UI KitHooksuseDebounce

Overview

The useDebounce hook is an essential tool in modern React development, particularly useful in optimizing performance for actions that involve rapidly changing data. By delaying the invocation of a value until a specified wait time has elapsed, it prevents unnecessary updates and re-renders, thus improving the efficiency of your application.

By integrating useDebounce in your application, you can optimize performance for scenarios involving rapidly changing data, ensuring a smooth and efficient user experience.

Key Features

  • Value Debouncing: Delays the update of a value until after a specified wait time.
  • Performance Optimization: Reduces unnecessary function calls and re-renders.
  • Generic Implementation: Can be used with various data types and scenarios.

How It Works

The hook takes in a value and a delay time in milliseconds. It utilizes useState and useEffect from React to manage and delay the value update. The debounced value is updated only after the specified delay time has passed since the last change to the input value.

Syntax

const debouncedValue = useDebounce(value, delay);
  • value: The value to be debounced.
  • delay: The delay time in milliseconds before the value is updated.

Usage Example

Here’s an example of how useDebounce can be used in a search input scenario:

import { useState } from 'react';
import { useDebounce } from '@akinon/ui-hooks';
 
const SearchComponent = () => {
  const [searchTerm, setSearchTerm] = useState('');
  const debouncedSearchTerm = useDebounce(searchTerm, 500);
 
  const handleSearch = event => {
    setSearchTerm(event.target.value);
  };
 
  // Use debouncedSearchTerm for fetching data or other side effects
 
  return (
    <input
      type="text"
      value={searchTerm}
      onChange={handleSearch}
      placeholder="Search..."
    />
  );
};
 
export default SearchComponent;
