Miguel Ángel 92f3116dee fix(cli): re-download the browser when the cached archive is corrupt
A partially-downloaded or interrupted chrome-headless-shell archive left in the
cache makes @puppeteer/browsers' install() throw "invalid
end-of-central-directory" during extraction. That error propagated out of the
browser check and hard-blocked the render, forcing users onto the fallback
renderer until they manually cleared the cache — a recurring Windows failure.

Detect the corrupt-archive extraction error (isCorruptArchiveError), clear the
cache to drop the bad archive, and retry the download exactly once; non-corrupt
errors and a second corruption still propagate (no infinite retry). The pure
predicate and the recovery wrapper are unit-tested.

hyperframes

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

npm install -g hyperframes

Or use directly with npx:

npx hyperframes <command>

Commands

init

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:

npx hyperframes render ./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.
