Guard buildHyperframesRuntimeScript() against missing entry.ts so it
returns null instead of crashing with esbuild stderr output. Add
getHyperframeRuntimeScript() that returns the pre-built IIFE as a
baked-in string constant — no esbuild, no file I/O, no import.meta.url.
Consolidate CLI runtime source resolution into a single module with
a clear priority chain: esbuild from source (dev) → inlined constant
(production) → pre-built artifact file (fallback).
Add CI smoke test that npm-packs the CLI, installs globally, runs
hyperframes preview, and asserts no stderr errors + runtime endpoint
returns JS.
Bump version to 0.4.16.
## Summary
Coordinated minor bump across all published packages. No source changes in this PR itself; it is the version stamp for everything that landed on main since v0.2.5.
## Version bumps
| Package | from | to |
|---|---|---|
| `@hyperframes/cli` | 0.2.5 | **0.3.0** |
| `@hyperframes/core` | 0.2.5 | **0.3.0** |
| `@hyperframes/engine` | 0.2.5 | **0.3.0** |
| `@hyperframes/player` | 0.2.7 | **0.3.0** |
| `@hyperframes/producer` | 0.2.5 | **0.3.0** |
| `@hyperframes/studio` | 0.2.9 | **0.3.0** |
Between 0.2.5 and this release, `player` and `studio` received several patch versions on npm as we iterated on the bundler, entry point, and SSR issues. 0.3.0 collapses that into a single coordinated minor so the ecosystem is aligned again.
## What is in v0.3.0
### `@hyperframes/player`
**Restored package entry points to the compiled `dist/` output.** 0.2.5 shipped with `"main": "./src/hyperframes-player.ts"` but the published tarball only included `dist/` via the `"files"` field. Every consumer trying to import the package failed with `Module not found: Can't resolve '@hyperframes/player'`. Entry points now point at the built JS/`.d.ts` files inside `dist/`.
**DOM-based root timeline resolution in the ready probe.** In a bundled preview, `window.__timelines` contains the master composition alongside its sub-compositions, for example:
```js
{
main: GSAPTimeline(14s),
intro: GSAPTimeline(1.5s),
'scene2-4-canvas': GSAPTimeline(12.6s),
'scene5-logo-outro': GSAPTimeline(3.2s),
}
```
The probe used to select the adapter with `keys[keys.length - 1]`. Object key ordering meant the last-registered sub-composition would win, so the `ready` event reported a sub-composition's duration (e.g. 3.2s) instead of the master's 14s. The probe now looks up the root composition id from the outermost `[data-composition-id]` element in the iframe DOM and uses its key. Falls back to the last key when no element is present, so standalone sub-composition previews keep working.
### `@hyperframes/studio`
**`useTimelinePlayer.getAdapter()` uses the same DOM-based root id lookup** as the player. Previously play, pause, seek, and duration readout were all driven by whichever sub-composition happened to register its timeline last.
**`Player.tsx` loads `@hyperframes/player` lazily.** The component used to call `import "@hyperframes/player"` at module scope, which runs the package's `customElements.define(...)` side effect during module evaluation. `HTMLElement` does not exist in the Node runtime, so any consumer page that transitively imported the studio during server rendering threw:
```
ReferenceError: HTMLElement is not defined
at module evaluation (@hyperframes/studio/src/player/components/Player.tsx)
```
The import now runs inside the mount effect via `import(...)` so it only evaluates in the browser. Added a cancellation flag and deferred cleanup so a fast unmount before the dynamic import resolves does not leak listeners or DOM nodes.
**Captions module imports stripped of `.js` extensions.** Files under `src/captions/` imported siblings as `./types.js` and `./parser.js`. That is legal ESM TypeScript but Turbopack and several other bundlers refuse to resolve those specifiers against `.ts` files inside `node_modules`, breaking any consumer build that transitively pulled in the captions module. Captions now uses extensionless imports, matching the rest of the studio codebase.
### `@hyperframes/core`, `@hyperframes/cli`, `@hyperframes/engine`, `@hyperframes/producer`
Version bump only, no source changes since 0.2.5. Kept on the same version so the ecosystem is easier to reason about.
## Impact for consumers
If you use `@hyperframes/studio` in a Next.js app:
- The play button in a bundled preview reports the correct composition duration and drives the master timeline.
- The session page no longer 500s in dev mode when the studio barrel is imported (the SSR fix).
- Turbopack builds that transitively load the captions module no longer fail on `Cannot resolve './types.js'`.
If you use `@hyperframes/player` directly:
- Consumer bundlers can resolve the package again (dist entry points restored).
- The `ready` event duration reports the master, not a sub-composition.
## After merge
Publish each package to npm with `pnpm publish` (workspace deps auto-resolve).
* fix(studio): load @hyperframes/player lazily to support SSR
Player.tsx had a bare `import "@hyperframes/player"` at module scope. The
player package registers a class that extends HTMLElement as a side effect,
and HTMLElement doesn't exist in a Node server runtime. Any consumer that
imported from @hyperframes/studio during server-side rendering (e.g. the
Next.js App Router evaluating a client component for SSR) threw
`HTMLElement is not defined`.
Move the import inside the mount effect via dynamic `import(...)` so it
only runs in the browser, and wire up a cancellation flag and deferred
cleanup so a fast unmount doesn't leak listeners or DOM nodes.
* fix(studio): remove .js extensions from captions-internal imports
The captions module imported sibling files as `./types.js` and
`./parser.js`. That's legal ESM TypeScript, but Turbopack (and other
bundlers) refuse to resolve those specifiers against .ts files when the
package is consumed from node_modules — the rest of @hyperframes/studio
uses extensionless imports for that reason.
Align captions with the rest of the codebase so the package builds
without bundler-specific configuration in consumers.
* chore: release @hyperframes/player@0.2.7 and @hyperframes/studio@0.2.9
Ships the root-timeline resolution fix (#247), the SSR-safe player load,
and the captions import cleanup.
## Summary
- **Replaces the studio's hand-rolled iframe + scaling in** **`Player.tsx`** with the `<hyperframes-player>` web component, eliminating duplicated ResizeObserver, dimension detection, and stage-size message handling
- **Adds a public** **`iframeElement`** **getter** to the player web component so the studio's `useTimelinePlayer` can still access the inner iframe for clip manifest parsing, timeline probing, and DOM inspection
- **Updates player package exports** to resolve from source for workspace consumers (matching `@hyperframes/core` pattern), while npm-published consumers still get built `dist/` files
### Why a separate player package?
1. **Zero dependencies, any framework** — 12KB vanilla web component vs 940KB React+Zustand+CodeMirror studio
2. **CDN-ready** — single `<script>` tag, no build pipeline needed
3. **Embeddable by third parties** — users embed compositions in their own sites without the studio
4. **Single source of truth** — studio now uses the player instead of duplicating its scaling/detection logic
## Test plan
- [x] `pnpm --filter @hyperframes/player typecheck` passes
- [x] `pnpm --filter @hyperframes/studio typecheck` passes
- [x] `pnpm --filter @hyperframes/studio build` passes
- [x] `pnpm --filter @hyperframes/studio test` passes (2 pre-existing failures, unrelated)
- [x] E2E: Standalone player loads composition, detects 4s GSAP timeline, controls work, play/pause works
- [x] E2E: Studio preview renders via `<hyperframes-player>`, `iframeElement` bridge works, playback controls sync correctly
## Summary
- The Vite dev server proxied studio renders to a separate producer server (port 9847) that needed to be started manually
- When the producer wasn't running, renders silently failed — red dot, no error message, no way to know what went wrong
- Replaced the proxy with direct in-process rendering via `@hyperframes/producer` — same code path as the CLI and embedded preview mode
- Removed ~70 lines of SSE proxy streaming code, replaced with the same ~20-line in-process pattern used everywhere else
## DX improvement
**Before:** `pnpm dev` + `npx tsx packages/producer/src/public-server.ts` (two terminals, easy to forget)
**After:** `pnpm dev` (renders work immediately)
## Testing
Verified manually: open studio via `pnpm dev`, navigate to a project, click Export — renders complete with live progress updates, no separate server needed.
## Summary
- Add render queue panel with progress tracking, download, and delete actions
- Restructure App layout: home page with project picker, session-based routing
- Add ExpandOnHover component for preview-on-hover interactions (uses motion/react)
- CompositionsTab now supports hover preview with expanded iframe view
- Vite config: guard setInterval cleanup to dev-only (fixes CI build timeout)
- Add favicon and update studio package deps
## Test plan
- [x] Render queue shows progress, completes, and allows download
- [x] Home page lists projects and navigates to session view
- [x] ExpandOnHover shows expanded preview on mouse hover with spring animation
- [x] `vite build` exits cleanly (no hanging process from setInterval)
