React-Flow: Can you pass props to a custom node in React-Flow?

I am using React-Flow in order to visualise a tree hierarchy of components in React. And whenever you create a custom node in React-Flow, you use it in the tree like that:

  <ReactFlow
      onLoad={onLoadTree}
      elements={nodesAndEdges}
      nodeTypes={{ reactComponent: ComponentNode }}

Which makes it impossible to pass props. Let's say that I want to pass something, then I would be able to do that if the syntax was like reactComponent: <ComponentNode myProps={myProps} />. Has anyone worked with this technology before and knows if it's somehow possible to pass props to a custom node? :) Thanks!

You can do like this

const YourComponent = () => {
  const componentNode = { reactComponent: (props) => <ComponentNode myProp="myProps" {...props} />};

  return (
    <ReactFlow
      onLoad={onLoadTree}
      elements={nodesAndEdges}
      nodeTypes={componentNode}
    />
  );
};

Here through props you get the predefined props like data, id etc.

It seems you can pass props in data property of node.

You can pass any data you want in the data property section when creating a new node :

const newNode = {
  ...nodeProps,
  data: {
    myCustomProps: "test",
  },
}
