Jump.js is a modern smooth scrolling library for JavaScript.
The library solves the problem of implementing smooth scroll animations to specific positions or elements on a page. It works by exporting a singleton function that accepts a target—either a pixel offset, a DOM node, or a CSS selector—and animates the scroll to that location using requestAnimationFrame. The animation respects configurable options including duration, easing functions, pixel offsets for fixed headers, completion callbacks, and accessibility features.
Jump.js suits projects that need straightforward smooth scrolling without heavy dependencies. It works well for single-page applications, documentation sites, and any interface requiring animated navigation to page sections. The library is designed for modern JavaScript workflows with ES6 transpilation and module bundling. Developers should be aware that the accessibility option is disabled by default because focusing elements triggers browser focus styling, which may have visual implications depending on the site's CSS.
The project maintains a focused scope with no plans to include polyfills for older browser support, prioritizing a small file size instead. Development activity shows consistent attention to the codebase with regular updates addressing issues and maintaining compatibility with modern JavaScript practices.
