HyperFrames Registry

The registry provides reusable blocks and components installable via hyperframes add <name>.

• Blocks — standalone sub-compositions (own dimensions, duration, timeline). Included via data-composition-src in a host composition.
• Components — effect snippets (no own dimensions). Pasted directly into a host composition's HTML.

Quick reference

hyperframes add data-chart              # install a block
hyperframes add grain-overlay           # install a component
hyperframes add captions                # install every block tagged captions
hyperframes add shimmer-sweep --dir .   # target a specific project
hyperframes add data-chart --json       # machine-readable output
hyperframes add data-chart --no-clipboard  # skip clipboard (CI/headless)

After install, the CLI prints which files were written and a snippet to paste into your host composition. The snippet is a starting point — you'll need to add data-composition-id (must match the block's internal composition ID), data-start, and data-track-index attributes when wiring blocks.

The positional value is resolved as an exact item name first. If no item matches and the value is a tag, the command installs every block with that tag. Registry dependencies are installed before the requested item. hyperframes add works only for blocks and components; for examples, use hyperframes init <dir> --example <name> instead.

Install locations

Blocks install to compositions/<name>.html by default. Components install to compositions/components/<name>.html by default.

These paths are configurable in hyperframes.json:

{
  "registry": "https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry",
  "paths": {
    "blocks": "compositions",
    "components": "compositions/components",
    "assets": "assets"
  }
}

See install-locations.md for full details.

Wiring blocks

Blocks are standalone compositions — include them via data-composition-src in your host index.html:

<div
  data-composition-id="data-chart"
  data-composition-src="compositions/data-chart.html"
  data-start="2"
  data-duration="15"
  data-track-index="1"
  data-width="1920"
  data-height="1080"
></div>

Key attributes:

• data-composition-src — path to the block HTML file
• data-composition-id — must match the block's internal ID
• data-start — when the block appears in the host timeline (seconds)
• data-duration — how long the block plays
• data-width / data-height — block canvas dimensions
• data-track-index — layer ordering (higher = in front)

See wiring-blocks.md for full details.

Wiring components

Components are snippets — paste their HTML into your composition's markup, their CSS into your style block, and their JS into your script (if any):

1. Read the installed file (e.g., compositions/components/grain-overlay.html)
2. Copy the HTML elements into your composition's <div data-composition-id="...">
3. Copy the <style> block into your composition's styles
4. Copy any <script> content into your composition's script (before your timeline code)
5. If the component exposes GSAP timeline integration (see the comment block in the snippet), add those calls to your timeline

See wiring-components.md for full details.

Discovery

Use the CLI as the primary discovery surface:

npx hyperframes catalog
npx hyperframes catalog --type block
npx hyperframes catalog --type component
npx hyperframes catalog --type block --tag social
npx hyperframes catalog --json
npx hyperframes catalog --human-friendly

The normal table and --json modes only list matches; install a selected name with hyperframes add <name>. --human-friendly opens an interactive picker and installs the selected item immediately. In CI or agent workflows, prefer --json followed by an explicit add.

If the CLI cannot reach the configured registry, inspect the raw manifest as a fallback:

curl -s https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry/registry.json

Each item's registry-item.json contains: name, type, title, description, tags, dimensions (blocks only), duration (blocks only), and file list.

See discovery.md for details on filtering by type and tags.

Contributing a new block or component

To author a NEW registry item (caption style, VFX block, transition, lower third, or a reusable component) and ship it as an upstream PR — not install an existing one — follow the full idea → scaffold → build → validate → preview → ship workflow in contributing.md. Copy-paste starter templates (caption / VFX / component / registry-item.json) are in templates.md.
