Miguel Angel Simon Sierra 1cb59c1fd2 fix(studio-server): invalidate the memoized signature after minting hf-ids
Re-resolving the project signature after persistHfIdsIfNeeded was a no-op:
both adapters memoize the signature and invalidate it from a file watcher,
which has not fired for a write the server itself just made. The re-resolve
returned the pre-stamp value, so the first request for a project served an
ETag the second request already disagreed with, and rebuilt.

Verified end to end: minting request now serves the post-stamp ETag and the
next request gets 304, where before it got 200.

hyperframes

CLI for creating, previewing, and rendering HTML video compositions.

Install

npm install -g hyperframes

Or use directly with npx:

npx hyperframes <command>

Requirements: Node.js >= 22, FFmpeg

Commands

init

Scaffold a new Hyperframes project from a template:

npx hyperframes init my-video
cd my-video

preview

Start the live preview studio in your browser:

npx hyperframes preview
# Studio running at http://localhost:3002

npx hyperframes preview --port 4567

render

Render a composition to MP4. Run from the project directory; the positional argument is the project directory (not a file), so render the project's index.html directly, or point at a specific composition file with -c:

npx hyperframes render -o output.mp4
npx hyperframes render -c ./my-composition.html -o output.mp4

lint

Validate your Hyperframes HTML:

npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json      # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose   # Include info-level findings

By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.

compositions

List compositions found in the current project:

npx hyperframes compositions

benchmark

Run rendering benchmarks:

npx hyperframes benchmark ./my-composition.html

doctor

Check your environment for required dependencies (Chrome, FFmpeg, Node.js):

npx hyperframes doctor

browser

Manage the bundled Chrome/Chromium installation:

npx hyperframes browser
