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.

Working with styles and themes

Included with Material-UI are systems for extending the styles of UI components, and extending theme styles that are applied to all components. In this section, you'll learn about using both of these systems.

Making styles

Material-UI comes with a makeStyles() function that can be used to create styles based on JavaScript objects. The return value of this function is a Hook function, which, when used in a component, returns an object with the different style names as properties. There are two ways to use this style object with your Material-UI components:

  • The first is to pass the style name to the className property of the component:
const classes = makeStyles({ myStyle: { ... }});
<Button className={classes.myStyle} />

This will apply whatever CSS properties that you've defined in myStyle to the Button component. The challenge with this approach is that every Material-UI component has several styles applied to it and it's very easy...
