Miguel Ángel 0da93cea3d feat(player): add speed control with popup menu and CSS theming (#241)
Add playback speed control to the player controls bar:
- Popup menu with logarithmic presets (0.25x-4x)
- Custom presets via speed-presets attribute
- Full CSS custom property theming (--hfp-accent, --hfp-controls-bg, etc.)
- ratechange event dispatch
- Exports: SPEED_PRESETS, formatSpeed, ControlsOptions
- Fix package.json export condition ordering

@hyperframes/player

Embeddable web component for playing HyperFrames compositions. Zero dependencies, works with any framework.

Install

npm install @hyperframes/player

Or load directly via CDN:

<script src="https://cdn.jsdelivr.net/npm/@hyperframes/player"></script>

Usage

<hyperframes-player src="./my-composition/index.html" controls></hyperframes-player>

The player loads the composition in a sandboxed iframe, auto-detects its dimensions and duration, and scales it responsively to fit the container.

With a framework

import "@hyperframes/player";

// The custom element is now registered — use it in your markup
// React: <hyperframes-player src="..." controls />
// Vue:   <hyperframes-player :src="url" controls />

Poster image

Show a static image before playback starts:

<hyperframes-player
  src="./composition/index.html"
  poster="./thumbnail.jpg"
  controls
></hyperframes-player>

Attributes

Attribute Type Default Description
src string — URL to the composition HTML file
width number 1920 Composition width in pixels (aspect ratio)
height number 1080 Composition height in pixels (aspect ratio)
controls boolean false Show play/pause, scrubber, and time display
muted boolean false Mute audio playback
poster string — Image URL shown before playback starts
playback-rate number 1 Speed multiplier (0.5 = half, 2 = double)
autoplay boolean false Start playing when ready
loop boolean false Restart when the composition ends

JavaScript API

const player = document.querySelector("hyperframes-player");

// Playback
player.play();
player.pause();
player.seek(2.5); // jump to 2.5 seconds

// Properties
player.currentTime; // number (read/write)
player.duration; // number (read-only)
player.paused; // boolean (read-only)
player.ready; // boolean (read-only)
player.playbackRate; // number (read/write)
player.muted; // boolean (read/write)
player.loop; // boolean (read/write)

Events

Event Detail Fired when
ready { duration } Composition loaded and duration determined
play — Playback started
pause — Playback paused
timeupdate { currentTime } Playback position changed (~10 fps)
ended — Reached the end (when not looping)
error { message } Composition failed to load
player.addEventListener("ready", (e) => {
  console.log(`Duration: ${e.detail.duration}s`);
});

player.addEventListener("ended", () => {
  console.log("Done!");
});

Sizing

The player fills its container and scales the composition to fit while preserving aspect ratio. Set a size on the element or its parent:

hyperframes-player {
  width: 100%;
  max-width: 800px;
  aspect-ratio: 16 / 9;
}

The width and height attributes define the composition's native resolution for aspect ratio calculation — they don't set the player's display size.

How it works

The player renders compositions in a sandboxed <iframe> inside a Shadow DOM. It communicates with the HyperFrames runtime via postMessage. If the composition has GSAP timelines (window.__timelines) but no runtime, the player auto-injects it from CDN.

Distribution

Format File Use case
ESM hyperframes-player.js Bundlers (Vite, webpack, etc.)
CJS hyperframes-player.cjs Node.js / require()
IIFE hyperframes-player.global.js <script> tag, CDN

All formats are minified with source maps. TypeScript definitions included.
