How to prevent node resize in Javascript platform

In the Syncfusion® JavaScript Diagram , by using the NodeConstraints, we can enable or disable certain features of nodes.

To prevent node resizing in the Diagram, use resize constraints.

// Set constraints as resize for Node
constraints: ej.diagrams.NodeConstraints.Default & ~ej.diagrams.NodeConstraints.Resize 

Set the constraints as follows for the node:

var nodes = [
   {
       id: "heptagon",
       offsetX: 200, offsetY: 160,
       width: 100, height: 100,
       shape: { type: 'Basic', shape: 'Heptagon' },
       annotations: [{ content: 'Resize = False' }],
       constraints: ej.diagrams.NodeConstraints.Default & ej.diagrams.NodeConstraints.Resize
   },
]; 

You can find a working example of this implementation in the provided sample on StackBlitz.
