Pros of Motion

• More intuitive API with a declarative approach
• Built-in support for gestures and drag interactions
• Comprehensive documentation and examples

Cons of Motion

• Larger bundle size
• Limited support for complex physics-based animations

Code Comparison

Motion:

<motion.div
  initial={{ opacity: 0 }}
  animate={{ opacity: 1 }}
  transition={{ duration: 0.5 }}
>
  Hello World
</motion.div>

React Spring:

import { useSpring, animated } from 'react-spring'

const props = useSpring({ opacity: 1, from: { opacity: 0 } })
return <animated.div style={props}>Hello World</animated.div>

Key Differences

• Motion uses a more declarative approach, while React Spring relies on hooks
• Motion offers built-in gesture support, whereas React Spring requires additional libraries
• React Spring provides more fine-grained control over physics-based animations
• Motion has a larger ecosystem and more comprehensive documentation
• React Spring has a smaller bundle size and may be more suitable for performance-critical applications

Both libraries are powerful tools for creating animations in React applications, with Motion offering a more user-friendly approach and React Spring providing more flexibility for complex animations.

Pros of react-animations

• Simpler API, easier to learn and implement for basic animations
• Lightweight and focused solely on CSS animations
• Compatible with any CSS-in-JS library

Cons of react-animations

• Limited to predefined keyframe animations
• Less flexible for complex, dynamic animations
• No built-in support for spring physics or advanced timing functions

Code Comparison

react-animations:

import { fadeIn } from 'react-animations';
import styled, { keyframes } from 'styled-components';

const fadeInAnimation = keyframes`${fadeIn}`;
const FadeInDiv = styled.div`animation: 1s ${fadeInAnimation};`;

react-spring:

import { useSpring, animated } from 'react-spring';

const props = useSpring({ opacity: 1, from: { opacity: 0 } });
return <animated.div style={props}>I will fade in</animated.div>;

react-spring offers a more dynamic and flexible approach, allowing for complex animations with physics-based spring animations. It provides better performance for continuous animations and supports interruptions and changes mid-animation. react-animations, on the other hand, is simpler to use for basic CSS keyframe animations but lacks the advanced features and flexibility of react-spring. Choose react-animations for straightforward, predefined animations, and react-spring for more complex, interactive, and performance-critical animations.

Pros of react-motion

• Simpler API with fewer concepts to learn
• More predictable and consistent animations
• Better performance for complex animations due to its approach

Cons of react-motion

• Less flexible than react-spring for certain types of animations
• Steeper learning curve for beginners
• Limited built-in animation types compared to react-spring

Code Comparison

react-motion:

<Motion defaultStyle={{x: 0}} style={{x: spring(10)}}>
  {({x}) => <div style={{transform: `translateX(${x}px)`}} />}
</Motion>

react-spring:

const props = useSpring({from: {x: 0}, to: {x: 10}})
return <animated.div style={{transform: props.x.interpolate(x => `translateX(${x}px)`)}} />

Both libraries provide ways to create smooth animations in React applications. react-motion focuses on physics-based animations with a more opinionated approach, while react-spring offers greater flexibility and a wider range of animation types. react-spring has gained more popularity in recent years due to its versatility and easier integration with modern React practices. However, react-motion may still be preferred for specific use cases where its approach to animations is more suitable.

Pros of react-spring

• Mature and widely adopted animation library for React
• Extensive documentation and community support
• Flexible API supporting various animation styles

Cons of react-spring

• Larger bundle size compared to newer alternatives
• Learning curve for complex animations
• Performance overhead for simpler animations

Code Comparison

react-spring:

import { useSpring, animated } from 'react-spring'

function AnimatedComponent() {
  const props = useSpring({ opacity: 1, from: { opacity: 0 } })
  return <animated.div style={props}>I will fade in</animated.div>
}

react-spring:

import { useSpring, animated } from 'react-spring'

function AnimatedComponent() {
  const props = useSpring({ opacity: 1, from: { opacity: 0 } })
  return <animated.div style={props}>I will fade in</animated.div>
}

Note: The code comparison shows identical usage as both repositories refer to the same project. The react-spring library is maintained under the pmndrs organization on GitHub, and there is no separate repository with a different implementation.

Pros of Anime

• Lightweight and fast, with a small file size
• Works with any JavaScript environment, not limited to React
• Supports a wide range of animation types, including SVG animations

Cons of Anime

• Less integrated with React ecosystem
• May require more manual setup for complex animations in React applications
• Doesn't provide built-in hooks or components for React integration

Code Comparison

Anime:

anime({
  targets: '.element',
  translateX: 250,
  rotate: '1turn',
  duration: 800,
  easing: 'easeInOutQuad'
});

React Spring:

import { useSpring, animated } from 'react-spring';

const props = useSpring({ x: 250, rotation: 360 });
return <animated.div style={{ transform: props.x.interpolate(x => `translateX(${x}px) rotate(${props.rotation.value}deg)`) }} />;

React Spring offers a more declarative approach within React components, while Anime provides a simpler API that can be used in any JavaScript context. React Spring's integration with React's lifecycle and state management can be advantageous for complex React applications, whereas Anime's flexibility makes it suitable for a broader range of projects.
