Gestures Overview

Gesture hooks in React UI Animate provide a powerful, declarative way to handle user interactions. Whether you're building draggable cards, scroll-based animations, or custom cursor effects, these hooks simplify complex gesture handling.

What Are Gesture Hooks?​

Gesture hooks are React hooks that listen to user input events (mouse, touch, scroll, wheel) and provide clean, React-friendly APIs for handling interactions. They abstract away the complexity of pointer events, touch handling, and cross-browser differences.

Why Use Gesture Hooks?​

  • ✅ Declarative - Write interactions in a React-friendly way
  • ✅ Cross-platform - Works with mouse, touch, and pen input
  • ✅ Rich data - Get movement, velocity, offset, and more
  • ✅ Performant - Optimized event handling
  • ✅ Flexible - Works with single elements, multiple elements, or the window

Available Gesture Hooks​

useDrag​

Detects drag gestures with full control over movement, velocity, and direction. Perfect for draggable cards, sliders, and interactive elements.

Use cases:

  • Draggable cards and panels
  • Sliders and carousels
  • Sortable lists
  • Drag-to-dismiss interactions

useMove​

Tracks pointer movement without needing a press. Great for hover effects, custom cursors, and interactive elements that respond to mouse position.

Use cases:

  • Custom cursor effects
  • Hover interactions
  • Magnetic effects
  • Interactive cards that follow the cursor

useScroll​

Listens to native scroll events and provides detailed scroll dynamics. Perfect for scroll-triggered animations and parallax effects.

Use cases:

  • Scroll-triggered animations
  • Parallax effects
  • Progress indicators
  • Scroll-based reveals

useWheel​

Captures wheel/touchpad gestures with full delta, velocity, and offset tracking. Ideal for zoom interactions and custom scroll behavior.

Use cases:

  • Zoom controls
  • Custom scroll behavior
  • Horizontal scrolling with wheel
  • Gesture-driven navigation

Common Patterns​

Pattern 1: Drag with Spring Back​

import { useDrag, useValue, withSpring } from 'react-ui-animate';

function DraggableCard() {
  const ref = useRef(null);
  const [x, setX] = useValue(0);
  const [y, setY] = useValue(0);

  useDrag(ref, ({ down, movement }) => {
    if (down) {
      setX(movement.x);
      setY(movement.y);
    } else {
      // Spring back to center
      setX(withSpring(0));
      setY(withSpring(0));
    }
  });

  return (
    <animate.div
      ref={ref}
      style={{
        translateX: x,
        translateY: y,
        cursor: 'grab',
      }}
    >
      Drag me
    </animate.div>
  );
}

Pattern 2: Scroll Progress​

import { useScroll, useValue } from 'react-ui-animate';

function ScrollProgress() {
  const [progress, setProgress] = useValue(0);

  useScroll(window, ({ offset }) => {
    const maxScroll = document.documentElement.scrollHeight - window.innerHeight;
    setProgress(offset.y / maxScroll);
  });

  return (
    <div
      style={{
        position: 'fixed',
        top: 0,
        left: 0,
        width: `${progress * 100}%`,
        height: 4,
        background: '#60a5fa',
      }}
    />
  );
}

Pattern 3: Custom Cursor​

import { useMove, useValue } from 'react-ui-animate';

function CustomCursor() {
  const [pos, setPos] = useValue({ x: 0, y: 0 });

  useMove(window, ({ offset }) => {
    setPos({ x: offset.x, y: offset.y });
  });

  return (
    <animate.div
      style={{
        position: 'fixed',
        left: pos.x,
        top: pos.y,
        width: 20,
        height: 20,
        borderRadius: '50%',
        background: '#60a5fa',
        pointerEvents: 'none',
        translateX: -10,
        translateY: -10,
      }}
    />
  );
}

Best Practices​

✅ Do​

  • Combine gesture hooks with useValue for smooth animations
  • Use withSpring for natural release animations
  • Handle both down and release states in drag callbacks
  • Use transforms (translateX, translateY) instead of layout properties
  • Provide visual feedback (cursor changes, hover states)

❌ Don't​

  • Don't forget to handle cleanup when components unmount
  • Don't use layout properties (left, top) - use transforms
  • Don't forget to provide accessibility alternatives
  • Don't make gestures too sensitive (use thresholds when needed)

Performance Tips​

  1. Use transforms - translateX, translateY are GPU-accelerated
  2. Debounce when needed - For expensive operations in callbacks
  3. Use refs correctly - Pass stable refs to gesture hooks
  4. Batch updates - Update multiple values together when possible
