Demo

Overview

This package includes two hooks for scrolling the page to any coordinates, or by any amount. They both use the the Window Web API's scroll functions and support using ScrollToOptions for smooth scrolling implemented natively by the browser.

  • useScrollBy - Returns a function to scroll the page up or down by any amount, in pixels. Supports smooth scrolling.
  • useScrollTo - Returns a function to scroll the page to any page coordinates, in pixels. Supports smooth scrolling.

Click either of those to see a live demo (at bottom of page).

Features include:

  • 🎯 Scroll the page to any pixel coordinates, or by any pixel amount
    • Easily send your viewer to any location on the page. Great for scrolling to the top on first render, or smoothly sending to the top when reaching the bottom.
  • 😎 Native smooth scrolling support
  • 🧮 Legacy browser support
    • Includes polyfill to support browsers that lack native smooth scrolling support (I'm looking at you, Safari!)
  • 🤏 Low overhead
  • 🛡️ Safely access the Window Web API
    • Accessing window haphazardly in React is considered sloppy. These hooks follow the React paradigm of containing side-effects.
