👇Bread n butter utility for component-tied mouse/touch gestures in React and Vanilla Javascript.

@use-gesture

@use-gesture is a library that lets you bind richer mouse and touch events to any component or view. With the data you receive, it becomes trivial to set up gestures, and often takes no more than a few lines of code.

You can use it stand-alone, but to make the most of it you should combine it with an animation library like react-spring, though you can most certainly use any other.

The demos are real click them!

Simple example

React

import { useSpring, animated } from '@react-spring/web'
import { useDrag } from '@use-gesture/react'

function Example() {
  const [{ x, y }, api] = useSpring(() => ({ x: 0, y: 0 }))

  // Set the drag hook and define component movement based on gesture data.
  const bind = useDrag(({ down, movement: [mx, my] }) => {
    api.start({ x: down ? mx : 0, y: down ? my : 0 })
  })

  // Bind it to a component.
  return <animated.div {...bind()} style={{ x, y, touchAction: 'none' }} />
}

Vanilla javascript

<!-- index.html -->
<div id="drag" />

// script.js
const el = document.getElementById('drag')
const gesture = new DragGesture(el, ({ active, movement: [mx, my] }) => {
  setActive(active)
  anime({
    targets: el,
    translateX: active ? mx : 0,
    translateY: active ? my : 0,
    duration: active ? 0 : 1000
  })
})

// when you want to remove the listener
gesture.destroy()

The example above makes a div draggable so that it follows your mouse on drag, and returns to its initial position on release.

Make sure you always set touchAction on a draggable element to prevent glitches with the browser native scrolling on touch devices.

Available hooks

@use-gesture/react exports several hooks that can handle different gestures:

Hook	Description
useDrag	Handles the drag gesture
useMove	Handles mouse move events
useHover	Handles mouse enter and mouse leave events
useScroll	Handles scroll events
useWheel	Handles wheel events
usePinch	Handles the pinch gesture
useGesture	Handles multiple gestures in one hook
