React Projects - Second Edition

By: Roy Derks

Overview of this book

Developed by Facebook, React is a popular library for building impressive user interfaces. React extends its capabilities to mobile platforms using the React Native framework and integrates with popular web and mobile tools to build scalable applications. React Projects is your guide to learning React development by using modern development patterns and integrating React with powerful web tools, such as GraphQL, Expo, and React 360. You'll start building a real-world project right from the first chapter and get hands-on with developing scalable applications as you advance to building more complex projects. Throughout the book, you'll use the latest versions of React and React Native to explore features such as routing, Context, and Hooks on multiple platforms, which will help you build full-stack web and mobile applications efficiently. Finally, you'll get to grips with unit testing with Jest and end-to-end testing with Cypress to build test-driven apps. By the end of this React book, you'll have developed the skills necessary to start building scalable React apps across web and mobile platforms.

Summary

In this chapter, you've created a shopping list application that uses the Context API and Hooks to pass and retrieve data. Context is used to store data and Hooks are used to retrieve and mutate data. With the Context API, you can create more advanced scenarios for state management using the useReducer Hook. Context is also used to create a situation where all of the data is stored application-wide and can be accessed from any component by creating a shared Context. Finally, we've used React Suspense to apply code splitting to our bundle for improved performance.

The Context API will be used in the next chapter as well, which will show you how to build a hotel review application with automated testing using libraries such as Jest and Enzyme. It will introduce you to the multiple ways in which you can test your UI components created with React, and also show you how to test state management in your application using the Context API.
