Before you begin this guide, you’ll need the following: 1. useTimeout is a React custom hook that sets a leak-safe timeout and returns a function to cancel it before the timeout expires. But I found it to be lacking key advice concerning integration tests, and how to use Storybook to boost observability and debuggability.. Debouncing in software development in simple is a technique used to save computing resources by doing the expensive computations only on the latest input when the input changes very frequently. Typescript components make it an absolute pleasure for developers to integrate your components into their apps and explore your APIs. React hooks are useful as they allow you to encapsulate and reuse stateful logic in your components. So, keeping this requirement in mind let's build a custom hook called useDebounce. if (timeout.current) {... this.setState provides a callback which is called when state has been updated and can be leveraged to access updated state values. Use the useRef() hook to create a ref for the callback function. Jump directly to the code here. JavaScript provides a handy method for executing some code after a specified amount of time: window.setTimeout.

The guide will start with a very simple label component that will have a prop called text and display it inside a span, then extend this component to highlight the text when the prop is changed by the parent component.The implementation of the text highlighting will set the component state to a background color, set a timeout of one second, and set the state back to the original background color.
