Connectors are objects used to create link between two points, nodes or ports to represent the relationships between them.
Connector can be created by defining the source and target point of the connector. The path to be drawn can be defined with a collection of segments. To explore the properties of a connector
, refer to Connector Properties
.
The sourcePoint
and targetPoint
properties of connector allow you to define the end points of a connector.
The following code example illustrates how to add a connector through connector collection.
import * as React from "react";
import * as ReactDOM from "react-dom";
import { DiagramComponent } from "@syncfusion/ej2-react-diagrams";
let connectors = [{
// Name of the connector
id: "connector1",
style: {
strokeColor: '#6BA5D7',
fill: '#6BA5D7',
strokeWidth: 2
},
targetDecorator: {
style: {
fill: '#6BA5D7',
strokeColor: '#6BA5D7'
}
},
// Sets source and target points
sourcePoint: {
x: 100,
y: 100
},
targetPoint: {
x: 200,
y: 200
}
}];
ReactDOM.render(<DiagramComponent id="diagram" width={'100%'} height={'600px'} connectors={connectors}/>, document.getElementById("diagram"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import {
Diagram,
DiagramComponent,
ConnectorModel
} from "@syncfusion/ej2-react-diagrams";
let connectors: ConnectorModel[] = [{
// Name of the connector
id: "connector1",
style: {
strokeColor: '#6BA5D7',
fill: '#6BA5D7',
strokeWidth: 2
},
targetDecorator: {
style: {
fill: '#6BA5D7',
strokeColor: '#6BA5D7'
}
},
// Sets source and target points
sourcePoint: {
x: 100,
y: 100
},
targetPoint: {
x: 200,
y: 200
}
}];
ReactDOM.render( <DiagramComponent id="diagram"
width = {
'100%'
}
height = {
'600px'
}
connectors = {
connectors
}
/>, document.getElementById("diagram") );
Connectors can be added at runtime by using public method, diagram.add
and can be removed at runtime by using public method, diagram.remove
.
The following code example illustrates how to add connector at runtime.
import * as React from "react";
import * as ReactDOM from "react-dom";
import { DiagramComponent } from "@syncfusion/ej2-react-diagrams";
let diagramInstance;
let connectors = [{
id: 'connector1',

},

}
},
sourcePoint: {
x: 100,
y: 100
},
targetPoint: {
x: 200,
y: 200
}
}];
ReactDOM.render(<DiagramComponent id="diagram" ref={diagram => (diagramInstance = diagram)} width={'100%'} height={'600px'} created={() => {
// Adds to the Diagram
diagramInstance.add(connectors);
// Remove from the diagram
diagramInstance.remove(connectors);
}}/>, document.getElementById("diagram"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import {
Diagram,
DiagramComponent,
ConnectorModel
} from "@syncfusion/ej2-react-diagrams";
let diagramInstance: DiagramComponent;
let connectors: ConnectorModel = [{
id: 'connector1',
style: {
strokeColor: '#6BA5D7',
fill: '#6BA5D7',
strokeWidth: 2
},
targetDecorator: {
style: {
fill: '#6BA5D7',
strokeColor: '#6BA5D7'
}
},
sourcePoint: {
x: 100,
y: 100
},
targetPoint: {
x: 200,
y: 200
}
}];
ReactDOM.render( <DiagramComponent id="diagram" ref={diagram => (diagramInstance = diagram)}
width = {
'100%'
}
height = {
'600px'
}
created = {
() => {
// Adds to the Diagram
diagramInstance.add(connectors)
// Remove from the diagram
diagramInstance.remove(connectors)
}
}
/>, document.getElementById("diagram") );
Connectors can be predefined and added to the symbol palette. You can drop those connectors into the diagram, when required.
For more information about adding connectors from symbol palette, refer to Symbol Palette
.
Connectors can be interactively drawn by clicking and dragging on the diagram surface by using drawingObject
.
For more information about drawing connectors, refer to Draw Connectors
.
Various connector properties such as sourcePoint
, targetPoint
, style
, sourcePortID
, targetPortID
, etc., can be updated at the runtime.
The following code example illustrates how to update a connector’s source point, target point, styles properties at runtime.

The path of the connector is defined with a collection of segments. There are three types of segments.
To create a straight line, specify the type
of the segment as straight and add a straight segment to segments
collection and need to specify type
for the connector. The following code example illustrates how to create a default straight segment.

Orthogonal segments is used to create segments that are perpendicular to each other.
Set the segment type
as orthogonal to create a default orthogonal segment and need to specify type
. The following code example illustrates how to create a default orthogonal segment.
Multiple segments can be defined one after another. To create a connector with multiple segments, define and add the segments to connector.segments
collection. The following code example illustrates how to create a connector with multiple segments.

Note: You need to mention the segment type as same as what you mentioned in connector type. There should be no contradiction between connector type and segment type.
Orthogonal segments are automatically re-routed, in order to avoid overlapping with the source and target nodes. The following preview illustrates how orthogonal segments are re-routed.

Bezier segments are used to create curve segments and the curves are configurable either with the control points or with vectors.
To create a bezier segment, the segment.type
is set as bezier
and need to specify type
for the connector. The following code example illustrates how to create a default bezier segment.

The diagram Provides support to flip the connector. The flip
is performed to give the mirrored image of the original element.
The flip types are as follows:
Horizontal
is used to interchange the connector source and target x points.Vertical
is used to interchange the connector source and target y points.Both
is used to interchange the source point as target point and target point as source pointimport * as React from "react";

Line bridging creates a bridge for lines to smartly cross over the other lines, at points of intersection. By default, bridgeDirection
is set to top. Depending upon the direction given bridging direction appears.
Bridging can be enabled/disabled either with the connector.constraints
or diagram.constraints
. The following code example illustrates how to enable line bridging.

Note: You need to inject connector bridging module into the diagram.
The bridgeSpace
property of connectors can be used to define the width for line bridging.
Limitation: Bezier segments do not support bridging.
Corner radius allows to create connectors with rounded corners. The radius of the rounded corner is set with the cornerRadius
property.

addInfo
property of connectors allow you to maintain additional information to the connectors.let connectors: ConnectorModel[] = [{
id: 'connector1',
// Defines the information about the connector
addInfo: 'centralconnector',
type: 'Straight',
sourceID: 'Transaction',
targetID: 'Verification'
}];
The connectors zIndex
property specifies the stack order of the connector. A connector with greater stack order is always in front of a connector with a lower stack order.
The following code illustrates how to render connector based on the stack order.
import * as React from "react";
import * as ReactDOM from "react-dom";

Line Routing is used to avoid the overlapping of nodes and connectors. Connectors are the most important elements of a diagram used to show the flow and relationship between shapes in the flowcharts, organizational charts, and hierarchy diagrams. Line Routing provides the flexibility to re-route the diagram connectors. A connector will frequently re-route itself when a shape moves next to it.
Note: You need to inject line routing module into the diagram. Line routing is applicable only for orthogonal segment of connector.
The following code illustrates how the automatic line routing is enabled for diagram.
import * as React from "react";
import * as ReactDOM from "react-dom";
import { DiagramComponent, Inject, LineRouting, DiagramConstraints, } from "@syncfusion/ej2-react-diagrams";
//Initializes the nodes for the diagram
let nodes = [
{ id: 'shape1', offsetX: 100, offsetY: 100, width: 120, height: 50 },
{ id: 'shape2', offsetX: 300, offsetY: 300, width: 120, height: 50 },
{ id: 'shape3', offsetX: 150, offsetY: 200, width: 120, height: 50 }
];
//Initializes the connector for the diagram
let connectors = [
{ id: 'connector', sourceID: 'shape1', targetID: 'shape2', type: 'Orthogonal' }
];
ReactDOM.render(<DiagramComponent id="diagram" width={"100%"} height={"700px"} nodes={nodes} connectors={connectors} constraints={DiagramConstraints.Default | DiagramConstraints.LineRouting} getNodeDefaults={(node) => {
