17. Refs in React

Overview

This chapter will introduce you to how to use references in React. You will be able to apply the knowledge gained from the chapter to implement different ways of applying references. By the end of this chapter, you will be able to use Refs in your existing React application in an effective way.

Introduction

In the previous chapters, we learned about the various methods we can use to fetch data from external APIs and how to include that data inside your React application. This process required you to send XMLHttpRequest(XHR) requests over the network, take the result, and store it in your component.

A web page is often composed of more than just a React app; for example, an application can be embedded in a website ...
