Zeebe moddle extensions for BPMN 2.0

Usage no npm install needed!

<script type="module">
  import zeebeBpmnModdle from 'https://cdn.skypack.dev/zeebe-bpmn-moddle';




This project defines the Zeebe namespace extensions for BPMN 2.0 as a moddle descriptor.


Use it together with bpmn-moddle to validate Zeebe BPMN 2.0 extensions.

var BpmnModdle = require('bpmn-moddle');

var zeebeModdle = require('zeebe-bpmn-moddle/resources/zeebe.json');

var moddle = new BpmnModdle({ zeebe: zeebeModdle });

var taskDefinition = moddle.create('zeebe:TaskDefinition', {
  type: 'payment-service',
  retries: '5'

var serviceTask = moddle.create('bpmn:ServiceTask', {
  extensionElements: [ taskDefinition ]

bpmn-js Extension

We include an extension that makes bpmn-js copy and replace mechanisms aware of Zeebe properties.

var BpmnJS = require('bpmn-js/lib/Modeler'),
    zeebeExtensionModule = require('zeebe-bpmn-moddle/lib'),
    zeebeModdle = require('zeebe-bpmn-moddle/resources/zeebe');

var modeler = new BpmnJS({
    additionalModules: [
    moddleExtensions: {
      zeebe: zeebeModdle

This extension hooks into the copy mechanism provided by the BPMN editor and ensures Zeebe properties are kept and or dropped on copy and element replace.
