Scrollio is a slim yet extensible smooth scrolling solution.

It aims to solve one thing, and one thing only:

creating a jank-free smooth scroll which can be controlled by either one of the provided easing functions, or by a user-provided one.

Why is it headless?

Scrollio exposes its entire internal API to be used in your own project. It comes with a usable example function in order to provide a possible solution, yet the use of it is not mandatory.

Getting Started

# Get scrollio from npm
npm i scrollio-js

# Import either Scrollio or one of its subset functions
import {Scrollio} from "scrollio-js";

# Get started with an example configuration

const scrollio = new Scrollio({
  scrollElement: elementRef,
  duration: 800,
  easingFunction: "easeInOutQuad"
});

# Scroll somewhere!
scrollio.scrollTo(250);

Big thanks for yukulele and gre whose gists inspired parts of this solution.

TODOS

• Demos: Comming soon! I promise()!
• Support x position scrolling (breaking change)
• Add an onScroll event (currently polyfillable with scrollElement.addEventListener("scroll", () => {...})), consider using ReadableStream (similar to the fetch API)
• Add testing
