- play.ts: move --remote-debugging-port parse+deps validation before any server setup so an invalid value exits cleanly instead of leaking a listening socket (the original bug — server printed 'Player running' and 'Press Ctrl+C to stop' before failing). - Extract validateRemoteDebuggingPortDeps() in openBrowser.ts to keep preview.ts and play.ts in sync instead of copy-pasting the dep checks. - Narrow parseRemoteDebuggingPort param to string | undefined; drop the dead null branch and the redundant String() / Number.isInteger() now that the regex already constrains the input. - buildBrowserArgs: omit --remote-debugging-port when userDataDir is missing so a CDP endpoint cannot leak into the user's main profile even if a caller bypasses the CLI validation layer. - Replace the duplicated buildBrowserArgs case with one that proves this defense-in-depth behaviour; add unit tests for validateRemoteDebuggingPortDeps. - Drop the heavy JSDoc on parseRemoteDebuggingPort to match the file's surrounding style. - Both commands: align --remote-debugging-port description (it now matches the actual 'requires --browser-path and --user-data-dir' contract) and add a CDP example to the --help output.
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

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.
