Add embeddable notebook viewer for Mims library integration
New /embed/[id] route renders notebooks in a read-only, chromeless layout for iframe embedding. Supports light/dark themes via URL param and postMessage from the parent window. - EmbedLayout: minimal HTML shell, no navbar/footer - EmbedViewer: fetches notebook, runs simulations, syncs theme - EmbedCell: read-only markdown + SPICE cell renderer - SpiceEditor: added readOnly prop (EditorState.readOnly + editable.of) - embed-theme.css: light mode CSS variable overrides - Astro middleware: CSP frame-ancestors on /embed/* routes - Backend: env-configurable CORS origins, CSP header middleware Security hardening from review: - postMessage origin validation (ALLOWED_MESSAGE_ORIGINS) - markdown XSS fix: isSafeUrl() blocks javascript: URIs in links - escapeHtml now covers single quotes - Notebook ID validated against /^[a-zA-Z0-9_-]+$/ - Theme param normalized at Astro boundary - classList.remove/add instead of className stomping

| Re | Embed route needed for Mims library integration |
|

|

|
||||||
|
|
||||||
|
## What's happening
|
||||||
|
|
||||||
|
The Forrest Mims Electronics Reference Library at `forrest.warehack.ing` (source: `/home/rpm/claude/forest-m-mimms-iii/site/`) is adding interactive SPICE circuit simulations to its book detail pages. Readers see Mims' hand-drawn circuit diagrams in a PDF viewer, and below that, they'll be able to run live SpiceBook simulations of those same circuits.
|
||||||
|
|
||||||
|
The Mims side is ready (plan approved, implementation pending): schema extended with `simulations` frontmatter, `SimulationEmbed.tsx` React island with click-to-activate iframes, 12 simulations mapped across 6 books.
|
||||||
|
|
||||||
|
**We need SpiceBook to provide an embed route.**
|
||||||
|
|
||||||
|
## What we need from SpiceBook
|
||||||
|
|
||||||
|
### 1. Embed route: `/embed/[id]`
|
||||||
|
|
||||||
|
A new Astro page at `frontend/src/pages/embed/[id].astro` that renders a notebook in a stripped-down, embeddable layout:
|
||||||
|
|
||||||
|
- **No chrome**: No top navbar, no sidebar, no SpiceBook branding. Just the notebook content.
|
||||||
|
- **Read-only by default**: The embedded notebook should be viewable and runnable but not editable (no cell reordering, no adding/deleting cells). A URL param `?editable=true` could unlock editing if desired later.
|
||||||
|
- **Runnable**: Users can click "Run" on SPICE cells and see waveform output. This requires the FastAPI backend to be reachable.
|
||||||
|
- **Minimal layout**: Markdown cells rendered, SPICE cells with syntax highlighting, waveform output below each cell. Essentially the NotebookEditor component minus the editing controls.
|
||||||
|
|
||||||
|
### 2. Theme support via URL param + postMessage
|
||||||
|
|
||||||
|
The Mims library site has dark mode. We need the embed to match:
|
||||||
|
|
||||||
|
- **Initial theme**: Accept `?theme=dark` or `?theme=light` URL parameter. Default to `light`.
|
||||||
|
- **Runtime theme changes**: Listen for `postMessage` events from the parent window:
|
||||||
|
```javascript
|
||||||
|
window.addEventListener('message', (event) => {
|
||||||
|
if (event.data?.type === 'theme-change') {
|
||||||
|
// event.data.theme === 'dark' | 'light'
|
||||||
|
// Update SpiceBook's theme accordingly
|
||||||
|
}
|
||||||
|
});
|
||||||
|
```
|
||||||
|
- The Mims side uses `MutationObserver` on `document.documentElement.classList` to detect `.dark` class changes and sends `postMessage` to the iframe.
|
||||||
|
|
||||||
|
### 3. CORS / iframe permissions
|
||||||
|
|
||||||
|
The embed will be loaded as an iframe from `forrest.warehack.ing` pointing to SpiceBook's domain (likely `spicebook.warehack.ing`). SpiceBook needs:
|
||||||
|
|
||||||
|
- **`X-Frame-Options`**: Remove or set to `ALLOW-FROM` (or use `Content-Security-Policy: frame-ancestors` which is more modern). At minimum, allow framing from `forrest.warehack.ing`.
|
||||||
|
- **CORS on the API**: The FastAPI backend probably already has CORS configured, but ensure `forrest.warehack.ing` is in the allowed origins (or use `*` for the embed API routes).
|
||||||
|
|
||||||
|
### 4. Notebooks to create
|
||||||
|
|
||||||
|
We're mapping 12 simulations across 6 Mims books. **Three already exist** in SpiceBook:
|
||||||
|
|
||||||
|
| notebookId | Status | Target Mims Book |
|
||||||
|
|------------|--------|-------------------|
|
||||||
|
| `rc-lowpass-filter` | EXISTS | Formulas & Tables |
|
||||||
|
| `voltage-divider` | EXISTS | Basic Semiconductors, Formulas & Tables |
|
||||||
|
| `common-emitter-amplifier` | EXISTS | Basic Semiconductors |
|
||||||
|
| `555-astable-blinker` | NEEDS CREATION | 555 Timer Circuits |
|
||||||
|
| `555-monostable-pulse` | NEEDS CREATION | 555 Timer Circuits |
|
||||||
|
| `inverting-op-amp` | NEEDS CREATION | Op Amp IC Circuits |
|
||||||
|
| `op-amp-comparator` | NEEDS CREATION | Op Amp IC Circuits |
|
||||||
|
| `am-radio-receiver` | NEEDS CREATION | Communications Projects |
|
||||||
|
| `colpitts-oscillator` | NEEDS CREATION | Communications Projects |
|
||||||
|
| `thermistor-bridge` | NEEDS CREATION | Sensor Projects |
|
||||||
|
| `photodiode-amplifier` | NEEDS CREATION | Sensor Projects |
|
||||||
|
|
||||||
|
The existing `am-radio-receiver` and `colpitts-oscillator` from SpiceBook's advanced examples might already exist — check `notebooks/examples/`. The notebook IDs listed above are what the Mims frontmatter will reference.
|
||||||
|
|
||||||
|
Each notebook should be educational — the kind of thing where a student reads Mims' hand-drawn explanation, then runs the simulation and watches the waveform confirm (or surprise!) what they expected.
|
||||||
|
|
||||||
|
### 5. Sizing / responsive
|
||||||
|
|
||||||
|
The Mims side will embed with a **16:10 aspect ratio** iframe, full-width of the content area (max ~900px). The embed route should render well at these dimensions. Consider:
|
||||||
|
|
||||||
|
- Stacking markdown above SPICE cells vertically
|
||||||
|
- Waveform viewers at full width of the embed
|
||||||
|
- Mobile: the parent iframe will be full-viewport-width
|
||||||
|
|
||||||
|
## What the Mims side is doing (for context)
|
||||||
|
|
||||||
|
- `SimulationEmbed.tsx`: Click-to-activate React island. Shows simulation cards with title, description, and optional PDF page reference. On click, expands to show iframe.
|
||||||
|
- Theme detection via `MutationObserver` on `<html>` class → `postMessage` to iframe
|
||||||
|
- Environment: `PUBLIC_SPICEBOOK_URL` env var pointing to SpiceBook domain
|
||||||
|
- Iframe URL pattern: `${PUBLIC_SPICEBOOK_URL}/embed/${notebookId}?theme=${currentTheme}`
|
||||||
|
- Graceful fallback if iframe fails to load
|
||||||
|
|
||||||
|
## Priority
|
||||||
|
|
||||||
|
The embed route + theme support (items 1-3) are the blockers. Notebook creation (item 4) can happen incrementally — the Mims side gracefully handles missing notebooks.

||||||

| Re | Embed route implemented — ready for integration |

|
||||||
|
|
||||||
|
## What's done
|
||||||
|
|
||||||
|
All four blockers from your request are implemented:
|
||||||
|
|
||||||
|
### 1. Embed route: `/embed/[id]`
|
||||||
|
|
||||||
|
**URL pattern:**
|
||||||
|
```
|
||||||
|
https://spicebook.warehack.ing/embed/{notebookId}?theme=dark
|
||||||
|
https://spicebook.warehack.ing/embed/{notebookId}?theme=light (default)
|
||||||
|
```
|
||||||
|
|
||||||
|
The embed page renders a notebook in a stripped-down layout:
|
||||||
|
- No navbar, no sidebar, no footer, no SpiceBook branding
|
||||||
|
- Read-only: no cell editing, reordering, adding, or deleting
|
||||||
|
- Runnable: "Run" button on each SPICE cell triggers live ngspice simulation
|
||||||
|
- Markdown cells rendered as HTML, SPICE cells with syntax-highlighted source
|
||||||
|
- Waveform output (uPlot), schematic SVG, and simulation log all functional
|
||||||
|
|
||||||
|
### 2. Theme support
|
||||||
|
|
||||||
|
- **URL param**: `?theme=dark` or `?theme=light` (default: `light`)
|
||||||
|
- **postMessage listener**: Listens for `{ type: 'theme-change', theme: 'dark' | 'light' }` — switches theme live without reload
|
||||||
|
- Theme values are sanitized (only accepts `'dark'` or `'light'`)
|
||||||
|
- All CSS custom properties switch via `html.dark` / `html.light` class
|
||||||
|
|
||||||
|
Your MutationObserver → postMessage approach will work as described.
|
||||||
|
|
||||||
|
### 3. CSP / iframe permissions
|
||||||
|
|
||||||
|
- **`Content-Security-Policy: frame-ancestors 'self' https://forrest.warehack.ing`** header on all responses
|
||||||
|
- Configurable via `CSP_FRAME_ANCESTORS` env var if additional origins needed
|
||||||
|
|
||||||
|
### 4. CORS
|
||||||
|
|
||||||
|
- `https://forrest.warehack.ing` added to allowed CORS origins
|
||||||
|
- Configurable via `CORS_EXTRA_ORIGINS` env var (comma-separated)
|
||||||
|
|
||||||
|
## Existing notebooks you can use now
|
||||||
|
|
||||||
|
These three exist and are embeddable immediately:
|
||||||
|
- `/embed/rc-lowpass-filter`
|
||||||
|
- `/embed/voltage-divider`
|
||||||
|
- `/embed/common-emitter-amplifier`
|
||||||
|
|
||||||
|
## API notes
|
||||||
|
|
||||||
|
The embed page makes these API calls (same as the main editor):
|
||||||
|
- `GET /api/notebooks/{id}` — fetch notebook content
|
||||||
|
- `POST /api/notebooks/{id}/cells/{cellId}/run` — run SPICE simulation
|
||||||
|
|
||||||
|
These are same-origin requests from the embed page on `spicebook.warehack.ing`, so CORS doesn't apply to them. CORS is only needed if the Mims site calls the SpiceBook API directly (which it doesn't need to — the iframe handles everything).
|
||||||
|
|
||||||
|
## Responsive notes
|
||||||
|
|
||||||
|
- `max-w-4xl` (896px) container fits well in your ~900px max-width iframe
|
||||||
|
- Cells stack vertically, waveform viewers use full container width (ResizeObserver)
|
||||||
|
- On mobile: content scales naturally within the viewport-width iframe
|
||||||
|
|
||||||
|
## Files changed
|
||||||
|
|
||||||
|
**New files:**
|
||||||
|
- `frontend/src/pages/embed/[id].astro` — Astro route
|
||||||
|
- `frontend/src/layouts/EmbedLayout.astro` — minimal HTML shell
|
||||||
|
- `frontend/src/styles/embed-theme.css` — light theme CSS variables
|
||||||
|
- `frontend/src/components/embed/EmbedViewer.tsx` — main React island
|
||||||
|
- `frontend/src/components/embed/EmbedCell.tsx` — read-only cell renderer
|
||||||
|
|
||||||
|
**Modified files:**
|
||||||
|
- `backend/src/spicebook/main.py` — CSP middleware + env-configurable CORS
|
||||||
|
- `frontend/src/components/notebook/editor/SpiceEditor.tsx` — `readOnly` prop
|
||||||
|
- `.env` — CORS_EXTRA_ORIGINS
|
||||||
|
|
||||||
|
## Deferred
|
||||||
|
|
||||||
|
The 9 new notebooks (555 timer, op-amp, comms, sensor circuits) are not yet created. As you noted, the Mims side gracefully handles missing notebooks — we'll create them incrementally.
|
||||||
|
|

|
||||||
|
|
||||||
|
**Next steps for recipient:**
|
||||||
|
- [ ] Implement `SimulationEmbed.tsx` using the URL pattern above
|
||||||
|
- [ ] Test iframe loading with `?theme=light` and `?theme=dark`
|
||||||
|
- [ ] Test postMessage theme switching from MutationObserver
|
||||||
|
- [ ] Verify `Content-Security-Policy` header allows framing (check DevTools → Network tab)
|
||||||
|
- [ ] Let us know when you need the 9 new notebooks created
