useHover

A hook that detects when an element is being hovered over. Perfect for implementing hover effects, tooltips, or any interaction that depends on mouse hover state.

Parameters

• ref: RefObject<HTMLElement> - Reference to the element to monitor for hover

Returns

• boolean - True when the element is being hovered over, false otherwise

Usage

import { useHover } from '@rhinolabs/react-hooks';
import { useRef } from 'react';

function HoverCard() {
  const cardRef = useRef<HTMLDivElement>(null);
  const isHovered = useHover(cardRef);

  return (
    <div
      ref={cardRef}
      style={{
        padding: '20px',
        backgroundColor: isHovered ? '#f0f0f0' : 'white',
        transition: 'background-color 0.2s'
      }}
    >
      <h3>Hover Me!</h3>
      {isHovered && (
        <div className="tooltip">
          Additional information shown on hover
        </div>
      )}
    </div>
  );
}

Notes

• Uses mouseenter/mouseleave events with cross-browser support
• Implements type-safe ref handling with automatic cleanup
• Provides real-time state updates with boolean return value
• Optimizes performance with efficient event binding
• Prevents unnecessary re-renders through proper memoization
