This extension was written once as an April Fool's day demonstration.

Have a look, learn, get inspired. Do not use it, even though you could 🙏.

Extend bpmn-js to define tasks priorities while modeling.

• Color elements based on tp:color extension attribute
• Compute and display priorities based on color and task size
• Serializes the computed priority via the tp:priority for usage during process execution

Fetch it as a dependency via npm:

npm install bpmn-js-task-priorities

Use the modeler as part of your application:

var PriorityAwareModeler = require('bpmn-js-task-priorities/lib/PriorityAwareModeler');

var modeler = new PriorityAwareModeler();

modeler.importXML(annotatedBpmnXml, ...);

Or use the provided extension module with bpmn-js:

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

var prioritiesModule = require('bpmn-js-task-priorities/lib/priorities');

var modeler = new Modeler({
  additionalModules: [
    prioritiesModule
  ]
});

Specify tasks colors in XML and read the serialized tp:color and tp:priority extension attributes:

<definitions ... xmlns:tp="http://tp">
  <process>
    <task id="Task_1" tp:color="green" />
    <task id="Task_2" tp:color="red" tp:priority="100041" />
    ...
  </process>
</definitions>

npm install
npm run test:watch
