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.

In this chapter, you learned a lot about the life cycle of React components. We started things off with a discussion on why React components need a life cycle in the first place. It turns out that React can't do everything automatically for us, so we need to write some code that's run at the appropriate time during the components' life cycles.

Next, you implemented several components that were able to fetch their initial data and initialize their state from JSX properties. Then, you learned how to implement more efficient React components by providing a shouldComponentRender() method.

After that, you learned how to hide the imperative code that some components need to implement and how to clean up after asynchronous behavior. Finally, you learned how to use the new error boundary functionality from React 16.

In the next chapter, you'll learn techniques that help to ensure that your components are being passed the right properties.
