I just open-sourced 13 MIT libraries for web visual effects

After months of work, today I shipped Vysmo — a set of MIT-licensed libraries for web visual computing. All 13 packages are now on npm under @vysmo.

What's in it

@vysmo/transitions — 60 WebGL2 transition shaders defined as plain data. Includes a mesh-based page-curl with drag-scrub mid-flip, polygon flip, and classic crossfades/wipes. Tree-shakable to the byte.
@vysmo/text — Multi-property choreographed text animation with 300+ presets. Grapheme-safe splitting via Intl.Segmenter works for emoji, Arabic, and Devanagari.
@vysmo/effects — WebGL filter primitives (blur, bloom, glow, vignette, chromatic aberration, color grading).
@vysmo/easings — 40+ named curves, parametric builders (spring, bezier, wiggle, rough), composition modifiers, CSS export, reduced-motion helpers.
@vysmo/scroll — scroll-driven primitives that compose with transitions and effects.
@vysmo/flipbook — drag-scrub page-flip component built on the page-curl shader.
@vysmo/slideshow — image slideshow with opt-in chrome, drives any of the 60 transitions.
@vysmo/animations — value-based tweening: animate(), spring(), timeline(), interpolate().
@vysmo/gl-core — shared WebGL2 plumbing.
Plus React wrappers: @vysmo/transitions-react, @vysmo/text-react, @vysmo/flipbook-react, @vysmo/slideshow-react.

Design principles

Zero runtime dependencies in every package.
SSR-safe at module load — enforced by a Node import test per package.
Headless-first — components are opt-in wrappers around a vanilla TS core. The same code drives canvas, image, and video sources.
Plain-data API for transitions, text, and effects so the same definition can drive DOM today and a canvas renderer later.

Quick example

Crossfade between two images with one of the 60 WebGL transitions:

import { Runner, paintBleed } from "@vysmo/transitions";
import { animate } from "@vysmo/animations";

const canvas = document.querySelector<HTMLCanvasElement>("canvas")!;
const runner = new Runner({ canvas });

const fromImg = new Image();
const toImg = new Image();
fromImg.src = "/photo-a.jpg";
toImg.src = "/photo-b.jpg";
await Promise.all([fromImg.decode(), toImg.decode()]);

animate({
  from: 0,
  to: 1,
  duration: 1200,
  onUpdate: (p) => runner.render(paintBleed, {
    from: fromImg,
    to: toImg,
    progress: p,
  }),
});

The transition is just plain data describing how to interpolate between two textures. The Runner handles WebGL plumbing.
