Hello everyone!
I'm trying to get the diamond node model demo working, but it gives me an error using it as written when running it through create-react-app's npm start script
Error: Cannot find factory with type [diamond]
More specifically I'm trying to use this with the drag and drop demo, and I've got it showing up in the tray on the left hand side, but when I drag it on to the canvas I get the error
How do you let your app know how to find the factory for it?

Got it! Instead of defining engine as new CreateEngine, I needed to use this.props.app.getDiagramEngine()
Hey there - it seems like the repo has quite a few open issues and hasnt been updated in 20 days - is this project dying? Not trying to be negative, but is project storm working on this anymore?

@dylanvorster @renato-bohler If either of you have some consulting hours available wondering if you're available and interested in adding an enhanced change-detection feature to the latest version, if possible. Pinging @renato-bohler because you tried to explain to me what to do but I'm just too slow (projectstorm/react-diagrams#819) and @dylanvorster because well gosh you made this awesome thing.
Hi Guys, Does anyone know how to update the position of ports after dynamically adding/removing ports to a node? I saw some mention of calling the recalculatePortsVisually method on the DiagramEngine but I cannot find any such method. I have also tried calling port.reportPosition() but does not seem to update the ports position either. I am using v6.6.1 of the library.
how to remove all node and link in model ?

Hi, I am facing huge performance issue while dragging link in smart routing. Any solution for that?
Igor Levdansky

Try to run simple example and get:

Uncaught TypeError: a.default is not a constructor
    at l.componentDidMount (index.umd.js:16:687)
    at commitLifeCycles (react-dom.development.js:20664:24)

Any ideas?

Hey all, does anyone know how to change the node draggable area? At the moment the whole node is draggable which is causing an issue if you want to highlight text on it. Ideally we'd disable the drag event when you're selecting text on the node, or set the drag event to a specific part of the node (e.g. a toolbar). Has anyone tried something similar?

hello,i want to know how to change border and color of the node ?
I am trying to use the projectstorm react diagram library, so far I have managed to get something working in a demo project. But this I now want to use in my actual work project where they build react widget plugins, unfortunately I am a novice in react as well as typescript and my apologies if it is obvious that I know very little, I did the demo app by creating a react app in the usual way with npx create-react-app my-app, had to add some compiler options but all started working in the end. Then I trasnferred it to my work project but here I run into issues, it is a typescript react project and due to my limited knowledge I am not sure what is causing this issue, but the issue is that it is complaining about circular dependencies in the projectstorm diagram library. This is odd for me that it did not complain in the demo app but in this project which I created with a scaffolding tool provided to me for the IDE framework we are working in (a low-code framework), but to the eye the structure looks the same as my demo app, I installed projectstorm react digram in the same way. What in the coniler or setup will cause this circular dependency to be picked up as an error and how can I disable it? Obviously there is something setup differently but I do not know where to start looking. This is the 3 circular dependency errors:
Error: Circular dependency: node_modules/@projectstorm/geometry/dist/Polygon.js -> node_modules/@projectstorm/geometry/dist/Rectangle.js -> node_modules/@projectstorm/geometry/dist/Polygon.js
Error: Circular dependency: node_modules/@projectstorm/react-diagrams/node_modules/@projectstorm/react-diagrams-routing/dist/link/PathFindingLinkFactory.js -> node_modules/@projectstorm/react-diagrams/node_modules/@projectstorm/react-diagrams-routing/dist/link/PathFindingLinkModel.js -> node_modules/@projectstorm/react-diagrams/node_modules/@projectstorm/react-diagrams-routing/dist/link/PathFindingLinkFactory.js

Hi I am new to the tech stack sorry if this question is a little silly - I am wondering how we can store a modifiable value (say, an int) in a node and allow modification onDoubleClick, do we have to create customized nodes in order to do that? Thanks!
