use-scroll-into-view 📌

useScrollIntoView is a React Hook that uses scrollIntoView to scroll a DOM Node into the view, when an extenal condition occcurs.

Installation

npm i @lucarestagno/use-scroll-into-view

Usage

import React, { useRef } from 'react'
import useScrollIntoView from 'use-scroll-into-view'

const ListItem = ({ isSelected, itemName }) => {
  const itemRef = useRef(null)
  useScrollIntoView(itemRef, isSelected)

  return (
    <li ref={itemRef}>
      {itemName}
    </li>)
}

The list item is moved into the view by automatically scrolling the container (the body or another html tag).

This is particularly useful when you have a set of elements in the page that can be outside the view, and you want to automatically move into the visible are.

The scroll works vertically and horizontally.

Typescript

The package exports the following types

type ScrollIntoViewOptions = {
  behavior?: keyof typeof ScrollIntoViewBehavior
  block?: keyof typeof ScrollIntoViewBlock
  inline?: keyof typeof ScrollIntoViewInline
}

enum ScrollIntoViewBehavior {
  auto = "auto",
  smooth = "smooth"
}

enum ScrollIntoViewBlock {
  start = "start",
  center = "center",
  end = "end",
  nearest = "nearest"
}

enum ScrollIntoViewInline {
  start = "start",
  center = "center",
  end = "end",
  nearest = "nearest"
}
