Bpmn shapes in EJ2 JavaScript Diagram control
30 Jun 20244 minutes to read
BPMN shapes are used to represent the internal business procedure in a graphical notation and enable you to communicate the procedures in a standard manner. To create a BPMN shape, in the node property shape, type should be set as “bpmn” and its shape should be set as any one of the built-in shapes. The following code example illustrates how to create a simple business process.
NOTE
If you want to use BPMN shapes in diagram, you need to inject BpmnDiagrams in the diagram.
var node = {
// Position of the node
offsetX: 250,
offsetY: 250,
// Size of the node
width: 100,
height: 100,
shape: {
type: 'Bpmn', shape: 'Event',
event: { event: 'End' }
},
};
// initialize Diagram component
var diagram = new ej.diagrams.Diagram({
width: '100%', height: '600px'
}, '#element');
diagram.add(node);
