Zynga Scroller

Scroller, also known as Zynga Scroller, is a pure JavaScript logic component for accelerated scrolling and zooming. It is independent of any rendering layer, which means it can power interactions for DOM elements, Canvas interfaces, or other custom rendering systems. The library handles panning, deceleration, bouncing, paging, snapping, zooming, directional locking, and pull-to-refresh behavior. It can be controlled manually through an API or used through EasyScroller, a simplified DOM-focused wrapper with data-attribute initialization. Developers can configure axes, animation behavior, zoom ranges, dimensions, and scroll targets. It is useful for web applications, games, visual tools, and custom interfaces that need smooth touch or mouse-driven navigation without relying entirely on native browser scrolling.
