Addresses review feedback from Rames and Vai: 1. Add 7 new tests for createStudioPositionSeekReapplyScript: box-size reapplication, GSAP translate stripping (identity removal, scale+translate preservation, transform:none no-op), and rotation- only elements with GSAP-baked translate. 2. Add pinning test for the PiP-over-sub-composition selection bug: elementsFromPoint returns [pipVideo, subCompRoot, sfChromeImg] as siblings — assert the topmost (pipVideo) wins. 3. Apply stripGsapTranslateFromTransform to rotation-only elements too, not just path-offset elements. A rotation-only element with a GSAP-animated translate would have its position clobbered. 4. Remove dead exports: getPreviewLocalPointer, buildRasterClickSelectionContext, getPreviewPlayer, seekStudioPreview, PreviewPlayerCompat, PreviewLocalPointer from studioPreviewHelpers.ts. Unexport resolvePreviewLocalPointer.
@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 }[]
