## What
Introduces the `hyperframes auth` command group + a shared credential
store library that hyperframes-CLI and heygen-cli will both read from.
- `hyperframes auth login --api-key` saves a HeyGen API key to
`~/.heygen/credentials.json` (stdin pipe or hidden-input prompt).
- `hyperframes auth status` resolves the active credential (env vars
→ file) and verifies it against `GET /v3/users/me`, printing
identity + billing.
- `hyperframes auth logout` removes the credential (`--keep-api-key`
drops only the OAuth block).
Internals (`packages/cli/src/auth/`):
- `paths.ts` — `~/.heygen` layout, `HEYGEN_CONFIG_DIR` override.
- `store.ts` — read/write `credentials.json` (file 0600, dir 0700)
with legacy single-line plaintext fallback so existing heygen-cli
users don't lose their session.
- `resolver.ts` — chain: `HEYGEN_API_KEY` → `HYPERFRAMES_API_KEY` →
file (unexpired OAuth wins over api_key).
- `client.ts` — hand-written typed wrapper for `GET /v3/users/me`
(intentionally not OpenAPI codegen — single endpoint).
- `errors.ts` — typed `AuthError` with discriminating `code`.
## Why
This is the foundation for `hyperframes cloud render`. Splitting it
out keeps the cloud-render PR small and lets users sign in today.
The plan originally called for a library-only PR followed by a
commands PR. The `fallow` dead-code gate flagged the library-only
shape as unused exports, so I bundled them — the library and its
first consumers ship together. PR 3 (OAuth PKCE) and PR 4
(heygen-cli read-side JSON support) follow.
## How
- Credential file format: JSON with optional `api_key` + `oauth`
blocks. Both CLIs read it; the resolver picks the freshest valid
credential.
- Auth header selection happens in the HTTP client: OAuth →
`Authorization: Bearer ...`, API key → `x-api-key: ...`.
- `HEYGEN_API_URL` lets dev testing target `api.dev.heygen.com`
without rebuilding.
- The new `auth` command lazy-loads its subverbs (same pattern as
`lambda`).
## Test plan
- [x] Unit tests added (`vitest`) for paths, store, resolver,
client, and errors — 45 tests, all green.
- [x] `bunx tsc --noEmit -p packages/cli/tsconfig.json` clean.
- [x] `bunx oxlint` + `bunx oxfmt --check` clean.
- [x] `bunx fallow audit --base origin/main --fail-on-issues` —
zero new findings.
- [ ] Smoke test against dev API:
`HEYGEN_API_URL=https://api.dev.heygen.com hyperframes auth login --api-key`
then `hyperframes auth status`.
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:
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.
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
