How to Hook GetNodeDefaults and GetConnectorDefaults in Vue Diagram?

GetNodeDefaults

getNodeDefaults is a method often we use in our Vue Diagram component to customize common properties of diagram nodes. It can return or allow you to set properties such as:

Node appearance: Size, shape, color, border, etc.
Node data structure: Initial attributes like width, height and etc.

GetConnectorDefaults

Similar to getNodeDefaults, getConnectorDefaults is also a method used to customize common properties of connectors in the diagram component. It allows you to set properties such as:

Connector appearance: Style, shape, line width, type etc.

Refer to the code sample to hook getNodeDefaults and getConnectorDefaults in org-chart layout:

<template>
 <ejs-diagram
   style="display: block"
   ref="diagramObj"
   id="diagram"
   :width="width"
   :height="height"
   :tool="tool"
   :layout="layout"
   :getNodeDefaults="getNodeDefaults"
   :getConnectorDefaults="getConnectorDefaults"
   :dataSourceSettings="dataSourceSettings"
 ></ejs-diagram>
</template>

// Sets default value for Node.
function getNodeDefaults(obj, diagram) {
 obj.backgroundColor = obj.data.color;
 obj.style = { fill: 'none', strokeColor: 'none', color: 'white' };
 obj.width = 120;
 obj.height = 30;
 return obj;
}

// Sets default value for Connector.
function getConnectorDefaults(connector, diagram) {
 if (connector.targetDecorator) connector.targetDecorator.shape = 'None';
 connector.type = 'Orthogonal';
 connector.constraints = 0;
 connector.cornerRadius = 0;
 return connector;
}

Below we have provided an example sample for nodeDefaults and connectorDefaults functions to customize the common properties of nodes and connectors in an organizational chart.
