    React Easy Flip

    ⚛ A lightweight React library for smooth FLIP animations


    • Animates the unanimatable (DOM positions, mounts/unmounts)

    • One hook for many usecases

    • Uses the Web Animations API (WAAPI)

    • Stable and smooth 60fps animations

    • SSR-friendly

    • Built-in easing functions

    • Lightweight

    Previous README versions

    This is a README for v4. The v3 README can be found here.


    Repository: react-easy-flip-demo

    You can also read about how it works in detail here.


    npm install react-easy-flip@beta

    Get started

    1. Import useFlip hook and FlipProvider:
    import { useFlip, FlipProvider } from 'react-easy-flip'
    1. Wrap your app (or at least a component that contains animated children) with a FlipProvider
      <MyApp />
    1. Assign a data-flip-root-id to any parent of the element(s) you want to animate
    <div data-flip-root-id="flip-root">
    1. Pick a unique data-flip-id and assign it to the element(s) you want to animate. It can be the same as a key prop
    <img data-flip-id="animated-image" />
    1. Use the hook by passing it the root ID you picked in (3)

    And that's it!

    Usage details


    useFlip requires one argument, which is an ID of the root, i.e. any parent whose children you want to animate. You can optionally pass an options object with animation options (see details below) as a second argument. Third argument is the optional dependencies which you would normally pass to a useEffect hook: use it if you need to explicitly tell react-easy-flip that items you want to animate changed.

    useFlip(rootId, animationOptions, deps)

    Animation optons

    Animation options is an object.

    Property Default Required Type Details
    duration 400 false number Animation duration (ms)
    easing easeOutCubic false function Easing function (that can be imported from react-easy-flip)
    delay 0 false number Animation delay
    animateColor false false boolean Animate background color of the animated element


    import { easeInOutQuint } from 'react-easy-flip`
    const SomeReactComponent = () => {
      const animationOptions = {
        duration: 2000,
        easing: easeInOutQuint,
      useFlip(rootId, animationOptions)
      return (
        <div data-flip-root-id="root">
          <div data-flip-id="flipped" />

    Exported easings

    react-easy-flip exports ready-to-use easing functions. You can see the examples here.

    • linear
    • easeInSine
    • easeOutSine
    • easeInOutSine
    • easeInCubic
    • easeOutCubic
    • easeInOutCubic
    • easeInQuint
    • easeOutQuint
    • easeInOutQuint
    • easeInBack
    • easeOutBack
    • easeInOutBack

    AnimateInOut (experimental)

    While useFlip can animate all kinds of position changes, it does not animate mount/unmount animations (e.g. fade in/out). For this purpose the <AnimateInOut /> component is also exported. To use it, simple wrap with it the components/elements which you want to be animated. By default the initial render is not animated, but this can be changed with a prop.

    Every element wrapped with a <AnimateInOut /> must have a unique key prop.


    import { AnimateInOut } from 'react-easy-flip`
    const SomeReactComponent = () => {
      return (
            <div key="flipped-1" />
            <div key="flipped-2" />
            <div key="flipped-3" />

    Here are all props that you can pass to <AnimateInOut />:

    Property Default Required Type Details
    in fadeIn false AnimationKeyframes Mount animation options
    out fadeOut false AnimationKeyframes Unmount animation options
    playOnFirstRender false false boolean Animate on first render
    itemAmount undefined false number An explicit amount of current children (see explanation below)

    What is itemAmount for? In most cases this is not needed. But if your element is animated with a shared layout transition (such as moving from one list to another), this means that it doesn't need an unmount animation. In order to avoid two animations being applied to one element, provide the amount. For example, if this is a todo-app-like application, keep the number of both todo and done items. Moving from todo to done doesn't change the total amount of items, but <AnimateInOut /> does not know that until you tell it. See the recipes below.

    Comparison with other libraries

    • react-easy-flip uses Web Animations API (WAAPI) for animations. No other library based on a FLIP technique currently does that.

    • Similar to existing libraries such as react-overdrive, react-flip-move or react-flip-toolkit (although only the latter seems to be maintained).

    • Allows you to easily do so-called shared layout animations (e.g. smoothly move an element from one page/parent to another). Some examples are given below. This is what heavier libraries like framer-motion call Magic Motion.

    • Additionally, react-easy-flip is the only lightweight FLIP library for React that provides animation via a hook. Currently react-easy-flip has the smallest bundle size. It also does not use React class components and lifecycle methods that are considered unsafe in latest releases of React.


    List sort/shuffle animation

    Go to code

    simple shuffle animation

    Both x and y coordinate shuffle

    Go to code

    auto shuffle animation

    Shared layout animation

    This is an todo-app-like example of shared layout animations. Click on any rectangle to move it to another parent. Note that on every click an item is actually unmounted from DOM and re-mounted in the other position, but having the same data-flip-id allows to be smoothly animated from one to another position.

    Go to code

    shared layout  animation

    Shared layout animation (navigation)

    One nice usecase for shared layout animation is navigation bars where we want to move the highlighting indicator smoothly between tabs.

    Go to code

    shared layout  animation

    In/out (mount/unmount) animation (opacity)

    The fade in and out keyframes are default and work out of box (= you do not need to explicitly pass them).

    Go to code

    shared layout  animation

    In/out (mount/unmount) animation (translation)

    An example of passing custom animation options to <AnimateInOut>. Here the images are moved in and out instead of simply fading in and out.

    This library requires React version 16.8.0 or higher (the one with Hooks).
