1kb minified + gzipped, no dependencies

Usage

yarn add use-drag-scroll or npm i use-drag-scroll

Basic

! The wrapping element must have overflow-x: scroll and white-space: nowrap.

Simple JSX setup:

  import React, {useRef} from 'react'
  import useDragScroll from 'use-drag-scroll'

  const Component = () => {
    const ref = useRef(null)

    useDragScroll({
      sliderRef: ref
    })

    return (
      <div className='items' ref={ref}>
        <div className='item'></div>
        <div className='item'></div>
        <div className='item'></div>
      </div>
    )
  }

Dynamic children

If the components within .items can change or be dynamically added/removed, pass reliants to useDragScroll like you would useEffect:

  import React, {useRef, useState} from 'react'
  import useDragScroll from 'use-drag-scroll'

  const Component = () => {
    const ref = useRef(null)
    const [myFilter, setMyFilter] = useState('DESC')

    useDragScroll({
      sliderRef: ref,
      reliants: [myFilter]
    })

    return (
      <div className='items' ref={ref}>
        <div className='item'></div>
        <div className='item'></div>
        <div className='item'></div>
      </div>
    )
  }

Momentum velocity

You can also alter the momentum velocity (recommended between 0.8-1.0, default 0.9):

  import React, {useRef, useState} from 'react'
  import useDragScroll from 'use-drag-scroll'

  const Component = () => {
    const ref = useRef(null)
    const [myFilter, setMyFilter] = useState('DESC')

    useDragScroll({
      sliderRef: ref,
      reliants: [myFilter],
      momentumVelocity: 0.8 
    })

    return (
      <div className='items' ref={ref}>
        <div className='item'></div>
        <div className='item'></div>
        <div className='item'></div>
      </div>
    )
  }

Arguments & Return values

Args

useDragScroll({
  sliderRef: ReactRef, // Wrapper/container ref (REQUIRED)
  reliants: [...], // Array
  momentumVelocity: Number
})

Returns

useDragScroll returns hasSwiped only. This tells you if the user has moved the mouse more than 3px horizontally. It's handy for when your items are links. You can tell links to preventDefault if the user has scrolled previously.

const { hasSwiped } = useDragScroll({
  sliderRef: ReactRef
})

return (
  <div className='items' ref={ref}>
    <a className='item' href='...' onClick={(e) => {
      if (hasSwiped) {
        e.preventDefault()
      }
    }}></a>
  </div>
)
