Russell Goldenberg released Scrollama.js in an effort to make scrollytelling more straightforward to implement.
Scrollytelling can be complicated to implement and difficult to make performant. The goal of this library is to provide a simple interface for creating scroll-driven interactives and improve user experience by reducing scroll jank. It offers (optional) methods to implement the common scrollytelling pattern to reduce more involved DOM calculations. For lack of a better term, I refer to it as the sticky graphic pattern, whereby the graphic scrolls into view, becomes “stuck” for a duration of steps, then exits and “unsticks” when the steps conclude.
Bookmarked for later.
