Overview of this book

Are you interested in how React takes command of the view layer for web and mobile apps and changes the data of large web applications without needing to reload the page? This workshop will help you learn how and show you how to develop and enhance web apps using the features of the React framework with interesting examples and exercises. The workshop starts by demonstrating how to create your first React project. You’ll tap into React’s popular feature JSX to develop templates and use DOM events to make your project interactive. Next, you’ll focus on the lifecycle of the React component and understand how components are created, mounted, unmounted, and destroyed. Later, you’ll create and customize components to understand the data flow in React and how props and state communicate between components. You’ll also use Formik to create forms in React to explore the concept of controlled and uncontrolled components and even play with React Router to navigate between React components. The chapters that follow will help you build an interesting image-search app to fetch data from the outside world and populate the data to the React app. Finally, you’ll understand what ref API is and how it is used to manipulate DOM in an imperative way. By the end of this React book, you’ll have the skills you need to set up and create web apps using React.

Preface

Summary

In this chapter, we have covered a really interesting part of React. The reality is that Refs are not something you are regularly going to encounter unless you are responsible for creating component libraries or working with more design-focused elements.

It is an interesting part of React because, as you might have noticed, Refs do not really fit into React's declarative style. Every time we use Refs, we use them to tell the browser how to do things instead of what we want to see. While not necessarily a problem, it can get complicated and we need to be clear about our intent when using Refs.

The best we can do is to hide most of what we are doing with Refs and ensure that anyone using our code only interacts with our components via props. If we need to access details more closely related to how the browser renders the component (such as focus, scrolling, or dimensions), that will require Refs because React can't handle it without them, but ultimately, the consumer...
