React Motion UI Pack

npm version Dependency Status CDNJS
React Motion is an amazing animation library for React. React Motion UI Pack tries to help ease entry level / common use cases with React Motion by providing a higher level way to work with it and create common UI transitions easier. If you need more complex animations I suggest using React Motion directly.


yarn add react-motion-ui-pack
npm install react-motion-ui-pack --save
<script src=""></script>
(UMD library exposed as `Transition`)


import Transition from 'react-motion-ui-pack'

// Animate a list of items as they are added
    opacity: 1,
    opacity: 0,
  { =>
      <li key={}>{item.content}</li>

// Animate a modal
  component={false} // don't use a wrapping component
    opacity: 1,
    translateY: spring(0, {stiffness: 400, damping: 10})
    opacity: 0,
    translateY: 250
  { this.state.modalOpen &&
    <div key="modal" className="modal__content">
      // modal code


component: PropTypes.oneOfType(PropTypes.string, PropTypes.bool, isElement)

Define the wrapping tag/component around the children passed in, pass false to not use a wrapping component at all for only child components.

runOnMount: PropTypes.bool

Determines whether the animation runs on mount or not

appear: PropTypes.object

Where the animation starts, defaults to leave value if nothing passed

enter: PropTypes.object

The resting state of the animation

leave: PropTypes.object

The ending value of the animation

onEnter: PropTypes.func

Callback right before an element enters, passes in your current animating values onEnter={currentValues => /* do something */} called only once.

onLeave: PropTypes.func

Same as onEnter, but fires multiple times as an element is leaving.


How appear, enter, & leave work

These values are automatically wrapped in a React Motion spring to keep the API simple. If you need a custom config you can pass your own spring e.g. spring(22, { stiffness: 30, damping: 300 }).

My animation values aren't being applied to any elements

If you decide to use a custom component as a child, style and dimensions props will be passed into that component for you to use however you want. If you pass a regular React DOM element, <Transition/> will take care of applying the values for you by cloning your element and passing it in.
