useDebounce Hook

React hook for debouncing values with TypeScript support.

Delays updating a value until user stops typing, perfect for search inputs to reduce API calls.

useDebounce.tstypescript

import { useState, useEffect } from 'react';

export function useDebounce<T>(value: T, delay: number = 500): T {
  const [debouncedValue, setDebouncedValue] = useState<T>(value);

  useEffect(() => {
    const handler = setTimeout(() => {
      setDebouncedValue(value);
    }, delay);

    return () => {
      clearTimeout(handler);
    };
  }, [value, delay]);

  return debouncedValue;
}

// Usage Example
function SearchComponent() {
  const [searchTerm, setSearchTerm] = useState('');
  const debouncedSearch = useDebounce(searchTerm, 300);

  useEffect(() => {
    if (debouncedSearch) {
      // API call here
      console.log('Searching:', debouncedSearch);
    }
  }, [debouncedSearch]);

  return <input onChange={(e) => setSearchTerm(e.target.value)} />;
}

Usage

const debouncedValue = useDebounce(searchTerm, 300);
