A React hook for tracking the position, hover, and "down" state of the mouse as it interacts with an element. This hook provides interoperability between touch and desktop devices and will treat ontouch events the same as onmouse ones. Additionally, this hook is throttled to 30fps by default using a useThrottle() hook, though the precise frame rate is configurable.

Quick Start

Check out the example on CodeSandbox

import * as React from 'react'
import useMouse from '@react-hook/mouse-position'

const Component = (props) => {
  const ref = React.useRef(null)
  const mouse = useMouse(ref, {
    enterDelay: 100,
    leaveDelay: 100,
  })

  return (
    // You must provide the ref to the element you're tracking the
    // mouse position of
    <div ref={ref}>
      Hover me and see where I am relative to the element:
      <br />
      x: ${mouse.x}
      y: ${mouse.y}
    </div>
  )
}
