Fixed size nodes

Question

I'm trying to port a desktop app to the web using Diagram. The app simply "connect" fixed sized shapes loaded from specific libraries to other shapes, is there a way to create some"fixed size shape" so that the user cannot resize them but can move, rotate and snap them together?
Something similar to this:https://gojs.net/latest/samples/pipes.html

Thanks for your time.

Hi QED, 
 
By using the NodeConstraints we can able to restrict the node resize. To prevent the node from resizing remove resize constraints from node constraints. So that you cannot able to resize the node and able to drag, rotate the node. Please refer below code snippet for how to remove resize from node constraints 
 




let node: NodeModel = { 
    id: 'node1', width: 100, height: 100, offsetX: 100, offsetY: 100, annotations: [ { content: 'Node1'}], 
    constraints: NodeConstraints.Default & ~(NodeConstraints.Resize) 
 
};
