Smoke-and-mirrors

Smoke-and-mirrors is an ember-addon that focuses on improving initial and re-render performance in high-stress situations by providing components and primitives for performant lists and svelte renders to match a core belief: Don't render the universe, render the scene.

TL;DR svelte render: the fewer things you need to render, the faster your renders will be.

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 let's 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.

Smoke-and-mirrors augments your existing app, it doesn't ask you to rewrite layouts or logic in order to use it. It will try it's best to allow you to keep the conventions, structures, and layouts you want.

Features

Infinite Scroll (bi-directional)

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.

Horizontal Scrolling

All of the above demos work horizontally as well via the horizontal-collection.

Grid Scrolling

All of the above demos (both horizontal and vertical) work as well via

grid-collection
horizontal-grid
vertical-grid

Svelte Anything

Under the hood, smoke-and-mirrors is using a powerful scroll-tracking abstraction for each of the components above. That abstraction is made available as a service.

Dependencies

smoke-and-mirrors is dependent on and installs ember-run-raf, which helps you budget and schedule the work in your app more intelligently.
