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


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

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

var nowjsModdle = require('nowjs-bpmn-moddle/resources/nowjs');

var moddle = new BpmnModdle({ nowjs: nowjsModdle });

var serviceTask = moddle.create('bpmn:ServiceTask', {
  'javaDelegate': ''

Building the Project

To run the test suite that includes XSD schema validation you must have a Java JDK installed and properly exposed through the JAVA_HOME variable.

bpmn-js Extension

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

var BpmnJS = require('bpmn-js/lib/Modeler'),
    nowjsExtensionModule = require('nowjs-bpmn-moddle/lib'),
    nowjsModdle = require('nowjs-bpmn-moddle/resources/nowjs');

var modeler = new BpmnJS({
    additionalModules: [
    moddleExtensions: {
      nowjs: nowjsModdle

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