Stagger Effects

The react-flip-toolkit library offers spring-driven stagger configurations so that you can achieve complex sequenced effects.

For the most basic stagger effect, you can simply add a stagger boolean prop to your Flipped element:

<Flipped flipId={`element-${i}`} stagger>
animation for the selected state of a list item

Spring Customizations

react-flip-toolkit uses springs for animations. To customize the spring, you can pass in a preset name:

// spring preset can be one of: "stiff", "noWobble", "gentle", "veryGentle", or "wobbly"
<Flipper flipKey='foo' spring='wobbly'>
  {/* Flipped components go here...*/}

or a custom spring config:

<Flipper flipKey='foo' spring={{ stiffness: 280, damping: 22 }} >
  {/* Flipped components go here...*/}

Nested Scale Transforms

stripe menu

Interesting animations often involve scale transforms in addition to simple translate transforms. The problem with scale animations has to do with children — if you scale a div up 2x, you will warp any children it has by scaling them up too, creating a weird-looking animation. That's why this library allows you to wrap the child with a Flipped component that has an inverseFlipId to counteract the transforms of the parent:

<Flipped flipId={id}>
    <Flipped inverseFlipId={id} scale>
      <div>some text that will not be warped</div>

By default, both the scale and the translation transforms of the parent will be counteracted (this allows children components to make their own FLIP animations without being affected by the parent). But for many use cases, you'll want to additionally specify the scale prop to limit the adjustment to the scale and allow the positioning to move with the parent.

Note: the DOM element with the inverse transform should lie flush against its parent container for the most seamless animation.

That means any layout styles — padding, flexbox, etc—should be applied to the inverted container (the element wrapped with a Flipped component with an inverseFlipId) rather than the parent Flipped container.

Route-based Animations With React Router

Fork Github repo

react-flip-toolkit works great with client-side routers to provide route-driven transitions:

  render={({ location, search }) => {
    return (
      {/* Child routes that contain Flipped components go here...*/}

The Components


The parent wrapper component that contains all the elements to be animated. You'll often need only one of these per page, but sometimes it will be more convenient to have multiple Flipper regions of your page concerned with different transitions.

<Flipper flipKey={someKeyThatChanges}>{/* children */}</Flipper>

Basic Props

prop default type details
flipKey (required) - string, number, bool Changing this tells react-flip-toolkit to transition child elements wrapped in Flipped components.
children (required) - node One or more element children
spring noWobble string or object Provide a string referencing one of the spring presets — noWobble (default), veryGentle, gentle, wobbly, or stiff, OR provide an object with stiffness and damping parameters. Explore the spring setting options here.. The prop provided here will be the spring default that can be overrided on a per-element basis on the Flipped component.
applyTransformOrigin true bool Whether or not react-flip-toolkit should apply a transform-origin of "0 0" to animating children (this is generally, but not always, desirable for FLIP animations)
element div string If you'd like the wrapper element created by the Flipped container to be something other than a div, you can specify that here.
className - string A class applied to the wrapper element, helpful for styling.
staggerConfig - object Provide configuration for staggered Flipped children. The config object might look something like the code snippet below:
  // the "default" config will apply to staggered elements without explicit keys
      default: {
        // default direction is forwards
        reverse: true,
        // default is .1, 0 < n < 1
        speed: .5
  // this will apply to Flipped elements with the prop stagger='namedStagger'
    namedStagger : { speed: .2 }

Advanced Props

prop default type details
decisionData - any Sometimes, you'll want the animated children of Flipper to behave differently depending on the state transition — maybe only certain Flipped elements should animate in response to a particular change. By providing the decisionData prop to the Flipper component, you'll make that data available to the shouldFlip and shouldInvert methods of each child Flipped component, so they can decided for themselves whether to animate or not.
debug false boolean This experimental prop will pause your animation right at the initial application of FLIP-ped styles. That will allow you to inspect the state of the animation at the very beginning, when it should look similar or identical to the UI before the animation began.
portalKey - string In general, the Flipper component will only apply transitions to its descendents. This allows multiple Flipper elements to coexist on the same page, but it will prevent animations from working if you use portals. You can provide a unique portalKey prop to Flipper to tell it to scope element selections to the entire document, not just to its children, so that elements in portals can be transitioned.
onComplete - function This callback prop will be called when all individual FLIP animations have completed. Its single argument is a list of flipIds for the Flipped components that were activated during the animation. If an animation is interrupted, onComplete will be still called right before the in-progress animation is terminated.
handleEnterUpdateDelete - function By default, react-flip-toolkit finishes animating out exiting elements before animating in new elements, with updating elements transforming immediately. You might want to have more control over the sequence of transitions — say, if you wanted to hide elements, pause, update elements, pause again, and finally animate in new elements. Or you might want transitions to happen simultaneously. If so, provide the function handleEnterUpdateDelete as a prop. The best way to understand how this works is to check out this interactive example. handleEnterUpdateDelete receives the following arguments every time a transition occurs:
  // this func applies an opacity of 0 to entering elements so
  // they can be faded in - it should be called immediately
  // calls `onAppear` for all entering elements
  //calls `onExit` for all exiting elements
  // returns a promise that resolves when all elements have exited
  // the main event: `FLIP` animations for updating elements
  // this also returns a promise that resolves when
  // animations have completed


Wraps an element that should be animated.

E.g. in one component you can have

<Flipped flipId="coolDiv">
  <div className="small" />

and in another component somewhere else you can have

<Flipped flipId="coolDiv">
  <div className="big" />

and they will be tweened by react-flip-toolkit.

The Flipped component produces no markup, it simply passes some props down to its wrapped child.

Wrapping a React Component

If you want to wrap a React component rather than a JSX element like a div, you can provide a render prop and then apply the flippedProps directly to the wrapped element in your component:

  {flippedProps => <MyCoolComponent flippedProps={flippedProps} />}
const MyCoolComponent = ({ flippedProps }) => <div {...flippedProps} />

You can also simply provide a regular React component as long as that component spreads unrecognized props directly onto the wrapped element (this technique works well for wrapping styled components):

  <MyCoolComponent />
const MyCoolComponent = ({ knownProp, ...rest }) => <div {...rest} />

Basic props

prop default type details
children (required) - node or function Wrap a single element, React component, or render prop child with the Flipped component
flipId (required unless inverseFlipId is provided) - string Use this to tell react-flip-toolkit how elements should be matched across renders so they can be animated.
inverseFlipId - string Refer to the id of the parent Flipped container whose transform you want to cancel out. If this prop is provided, the Flipped component will become a limited version of itself that is only responsible for cancelling out its parent transform. It will read from any provided transform props and will ignore all other props (besides inverseFlipId.) Read more about canceling out parent transforms here.
transformOrigin "0 0" string This is a convenience method to apply the proper CSS transform-origin to the element being FLIP-ped. This will override react-flip-toolkit's default application of transform-origin: 0 0; if it is provided as a prop.
spring noWobble string or object Provide a string referencing one of the spring presets — noWobble (default), veryGentle, gentle, wobbly, or stiff, OR provide an object with stiffness and damping parameters. Explore the spring setting options here.
stagger false boolean or string Provide a natural, spring-based staggering effect in which the spring easing of each item is pinned to the previous one's movement. Provide true to stagger the element with all other staggered elements. If you want to get more granular, you can provide a string key and the element will be staggered with other elements with the same key.
delayUntil false string (flipId) Delay an animation by providing a reference to another Flipped component that it should wait for before animating (the other Flipped component should have a stagger delay as that is the only use case in which this prop is necessary.)

Callback props

animation of a sentence transforming into another sentence

The above animation uses onAppear and onExit callbacks for fade-in and fade-out animations.

prop arguments details
onAppear element, index, {previous: decisionData, current: decisionData } Called when the element first appears in the DOM. It is provided a reference to the DOM element being transitioned as the first argument, and the index of the element relative to all appearing elements as the second. Note: If you provide an onAppear prop, the default opacity of the element will be set to 0 to allow you to animate it in without any initial flicker. If you don't want any opacity animation, just set the element's opacity to 1 immediately in your onAppear function.
onStart element, {previous: decisionData, current: decisionData } Called when the FLIP animation for the element starts. It is provided a reference to the DOM element being transitioned as the first argument.
onStartImmediate element, {previous: decisionData, current: decisionData } Similar to onStart, but guaranteed to run for all FLIP-ped elements on the initial tick of the FLIP animation, before the next frame has rendered, even if the element in question has a stagger delay. It is provided a reference to the DOM element being transitioned as the first argument.
onSpringUpdate springValue Called with the current spring value (normally between 0 - 1 but might briefly go over or under that range depending on the level of "bounciness" of the spring). Useful if you'd like to tween other, non-FLIP animations in concert with a FLIP transition.
onComplete element,{previous: decisionData, current: decisionData } Called when the FLIP animation completes. It is provided a reference to the DOM element being transitioned as the first argument. (If transitions are interruped by new ones, onComplete will still be called.)
onExit element, index, removeElement, {previous: decisionData, current: decisionData } Called when the element is removed from the DOM. It must call the removeElement function when the exit transition has completed.

Transform props

By default the FLIP-ped elements' translate, scale, and opacity properties are all transformed. However, certain effects require more control so if you specify any of these props, only the specified attribute(s) will be tweened:

prop type details
translate bool Tween translateX and translateY
scale bool Tween scaleX and scaleY
opacity bool

Advanced props

Functions to control when FLIP happens

prop arguments details
shouldFlip previousDecisionData, currentDecisionData A function provided with the current and previous decisionData props passed down by the Flipper component. Returns a boolean to indicate whether a Flipped component should animate at that particular moment or not.
shouldInvert previousDecisionData, currentDecisionData A function provided with the current and previous decisionData props passed down by the Flipper component. Returns a boolean indicating whether to apply inverted transforms to all Flipped children that request it via an inverseFlipId.


As a convenience, react-flip-toolkit exports a tiny function to access the same spring system used to create FLIP transitions.

Library details

  • Tested in latest Chrome, Firefox, Safari, Edge, and IE 11 with Browserstack.
  • For IE11 compatability, make sure you're polyfilling the window.Promise object.
  • Requires React 16+
  • Uses Rematrix for matrix calculations and a simplified fork of Rebound for spring animations


Problem #1: Nothing is happening

  • Make sure you're updating the flipKey attribute in the Flipper component whenever an animation should happen.
  • If one of your Flipped components is wrapping another React component rather than a DOM element, use a render prop to get the Flipped props and pass down to the necessary DOM element.
  • Is the element that's receiving props from Flipped visible in the DOM? react-flip-toolkit attempts to optimize performance by not animating elements that are off-screen or elements that have no width or height.
  • display:inline elements cannot be animated. If you want an inline element to animate, set display:inline-block.

Problem #2: Things look weird / animations aren't behaving

  • Check to make sure all flipIds are unique. At any point, there can only be one element with a specified flipId on the page. If there are multiple Flipped elements on the page with the same id, the animation will break.
  • Make sure you are animating the element you want to animate and not, for instance, a wrapper div. If you are animating an inline element like some text, but have wrapped it in a div, you're actually animating the div, which might have a much wider width that you'd expect at certain points, which will throw off the animation. Check to see if you need to add an inline-block style to the animated element.
  • Make sure you don't have any competing CSS transitions on the element in question.
  • If you are animating an image, try giving the image hard-coded dimensions and seeing if that fixes the problem. (If you are relying on the innate dimensions of the image, it might not have been fully rendered by the browser in time for the new image dimensions to be measured.)

Problem #3: It's still not working

  • Try out the debug prop. If you still can't figure out what's going wrong, you can add the the debug prop directly on your Flipper component to pause transitions at the beginning.
  • If you think something might actually be broken, or are completely stuck, feel free to make an issue.


React-flip-toolkit does a lot of work under the hood to try to maximize the performance of your animations — for instance, off-screen elements won't be animated, and style updates are batched to prevent layout thrashing. However, if you are building particularly complex animations—ones that involve dozens of elements or large images— there are some additional strategies you can use to ensure performant animations.


When you trigger a complex FLIP animation with react-flip-toolkit, React could be spending vital milliseconds doing unnecessary reconciliation work before allowing the animation to start. If you notice a slight delay between when the animation is triggered, and when it begins, this is probably the culprit. To short-circuit this possibly unnecessary work, try memoizing your component by using React.memo or PureComponent for your animated elements, and seeing if you can refactor your code to minimize prop updates to animated children when an animation is about to occur.


.box {
  will-change: transform;

This CSS property tells the browser to anticipate changes to an element. It should be used with caution, because it can increase browser resource usage. If you notice rendering issues in your animation, I would recommend trying it out and seeing if it increases the performance of the animation.
