Export Diagrams.net diagrams during Dendron site publishing

Node module for exporting Diagrams.net (Draw.io) diagrams embedded in a published Dendron site to SVG.

Usage

Embed your diagrams in your notes as if they were images:

![My awesome diagram](assets/diagrams/my.awesome.diagram.drawio)

If your diagram has multiple pages, specify the page number (zero-indexed; defaults to 0) in the URL:

![My awesome diagram](assets/diagrams/my.awesome.diagram.drawio#3)

Installation

From the root of your Dendron workspace (where the dendron.code-workspace and dendron.yml files are), install the plugin:

npm install --save-dev dendron-publish-drawio

Publishing a Dendron site involves running the following commands:

npx dendron publish init
npx dendron publish build --wsRoot . --vault public --sitemap
cd .next/
npm run export

We need to add a step, between dendron publish build and npm run export:

npx dendron publish init
npx dendron publish build --wsRoot . --vault public --sitemap
npx dendron-publish-drawio
cd .next/
npm run export

Note that if you customise Dendron's site:assetsPrefix option (or set it via --overrides=assetsPrefix=...) you'll need to set the DENDRON_ASSETS_PREFIX environment variable to the same value when running dendron-publish-drawio:

export DENDRON_ASSETS_PREFIX=/etc npx dendron-publish-drawio
