# Animation

Material in motion is responsive and natural. Use these easing curves and duration patterns to create smooth and consistent motion.

## Installation

```
npm install @limetech/mdc-animation
```

## Usage

### Sass Variables

We provide timing functions which you can use with the `animation` or `transition` CSS properties

```scss
@import "@limetech/mdc-animation/variables";

.my-element--animating {
  animation: foo-keyframe 175ms $mdc-animation-standard-curve-timing-function;
}
```

Variable | Description
--- | ---
`mdc-animation-deceleration-curve-timing-function` | Timing function to decelerate
`mdc-animation-standard-curve-timing-function` | Timing function to quickly accelerate and slowly decelerate
`mdc-animation-acceleration-curve-timing-function` | Timing function to accelerate
`mdc-animation-sharp-curve-timing-function` | Timing function to quickly accelerate and decelerate

The following functions create transitions given `$name` and the `$duration`. You can also specify `$delay`, but the default is 0ms. `$name` can either refer to the keyframe, or to CSS property used in `transition`.

```scss
@import "@limetech/mdc-animation/functions";

.my-element {
  transition: mdc-animation-exit-permanent(/* $name: */ opacity, /* $duration: */ 175ms, /* $delay: */ 150ms);
  opacity: 0;
  will-change: opacity;

  &--animating {
    transition: mdc-animation-enter(/* $name: */ opacity, /* $duration: */ 175ms);
    opacity: 1;
  }
}
```


```scss
@import "@limetech/mdc-animation/functions";

@keyframes fade-in {
  from {
    transform: translateY(-5rem);
    opacity: 0;
  }

  to {
    transform: translateY(0);
    opacity: 1;
  }
}

.my-element {
  animation: mdc-animation-enter(/* $name: */ fade-in, /* $duration: */ 350ms);
}
```

Function | Description
--- | ---
`mdc-animation-enter($name, $duration, $delay)` | Defines transition for entering the frame
`mdc-animation-exit-permanent($name, $duration, $delay)` | Defines transition for exiting the frame permanently
`mdc-animation-exit-temporary($name, $duration, $delay)` | Defines transition for exiting the frame temporarily

### JavaScript

These functions handle prefixing across various browsers

```js
import {getCorrectEventName} from '@limetech/mdc-animation';

const eventToListenFor = getCorrectEventName(window, 'animationstart');
```

Method Signature | Description
--- | ---
`getCorrectEventName(windowObj: Window, eventType: StandardJsEventType) => StandardJsEventType \| PrefixedJsEventType` | Returns a JavaScript event name, prefixed if necessary. See [`types.ts`](types.ts) for supported values.
`getCorrectPropertyName(windowObj: Window, cssProperty: StandardCssPropertyName) => StandardCssPropertyName \| PrefixedCssPropertyName` | Returns a CSS property name, prefixed if necessary. See [`types.ts`](types.ts) for supported values.
