The animate Component

The <animate> component is the foundation of React UI Animate. It works exactly like regular HTML elements (div, span, button, etc.) but understands animated values and provides powerful declarative animation props.

Basic Usage​

The animate component provides wrappers for all HTML elements:

import { animate } from 'react-ui-animate';

function MyComponent() {
  return (
    <animate.div
      style={{
        width: 100,
        height: 100,
        background: '#60a5fa',
        borderRadius: 4,
      }}
    >
      Hello World
    </animate.div>
  );
}

Available Elements​

You can use animate with any HTML element:

<animate.div>Div element</animate.div>
<animate.span>Span element</animate.span>
<animate.button>Button element</animate.button>
<animate.section>Section element</animate.section>
<animate.img src="..." alt="..." />
// ... and any other HTML element

Using Animated Values​

The real power comes when you combine animate with useValue:

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

function AnimatedBox() {
  const [width, setWidth] = useValue(100);

  return (
    <>
      <button onClick={() => setWidth(withSpring(200))}>
        Expand
      </button>
      <animate.div
        style={{
          width,  // Use animated value directly
          height: 100,
          background: '#60a5fa',
        }}
      />
    </>
  );
}

The width value automatically animates when you call setWidth with an animation modifier.

Declarative Animation Props​

React UI Animate provides declarative props for common interactions. These props accept animation descriptors:

animate - Initial/Mount Animation​

Animate when the component mounts or when the prop changes:

<animate.div
  animate={{
    opacity: withSpring(1),
    scale: withSpring(1),
  }}
  style={{
    opacity: 0,
    scale: 0.8,
  }}
>
  Content
</animate.div>

exit - Unmount Animation​

Animate when the component unmounts (requires Presence wrapper):

import { Presence } from 'react-ui-animate';

<Presence>
  {isVisible && (
    <animate.div
      exit={{
        opacity: withTiming(0),
        scale: withSpring(0.8),
      }}
    >
      Content
    </animate.div>
  )}
</Presence>

hover - Hover Animation​

Animate when the user hovers:

<animate.button
  hover={{
    scale: withSpring(1.1),
    backgroundColor: withSpring('#3399ff'),
  }}
>
  Hover me
</animate.button>

press - Press Animation​

Animate when the user presses (mousedown/touchstart):

<animate.button
  press={{
    scale: withSpring(0.95),
  }}
>
  Press me
</animate.button>

focus - Focus Animation​

Animate when the element receives focus:

<animate.input
  focus={{
    scale: withSpring(1.02),
    borderColor: withSpring('#3399ff'),
  }}
/>

view - Viewport Animation​

Animate when the element enters the viewport:

<animate.div
  view={{
    opacity: withTiming(1),
    translateY: withSpring(0),
  }}
  style={{
    opacity: 0,
    translateY: 50,
  }}
  viewOptions={{
    threshold: 0.3,
    once: true,
  }}
>
  Scroll to see me
</animate.div>

Combining Props​

You can use multiple animation props together:

<animate.button
  animate={{
    opacity: withSpring(1),
  }}
  hover={{
    scale: withSpring(1.1),
  }}
  press={{
    scale: withSpring(0.95),
  }}
>
  Interactive Button
</animate.button>

Preset Animations​

React UI Animate includes preset animations for common use cases:

import { hoverScale, pressScale } from 'react-ui-animate';

<animate.button
  hover={hoverScale}
  press={pressScale}
>
  Button with presets
</animate.button>

Style Props​

The animate component accepts all standard React style props, plus animated transform properties:

<animate.div
  style={{
    // Standard CSS properties
    width: 100,
    height: 100,
    backgroundColor: '#60a5fa',
    
    // Animated transform properties (shorthand)
    translateX: 100,
    translateY: 50,
    scale: 1.2,
    rotate: 45,
    opacity: 0.8,
  }}
/>

Animated transform properties:

  • translateX - Horizontal translation
  • translateY - Vertical translation
  • scale - Scale transformation
  • rotate - Rotation in degrees
  • opacity - Opacity (0-1)

These properties work seamlessly with animated values from useValue.

Real-World Examples​

Example 1: Interactive Card​

function InteractiveCard() {
  return (
    <animate.div
      style={{
        width: 200,
        height: 200,
        background: 'white',
        borderRadius: 8,
        boxShadow: '0 2px 8px rgba(0,0,0,0.1)',
      }}
      hover={{
        scale: withSpring(1.05),
        boxShadow: withSpring('0 4px 16px rgba(0,0,0,0.2)'),
      }}
      press={{
        scale: withSpring(0.98),
      }}
    >
      <h3>Card Title</h3>
      <p>Card content</p>
    </animate.div>
  );
}

Example 2: Animated Input​

function AnimatedInput() {
  return (
    <animate.input
      type="text"
      placeholder="Enter text"
      style={{
        padding: '10px',
        border: '2px solid #e1e1e1',
        borderRadius: 4,
      }}
      focus={{
        borderColor: withSpring('#3399ff'),
        scale: withSpring(1.02),
      }}
    />
  );
}

Example 3: Scroll-Triggered Reveal​

function FeatureCard({ title, description }) {
  return (
    <animate.div
      style={{
        opacity: 0,
        translateY: 50,
      }}
      view={{
        opacity: withTiming(1, { duration: 600 }),
        translateY: withSpring(0),
      }}
      viewOptions={{
        threshold: 0.3,
        once: true,
      }}
    >
      <h3>{title}</h3>
      <p>{description}</p>
    </animate.div>
  );
}

Best Practices​

✅ Do​

  • Use animate components for elements that need animation
  • Combine useValue with animate for programmatic animations
  • Use declarative props (hover, press, etc.) for simple interactions
  • Use transform properties (translateX, scale) instead of layout properties when possible

❌ Don't​

  • Don't use animate for static elements (use regular HTML elements)
  • Don't mix animated and non-animated styles unnecessarily
  • Don't animate layout properties (width, height, top, left) - use transforms instead
  • Don't forget to use Presence for exit animations

Performance Tips​

  1. Use transforms - translateX, translateY, scale, rotate are GPU-accelerated
  2. Avoid layout properties - Animating width, height, top, left causes reflows
  3. Batch updates - Update multiple properties in one object
  4. Use viewOptions.once - For view animations that should only run once
