NodeNote

NodeNote turns a plain Markdown file into a board of question/note cards inside VS Code — each card carries a status, holds tabbed answers, can be pinned to the top, links to other cards, and accepts pasted images. It's still ordinary Markdown underneath, so the same file stays readable in any editor (Obsidian included) and round-trips losslessly.

Made for capturing and triaging a stream of open questions: jot fast, mark today / important / parked, attach several answers, pin what matters, and link related cards.

Install

Search NodeNote in the Extensions view (Ctrl/Cmd+Shift+X) and click Install — or from a terminal:

code --install-extension Chuang.nodenote

Then right-click any .md → Open With… → NodeNote.

Prefer not to use the Marketplace? Build a .vsix from source (see Build & test) and run code --install-extension nodenote-<version>.vsix.

Use it

Do this	How
Add a card	`+ New question` / `+ New note` (bottom bar), or Shift+Enter in a cell to commit and start the next
Switch type	the Q / N button on a card
Set status	the 🏷 button → important · today · open · answered · parked
Add answers	the + on a question; answers are tabs with editable labels (`pro`, `con`, …)
Pin	the pin button — the card sticks, expanded, to the top while you scroll
Link cards	type `[[heading-or-id]]` → clickable chip; the target shows a "Referenced by" backlink
Paste an image	paste into a body → saved to an `assets/` folder, inserted as `![](https://github.com/ChuangYan2/nodenote/raw/HEAD/assets/…)`
Navigate	↑/↓ between cards, ←/→ between a card's answer tabs

Bodies render Markdown (bold, lists, code, links, images); click a body to edit the raw source, click away to render. Non-image pastes are inserted as plain text (formatting stripped; LaTeX/math kept verbatim).

It's just Markdown

A card is a heading; an invisible  comment carries its metadata; answers are sub-headings linked by parent:

<!-- inbox: type=question; status=today,important; id=q1 -->
## How does FMCW range resolution depend on chirp bandwidth?

Want the clean derivation plus the practical ADC-rate limit.

<!-- inbox: type=answer; parent=q1 -->
### bandwidth

Range resolution `Δr = c / (2·B)` — set only by sweep bandwidth `B`.

<!-- inbox: type=answer; parent=q1 -->
### ADC limit

In practice capped by the ADC sample rate.

Open that with the plain text editor and it's clean Markdown; open it with NodeNote and it's a question card with two answer tabs. See examples/sample.md for a fuller file, and APPLICATION_NOTES.md for the format and workflows.

Build & test

npm install
npm run compile     # tsc → out/
npm run bundle      # esbuild web bundle
npm run lint
npm run test:core   # fast unit tests for the core (no VS Code needed)

The parser / serializer / view-model is a framework-agnostic core in src/core/ (tested with Node's built-in runner); the UI is a webview custom editor in src/editor.ts + media/editor.html.
