bpmn-moddle


Read and write BPMN 2.0 diagram files in NodeJS and the browser.

__bpmn-moddle__ uses the BPMN 2.0 meta-model to validate the input and produce correct BPMN 2.0 XML.

Usage

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

``javascript
import { BpmnModdle } from 'bpmn-moddle';

const moddle = new BpmnModdle();

const xmlStr =
'' +
' 'id="empty-definitions" ' +
'targetNamespace="http://bpmn.io/schema/bpmn">' +
'';


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

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

// add a root element
const bpmnProcess = moddle.create('bpmn:Process', { id: 'MyProcess_1' });
definitions.get('rootElements').push(bpmnProcess);

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