A React hook for animating components when they are mounted and unmounted (added to / removed from React tree).



  • Uses Web Animation API (60fps animation off main thread)
  • Spring physics based animation
  • Cancelable / reversable animations
  • Chainable mounts / unmounts
  • Small (~1KB)

Get started

Basic usage

import { useAnimatePresence } from "use-animate-presence";

const variants = {
  x: { from: -800, to: 0 },

export default function App() {
  const animatedDiv = useAnimatePresence({
    initial: "visible",

  return (
      <button onClick={() => animatedDiv.togglePresence()}>Toggle</button>
      {animatedDiv.isRendered && <div ref={animatedDiv.ref} />}

Advanced usage

useAnimatePresence takes one object as an argument. Below is a table with possible properties and their description (some properties are explained in detail later):

Property Default Required Type Details
variants - true object Properties and values to animate
initial - true "hidden" | "visible" Whether item is rendered initially
animateFirstRender true false boolean Whether to animate on first render (first mount)
enter undefined false function Function to execute when enter animation is finished
exit undefined false function Function to execute when exit animation is finished
wait undefined false function Function to execute both when enter and when exit animation is finished
debugName "unknown" false string Name for tracking the animation lifecycle of the hook
duration 1000 false number Animation duration (ms) (use if you only animate opacity)
options (read below) false object Spring options (stiffness, mass and damping ratio)

Return value

useAnimatePresence returns an object which contains a function that can toggle presence, a ref that you need to attach to the element you want to animate and a isRendered property which you can use to conditionally render elements.

Property Details
ref React ref
togglePresence Function that toggles presence (and animates)
isRendered Boolean that should be used to conditionally render elements

Look again at the example above to see how all properties are used:

return (
    <button onClick={() => animatedDiv.togglePresence()}>Toggle</button>
    {animatedDiv.isRendered && <div ref={animatedDiv.ref} />}


Variants look like this:

const variants = {
  x: { from: -800, to: 0 },
  deg: 360,

Except for deg, which is degrees of rotation, every property must have a from value and a to value. All possible properties are: x, y, deg, opacity and scale (scale is experimental and might not work as intended).

enter, exit and wait

These are callbacks to be executed after enter (mount) or exit (unmount) animation finishes. wait is simply a shorthand - if you need to execute the same callback on both enter and exit animations you can just pass it as a wait property. Mostly, you will need this to chain mounts / unmounts. For example, if you want element B to animate only after element A is finished, you can do this:

const elementA = useAnimatePresence({
  variants: springVariants,
  initial: "hidden",
  debugName: "front-square",

const elementB = useAnimatePresence({
  variants: springVariants,
  initial: "visible",
  wait: elementA.togglePresence,

return (
    {<button onClick={() => elementB.togglePresence()}>Toggle</button>}
    {elementB.isRendered && (
      <div ref={elementB.ref}>
        {elementA.isRendered && <div ref={elementA.ref} />}

In this example, elementA will not be animated and its property isRendered will be false until elementB is finished animating. Play with a complex example here:

Spring options

Springs have stiffness, mass and damping ratio. The defaults are: stiffness 150, mass 3 and damping 27. You can customize the parameters like this:

  initial: "visible",
  options: {
    stiffness: 500,
    mass: 1,
    damping: 10,


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