useDebounce Hook

The useDebounce hook is used to delay the execution of a function until a specified amount of time has passed since it was last invoked. This is useful for handling rapid user input scenarios, such as search input fields or window resizing.

Installation

npm install @custom-react-hooks/use-debounce

or

yarn add @custom-react-hooks/use-debounce

Usage

Here's an example of using useDebounce in a search input component:

import React, { useState } from 'react';
import useDebounce from 'custom-react-hooks/useDebounce';

const DebounceTestComponent: React.FC = () => {
  const [inputValue, setInputValue] = useState('');

  const debouncedLog = useDebounce((val: string) => {
    console.log(`Debounced value: ${val}`);
  }, 1000)[0];

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

  return (
    <div>
      <input
        type="text"
        value={inputValue}
        onChange={handleChange}
      />
    </div>
  );
};

export default DebounceTestComponent;

In this component, the search function is debounced, which means it will only execute 500 milliseconds after the user stops typing.

API Reference

Parameters

• callback (Function): The function to debounce.
• delay (number): The number of milliseconds to delay.
• options (object, optional): Configuration options for the debounce behavior. Options include:
  • maxWait (number): The maximum time the function can be delayed before it's executed, regardless of subsequent calls.
  • leading (boolean): If true, the function is executed on the leading edge of the timeout.
  • trailing (boolean): If true, the function is executed on the trailing edge of the timeout.

Returns

• [debouncedFunction, cancelDebounce]:
  • debouncedFunction (Function): The debounced version of the provided function.
  • cancelDebounce (Function): A function that can be called to cancel the debounced action.

Notes

• The useDebounce hook is useful for optimizing performance in scenarios where you want to limit the frequency of function execution.
• Make sure to adjust the delay based on your specific use case.
