Embedding

You may embed dmn-to-image and use it as parts of your application:

const {
  convertAll
} = require('dmn-to-image');

await convertAll([
  {
    input: 'diagram.dmn',
    outputs: [
      'diagram.pdf',
      'diagram.png',
      'diagram.svg'
    ]
  }
]);

This renders the DMN diagram using dmn-js and exports it to the specified output files using Puppeteer.
