## What it does

The skill walks through the 12 Disney animation principles and pairs each with React Spring code. Squash and stretch, anticipation, staging, follow through, slow in and slow out, arc, exaggeration — all built on `useSpring` and its config. The examples carry real values for `tension` and `friction`, so you can lift the snippet straight into a component.

It goes past `useSpring`. There's `useTrail` for staggered list reveals, plus `useSprings`, `useChain` and `useTransition` for mount and unmount. A timing section covers the `gentle`, `stiff`, `slow` and `molasses` presets along with fast, normal, slow and wobbly configs. The rule it teaches: high `tension` with low `friction` snaps, low `tension` with high `friction` drifts.

This assumes a React project that already has React Spring installed. Without the library the snippets won't run, so add it first. Cursor and Codex read the file from `.cursor/skills/react-spring/SKILL.md` and `.agents/skills/react-spring/SKILL.md`; Claude reads `~/.claude/skills/react-spring/SKILL.md`.

## Install

### Claude Code (native platform)

```bash
npx skills add dylantarre/animation-principles --skill react-spring -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/react-spring/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dylantarre/animation-principles react-spring
```

2. **Manually: put the files in place**
- File: `.github/skills/react-spring/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill react-spring -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dylantarre/animation-principles --path skills/09-by-tool-framework/react-spring
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/react-spring/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dylantarre/animation-principles --skill react-spring -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dylantarre/animation-principles/tree/HEAD/skills/09-by-tool-framework/react-spring/SKILL.md

## When to use it
- build squash and stretch on springs instead of CSS keyframes
- add a wind-up before a jump with anticipation
- separate a hero element from the background with staging
- stagger a list reveal using useTrail
- pick tension and friction values for the speed you want

## Example prompts
- show me squash and stretch with useSpring
- I need a wind-up before the jump — anticipation example in React Spring
- stagger these cards with useTrail

# React Spring Animation Principles

Implement all 12 Disney animation principles using React Spring's spring physics system.

## 1. Squash and Stretch

```jsx
const [springs, api] = useSpring(() => ({
  scaleX: 1,
  scaleY: 1,
  config: { tension: 300, friction: 10 }
}));

api.start({ scaleX: 1.2, scaleY: 0.8 });
<animated.div style={springs} />
```

## 2. Anticipation

```jsx
const [props, api] = useSpring(() => ({ y: 0, scaleY: 1 }));

const jump = async () => {
  await api.start({ y: 10, scaleY: 0.9 }); // wind up
  api.start({ y: -200, config: { tension: 200 } }); // action
};
```

## 3. Staging

```jsx
const bgSpring = useSpring({ filter: 'blur(3px)', opacity: 0.6 });
const heroSpring = useSpring({ scale: 1.1, zIndex: 10 });
```

## 4. Straight Ahead / Pose to Pose

```jsx
const [props] = useSpring(() => ({
  from: { x: 0, y: 0 },
  to: [
    { x: 100, y: -50 },
    { x: 200, y: 0 },
    { x: 300, y: -30 }
  ]
}));
```

## 5. Follow Through and Overlapping Action

```jsx
const bodySpring = useSpring({ x: 200 });
const hairSpring = useSpring({ x: 200, delay: 50 });
const capeSpring = useSpring({ x: 200, delay: 100, config: { friction: 15 } });
```

## 6. Slow In and Slow Out

```jsx
const spring = useSpring({
  x: 300,
  config: {
    tension: 170,
    friction: 26 // balanced = smooth in/out
  }
});
// High tension + low friction = fast
// Low tension + high friction = slow
```

## 7. Arc

```jsx
const [props] = useSpring(() => ({
  to: async (next) => {
    await next({ x: 100, y: -100 });
    await next({ x: 200, y: 0 });
  },
  config: { tension: 200, friction: 20 }
}));
```

## 8. Secondary Action

```jsx
const buttonSpring = useSpring({ scale: hover ? 1.05 : 1 });
const iconSpring = useSpring({
  rotate: hover ? 15 : 0,
  delay: 50
});
```

## 9. Timing

```jsx
const configs = {
  fast: { tension: 400, friction: 30 },
  normal: { tension: 170, friction: 26 },
  slow: { tension: 100, friction: 40 },
  wobbly: { tension: 180, friction: 12 }
};
// Or use presets: config.gentle, config.stiff, config.slow
```

## 10. Exaggeration

```jsx
const spring = useSpring({
  scale: 1.5,
  rotate: 720,
  config: { tension: 200, friction: 8 } // low friction = overshoot
});
```

## 11. Solid Drawing

```jsx
const spring = useSpring({
  transform: 'perspective(1000px) rotateX(45deg) rotateY(30deg)'
});
```

## 12. Appeal

```jsx
const cardSpring = useSpring({
  scale: hover ? 1.02 : 1,
  boxShadow: hover
    ? '0 20px 40px rgba(0,0,0,0.2)'
    : '0 5px 15px rgba(0,0,0,0.1)',
````
