. This means the server should have a schema that describes which operations (queries, mutations, or subscriptions) are allowed and which data fields can be requested. Every operation that is described in the schema for a GraphQL server can be executed by sending a document containing these operations. Other than with REST APIs, you have complete control over the shape of your data as you define what structure the response should have in your operation.

Let's get a taste of how GraphQL queries...
