Introduction

The useDebounce hook is a custom hook for debouncing a value in React. It allows you to delay the update of a value until a specified delay has passed without any new changes.

Why useDebounce

Debouncing values can be useful in scenarios where you want to delay processing or actions triggered by user input. It helps to reduce unnecessary updates and improve performance, especially when dealing with fast-changing input values like search queries or autocomplete suggestions.

Installation

To use useDebounce in your project, you can create a file (e.g., useDebounce.ts) and place the hook implementation inside it. Then, you can import and use it in your React components.

Usage

To use the useDebounce hook in your React components, import it and call it in your functional component like this:

import React, { useState } from 'react'
import { useDebounce } from '@pillar-ui/hooks'

function MyComponent() {
  const [inputValue, setInputValue] = useState('')
  const debouncedValue = useDebounce(inputValue, 500)

  const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setInputValue(event.target.value)
  }

  return (
    <div>
      <input type="text" value={inputValue} onChange={handleChange} />
      <p>Debounced value: {debouncedValue}</p>
    </div>
  )
}

In this example, the useDebounce hook takes an initial value and a delay in milliseconds. It returns a debounced value that is updated after the specified delay has passed without any new changes to the input value.

Implementation details

The useDebounce hook uses the useState and useEffect hooks from the React library to manage the debounced value and the update logic respectively. It sets a timeout to update the debounced value after the specified delay, canceling the previous timeout whenever the value changes within the delay.

TypeScript Support

This hook is written in TypeScript and provides type definitions for its usage, allowing you to specify the type of the debounced value.

Troubleshooting

If you encounter any issues using the useDebounce hook, please refer to the documentation or seek help on the relevant forums or communities.

Conclusion

The useDebounce custom hook is a handy tool for debouncing values in React applications. By using this hook, you can control the frequency of updates and improve performance in scenarios where delayed updates are desired.##
