Miguel ÁngelandClaude Opus 4.6 08c6bb84fe fix(lint): address review — companion rule, style blocks, axis fix
- Add `composition_root_missing_container_type` rule (warning) that
  fires when cqw/cqh units are used without container-type:size on root
- Scan `<style>` blocks via postcss, not just inline styles
- Use explicit property set instead of regex — fixes axis confusion for
  padding-top/margin-bottom etc, drops border-radius from flagged props
- Guard on data-composition-id presence, not just rootTag existence
- Handle malformed data-width/data-height with isFinite guard
- 17 tests (12 for prefer_container_units, 5 for missing container-type)

@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 }[]
