`enabledAudioFxNodes()` existed and was used only by the engine, while audioFxGraph restated the same predicate three times in three shapes — `.filter((n) => n.enabled !== false)` in `shapeOf`, `if (node.enabled === false) continue` in `buildFxChain`, and the filter again in `update`. All three now call the helper. Also drops the `shape = shapeOf(next)` at the end of `update`. The early return above it already established that `shapeOf(next)` equals `shape`, so this was a full normalise-and-join of the chain per observer tick to write back the string that was already there. `shape` is `const` now, which is the compiler enforcing the same thing. Consolidating found a genuine gap: `update`'s filter had NO test. A bypassed node is not in the graph, so the update must walk the ENABLED nodes to stay aligned with what was built — walking every node shifts each one's parameters into its neighbour, and the shape is identical either way so nothing forces a rebuild that would expose it. Both other call sites failed under mutation; this one passed. Now covered, and falsified: the lowpass keeps its old cutoff while the bypassed peaking's values land on it.

@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 }[]
