What is @material/animation?
@material/animation is a utility package from Material Design Components (MDC) that provides a set of functions and constants to help create smooth and consistent animations. It is designed to be used with other MDC components to ensure that animations follow Material Design guidelines.
What are @material/animation's main functionalities?
Animation Curves
Provides predefined animation curves such as easeInOut, easeOut, and easeIn that can be used to create smooth transitions and animations.
const { easeInOut, easeOut, easeIn } = require('@material/animation');
// Example usage in a CSS-in-JS style object
const styles = {
transition: `all 250ms ${easeInOut}`
};
Animation Durations
Includes standard durations for animations, such as short, medium, and long, to ensure consistency across different components.
const { duration } = require('@material/animation');
// Example usage in a CSS-in-JS style object
const styles = {
transitionDuration: `${duration.standard}ms`
};
Keyframe Animations
Provides utility functions to handle keyframe animations and ensure compatibility across different browsers.
const { getCorrectEventName } = require('@material/animation');
// Example usage in JavaScript
const animationEndEvent = getCorrectEventName(window, 'animationend');
element.addEventListener(animationEndEvent, () => {
console.log('Animation ended');
});
Other packages similar to @material/animation
animejs
Anime.js is a lightweight JavaScript animation library with a simple, yet powerful API. It supports various types of animations including CSS properties, SVG, DOM attributes, and JavaScript objects. Compared to @material/animation, Anime.js offers a more extensive set of features and greater flexibility for complex animations.
gsap
GSAP (GreenSock Animation Platform) is a robust JavaScript library for high-performance animations. It is widely used for creating complex timelines and animations with precise control. GSAP provides more advanced features and customization options compared to @material/animation, making it suitable for more intricate animation needs.
velocity-animate
Velocity is an animation engine that combines the best of jQuery and CSS transitions. It offers a rich set of features for creating smooth animations and is known for its performance. While @material/animation focuses on Material Design guidelines, Velocity provides a more general-purpose solution for web animations.
Animation
Material in motion is responsive and natural. Use these easing curves and duration patterns to create smooth and consistent motion.
Design & API Documentation
Installation
npm install @material/animation
Usage
Sass Variables
We provide timing functions which you can use with the animation
or transition
CSS properties
@use "@material/animation";
.my-element--animating {
animation: foo-keyframe 175ms animation.$standard-curve-timing-function;
}
$deceleration-curve-timing-function | Timing function to decelerate |
$standard-curve-timing-function | Timing function to quickly accelerate and slowly decelerate |
$acceleration-curve-timing-function | Timing function to accelerate |
$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. $name
can either refer to the keyframe, or to CSS property used in transition
.
@use "@material/animation";
.my-element {
transition: animation.exit-permanent( opacity, 175ms, 150ms);
opacity: 0;
will-change: opacity;
&--animating {
transition: animation.enter( opacity, 175ms);
opacity: 1;
}
}
@use "@material/animation";
@keyframes fade-in {
from {
transform: translateY(-80px);
opacity: 0;
}
to {
transform: translateY(0);
opacity: 1;
}
}
.my-element {
animation: animation.enter( fade-in, 350ms);
}
enter($name, $duration, $delay) | Defines transition for entering the frame |
exit-permanent($name, $duration, $delay) | Defines transition for exiting the frame permanently |
exit-temporary($name, $duration, $delay) | Defines transition for exiting the frame temporarily |
JavaScript
These functions handle prefixing across various browsers
import {getCorrectEventName} from '@material/animation';
const eventToListenFor = getCorrectEventName(window, 'animationstart');
getCorrectEventName(windowObj: Window, eventType: StandardJsEventType) => StandardJsEventType | PrefixedJsEventType | Returns a JavaScript event name, prefixed if necessary. See types.ts for supported values. |
getCorrectPropertyName(windowObj: Window, cssProperty: StandardCssPropertyName) => StandardCssPropertyName | PrefixedCssPropertyName | Returns a CSS property name, prefixed if necessary. See types.ts for supported values. |
