Window Scroll

Track and manipulate the scroll position of a web page

About

The useWindowScroll hook tracks and manipulates the scroll position of a webpage within a React component. It provides access to the current scroll coordinates (x and y) through the “state” object and a “scrollTo” function to programmatically scroll to a specific position on the page. This hook is useful for dynamic behavior based on the scroll position, such as lazy-loading content, infinite scrolling, or implementing smooth scrolling animations.

Return Values

NameTypeDescription
stateobjectAn object representing the current window scroll position.
scrollTofunctionA function that can be used to scroll the window to a specific position.

Installation

npx scriptkavi-hooks@latest add window-scroll
