bpmn-js Modeler + Properties Panel Example

This example uses bpmn-js and bpmn-js-properties-panel. It implements a BPMN 2.0 modeler that allows you to edit execution related properties via a properties panel.

About

This example is a node-style web application that builds a user interface around the bpmn-js BPMN 2.0 modeler.

Usage

Add the properties panel to your project:

npm install --save bpmn-js-properties-panel

Additionally, if you'd like to use Camunda BPM execution related properties, include the camunda-bpmn-moddle dependency which tells the modeler about camunda:XXX extension properties:

npm install --save camunda-bpmn-moddle

Now extend the bpmn-js modeler with two properties panel related modules, the panel itself and a provider module that controls which properties are visible for each element. Additionally you must pass an element via propertiesPanel.parent into which the properties panel will be rendered (cf. app/index.js for details).

var propertiesPanelModule = require('bpmn-js-properties-panel'),
    // providing camunda executable properties, too
    propertiesProviderModule = require('bpmn-js-properties-panel/lib/provider/camunda'),
    camundaModdleDescriptor = require('camunda-bpmn-moddle/resources/camunda');

var bpmnModeler = new BpmnModeler({
  container: '#js-canvas',
  propertiesPanel: {
    parent: '#js-properties-panel'
  },
  additionalModules: [
    propertiesPanelModule,
    propertiesProviderModule
  ],
  // needed if you'd like to maintain camunda:XXX properties in the properties panel
  moddleExtensions: {
    camunda: camundaModdleDescriptor
  }
});

Building the Example

You need a NodeJS development stack with npm and installed to build the project.

To install all project dependencies execute

npm install

Build the example using browserify via

npm run all

You may also spawn a development setup by executing

npm run dev

Both tasks generate the distribution ready client-side modeler application into the dist folder.

Serve the application locally or via a web server (nginx, apache, embedded).
