Node API

import { readFile, writeFile } from 'node:fs/promises';
import { renderToSVG } from 'workflow-render/core';

const json = JSON.parse(await readFile('workflow.json', 'utf8'));
const { svg, warnings } = await renderToSVG(json);

await writeFile('workflow.svg', svg);

The package is ESM only and ships its own types.

`renderToSVG(json, options?)`

Returns { svg, warnings }. It rejects when the input is not a workflow or an execution.

Option	Meaning	Default
`embedFonts`	Embed the fonts in the SVG so it renders the same everywhere	`true`
`remoteImages`	Allow sticky-note images from other hosts	`false`
`icons`	Use your own icon catalogue instead of the bundled one	bundled
`subtitles`	Use your own subtitle catalogue instead of the bundled one	bundled

Lower-level exports

The same subpath exports the individual steps, for callers that want to work with the model between them.

Export	What it does
`parseInput`	Turn workflow or execution JSON into the canvas model
`layout`	Position the model
`renderSVG`	Draw a positioned model
`exportSVG`	Produce a standalone SVG, fonts included
`loadIcons`, `loadDescriptions`, `loadSubtitles`	Load the bundled n8n data

Using a different n8n extraction

Set WORKFLOW_RENDER_DATA to a directory shaped like the package's own data/ folder.

WORKFLOW_RENDER_DATA=./my-data npx workflow-render export workflow.json -o workflow.svg
