nodeToHtml routed rasterize eligibility off node.type alone, so a RECTANGLE/FRAME with an IMAGE fill fell through to the generic <div> path — fillCss() has no IMAGE case, so it rendered an empty box. IMAGE-filled nodes now route to rasterize like vectors, regardless of node.type. Rasterized nodes (vectors, now image fills too) were also getting their own fill/corner-radius CSS applied on top of the already- rendered <img> — a flat color block behind/around the real art, flattening non-rectangular shapes into rounded rects. decorationCss now skips background and corner-radius/clip for rasterized nodes; opacity and effects still apply since those aren't baked into the export. tokens.ts's styles-fallback path hardcoded entries: [] regardless of how many published styles were actually found, so the CLI printed "recorded published style metadata instead" even when styles() returned zero results. Added styleCount to the result so the message reflects what happened, and points at the MCP get_variable_defs fallback when there's nothing to fall back to.

@hyperframes/core
Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.
Install
npm install @hyperframes/core
Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.
What's inside
| Module | Description |
|---|---|
| Types | TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults |
| Parsers | parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations |
| Generators | generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec |
| Compiler | compileTimingAttrs — resolve data-start / data-duration into absolute times |
| Linter | lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.) |
| Runtime | IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol |
| Frame Adapters | Pluggable animation drivers (GSAP, Lottie, CSS, or custom) |
Frame Adapters
A frame adapter tells the engine how to seek your animation to a specific frame:
import { createGSAPFrameAdapter } from "@hyperframes/core";
const adapter = createGSAPFrameAdapter({
getTimeline: () => gsap.timeline(),
compositionId: "my-video",
});
Implement FrameAdapter for custom animation runtimes:
import type { FrameAdapter } from "@hyperframes/core";
const myAdapter: FrameAdapter = {
id: "my-adapter",
getDurationFrames: () => 300,
seekFrame: (frame) => {
/* seek your animation */
},
};
Parsing and generating HTML
import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";
const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);
Linting
import { lintHyperframeHtml } from "@hyperframes/core/lint";
const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
