bpmn-js-transaction-boundaries

A bpmn-js extension to visualize transaction boundaries

Features

Visualize all transaction boundaries in a BPMN diagram.

This includes all BPMN elements that are wait states and have a boundary for incoming connections:

• Intermediate Catching Message Event
• Intermediate Catching Timer Event
• Intermediate Catching Signal Event
• Receive Task
• User Task
• Event Based Gateway

Furthermore all activities which have asynchronous continuations act as transaction boundaries. This is also valid for multi-instance activities.

Usage

Extend the bpmn-js modeler with the transaction boundaries module:

var BpmnModeler = require('bpmn-js/lib/Modeler');

var transactionBoundariesModule = require('bpmn-js-transaction-boundaries');

var canvas = $('#js-canvas');

var bpmnModeler = new BpmnModeler({
  container: canvas,
  additionalModules: [
    transactionBoundariesModule
  ]
});

bpmnModeler.importXML(xml, function(err) {

  if (err) {
      console.error(err);
    } else {
      var transactionBoundaries = bpmnModeler.get('transactionBoundaries');

      transactionBoundaries.show();
    }
  });
