noodle-embed

Embed a nanoodle workflow in any page. One ES module, zero dependencies. Drop a share link into a <noodle-embed> tag and readers see the workflow — nodes, wires, labels — rendered read-only right in your post, with an Open in nanoodle → button that loads the real thing on their canvas, ready to run or remix.

<script type="module" src="noodle-embed.mjs"></script>
<noodle-embed src="https://nanoodle.com/#g=H4sIAAAA..."></noodle-embed>

That's the whole integration.

Why this exists

A nanoodle share link carries the entire workflow inside the URL fragment — nothing is uploaded, nothing is hosted. That's great for privacy and terrible for previews: pasted into a blog post, the link is just a wall of base64. noodle-embed decodes that fragment locally in the reader's browser (no fetch, no analytics, nothing leaves the page — the same promise nanoodle itself makes) and draws the graph, so the workflow is visible where your readers already are.

Usage

<script type="module" src="noodle-embed.mjs"></script>

<!-- a workflow link (#g= / #j=) or an app link (#a=) -->
<noodle-embed src="https://nanoodle.com/#g=..."></noodle-embed>

<!-- taller canvas for stacked graphs (default 340, clamped 160–1200) -->
<noodle-embed src="https://nanoodle.com/play#a=..." height="480"></noodle-embed>

Attributes:

attribute	what it does
src	A nanoodle share URL, or a bare #g=... fragment. All four fragment tags are understood: #g= (gzip graph), #j= (plain graph), #a= (gzip app), #a=u (plain app). App embeds show the app's name.
height	Canvas height in px. Default 340, clamped to 160–1200.

Behavior worth knowing:

• Read-only viewer. Field contents (prompts, uploads) are never shown — only structure: node cards with their type emoji/label (or custom name) and the wires between them. Running happens one click away, in nanoodle.
• Graceful fallback. An undecodable src still renders the frame and the Open-in-nanoodle button — a broken preview never becomes a dead end.
• Full share URLs only. link.nanoodle.com short links can't be decoded without a network round-trip, so embed the full-length link (the graph is in the fragment). The share popover's copy button gives you exactly that.
• Self-contained. No external requests of any kind, so it works under strict CSPs (default-src 'self') and in offline docs.

Development

npm test          # node --test — decode, layout, fallback logic (Node ≥ 20)
open demo.html    # serve the folder and eyeball the element

The pure helpers (decodeShareUrl, layoutGraph, openUrl, TYPE_META) are exported for reuse and tests; the custom element registers itself only in browsers.

Roadmap

• Live run inside the embed via nanoodle-js (nanoodle/browser), bring-your-own-key — the engine already runs in browsers; the embed just needs a key affordance that meets the privacy bar.
• npm publish + CDN copy-paste snippet.
