• Stretch - Stretches the diagram element throughout its immediate parent
• Left - Aligns the diagram element at the left of its immediate parent
• Right - Aligns the diagram element at the right of its immediate parent

Defaults to ‘Center’

id

string

Defines the unique id of the port

Defaults to ”

inEdges

string[]

Defines the collection of the objects that are connected to a particular port

Defaults to undefined

margin

MarginModel

Defines the space that the port has to be moved from its actual position

Defaults to new Margin(0,0,0,0)

outEdges

string[]

Defines the collection of the objects that are connected to a particular port

Defaults to undefined

pathData

• Square - Sets the decorator shape as Square
• Custom - Sets the decorator shape as Custom

Defaults to ‘Square’

style

ShapeStyleModel

Defines the appearance of the port

<div id='diagram'></div>

  let port: PointPortModel[] =
[{ id: 'port1', visibility: PortVisibility.Visible, shape: 'Circle', offset: { x: 0, y: 0 } },];
let nodes: NodeModel[] = [{
id: 'node1', width: 100, height: 100, offsetX: 100, offsetY: 100,
}];
nodes.ports = port;
let diagram: Diagram = new Diagram({
...
nodes : nodes,
...
});
diagram.appendTo('#diagram');

Defaults to {}

verticalAlignment

• Bottom - Aligns the diagram element at the bottom of its immediate parent
• Center - Aligns the diagram element at the center of its immediate parent
• Auto - Aligns the diagram element based on the characteristics of its immediate parent

Defaults to ‘Center’

visibility

PortVisibility

Defines the type of the port visibility

• Visible - Always shows the port
• Hidden - Always hides the port
• Hover - Shows the port when the mouse hovers over a node
• Connect - Shows the port when a connection end point is dragged over a node

Defaults to ‘Connect’

width

number
