How to Prevent Node Rotation in Javascript Diagram?

In the Syncfusion® JavaScript Diagram we have the flexibility to enable or disable specific behaviors of nodes through the use of NodeConstraints.

To prevent the rotation of a node in Diagram, we can use the Rotate NodeConstraint and disable it using the Bitwise ‘&~’ (XOR) operator

// Set the constraints for the node as Rotate and disable it
constraints: ej.diagrams.NodeConstraints.Default & ~ej.diagrams.NodeConstraints.Rotate 

Below is a code example demonstrating how to prevent rotation in node

var node = [
 {
   offsetX: 250,
   offsetY: 250,
   width: 100,
   height: 100,
   // Disable the Rotate NodeConstraint
   constraints: ej.diagrams.NodeConstraints.Default & ~ej.diagrams.NodeConstraints.Rotate,
 },
];
// Initialize Diagram component
var diagram = new ej.diagrams.Diagram(
 {
   width: '100%',
   height: '600px',
   nodes: node,
 },
 '#element'
);
