Scroll Direction

This library is my approach to gracefully detecting vertical scroll direction in a browser. It works by keeping track of a series of throttled detect events, then invoking a callback with a direction argument once the series contains only one event direction.

Usage

var s = new ScrollDirection(function (dir) {
  console.log(dir)
})

Options

There are two options, series and throttle. Tweak the options to get the desired behavior.

var options = {
  series: 5,
  throttle: 100
}
new ScrollDirection(callback,options)

Destroy

s.destroy()

Installation

As a library consumed and packaged by something like Webpack or Rollup.

npm install @ryanburnette/scroll-direction

var ScrollDirection = require('@ryanburnette/scroll-direction')
