Bpmn shapes in Angular Diagram component
21 Oct 20243 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.
import { DiagramModule, BpmnDiagramsService, DiagramComponent, NodeModel, BpmnShapeModel } from '@syncfusion/ej2-angular-diagrams'
import { Component, ViewEncapsulation, ViewChild } from '@angular/core';
@Component({
imports: [
DiagramModule
],
providers: [BpmnDiagramsService],
standalone: true,
selector: "app-container",
template: `<ejs-diagram #diagram id="diagram" width="100%" height="580px" [getNodeDefaults] ='getNodeDefaults'>
<e-nodes>
<e-node id='node1' [offsetX]=150 [offsetY]=150 [shape]='shape'></e-node>
</e-nodes>
</ejs-diagram>`,
encapsulation: ViewEncapsulation.None
})
export class AppComponent {
@ViewChild("diagram")
public diagram?: DiagramComponent;
public shape: BpmnShapeModel = {
type: 'Bpmn',
shape: 'Event',
// set the event type as End
event: {
event: 'End'
}
}
public getNodeDefaults(node: NodeModel): NodeModel {
node.height = 100;
node.width = 100;
return node;
}
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
Note : The default value for the property
shape
is “event”.
The list of BPMN shapes are as follows:
Shape | Image |
---|---|
Event | |
Gateway | |
Task | |
Message | |
DataSource | |
DataObject | |
Group |
The BPMN shapes and its types are explained as follows.
