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 { Component, ViewEncapsulation, ViewChild } from '@angular/core';
import { DiagramComponent, Diagram, BpmnDiagrams, NodeModel, BpmnShapeModel } from '@syncfusion/ej2-angular-diagrams';
@Component({
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 { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { DiagramModule, BpmnDiagramsService } from '@syncfusion/ej2-angular-diagrams';

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
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 |

The BPMN shapes and its types are explained as follows.
An event
is notated with a circle and it represents an event in a business process. The type of events are as follows:
* Start
* End
* Intermediate
The event property of the node allows you to define the type of the event. The default value of the event is start. The following code example illustrates how to create a BPMN event.

Event triggers are notated as icons inside the circle and they represent the specific details of the process. The trigger
property of the node allows you to set the type of trigger and by default, it is set as none. The following table illustrates the type of event triggers.

Gateway is used to control the flow of a process and it is represented as a diamond shape. To create a gateway, the shape property of the node should be set as “gateway” and the gateway
property can be set with any of the appropriate gateways. The following code example illustrates how to create a BPMN Gateway.
import { Component, ViewEncapsulation, ViewChild } from '@angular/core';
import { DiagramComponent, Diagram, NodeModel, BpmnShapeModel } from '@syncfusion/ej2-angular-diagrams';

})
export class AppComponent {
@ViewChild("diagram")
public diagram: DiagramComponent;
public shape: BpmnShapeModel = {
type: 'Bpmn',
shape: 'Event',
// Sets type of the gateway as None
gateway: {

}
},
public getNodeDefaults(node: NodeModel): NodeModel {
node.height = 100;
node.width = 100;
return node;
}
}
import { NgModule } from '@angular/core';

The activity
is the task that is performed in a business process. It is represented by a rounded rectangle.
There are two types of activities. They are listed as follows:
To create a BPMN activity, set the shape as activity. You also need to set the type of the BPMN activity by using the activity property of the node. By default, the type of the activity is set as task. The following code example illustrates how to create an activity.
import { Component, ViewEncapsulation, ViewChild } from '@angular/core';

The different activities of BPMN process are listed as follows.
The task
property of the node allows you to define the type of task such as sending, receiving, user based task, etc. By
default, the type
property of task is set as none. The following code illustrates how to create different types of
BPMN tasks.
The events property of tasks allow to represent these results as an event attached to the task.

The different types of subprocess are as follows:
A subprocess is defined as an event subprocess, when it is triggered by an event. An event subprocess is placed within another subprocess which is not part of the normal flow of its parent process. You can set event to a subprocess with the event
and trigger
property of the subprocess. The type
property of subprocess allows you to define the type of subprocess whether it should be event subprocess or transaction subprocess.

transaction
is a set of activities that logically belong together, in which all contained activities must complete their parts of the transaction; otherwise the process is undone. The execution result of a transaction is one of Successful Completion, Unsuccessful Completion (Cancel), and Hazard (Exception). The events
property of subprocess allows to represent these results as an event attached to the subprocess.import { Component, ViewEncapsulation, ViewChild } from '@angular/core';

A data object represents information flowing through the process, such as data placed into the process, data resulting from the process, data that needs to be collected, or data that must be stored. To define a data object
, set the shape as DataObject and the type property defines whether data is an input or an output. You can create multiple instances of data object with the collection property of data.

BPMN Flows
are lines that connects BPMN flow objects.
BPMN Association
flow is used to link flow objects with its corresponding text or artifact. An association is represented as a dotted graphical line with opened arrow. The types of association are as follows:
The association property allows you to define the type of association. The following code example illustrates how to create an association.
import { Component, ViewEncapsulation, OnInit, ViewChild } from '@angular/core';
import { DiagramComponent, BpmnFlowModel, PointModel } from '@syncfusion/ej2-angular-diagrams';
@Component({
selector: "app-container",
template: `<ejs-diagram id="diagram" width="100%" height="580px">
<e-connectors>
<e-connector id='connector' type='Orthogonal' [sourcePoint]='sourcePoint' [targetPoint]='targetPoint' [shape]='shape'>
</e-connector>
</e-connectors>
</ejs-diagram>`,
encapsulation: ViewEncapsulation.None
})
export class AppComponent {
@ViewChild("diagram")
public sourcePoint: PointModel;
public targetPoint:PointModel;
public shape: BpmnFlowModel;
ngOnInit(): void {
this.sourcePoint = { x: 100, y: 100 };
this.targetPoint = { x: 200, y: 200 };
this.shape = {
type: 'Bpmn',
flow: 'Association',
