Closes #3370 ## What When `hyperframeRuntimeLoader` could not locate `hyperframe.manifest.json`, the loader reported a single fallback path that was never searched for (`/usr/local/lib/core/dist/hyperframe.manifest.json`). Inside a Docker render the user is then told to look at the wrong directory; the file that was actually missing (`/usr/local/lib/node_modules/hyperframes/dist/hyperframe.manifest.json`) was nowhere in the message. ## Why `resolveHyperframeManifestPath()` built a 5-element `candidates` array, walked it with `existsSync`, and on total miss returned the last candidate. The error then quoted that candidate verbatim. The reporter even shows the exact reproducing command from a published image. A second issue rode the same failure path: `packages/cli/src/commands/render.ts:902` keeps attaching the hint `"Try --docker for containerized rendering"` to users who are *already inside* the container. The container sets `ENV CONTAINER=true` and nothing reads it. A third small thing came along: `CWD_RELATIVE_MANIFEST_PATHS[0]` was a byte-identical duplicate of `SIBLING_MANIFEST_PATH` — same path, two names. ## How 1. Hoist the candidate list to a single `MANIFEST_CANDIDATES` owner in `hyperframeRuntimeLoader.ts` and share it between the resolver and the error reporter. De-duplicate while doing it. 2. Add `triedManifestPaths()` as a tiny export so callers (and tests) can see what was actually searched. 3. Replace the source-text regex test that asserted on string positions inside `const candidates = [...]` with a behaviour test that points `PRODUCER_HYPERFRAME_MANIFEST_PATH` at a missing file and asserts the thrown error names it. Also exercise the no-override branch to confirm the sibling path is the first entry. 4. In `render.ts`, check `process.env.CONTAINER === "true"` before attaching the `--docker` hint. The chrome-launch and macos-old-chrome remediation branches already short-circuit before the hint, so an empty string is a safe value when the user is in the container. ## Test plan - [x] `bunx vitest run src/services/hyperframeRuntimeLoader.test.ts` — 7/7 pass (`hyperframeRuntimeLoader error path (#3370)` describe covers the missing-manifest message and the tried-paths export). - [x] `bunx tsc --noEmit` in `packages/producer` and `packages/cli` — clean. - [x] `bunx oxfmt --check` and `bunx oxlint` on the touched files — clean. - [x] `bunx fallow audit --base origin/main` — no new findings on the touched files. - [x] Targeted producer unit lane: `node scripts/run-test-lane.mjs unit` — same 7 pre-existing failures as `origin/main` before the change (htmlCompiler.parity, audioPadTrim.integration); no regressions introduced. Files touched: - `packages/producer/src/services/hyperframeRuntimeLoader.ts` - `packages/producer/src/services/hyperframeRuntimeLoader.test.ts` - `packages/cli/src/commands/render.ts`
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: http://localhost:3002/#project/my-video
# Server: http://localhost:3002
npx hyperframes preview --port 4567
In an interactive terminal, the preview stays attached until you press
Ctrl+C. In a non-interactive shell such as a coding-agent session, the same
command starts a managed preview that survives after the command returns. Use
--background or --foreground to choose explicitly, and manage persistent
previews with --status, --stop, --list, and --kill-all. Add --json to
managed lifecycle commands for machine-readable output. --foreground --json
prints the ready-session envelope once, then remains attached until stopped.
normalize-audio
Measure two local authored audio clips with integrated LUFS and match the target
to the unchanged reference. The command is a dry run unless --write is passed:
npx hyperframes normalize-audio --reference target-audio --target user-audio
npx hyperframes normalize-audio --reference target-audio --target user-audio --write
It updates only the target element's data-volume and refuses unsafe boosts
that exceed Studio's +12 dB ceiling or would clip.
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
