npm distribution

Render Mermaid diagram text to SVG in Node.js without a browser. The engine runs in Rust. npm installs the matching optional platform package; keep optional dependencies enabled. No browser or WASM runtime is required.

import { Renderer } from '@ferrigura/core';
const diagrams = new Renderer();
const svg = diagrams.render('flowchart LR\nA[Hello] --> B[World]', {
  id: 'article-flow',
  colorScheme: 'auto',
});
console.log(svg);

render(text, config?, options?) renders one diagram. new Renderer(config?) resolves configuration once; reuse renderer.render(text, options?) for many blocks. Both return SVG synchronously and throw on engine errors. Give diagrams unique IDs when combining them in one document. SVG is not automatically JSX.

Supported platforms: macOS arm64; Linux x64/arm64 with glibc or musl; Windows x64/arm64. Node.js 22.13.0 or newer is required. The main package contains no native addon. See NOTICE.md for layout and bundled-font license texts.

This source introduces the npm distribution; registry bootstrap and Trusted Publishing setup must complete before installation from npm is available.
