useVelocity

useVelocity accepts a motion value and returns a new one that updates with the provided motion value's velocity.

const x = useMotionValue(0)
const xVelocity = useVelocity(x)
const scale = useTransform(
  xVelocity,
  [-3000, 0, 3000],
  [2, 1, 2],
  { clamp: false }
)

return <motion.div drag="x" style={{ x, scale }} />

Usage

Import useVelocity from Motion:

import { useVelocity } from "motion/react"

Pass any numerical motion value to useVelocity. It'll return a new motion value that updates with the velocity of the original value.

import { useMotionValue, useVelocity } from "framer-motion"

function Component() {
  const x = useMotionValue(0)
  const xVelocity = useVelocity(x)

  useMotionValueEvent(xVelocity, "change", latest => {
    console.log("Velocity", latestVelocity)
  })
  
  return <motion.div style={{ x }} />
}

Any numerical motion value will work. Even one returned from useVelocity.

const x = useMotionValue(0)
const xVelocity = useVelocity(x)
const xAcceleration = useVelocity(xVelocity)
