This component vertically scrolls a number of items within a container. Each page of items is pulled from a server which supplies JSON data. The parameters are: the data url, a css class for the container, and the time to pause between scrolling each item. Very simple! I had to do this for a project recently and couldn't find any useful "modern" implementations, so I rolled my own. The core js file is 8.5k without any compression at all, or dependencies.
