doctor, browser

Environment diagnosis and bundled-Chrome management. Run these first when a render or preview fails.

doctor

npx hyperframes doctor
npx hyperframes doctor --json     # CI / agent output (always exit 0; gate on payload `ok`)

Runs independent checks and reports each as ok/warn/fail:

  • Version — installed CLI vs latest on npm (hints upgrade when stale)
  • Node.js — ≥ 22 required
  • CPU, Memory, Disk — host resources
  • Environment — env vars that affect the renderer
  • FFmpeg / FFprobe — found, version, codecs
  • Chrome — bundled or system, version, path
  • Docker / Docker running — required only for render --docker
  • /dev/shm — inside containers only

Run doctor first when:

  • render fails with a Chrome or FFmpeg error.
  • preview opens but the composition fails to load.
  • A fresh machine has never run HyperFrames.

Common issues:

  • Missing FFmpeg — install via brew install ffmpeg (macOS) or your package manager.
  • Missing bundled Chrome — run npx hyperframes browser ensure.
  • Low memory — close other Chromes, reduce --workers, or use --quality draft.

browser

npx hyperframes browser ensure    # find or download the pinned Chrome
npx hyperframes browser path      # print the browser executable path (for scripting)
npx hyperframes browser clear     # remove the cached Chrome download

Manage the Chrome build HyperFrames uses for rendering. The pinned version exists because pixel output drifts across Chrome versions — using the bundled build keeps rendered output reproducible across machines.

Use path to embed the binary in scripts: $(npx hyperframes browser path).
