Quick start

npm install
npm run dev          # UI in a browser, http://localhost:1421
npm run tauri dev    # desktop window
npm test && npm run lint

Linux needs libwebkit2gtk-4.1-dev build-essential libssl-dev librsvg2-dev libxdo-dev pkg-config.

Open a file from the command line with erd-editor path/to/file.erd.json; a second launch hands its file to the running window.
