dmn-moddle

Read and write DMN 1.3 files in NodeJS and the browser.

dmn-moddle uses the DMN specification to validate the input and produce correct DMN XML. The library is built on top of moddle and moddle-xml.

Usage

Get the library via npm package. Consume it in NodeJS or bundle it using your favorite build tool.

import { DmnModdle } from 'dmn-moddle';

const moddle = new DmnModdle();

const xmlStr =
  '<?xml version="1.0" encoding="UTF-8"?>' +
    '<definitions xmlns="https://www.omg.org/spec/DMN/20191111/MODEL/" ' +
                 'id="Definitions_1" ' +
                 'namespace="http://camunda.org/schema/1.0/dmn">' +
      '<decision id="Decision_1" name="Decision" />' +
    '</definitions>;


const {
  rootElement: definitions
} = await moddle.fromXML(xmlStr);

// update id attribute
definitions.set('id', 'NEW ID');

// add a root element
const dmnDecision = moddle.create('dmn:Decision', { id: 'MyDecision' });
definitions.get('drgElement').push(dmnDecision);

// xmlStrUpdated contains new id and the added process
const {
  xml: xmlStrUpdated
} = await moddle.toXML(definitions);
