Miguel Ángel 1149602bc9 fix(studio): support web-component refs in useTimelinePlayer (#245)
* fix(studio): support web-component refs in useTimelinePlayer

The studio's `useTimelinePlayer` hook returns an `iframeRef` that
consumers attach to an `<iframe>` element. When consumers wrap the
iframe in a custom element (e.g. `<hyperframes-player>`) that puts
the iframe inside its shadow DOM, every `iframeRef.current.contentWindow`
access returned `null` and `getAdapter()` silently failed — meaning
timeline seek, play, pause, and `refreshPlayer` all became no-ops.

Changes:
- Add `resolveIframe(el)` helper that returns the underlying iframe
  whether the host is the iframe itself, a custom element with a
  shadow-DOM iframe, or a wrapper with a descendant iframe.
- Export `resolveIframe` from the studio so consumers can pre-resolve
  the iframe before assigning it to `iframeRef`.
- Internal `useTimelinePlayer` keeps the strict `HTMLIFrameElement`
  ref type, so existing consumers attaching directly to an `<iframe>`
  are unaffected.

Also adds:
- JSDoc on the player's `iframeElement` getter.
- "Advanced: iframe access" docs section in `packages/player/README.md`
  and `docs/packages/player.mdx`.
- Type-safety lint rules in `.oxlintrc.json` and a "Type-safety
  conventions" section in `CONTRIBUTING.md`.

Backward compatible — App.tsx and NLELayout.tsx continue to work
unchanged.

* chore(lint): defer no-explicit-any rule; it broke existing codebase

The new rules added 37 errors across 32 existing files — mostly
legitimate `window as any` casts at browser-global and test-mock
boundaries. Enabling them without fixing all violations breaks CI.

Revert the `.oxlintrc.json` additions and soften the CONTRIBUTING.md
wording to describe the convention without claiming lint enforcement
(that enforcement will come in a follow-up PR that fixes all sites).

Hyperframes

npm version License Node.js

Write HTML. Render video. Built for agents.

Hyperframes is an open-source video rendering framework that lets you create, preview, and render HTML-based video compositions — with first-class support for AI agents via MCP.

Why Hyperframes?

  • HTML-native — AI agents already speak HTML. No React required.
  • Frame Adapter pattern — bring your own animation runtime (GSAP, Lottie, CSS, Three.js).
  • Deterministic rendering — same input = identical output. Built for automated pipelines.
  • AI-first design — not a bolted-on afterthought.

Quick Start

npx hyperframes init my-video
cd my-video

Then open the project with your AI coding agent (Claude Code, Cursor, etc.) — it has HyperFrames skills installed and knows how to create and edit compositions.

npx hyperframes preview      # preview in browser (live reload)
npx hyperframes render   # render to MP4

Requirements: Node.js >= 22, FFmpeg

How It Works

Define your video as HTML with data attributes:

<div id="stage" data-composition-id="my-video" data-start="0" data-width="1920" data-height="1080">
  <video
    id="clip-1"
    data-start="0"
    data-duration="5"
    data-track="0"
    src="intro.mp4"
    muted
    playsinline
  ></video>
  <img id="overlay" data-start="2" data-duration="3" data-track="1" src="logo.png" />
  <audio
    id="bg-music"
    data-start="0"
    data-duration="9"
    data-track="2"
    data-volume="0.5"
    src="music.wav"
  ></audio>
</div>

Preview instantly in the browser. Render to MP4 locally. Let AI agents compose videos using tools they already understand.

Packages

Package Description
hyperframes CLI — create, preview, lint, and render compositions
@hyperframes/core Types, parsers, generators, linter, runtime, frame adapters
@hyperframes/engine Seekable page-to-video capture engine (Puppeteer + FFmpeg)
@hyperframes/producer Full rendering pipeline (capture + encode + audio mix)
@hyperframes/studio Browser-based composition editor UI

AI Agent Skills

HyperFrames ships skills that teach AI coding agents (Claude Code, Gemini CLI, Codex, Cursor) how to write correct compositions and GSAP animations. Use these instead of writing from scratch — they encode framework-specific patterns that generic docs don't cover.

# Install all skills (HyperFrames + GSAP) — runs automatically during `hyperframes init`
npx hyperframes skills

# Or install to a specific agent
npx hyperframes skills --claude
npx hyperframes skills --cursor

Or via npx skills add

# HyperFrames skills (hyperframes-compose, hyperframes-captions)
npx skills add heygen-com/hyperframes

# GSAP skills (gsap-core, gsap-timeline, gsap-scrolltrigger, gsap-plugins, gsap-performance, gsap-utils, gsap-react, gsap-frameworks)
npx skills add greensock/gsap-skills
