canvas.drawElementImage is an unlaunched Dev/Canary-only Blink feature
(~151+). The CLI's pinned CHROME_VERSION fallback was still 131.0.6778.85 —
a puppeteer 24→25.2.1 bump that pinned it to Chrome Dev 151.0.7912.0 was
written on 2026-06-29 but never merged (orphaned local commit, no PR). Any
render on that pin, or on the shared puppeteer-cache binary, or on system
Chrome (Stable, no drawElementImage at all) got a canvas.getContext("2d")
missing the method and crashed mid-capture with "ctx.drawElementImage is
not a function" instead of falling back (HF#2060).
Three changes:
- Bump puppeteer/puppeteer-core to ^25.2.1 across every package that
depends on it, and CHROME_VERSION to 152.0.7928.2 (today's Dev channel;
confirmed via direct probe to implement drawElementImage, unlike 131).
- `ensureBrowser({ preferManagedChrome: true })`, always used by `render`:
resolve straight to our pinned/cached build, skipping both the shared
puppeteer-cache preference and system Chrome. Rendering shouldn't depend
on whatever arbitrary Chrome a machine happens to have — that's exactly
how this regressed (any Mac with Chrome.app installed bypassed the CLI's
pin entirely).
- A runtime capability probe in the engine, right before any other
drawElement work: if `drawElementImage` isn't a function on the injected
canvas, route to the existing screenshot-fallback gate instead of
crashing. This is the real backstop — it protects every resolution path
(env override, stale cache entry, a future Chrome regression), not just
the ones `preferManagedChrome` reaches.
Verified end-to-end: rendering against chrome-headless-shell 131 (confirmed
to lack drawElementImage) now falls back cleanly and produces a valid MP4
instead of crashing; rendering against a capable build still engages
drawElement normally. 922 engine tests + 1373 CLI tests pass.
Fixes #2060.
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
info
Print version and environment info:
npx hyperframes info
docs
Open the documentation in your browser:
npx hyperframes docs
upgrade
Check for updates and show upgrade instructions:
npx hyperframes upgrade
npx hyperframes upgrade --check --json # machine-readable for agents
