Infinite Scroll and Occlusion at > 60FPS
vertical-collection
is an ember-addon
that is part of the smoke-and-mirrors
framework. It
focuses on improving initial and re-render performance in high-stress situations by providing a
component for performant lists and svelte renders
to match a core belief:
Don't render the universe, render the scene.
Your web page is a universe, your viewport is the scene. Much like you wouldn't expect a video game to render out-of-scene content, your application should smartly cull the content it doesn't need to care about. Trimming excess content lets the browser perform both initial renders and re-renders at far higher frame-rates, as the only content it needs to focus on for layout is the content the user can see.
vertical-collection
augments your existing app, it doesn't ask you to rewrite layouts or logic in order to use it.
It will try its best to allow you to keep the conventions, structures, and layouts you want.

Infinite scroll that remains performant even for very long lists is easily achievable
with the vertical-collection
.
It works via a scrollable div or scrollable body.
If it can be trimmer, smoke-and-mirrors likes to trim it.
