It's streamlined for the specific use case of rendering 2D graphics using fragment shaders as an alternative to SVG or the JS canvas API, so it's not meant for doing 3D objects like three.js, for example.

This started as something I needed for my own project, but I eventually decided to split it into a separate library. I've since found that this use case fits really well into the Svelte compiler-based approach and its fine-grained reactivity system.

In general, I think using shaders like these has some really positive upsides compared to traditional ways of doing graphics on the web — not just for games and stuff, but also for something like data visualizations and aesthetic details. My dream is that one day, you'll see web developers using small, isolated shader components ubiquitously across web applications, just as naturally as something like SVGs are used today.
