React Staggered Animation

Animates items with a delay between them.

Install

npm install react-staggered-animation --save

Usage

First, define some CSS that describes your animation.

.fade-enter {
  opacity: 0.01;
  transform: translateY(50px);
}

.fade-enter.fade-enter-active {
  transition: opacity 250ms ease-in;
  opacity: 1;
}

.fade-appear { opacity: 0.01; }
.fade-appear.fade-appear-active { opacity: 1; transition: opacity 250ms ease-in; }

.fade-leave {
  opacity: 1;
}

.fade-leave.fade-leave-active {
  opacity: 0.01;
  transition: opacity 100ms ease-in;
}

Then just add children.

<StaggeredAnimation delay={100} transitionName="fade">
  <h1>One</h1>
  <h1>Two</h1>
  <h1>Three</h1>
</StaggeredAnimation>

Under the hood StaggeredAnimation uses ReactCSSTransitionGroup. For more information on how to configure animations, see https://facebook.github.io/react/docs/animation.html.

Note: If you're using StaggeredAnimation with a custom component, that custom component should accept a className property and pass it on to its top level renderable element (div, span, etc...).

Premade Animations

It is possible to use premade animations such as animate.css. For instance, the example below uses the bounceInUp transition in animate.css.

const transition = {
  appear: 'animate_animated',
  appearActive: 'animate_bounceInUp',
};

<StaggeredAnimation delay={100} transitionName={transition}>
  <h1>One</h1>
  <h1>Two</h1>
  <h1>Three</h1>
</StaggeredAnimation>

API

children - React.PropTypes.node | Array (Required)

One or more children to animate.

delay - Number

Amount of time in milliseconds the animation should be staggered. For instance if this were 100, every 100ms the next child would begin its animation until there are no children left to animate.

duration - Number (Optional)

The duration of a single animation. This is required for cleaning up classes on animated elements once their animation is completed. If not specified the classes are not removed, however if you are just animating elements in (and not removing them) you can omit this property.

start - Number (Optional)

Delay to apply to all items. For instance if you have a delay of 100ms, and a start of 500ms, the first item will begin to animate at 500ms, the second at 600ms, etc...

className - String (Optional)

Optional className to pass on to the internal ReactCSSTransitionGroup wrapper element.
