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.

Render props

Imagine implementing a feature that is composed of several smaller components – like what you've been working on in this chapter. The MyFeature component depends on ArticleList and AddArticle. Now imagine using MyFeature in different parts of your application where it makes sense to use a different implementation of ArticleList or AddArticle. The fundamental challenge is substituting one component for another.

Render props are a nice way to address this challenge. The idea is that you pass a property to your component whose value is a function that returns a component to render. This way, instead of having the feature component directly depend on its child components, you can configure them as you like; they pass them in as render prop values.

Render props aren't a React 16 feature. They're a technique whose popularity increase coincided with the release of React 16. It's an officially recognized way to deal with dependency and substitution problems...
