Camunda moddle extensions for BPMN 2.0

camunda-bpmn-moddle

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

Usage

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

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

var camundaModdle = require('camunda-bpmn-moddle/resources/camunda');

var moddle = new BpmnModdle({ camunda: camundaModdle });

var serviceTask = moddle.create('bpmn:ServiceTask', {
  'javaDelegate': 'my.company.SomeDelegate'
});

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.

Execute the test via

npm test

Perform a complete build of the application via

npm run all

bpmn-js Extension

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

var BpmnJS = require('bpmn-js/lib/Modeler'),
    camundaExtensionModule = require('camunda-bpmn-moddle/lib'),
    camundaModdle = require('camunda-bpmn-moddle/resources/camunda');

var modeler = new BpmnJS({
    additionalModules: [
      camundaExtensionModule
    ],
    moddleExtensions: {
      camunda: camundaModdle
    }
  });

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