:surfer: S

S is a JavaScript library that allows you to implement custom scroll events.This is a fork of Bartek Drozdz VirtualScroll util and weighs ~1.5KB (minified and compressed).

:tada: Goals of the fork

• Easier to add in a CommonJS environment
• Enable to create several distinct instances by using a prototype rather than a singleton

Installation

npm install @mystroken/s

Usage & API

• new S(options) Return a new instance of S. See the options below.

• instance.on(fn) Listen to the scroll event using the specified function (fn).

• instance.off(fn) Remove the listener.

• instance.destroy() Will remove all events and unbind the DOM listeners.

Options

• el: the target element for mobile touch events. Defaults to window.
• mouseMultiplier: General multiplier for all mousewheel (including Firefox). Default to 1.
• touchMultiplier: Mutiply the touch action by this modifier to make scroll faster than finger movement. Defaults to 2.
• firefoxMultiplier: Firefox on Windows needs a boost, since scrolling is very slow. Defaults to 15.
• keyStep: How many pixels to move with each key press. Defaults to 120.
• preventTouch: If true, automatically call e.preventDefault on touchMove. Defaults to false.
