Opens N browser tabs (via window.open with noopener) for true multi-process parallelism. Each tab gets its own Chromium renderer process with independent main thread, bypassing the single-thread SnapDOM bottleneck. Architecture: - TurboPool coordinator opens N minimized offscreen tabs - Each tab loads composition via SnapdomFrameSource independently - Frames captured as PNG, sent via BroadcastChannel to coordinator - Coordinator decodes to ImageBitmap, feeds reorder buffer + encoder - Concurrency: min(cores/2, 6), capped at 6 tabs - Falls back to normal IframePool if popups blocked Also: - Add turbo toggle (lightning bolt) to Studio render UI - Add /api/projects/:id/renders/upload endpoint for saving browser-rendered videos to project renders directory - Export isTurboSupported() from @hyperframes/renderer Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
@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 }[]
