npm install react-animation-components

Make sure you also have installed the following peer dependencies:

    "react": "^16.0.0",
    "react-dom": "^16.0.0",
    "react-transition-group": "^2.2.1",
    "prop-types": "^15.6.0"

Animation Components

Props available on all animation components

The following are available on any animation component as well as any valid Transition props. Transitions are set to appear and their timeout is calculated by combining the delay and duration by default but can be overwritten.

Key	Description	Example	Type	Default Value
className	Passes className to wrapper div	some-class	string	undefined
delay	Sets the animations transitionDelay	500	number	0
duration	Sets the animations transitionDuration	1000	number	500
style	Passes styles to wrapper div	{ display:'flex' }	object	{}
timingFn	Sets the animations transitionTimingFunction	'ease-in-out'	string	'ease'

Fade

Transitions the wrapped element's opacity from one value to another

Props

Key	Description	Example	Type	Default Value
enterOpacity	The opacity value when in is true	0.85	number	0
exitOpacity	The opacity value when in is false	0.25	number	0

Examples

import { Fade } from 'react-animation-components'

<Fade in>
  <h1>I'm transitioning to opacity:1</h1>
</Fade>

<Fade in enterOpacity={0.85}>
  <h1>I'm transitioning to opacity:0.85</h1>
</Fade>

<Fade in={false}>
  <h1>I'm transitioning to opacity:0</h1>
</Fade>

<Fade in={false} exitOpacity={0.25}>
  <h1>I'm transitioning to opacity:0.25</h1>
</Fade>

Transform

Transitions the wrapped element from one transform property to another. Any valid transform property will work.

Props

Key	Description	Example	Type	Default Value
enterTransform	The transform value when in is true	'translateX(100px)'	string	'none'
exitTransform	The transform value when in is false	'translateX(100px)'	string	'none'

Examples

import { Transform } from 'react-animation-components'

<Transform enterTransform="translateX(100px)" in>
  <h1>I'm transitioning from my initial position to 100px right when `in` is `true`</h1>
</Transform>

<Transform enterTransform="translateX(100px)" exitTransform="translateX(-100px)" in>
  <h1>
    I'm 100px to the left of my initial position and
    I transition 100px right of my initial when `in` is `true`
  </h1>
</Transform>

<Transform enterTransform="rotate(90deg)" in>
  <h1>I transition from initial positon to rotate 90deg when `in` is `true`</h1>
</Transform>

FadeTransform

Composes Fade and Transform. All top level props are passed to both components. You can also pass props to individual components in the composition.

Props passed to indivudal components via fadeProps or transformProps will override any top level props

Props

Key	Description	Example	Type	Default Value
fadeProps	The props that only Fade recieves.	{ enterOpacity: 0.85 }	object	{}
transformProps	The props that only Transform recieves.	{ enterTransform: 'translateX(100px)' }	object	{}

Examples

import { FadeTransform } from 'react-animation-components'

<FadeTransform in transformProps={{ enterTransform: 'translateX(100px)' }}>
  <h1>I'm transitioning from my initial position to 100px right when `in` is `true`</h1>
</FadeTransform>

<FadeTransform
    in
    transformProps={{
        enterTransform: 'translateX(100px)',
        exitTransform: 'translateX(-100px)'
    }}
>
  <h1>
    I'm 100px to the left of my initial position and
    I transition 100px right of my initial when `in` is `true`
  </h1>
</FadeTransform>

<FadeTransform
    in
    transformProps={{
        exitTransform: 'translateX(-100px)'
    }}
    fadeProps={{
        enterOpacity: 0.85,
    }}
>
  <h1>I transition from `-100px` horizontally of my initial positon and to 0.85 opacity when `in` is `true`</h1>
</FadeTransform>

Wrapper Components

Wrapper components use the inner animation components onEntered and onExited. Setting those callbacks inside these wrappers will not work

Stagger

Uses TransitionGroup to stagger delay on a set of animation components

Props

Key	Description	Example	Type	Default Value
chunk	Used to limit the stagger into "chunks".	5	number	0
delay	The amount to separate each stagger by	1000	number	100
duration	A value to set the inner child animations transition duration	800	number	500
in	A boolean to tell the children to mount or unmount	true	boolean	false
onComplete	A function that is called after the last animation finishes	any valid function	function	Function.prototype(noop)
reverse	A boolean to tell the component to reverse how delays are applied	true	boolean	false

Examples

import { Fade, Stagger } from 'react-animation-components'

const items = ['first', 'second', 'third', 'fourth', 'fifth'];

<Stagger in>
    {items.map(
        item => (
            <Fade>
                <h1>Each {item} will transition in with an incrementally larger delay than the previous</h1>
            </Fade>
        )
    )}
</Stagger>

<Stagger chunk={4} in>
    {items.map(
        item => (
            <Fade>
                <h1>
                  Each {item} will increment in segments of 4.
                  First is 0, Second is 100, Third is 200, Fourth is 0, fifth is 100, and so on
                </h1>
            </Fade>
        )
    )}
</Stagger>

Random

Uses TransitionGroup to randomize delay on a set of animation components

Props

Key	Description	Example	Type	Default Value
duration	A value to set the inner child animations transition duration	800	number	500
in	A boolean to tell the children to mount or unmount	true	boolean	false
maxDelay	Maximum delay possible	5000	number	1500
minDelay	Minimum delay possible	100	number	0
onComplete	A function that is called after the last animation finishes	any valid function	function	Function.prototype(noop)
reverse	A boolean to tell the component to reverse how delays are applied	true	boolean	false

Examples

import { Fade, Random } from 'react-animation-components'

const items = ['first', 'second', 'third', 'fourth', 'fifth'];

<Random in>
    {items.map(
        item => (
            <Fade>
                <h1>Each {item} will randomly FadeIn between 0 and 1500ms</h1>
            </Fade>
        )
    )}
</Random>

<Random minDelay={1000} maxDelay={5000} in>
    {items.map(
        item => (
            <Fade>
                <h1>Each {item} will randomly FadeIn between 1000ms and 5000ms</h1>
            </Fade>
        )
    )}
</Random>

Loop

Loops using the onEntered and onExited callbacks to toggle in on a single animation component.

Props

Key	Description	Example	Type	Default Value
in	Initializes the loop when true	true	bool	false
interval	Sets the interval to toggle in. Also sets the duration	1000	number	500
iterations	Maximum number of loops	5.5	number	Infinity
onComplete	Callback that is called when the iterations have been met. Waits an additional interval to ensure its called when the last iteration has completed	any valid function	function	Function.prototype(noop)
onIterate	Callback that is called with the current count each time the loop iterates. Count is incremented by 0.5	any valid function	function	Function.prototype(noop)

Examples

import { Fade, Loop } from 'react-animation-components'

<Loop in>
    <Fade>
        <h1>I will Fade in and out repeatedly on 500ms intervals</h1>
    </Fade>
</Loop>

<Loop in iterations={5.5}>
    <Fade>
        <h1>I will Fade in and out repeatedly on 500ms intervals 5.5 times</h1>
    </Fade>
</Loop>
